Abstract
Description
Technical Field
[0001] This application relates to the field of artificial intelligence technology, and in particular to methods, devices, electronic devices and storage media for the operation and control of intelligent agents. Background Technology
[0002] With the development of large language model agents, agent systems are now able to invoke external tools and execute multi-step tasks driven by user intent, such as reading or writing files, running system commands, accessing databases, and calling external interfaces. Existing agent execution modes mainly include reactive execution mode and post-planning execution mode. These execution modes typically rely on a "reasoning-action-observation" loop or pre-generate a list of steps for execution scheduling before the task begins, thereby improving the flexibility and predictability of multi-step tasks.
[0003] However, when agents perform high-risk operations, existing managed execution solutions mostly remain at the macro-level governance of workflow. Untrusted external content returned by tools is often directly shared with the agent's subsequent inference context, making it easy for these external contents to cause intent drift or unauthorized operations, or even change the approved execution boundaries. In addition, existing execution mechanisms usually do not introduce verification constraints for pre-declared boundaries at the actual interception points of tool calls, and it is difficult to formally reconcile the agent's pre-declared planned actions with the actual read and write side effects after execution. As a result, it is difficult for agents to form structured control boundaries when executing with multiple tools and in multiple rounds, and there is a lack of a unified execution evidence recording and verification mechanism. Consequently, existing agent systems have low security closed-loop management capabilities and low operational controllability when performing high-risk operations in practical applications. Summary of the Invention
[0004] This application provides an operation control method, device, electronic device, and storage medium for an intelligent agent, which can solve the above-mentioned technical problems.
[0005] To achieve the above objectives, a first aspect of this application proposes an operation control method for an intelligent agent. The method is applied to a tool call interception layer of a computer device, the tool call interception layer operating between the inference layer and the downstream resource layer of the intelligent agent. The method includes: In response to the candidate tool invocation request generated by the agent, obtain the current execution boundary associated with the candidate tool invocation request; The legality of the candidate tool invocation request is verified based on the current execution boundary to obtain the request legality result; When the validity result of the request indicates that the candidate tool call request has passed the verification, the operation corresponding to the candidate tool call request is executed to generate an actual execution record, and the external return content generated by the execution operation is stored in a preset isolated storage area; Based on the current execution boundary and the actual execution record, the actual execution side effects of the candidate tool invocation request are determined item by item to obtain the determination analysis results; Based on the judgment and analysis results, the operation state of the intelligent agent is transferred and controlled.
[0006] In some embodiments, the step of validating the candidate tool invocation request based on the current execution boundary to obtain a request validity result includes: Based on the current execution boundary, the protected fields are extracted, and the digest is calculated based on the field value of the protected fields to obtain the real-time digest value. The real-time summary value is compared with the pre-stored baseline summary value to obtain the consistency comparison result; When the consistency comparison result indicates that the real-time summary value is consistent with the benchmark summary value, multi-dimensional running attributes are extracted based on the candidate tool call request, and the multi-dimensional running attributes are compared with the pre-stored valid authorization decisions to determine the coverage result. When the coverage determination result indicates that the valid authorization decision covers the multi-dimensional running attributes, a request legitimacy result indicating that the candidate tool call request has passed the verification is generated.
[0007] In some embodiments, the step of performing digest calculation based on the field value of the protected field to obtain a real-time digest value includes: Obtain the serialization version identifier of the current execution boundary, and rearrange the object key name of the protected field based on the preset character encoding rules to obtain a normalized byte sequence; The serialization version identifier, the set of names of the protected fields, and the normalized byte sequence are concatenated to obtain concatenated data. The concatenated data is then input into a preset cryptographic hash function for one-way hash calculation to obtain the real-time digest value.
[0008] In some embodiments, the multidimensional runtime attributes include a tool identifier, action type, resource access set, and current timestamp. The step of performing an overwrite determination by comparing the multidimensional runtime attributes with pre-stored valid authorization decisions to obtain an overwrite determination result includes: Obtain an authorization decision with an expiration date later than the current timestamp, and use it as the valid authorization decision; When the effective authorization decision includes the multidimensional operational attribute in multiple attribute dimensions, a coverage determination result is generated that represents the effective authorization decision covering the multidimensional operational attribute.
[0009] In some embodiments, storing the external return content generated by the operation into a preset isolated storage area includes: Maintain write isolation between the isolated storage area and the contract storage area that stores the current execution boundary; The external returned content in the isolated storage area is subjected to compliance verification, and after the compliance verification is passed, the external returned content is used as revision input to generate a new version candidate boundary; Replace the current execution boundary with the new version candidate boundary.
[0010] In some embodiments, the step of determining the actual execution side effects of the candidate tool invocation request item by item based on the current execution boundary and the actual execution record to obtain the determination analysis result includes: Based on the current execution boundary, the planned action is obtained through parsing. The planned actions are compared with the actual execution records to obtain the feature comparison results. When the feature comparison result indicates that there is a call identifier associated with the planned action in the actual execution record, and the actual call type in the actual execution record is consistent with the planned action, and the actual resource access set in the actual execution record does not exceed the authorized scope of the planned action, and the actual execution result in the actual execution record meets the success criteria of the planned action, the judgment analysis result indicating that the reconciliation has passed is generated.
[0011] In some embodiments, the step of performing migration control on the operational state of the agent based on the determination analysis result includes: When the judgment analysis result indicates that the actual execution record exceeds the authorized scope, or the actual call type in the actual execution record is inconsistent with the planned action, a reconciliation failure result is generated; Based on the reconciliation failure result, the operating state of the intelligent agent is restricted to either the rejection state or the manual upgrade handling state.
[0012] In some embodiments, before obtaining the current execution boundary associated with the candidate tool invocation request in response to the candidate tool invocation request generated by the agent, the method further includes: Obtain the request context of the candidate tool call request, and perform a hit judgment on the request context based on the trigger control rules to obtain the hit judgment result; When the hit determination result indicates that the request context hits the trigger control rule, and there is a new control policy that needs to be implemented, the session identifier to which the candidate tool call request belongs is determined; The session identifier is hashed and moduloed to obtain the corresponding bucket value; When the value of the bucket is within the preset grayscale effective range, the new control strategy is applied to the candidate tool call request; When the proportion of reconciliation failures during the policy operation exceeds a preset safety threshold, the gray-scale effective range is reset to control the system to revert to the state of applying the old control policy.
[0013] To achieve the above objectives, a second aspect of this application provides an operation control device for an intelligent agent. The device is applied to a tool call interception layer of a computer device, the tool call interception layer operating between the inference layer and the downstream resource layer of the intelligent agent. The device includes: A response module is used to respond to a candidate tool invocation request generated by the agent and obtain the current execution boundary associated with the candidate tool invocation request; The legality verification module is used to verify the legality of the candidate tool call request based on the current execution boundary, and obtain the legality result of the request; The execution module is used to execute the operation corresponding to the candidate tool call request when the request validity result indicates that the candidate tool call request has passed the verification, so as to generate an actual execution record and store the external return content generated by the execution operation into a preset isolated storage area; The side effect determination module is used to determine the actual execution side effects of the candidate tool call request item by item based on the current execution boundary and the actual execution record, and obtain the determination analysis results; The state transition control module is used to perform transition control on the operating state of the intelligent agent based on the judgment analysis results.
[0014] To achieve the above objectives, a third aspect of this application provides an electronic device, which includes a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the operation control method of the intelligent agent as described in the first aspect.
[0015] To achieve the above objectives, a fourth aspect of the present application provides a storage medium, which is a computer-readable storage medium storing a computer program that, when executed by a processor, implements the operation control method of the intelligent agent as described in the first aspect.
[0016] The operation control method, apparatus, electronic device, and storage medium for intelligent agents proposed in this application are applied to the tool call interception layer of a computer device. The tool call interception layer runs between the inference layer and the downstream resource layer of the intelligent agent. The method includes: First, in response to a candidate tool call request generated by the intelligent agent, obtaining the current execution boundary associated with the candidate tool call request; then, performing a legality check on the candidate tool call request based on the current execution boundary to obtain a request legality result; next, when the request legality result indicates that the candidate tool call request has passed the verification, executing the operation corresponding to the candidate tool call request to generate an actual execution record, and storing the external return content generated by the execution operation in a preset isolated storage area; next, based on the current execution boundary and the actual execution record, judging the actual execution side effects of the candidate tool call request item by item to obtain a judgment analysis result; finally, based on the judgment analysis result, performing migration control on the running state of the intelligent agent. This application embodiment, through a tool call interception layer between the agent's inference layer and the downstream resource layer, performs pre-validation of candidate tool call requests based on the current execution boundary, and stores the generated external return content in a preset isolated storage area after execution. This prevents untrusted external content from directly modifying the fixed execution boundary and control flow, effectively reducing the risk of intent drift or unauthorized operation by the agent due to tool return content. Furthermore, by judging the actual execution side effects item by item based on the current execution boundary and actual execution records and implementing state transition control, a machine-determinable formal reconciliation of the agent's pre-declared planned actions and the actual read / write side effects is achieved. This avoids judging task completion solely based on the agent's subjective declaration. Thus, without reconstructing the agent's original inference and action loop, a structured security control boundary is established for the agent when executing multiple tools and in multiple rounds, improving the agent system's security closed-loop governance capability and operational controllability when performing high-risk operations.
[0017] Other features and advantages of this application will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the application. The objectives and other advantages of this application may be realized and obtained by means of the structures particularly pointed out in the description, claims and drawings.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0035] It should be noted that although functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart.
[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.
[0037] With the development of large language model agents, agent systems are now able to invoke external tools and execute multi-step tasks driven by user intent, such as reading or writing files, running system commands, accessing databases, calling external interfaces, and operating browsers. Existing agent execution modes mainly include reactive execution mode and post-planned execution mode, which improve the flexibility and predictability of multi-step tasks to a certain extent.
[0038] Specifically, reactive execution typically employs a "reasoning-action-observation" cyclical mechanism, where the agent generates reasoning content and selects tool actions at each step based on the current context. While this approach is suitable for exploratory tasks, the lack of a complete pre-execution plan constraint makes the agent prone to deviating from its original intent in complex, multi-step tasks. Furthermore, multi-tool, multi-round execution often lacks structured boundaries, making it difficult to clearly determine which resources will be read or written, and the execution trajectory is often in the form of unstructured text or logs, making it difficult to use for post-event auditing and unified verification.
[0039] On the other hand, the post-planning execution model generates a list of steps in advance for execution scheduling before the task begins. While this improves the integrity of the control flow, the generated plan typically only describes the task steps and usually does not include key governance elements such as read / write resource boundaries, risk levels, approval requirements, and rollback plans. Furthermore, during the actual execution phase, it is difficult to establish a verifiable link between the tool's returned results and the pre-approval records and the established plan. This results in a lack of a unified execution evidence package and validator system after the plan is completed, and there is a lack of standardized paths for revision, upgrades, or rollbacks after verification failures.
[0040] To address these shortcomings, some existing managed execution solutions attempt to introduce governance primitives such as execution contracts, approval records, and evidence packages at the workflow level. However, when agents perform high-risk operations, these macro-level governance solutions still have significant limitations: execution contracts lack standardized sealing of protected fields and pre-call recalculation verification after approval, making it difficult to prevent arbitrary paths during runtime from modifying approved boundaries; existing approval mechanisms typically only prove the existence of approval, without conducting runtime coverage checks on multiple dimensions such as tool name, action type, risk level, and read / write sets at tool call interception points; untrusted external content returned by tools is often directly shared with the agent's subsequent inference context, lacking a trusted isolation path, making these external contents highly susceptible to causing agent intent drift or unauthorized operations, and even altering approved execution boundaries.
[0041] Furthermore, existing execution mechanisms typically fail to extend security verification constraints to the actual interception points where tool calls are issued. After execution, existing verification methods often remain at the surface level, merely checking whether the action has been completed. They struggle to formally reconcile the agent's pre-declared planned actions with the actual read / write side effects in terms of existence, type consistency, read / write set inclusion, and expected result fulfillment.
[0042] Therefore, existing intelligent agent systems struggle to form structured control boundaries when executing multiple tools and rounds, lacking a unified mechanism for recording execution evidence and verifying closed loops. This results in existing intelligent agent systems having low safety closed-loop management capabilities and operational controllability when performing high-risk operations in practical applications.
[0043] Based on this, the embodiments of this application perform pre-validation of candidate tool call requests based on the current execution boundary through a tool call interception layer between the agent's inference layer and the downstream resource layer. After execution, the generated external return content is stored in a preset isolated storage area, so that untrusted external content cannot directly modify the fixed execution boundary and control flow, effectively reducing the risk of the agent's intent drift or unauthorized operation caused by the tool return content. Furthermore, by judging the actual execution side effects item by item based on the current execution boundary and the actual execution record and implementing state transition control, a machine-determinable formal reconciliation of the agent's pre-declared planned actions and the actual read and write side effects is realized. This avoids the situation where task completion is judged solely based on the agent's subjective declaration. Thus, without reconstructing the agent's original inference and action loop, a structured security control boundary is established for the agent when executing multiple tools and in multiple rounds, improving the agent system's security closed-loop governance capability and operational controllability when performing high-risk operations.
[0044] The operation control method, apparatus, electronic device and storage medium of the intelligent agent provided in the embodiments of this application will be further described below.
[0045] In some embodiments, to implement the above-described operation control method for intelligent agents, this application provides a managed execution system for high-risk operations of intelligent agents. It should be noted that, based on the aforementioned technical architecture, the overall system deployment (or its core control logic) of this application embodiment is based on the tool call interception layer of the computer device, and the tool call interception layer runs between the inference layer of the intelligent agent and the downstream resource layer. By constructing this runtime mandatory control checkpoint between the intent generation node of the intelligent agent (such as a large language model) and the execution node that actually reaches the underlying operating system resources (such as file systems, databases, external networks, etc.), the system can physically or logically intercept and take over high-risk tool call requests without intruding on the original inference logic of the intelligent agent.
[0046] Specifically, to implement a managed closed-loop governance process of "pre-planning - in-process execution - post-verification" in the tool invocation interception layer, the system of the present invention may include the following modules: Intent classification module: used to receive user requests, agent plans, or tool invocation requests, and identify operation categories, tool risk levels, resource sensitivity, and workflow complexity; Contract generation module: used to generate managed execution contracts when triggering conditions are met; Approval governance module: used to trigger manual or automatic approval based on risk levels and approval strategies, and record governance decisions; Controlled execution module: used to execute tool invocations according to the planned actions, tool scope, and resource boundaries defined in the contract; Evidence package generation module: used to collect tool results, inspection records, risks, hypotheses, untested areas, and manual review records; Verification module: used to run one or more verifiers and output pass, warning, or failure results; Disposal decision module: used to generate acceptance, revision, upgrade, or rollback disposal based on the verification results; Shared state module: used to record participants, actions, read / write sets, version dependencies, hypotheses, and conflicts in multi-agent collaboration scenarios; Governance evolution proposal module: used to generate governance improvement proposals with review priorities based on running events, failure modes, and evidence.
[0047] The operation control method for intelligent agents provided in this application can be applied to the tool call interception layer in any computer device with computing resources (such as servers, smart terminals, computing processors, etc.). The tool call interception layer runs between the inference layer (large language model generates tool call intent) of the intelligent agent and the downstream resource layer (file system, process, network, browser, database, etc.).
[0048] The following describes several feasible implementations of the operation control method for the real-time intelligent agent of this application.
[0049] In one embodiment, each original tool is wrapped as a proxy function and then registered in the tool registry of the intelligent agent framework (such as LangChain Tools, OpenAIFunction Calling, Microsoft Semantic Kernel Plugins, AutoGen Function Tools, etc.). The original tool is not directly exposed to the inference layer; all candidate calls are forwarded through the proxy function. Before the call, the proxy function executes mechanism A (sealing and recalculating), mechanism B (multi-dimensional authorization overlay), and mechanism C (isolation and flow differentiation), and after judgment, delegates the execution to the original tool; after execution, the proxy function writes the tool's return result into the isolation repository or evidence set according to its source attribute. The advantage of this approach is low intrusion into the host framework and no modification to the framework's core code is required.
[0050] In another embodiment, within an agent framework that supports middleware chains (such as AutoGen's callback handler, LangChain's RunnableConfig callbacks, and OpenAI Agents SDK's lifecycle hooks), three phases of hooks are registered: (a) `on_tool_call_start` executes mechanisms A and B; (b) `on_tool_call_end` executes external content offloading and writing to the isolated repository; and (c) `on_session_end` or a periodic hook triggers a five-element item-by-item reconciliation and disposal decision. The advantage of this approach is that it can uniformly process all tools without rewriting the tool registry and is aligned with the host framework's lifecycle.
[0051] In another embodiment, an out-of-process gateway or proxy (such as a local HTTP proxy, gRPC sidecar, Unix domain socket daemon, file system FUSE layer, or database connection pool proxy) is placed before the tool actually accesses operating system resources. The agent process accesses downstream resources through this gateway, which performs the determination and recording of mechanisms A, B, and C before and after forwarding. The advantage of this approach is complete decoupling from the agent framework, allowing for the simultaneous management of multiple agent instances or multi-language hybrid stacks; the disadvantage is higher deployment complexity, making it suitable for enterprise-level production environments.
[0052] It is understandable that, regardless of the implementation method, the summary recalculation of Mechanism A must occur before the parameters of the candidate tool call are bound but before they reach downstream resources; the coverage determination of Mechanism B must occur after Mechanism A and before the execution parameters of Mechanism C are generated; and the isolation and diversion of Mechanism C must occur before the tool's returned content enters the subsequent inference context. These three mechanisms are executed sequentially on the same interception event sequence, constituting the same runtime interception path as described in Linkage Clause D.
[0053] The observation of the actual read / write resource set is recorded separately by the observation paths corresponding to each tool type: file-type tools are recorded by file wrappers for the normalized paths of being opened / read / written / renamed / deleted; shell-type tools are recorded by command execution sandboxes or file system monitors for the files, environment variables, network endpoints, and exit states actually accessed by the process; browser-type tools are recorded by browser driver layers (such as Playwright / Puppeteer hooks) for DOM reading, form submission, downloading, uploading, clipboard, and navigation events; database-type tools are recorded by database proxies or SDK wrappers for database tables, primary key ranges, statement types, and transaction boundaries; and external API-type tools are recorded by gateways, HTTP proxies, or SDK wrappers for request methods, normalized endpoints, identity contexts, and response states. Tool calls that cannot be covered by the above observation paths are marked as incomplete observations, and their verification results are at most a warning level, escalating to failure when write side effects are involved.
[0054] Reference Figure 1 This is an optional flowchart of the operation control method for an intelligent agent provided in the embodiments of this application. Figure 1 The method may include, but is not limited to, steps 101 to 105. It is also understood that this embodiment... Figure 1 The order of steps 101 to 105 is not specifically limited. The order of steps can be adjusted or some steps can be reduced or added according to actual needs.
[0055] Step 101: In response to the candidate tool invocation request generated by the agent, obtain the current execution boundary associated with the candidate tool invocation request.
[0056] Step 101 will be described in detail below.
[0057] In step 101 of some embodiments, when responding to a candidate tool call request generated by the agent, the current execution boundary associated with the candidate tool call request is first obtained. When processing a workflow, the agent generates the intention to call underlying operating system resources based on a "reasoning-action" loop. At the interception point where the parameters of the candidate tool call request have been generated and bound, but before it crosses the execution gateway to reach downstream resources, the agent captures the candidate tool call request. Subsequently, the current execution boundary C corresponding to the candidate tool call request is extracted. This current execution boundary C externalizes and structures the operation plan originally implicit in the agent's unrestricted free reasoning text. It internally records the resource access scope and compliance rules upon which the action relies, thus providing an immutable preliminary basis for subsequent interception control and permission comparison.
[0058] Among them, the candidate tool call request refers to the instruction action generated by the agent (such as a large language model) during the inference process to call external underlying tools (such as file reading, system command execution, network request, etc.). At this time, the relevant parameters of the request have been bound, but have not yet substantially reached the downstream operating system resources; the current execution boundary refers to the structured boundary declaration (i.e., the managed execution contract C) generated in advance before the task is executed, which is used to clearly define the set of actions that the agent plans to execute, the range of read and write resources that are allowed to be accessed, the risk level and other protected specification information.
[0059] Reference Figure 2 Before obtaining the current execution boundary associated with the candidate tool invocation request in response to the candidate tool invocation request generated by the agent, the method further includes steps 201 to 205.
[0060] Step 201: Obtain the request context of the candidate tool call request, and perform a hit judgment on the request context based on the trigger control rules to obtain the hit judgment result.
[0061] Step 202: When the hit judgment result indicates that the request context has triggered the control rule, and there is a new control policy that is yet to take effect, determine the session identifier to which the candidate tool call request belongs.
[0062] Step 203: Hash the session identifier and take the modulo to obtain the corresponding bucket value.
[0063] Step 204: When the bucket value is within the preset grayscale effective range, apply the new control strategy to the candidate tool call request.
[0064] Step 205: When the proportion of reconciliation failures during the policy operation exceeds the preset safety threshold, reset the grayscale effective range to control the system to fall back to the state of applying the old control policy.
[0065] Steps 201 to 205 are described in detail below.
[0066] In step 201 of some embodiments, after the agent generates the operation intent, it extracts the environmental information and parameter features of the current call to form a request context for the candidate tool call request. This request context is then input into a pre-configured rule engine to perform a hit judgment based on trigger control rules, obtaining a hit judgment result. It is understood that the hit judgment process aims to identify whether the risk level or business complexity of the current call reaches a threshold requiring strict control. Specifically, this includes: whether the tool has write capabilities; whether the tool executes shell or system commands; whether the tool accesses a browser or submits a web form; whether the tool calls an external API; whether the tool call involves databases, file systems, production services, or sensitive data; whether a single model response includes multiple tool calls; whether the operation originates from a public channel, group chat, webhook, or untrusted trigger source; and whether the operation belongs to high-risk processes such as industrial operations, financial transactions, or deployment. The system can define which operation categories require contracts through the `contractRequiredFor` configuration item and which risk levels require approval through the `requireApprovalForRisk` configuration item. This hit detection allows for the differentiation between routine low-risk and high-risk operations, yielding a hit detection result that indicates whether a managed execution process needs to be initiated. This avoids unnecessary computational overhead caused by implementing high-intensity control over all operations.
[0067] In some embodiments, when an agent's operation request meets preset managed conditions, the contract generation module automatically creates a managed execution contract. This managed execution contract serves as the standard for agent operations and includes at least multiple dimensions such as work objectives, user request summaries, planned actions, read / write resource sets, tool requirements, risk levels, approval requirements, assumptions, verification plans, rollback plans, and success criteria. The key technical value of this managed execution contract generation lies in its ability to externalize the previously vague plan, implicit in the free-flowing reasoning text of a large language model, into a highly structured, pre-declared execution boundary. This externalization allows both the operator and the underlying system interception components to perform precise and deterministic checks on the agent's plan content before high-risk tool calls are actually issued.
[0068] To completely prevent untrusted external inputs from altering the established execution boundaries, in a preferred embodiment, the contract generation module calculates a contract digest value (e.g., an instance field named `approvedDigest`) for a pre-defined set of protected fields when the managed execution contract receives approval authorization. Specifically, the system marks core constraint fields such as the planned action set, read resource set, write resource set, risk level, approval requirements, verification plan, rollback plan, and success criteria as protected and not automatically modifiable by the agent. During subsequent execution, if received external input content (such as parsed webpage text, API return results, etc.) contains prompts attempting to expand the write scope, lower the risk level, skip approval steps, or change success criteria, the system strictly restricts the permissions of that external input content. Such external content can only be written as a trusted payload (e.g., an instance field named `untrustedToolOutputs`) into the isolated execution evidence set, and is absolutely prohibited from directly modifying the authorized managed execution contract in situ.
[0069] In one embodiment, to ensure high accuracy and cross-platform consistency of anti-tampering verification, the contract digest value generation and runtime recalculation verification of the protected field set adopt a mechanism that includes a specific initialization algorithm and deterministic serialization rules.
[0070] During the sealing phase of authorization initialization, the system first extracts the protected field set F. Then, using a normalized serialization function (e.g., canonicalize), F is recursively sorted and fixedly encoded to output a flat, normalized byte sequence, bytes. Next, the system concatenates the field set F with the serialized bytes and inputs it into a cryptographic hash function (e.g., SHA-256) to calculate the final sealed digest value, seal. Finally, the contract identifier, the field set F, and the digest value seal are securely stored.
[0071] To ensure that the same logical boundaries generate completely consistent byte sequences and digest values across different implementation languages, inter-process communication, and deployment models, the aforementioned normalized serialization function must strictly adhere to the following set of ten deterministic rules (which are logically equivalent to the RFC 8785 standard and have been extended to accommodate intelligent agent scenarios): Field name sorting rules: The key names of data objects must be strictly rearranged in ascending order according to Unicode code points; and duplicate key names are strictly prohibited within the same object. Once a duplicate is detected, serialization will fail immediately and the current data sealing will be terminated.
[0072] Character encoding rules: All strings must be uniformly and forcibly encoded in UTF-8 for output; before serialization, all strings must be processed by Unicode standard combination normalization (NFC) to completely eliminate byte differences caused by visually identical but different underlying code unit character combinations (such as single code points and combined characters).
[0073] Number normalization rules: For integer types, the shortest decimal representation is used, and all leading zeros and positive prefixes except for a single zero are removed; for floating-point types, the shortest round-trip representation without trailing zeros is used, and the exponent sign is standardized to uppercase letters. Furthermore, the literals of Not-Number (NaN) and Infinity (±Infinity) are strictly prohibited from appearing in protected fields.
[0074] Boolean and null value distinction rules: Boolean values are always output in their standard form; null values are always output in their corresponding standard null literals; and in the underlying serialized byte stream, these basic literals must be strictly distinguished from strings with the same spelling through type tags to prevent cross-type obfuscation injection.
[0075] Array order and set rearrangement rules: For regular arrays, maintain their original declaration order; however, when the business semantics of the protected field are detected as "unordered set" (e.g., read resource set, write resource set), the system must first rearrange the elements in the set according to their normalized byte order before outputting them, thereby eliminating false positive tampering alarms caused by different registration orders; at the same time, field names with set semantics must be explicitly listed in the whitelist in the system configuration, and dynamic expansion by the agent is strictly prohibited.
[0076] Empty state differentiation rules: For the five different empty states of null value, empty string, empty array, empty object, and missing field key name, the serialization output must have clear differentiation, and any implementation is strictly prohibited from merging them into the same byte sequence.
[0077] No semantic whitespace removal rule: All no semantic whitespace characters (including spaces, tabs, newlines, etc.) must be removed from the final serialized byte stream, and no gaps should be left before or after the element separator and the key-value separator.
[0078] Nesting and circular reference constraints: The nesting depth of protected fields is limited to a preset security threshold (e.g., no more than 32 levels); and before serialization starts, the system must use a depth-first algorithm to detect circular references in the data structure, and terminate the operation immediately if a circular dependency is found.
[0079] Language-specific type rejection rule: The data structure of protected fields must not contain language-host specific types other than standard data types (such as date / time objects or large number objects in a specific programming language); if such data needs to be stored, it must be explicitly converted to a standard string or standard object before it is entered.
[0080] Algorithm version binding rule: The version identifier of the normalized serialization algorithm will serve as the core factor in digest calculation, and will be concatenated with the field set and the normalized byte sequence to generate the final hash value. This ensures that any undeclared implicit algorithm upgrade will be considered an illegal change to the field content by the system, thereby triggering boundary invalidation.
[0081] Furthermore, to address the engineering challenge of "security patches causing all contracts to be mistakenly invalidated" due to algorithm version binding, this embodiment introduces a four-tier governance process for algorithm upgrades. The version identifier can be defined as a tuple containing a list of major version numbers and compatible version numbers, as described below.
[0082] Pure byte sequence preservation fix: For performance optimizations or code refactoring that do not change the output, the new version number will be added to the compatibility list of the old version, existing contracts do not need to be invalidated, and the transition between the old and new versions is smooth.
[0083] Rule set compatibility extension: For upgrades that add new rules but do not affect existing outputs, the new version number will not be included in the compatibility list. Existing contracts will continue to use the old version for verification, while new contracts will use the new version for verification.
[0084] Incompatible upgrades: When the core sorting or coding rules change, existing contracts will be forced into an invalid state and must go through a revision process to regenerate the summary and undergo manual approval again.
[0085] Emergency Security Upgrade: When a critical vulnerability such as hash collision is disclosed in an older version, the system triggers a downgrade strategy, immediately invalidating and cutting off all contracts that depend on the older version, while clearing the compromised compatibility list and forcing an upgrade and replacement.
[0086] Based on the ten deterministic rules and algorithmic governance mechanisms mentioned above, the system performs pre-call verification (e.g., the `sealCheck` function) each time a tool call request is captured. The system extracts the currently protected field according to the same rules and recalculates the real-time digest value `seal'`, then compares it with the pre-stored baseline digest value. Regarding state machine transitions, if the verification passes (true), the process proceeds to the next interception stage; if the verification fails (false), the managed execution contract state is forcibly transitioned to an invalidated state, and all subsequent tool calls attempting to use the contract are rejected. Through this mechanism, the security of the agent's runtime control flow is ensured, provided the observation path is complete and the cryptographic algorithm remains unbroken.
[0087] Therefore, in step 202 of some embodiments, after confirming that the current call needs to be controlled, it is further detected whether there is an updated version policy undergoing gray-scale verification in the background. Therefore, when the hit judgment result indicates that the request context hits the trigger control rule and there is a new control policy that is about to take effect, the session identifier to which the candidate tool call request belongs is determined. If it is currently in the verification period of the transition between the old and new policies, the session identifier to which the candidate tool call request is attached is extracted. The purpose of extracting the session identifier is to ensure the context stickiness of the routing, that is, to ensure that within the life cycle of the same agent processing the same multi-step task, multiple tool calls associated with it are all routed to the same control policy, preventing the execution state from being broken or the context from being inconsistent due to the policy switching in the middle of the session.
[0088] Among them, the new control strategy refers to the new version of the managed execution contract or governance rule generated during the system operation process to fix security vulnerabilities, optimize execution boundaries or adjust the scope of authorization, and which is in the stage of waiting for release testing.
[0089] In step 203 of some embodiments, the session identifier is hashed and moduloed to obtain the corresponding bucket value. To achieve stateless and deterministic traffic allocation, a preset hash function Hash() is used to hash the extracted session identifier S_{id}, and a preset bucket base N (e.g., N=10000) is used for modulo operation to obtain the bucket value B = Hash(S_{id}) mod N. Through this hash modulo operation, a massive number of requests with different session identifiers can be statistically evenly distributed across logical buckets from 0 to N-1, and the bucket value B calculated for the same session identifier remains constant at any given time.
[0090] The session identifier is an identifier (Session ID) used to uniquely identify the current multi-turn dialogue context or specific multi-step workflow of an agent, and is used to ensure the consistency of routing within the same business process.
[0091] In step 204 of some embodiments, when the bucketing value falls within the preset grayscale effective interval, a new control policy is applied to the candidate tool invocation request. The current grayscale effective interval is defined as [0, R_{target}), where R_{target} is the grayscale threshold set in the current phase, and 0 ≤ R_{target} ≤ N; next, it is determined whether the bucketing value B satisfies 0 ≤ B < R_{target}. When this condition is satisfied, that is, 0 ≤ B < R_{target}, it indicates that the current session is selected to participate in the verification of the new policy, and the new control policy (for example, stricter read-write resource boundary limits or new validator logic) is adopted to perform subsequent legality verification and reconciliation processes; if this condition is not satisfied, the old control policy that operates stably is continuously used, so that the activation proportion of the new control policy can be controlled by adjusting the value of R_{target}.
[0092] In step 205 of some embodiments, during the grayscale operation of the new control policy, the background continuously collects and monitors the judgment analysis results output in the managed execution process. When it is detected that the reconciliation failure proportion during the policy operation exceeds the preset safety threshold, the grayscale effective interval is reset, so that the system is controlled to roll back to the state where the old control policy is applied. Specifically, the reconciliation failure proportion P_{fail} is counted, which is the ratio of the number of reconciliation failures generated by requests falling into the grayscale interval to the total number of requests in this interval. When it is monitored that P_{fail} exceeds the preset safety threshold T_{safe} (for example, a large number of legitimate requests are blocked or out-of-bounds behaviors occur frequently due to incorrect new policy configuration), an automatic fuse mechanism is triggered to reset R_{target} in the above grayscale effective interval to 0, so that the hash modulo result of any subsequent session identifier cannot fall into this interval, thereby blocking the continued activation of the new control policy and forcing all requests to smoothly and automatically roll back to the stable state applying the old control policy.
[0093] The grayscale effective interval refers to a numerical range defined in the full buckets, and requests corresponding to the buckets falling within this range will be routed to the new control policy, which is used to verify the stability of the new control policy on the premise of controlling the risk blast radius.
[0094] Through steps 201 to 205 above, a session-consistent canary release and circuit breaker rollback mechanism is introduced in the pre-managed phase when the agent performs high-risk operations. This enables the security boundary policies or verification rules for the agent to be verified in the real workflow with an extremely controllable explosion radius when they are evolved and upgraded. Furthermore, by monitoring the underlying machine reconciliation failure indicators, automatic rollback without human intervention is achieved, which effectively reduces the risk of system-level failures caused by policy updates. This ensures the security of agent execution while improving the reliability of the dynamic evolution of governance rules.
[0095] Step 102: Perform a legality check on the candidate tool call request based on the current execution boundary to obtain the legality result of the request.
[0096] Step 102 is described in detail below.
[0097] In step 102 of some embodiments, the candidate tool call request is then validated based on the current execution boundary to obtain a validity result. Specifically, this validity validation process mainly checks whether the specific operational target pointed to by the candidate tool call request (e.g., the tool identifier to be called, the planned read / write resource path, etc.) is completely restricted within the current execution boundary C and the envelope allowed by the existing authorization decision. When the compliance conditions are verified, a validity result indicating that the request has passed the validation is output; if any resource over-boundary probing or permission mismatch is identified, a validation failure result is output, thereby forming a physical or logical hard block before the tool call is actually issued, as described below.
[0098] Reference Figure 3 The legality of candidate tool call requests is verified based on the current execution boundary to obtain the legality result of the request, including the following steps 301 to 304.
[0099] Step 301: Extract based on the current execution boundary to obtain the protected fields, and perform digest calculation based on the field values of the protected fields to obtain the real-time digest value.
[0100] Step 301 will be described in detail below.
[0101] In step 301 of some embodiments, protected fields are extracted based on the current execution boundary, and a digest is calculated based on the field values of the protected fields to obtain a real-time digest value. Specifically, to prevent the agent from being tampered with by untrusted external content during runtime, the integrity of the current execution boundary C needs to be pre-verified. First, the set of protected fields (Fprotected) involving security constraints is extracted from the current execution boundary C. Then, the field values of the protected fields are serialized according to preset deterministic normalization rules (e.g., ascending order of object key names using Unicode, normalization of specific characters, etc.) to eliminate interference caused by format differences in data structures during memory transfer. Based on this, the normalized byte stream is input into a preset one-way cryptographic hash function (e.g., SHA-256 algorithm) for hash calculation, thereby obtaining a real-time digest value (Hcurrent) that can uniquely and accurately represent the boundary data state at the current interception point.
[0102] Among them, protected fields refer to the core constraint clauses that are clearly recorded in the current execution boundary and are related to the security of system resources and execution compliance. These include pre-declared sets of planned actions, permitted resource read and write ranges, and risk statements. These fields are prohibited from being modified in place by untrusted external inputs during runtime.
[0103] The following section will describe in more detail how to determine the real-time summary value.
[0104] Reference Figure 4 The digest is calculated based on the field value of the protected field to obtain the real-time digest value, including the following steps 401 to 402.
[0105] Step 401: Obtain the serialization version identifier of the current execution boundary, and rearrange the object key names of the protected fields according to the preset character encoding rules to obtain a normalized byte sequence.
[0106] Step 402: Concatenate the serialization version identifier, the set of names of protected fields, and the normalized byte sequence to obtain concatenated data. Input the concatenated data into a preset cryptographic hash function for one-way hash calculation to obtain a real-time digest value.
[0107] Steps 401 to 402 are described in detail below.
[0108] In step 401 of some embodiments, during the preparation stage of anti-tampering verification of the current execution boundary at the interception point, it is necessary to convert the structured data at runtime into a flat byte stream for hash calculation, that is, to obtain the serialization version identifier of the current execution boundary, and to rearrange the object key name of the protected field based on the preset character encoding rules to obtain a normalized byte sequence. First, the pre-configured serialization version identifier (V_{serial}) is read to determine the applicable serialization strategy. Then, for the extracted protected field (F_{protected}), since it may appear as an unordered set of key-value pairs in memory or inter-process communication, direct hash calculation would result in logically equivalent but physically different data producing different digests. Therefore, a preset character encoding rule is executed, such as recursively rearranging all object keys within the protected field F_{protected} according to the ascending order of Unicode code points, and performing normalization processing on the strings within it. After deterministic serialization processing, the arbitrariness and ambiguity at the data representation level are eliminated, thereby transforming the protected field F_{protected} into a stable and unique normalized byte sequence (Seq_{norm}).
[0109] Among them, the serialization version identifier is an identifier used to indicate the serialization algorithm and normalization rule version used in the current digest calculation. Its purpose is to ensure backward compatibility when the algorithm is upgraded or changed, and to prevent compliant data from failing to verify when recalculating the digest due to changes in the underlying serialization rules. The character encoding rule is a preset constraint condition for converting structured data in memory into a deterministic byte stream. Since the key-value pair arrangement order of the same data object (such as a dictionary or JSON) in memory may be different, this rule eliminates this non-logical difference by specifying the rearrangement order of object key names and the normalization method of strings. The normalized byte sequence refers to the unique and deterministic underlying byte stream payload output after the memory data of the protected fields is processed strictly according to the above character encoding rules.
[0110] In step 402 of some embodiments, after obtaining the normalized byte sequence Seq_{norm}, to prevent shift attacks or field substitution attacks targeting the data structure, it is necessary to strongly bind the metadata and payload data. Therefore, the serialization version identifier, the set of names of protected fields, and the normalized byte sequence are concatenated to obtain concatenated data. The concatenated data is then input into a preset cryptographic hash function for one-way hash calculation to obtain a real-time digest value. Specifically, the set of names corresponding to the protected fields (Names(F_{protected})) is extracted, and the serialization version identifier V_{serial}$, the set of names Names(F_{protected}), and the normalized byte sequence Seq_{norm} are concatenated at the byte stream level according to a fixed format or delimiter to obtain complete concatenated data (Data_{concat}), i.e., Data_{concat} = V_{serial} || Names(F_{protected}) || Seq_{norm}, where || represents the byte concatenation operation. Finally, the concatenated data Data_{concat} is used as a single input parameter and fed into a preset one-way cryptographic hash function (Hash()) for irreversible hashing to calculate a real-time digest value that characterizes the current state of the protected field, i.e., H_{current} = Hash(Data_{concat}).
[0111] Among them, a cryptographic hash function refers to a one-way hash algorithm (such as the SHA-256 algorithm), which can map input data of arbitrary length to ciphertext output of fixed length, and has the resistance to collision and avalanche effects (that is, small changes in input data will lead to huge differences in output results).
[0112] Through steps 401 to 402 above, by introducing version identifiers and strict character encoding rearrangement rules, the uncertainty of hash calculation caused by differences in cross-language environments or memory states is effectively eliminated, ensuring that logically equivalent execution boundaries will inevitably generate completely consistent normalized byte sequences. At the same time, by concatenating and fusing version metadata, field names and underlying byte sequences and performing one-way hash calculations, a high-precision cryptographic criterion is provided for subsequent boundary consistency comparisons.
[0113] Step 302: Compare the real-time summary value with the pre-stored baseline summary value to obtain the consistency comparison result.
[0114] Step 303: When the consistency comparison result indicates that the real-time summary value is consistent with the baseline summary value, extract the multi-dimensional running attributes based on the candidate tool call request, and perform a coverage determination on the multi-dimensional running attributes and the pre-stored valid authorization decisions to obtain the coverage determination result.
[0115] Steps 302 to 303 are described in detail below.
[0116] In step 302 of some embodiments, after obtaining the real-time digest value, a consistency comparison is performed between the real-time digest value and the pre-stored baseline digest value to obtain a consistency comparison result. The baseline digest value (Hsealed) is the original hash value synchronously calculated and sealed by the tamper-proof background service before the current execution boundary is initially generated, approved, and issued. When a tool call is intercepted by the gateway, the pre-stored baseline digest value Hsealed in the secure storage area is extracted and strictly compared with the recalculated real-time digest value Hcurrent at the site. If the baseline digest value Hsealed is equal to the real-time digest value Hcurrent, a consistency comparison result indicating that the boundary maintains its original state and has not been illegally tampered with is output. If any hash value difference exists, it indicates that the current execution boundary has undergone untrusted changes during its flow to the current interception point. In this case, an inconsistent blocking result is output, and the execution boundary is directly set to an invalid state.
[0117] The baseline digest value is a hash value calculated using a cryptographic one-way hash algorithm based on the protected fields and securely stored when the execution boundary is initially generated and approved; the real-time digest value is a hash value obtained by recalculating the protected fields on-site using the same algorithm when a call request is intercepted during runtime.
[0118] In step 303 of some embodiments, when the consistency comparison result indicates that the real-time digest value matches the baseline digest value, multi-dimensional runtime attributes are extracted based on the candidate tool call request. These multi-dimensional runtime attributes are then compared with pre-stored valid authorization decisions to determine coverage, resulting in a coverage determination result. After confirming that the data integrity of the execution boundary has not been compromised, the runtime fine-grained permission verification phase begins. Specifically, first, the actual operation parameters to be executed are parsed from the intercepted candidate tool call request to form a multi-dimensional runtime attribute (Attrreq). Then, a pre-stored valid authorization decision (Authvalid) matching the execution boundary is retrieved. Within the multi-dimensional logical space, the multi-dimensional runtime attribute Attrreq and the permission scope defined by the valid authorization decision Authvalid are compared dimension by dimension for inclusion. This coverage determination requires that the candidate request does not breach the defense envelope established by the authorization decision in each individual attribute dimension, such as tool category, intended file path, or target database table.
[0119] Among them, effective authorization decision refers to the control policy envelope generated in the pre-approval stage, which is in a valid state and clearly permits a specific range of operations. It defines the upper limit of the legal boundary of the agent's operations.
[0120] Coverage determination: refers to the formal determination logic in a multi-dimensional attribute space that verifies whether the range of each attribute of the operation to be performed is strictly equivalent to or subordinate to (i.e. completely falls within) the scope of permission defined by the authorization decision.
[0121] Multidimensional runtime attributes refer to the context parameter vector extracted from the candidate tool call request that is about to be executed, which can characterize its runtime characteristics. They typically cover multiple mutually orthogonal dimensions such as tool identifier, action type, set of read and write resources to be accessed, and risk rating, such as tool name dimension, action type dimension, risk level dimension, set of read resources dimension, set of write resources dimension, source session dimension, source channel dimension, and judgment timestamp dimension.
[0122] Each of the eight attribute dimensions corresponds to an independent type of privilege escalation attack surface. The dimensions are orthogonal to each other and cannot be substituted for one another. The absence of any dimension will expose the corresponding security blind spot, and this blind spot cannot be effectively covered by other dimensions.
[0123] Specifically, at the operational attributes and semantic levels: the protection objective of the tool name dimension is to prevent the malicious reuse of a single authorization across tools. For example, it can effectively prevent an agent from using the authorization of a read tool to illegally call a write tool to perform a write action. The action type dimension aims to prevent semantic substitution that uses read as a cover for writing. For example, it can prevent the submission and execution of operations that actually include underlying write side effects by using a regular read action type such as "file_read" as a cover. The risk level dimension is used to prevent privilege escalation behavior that uses low-risk approval to execute high-risk operations. For example, it can prevent the use of medium-risk level approval credentials to perform critical-risk level production environment deployment operations without authorization.
[0124] At the resource access boundary level: the core objective of the read resource set dimension is to prevent confidentiality boundary overflow, for example, preventing an agent that is only authorized to read ordinary document directories (such as docs / ) but actually reads sensitive key files of the system (such as secrets / prod.key) during operation. Conversely, the write resource set dimension is used to strictly prevent integrity boundary overflow, for example, preventing an agent that is only authorized to write to the draft directory (such as docs / draft / ) but actually tampers with core configuration files (such as config / prod.json). The separation and independent verification of the read and write dimensions ensure that data visibility and tamper resistance are doubly guaranteed.
[0125] At the execution context and timeliness level: the source session dimension aims to prevent cross-session approval replay attacks, such as preventing malicious reuse of authorized or expired approval credentials in session A and forced execution in an unrelated session B; the source channel dimension is used to prevent public or untrusted trigger sources (such as webhooks) from being used for high-risk operations, such as blocking operations triggered from public group chats to impersonate approvals in private secure channels to execute system deployments; in addition, the determination timestamp dimension can effectively prevent expired decisions from being "revived" due to malicious rollback of the system clock, ensuring that the timeliness verification of any operation is always valid.
[0126] Multidimensional operational attributes comprehensively cover the entire dimensional space of managed execution authorization decisions, from "operation object," "action nature," "scope of impact," and "source context" to "lifecycle duration." These dimensions target different security attributes (such as confidentiality, integrity, non-repudiation, and timeliness), and their collaborative verification mechanism ensures that when an agent invokes execution tools, it is subject to a strict and inescapable compliance envelope constraint, thereby significantly improving the system's defense depth against various complex unauthorized access scenarios.
[0127] Reference Figure 5The multidimensional runtime attributes include tool identifier, action type, resource access set and current timestamp. The multidimensional runtime attributes are compared with the pre-stored valid authorization decisions to determine the coverage, and the coverage determination result is obtained, including the following steps 501 to 502.
[0128] Step 501: Obtain authorization decisions with expiration dates later than the current timestamp, and use them as valid authorization decisions.
[0129] Step 502: When a valid authorization decision contains multidimensional operational attributes across multiple attribute dimensions, generate a coverage determination result representing the coverage of multidimensional operational attributes by the valid authorization decision.
[0130] Steps 501 to 502 are described in detail below.
[0131] In step 501 of some embodiments, authorization decisions with expiration dates later than the current timestamp are obtained as valid authorization decisions. Before implementing multi-dimensional permission verification, the pre-stored authorization decisions need to be filtered for timeliness. Specifically, the current timestamp (tcurrent) carried in the candidate tool call request is extracted, and the set of pre-stored authorization decisions for the current execution boundary is traversed. For each authorization decision, the expiration time threshold (texpire) recorded in its metadata is read. Through the time dimension comparison operator, authorization records that meet the condition texpire>tcurrent are filtered out. The set of authorization decisions that have not expired and still have legal validity at the current interception time is extracted as the benchmark for subsequent multi-dimensional attribute comparison, i.e., valid authorization decisions, to prevent the agent from using historically inherited, expired, stale authorizations (i.e., "replay attacks" or stale authorizations) to execute the current tool call.
[0132] In step 502 of some embodiments, after obtaining a valid authorization decision within its validity period, a multi-dimensional spatial inclusion determination logic is entered. When the valid authorization decision contains multi-dimensional operational attributes in multiple attribute dimensions, a coverage determination result representing the valid authorization decision covering the multi-dimensional operational attributes is generated. In this application's solution, the extracted multi-dimensional operational attributes are the request vector Attrreq={attrtool, attraction, attrres, ...}, and the permission envelope of a single valid authorization decision is the authorization vector Authvalid={authtool, authaction, authres, ...}. During the determination process, a logical conjunction operation is performed on each dimension in sequence, that is, the tool identifier is required to match the action type, and the resource access set requested must be a subset of the authorized resource access set (i.e., attrres). The authres) indicates that the candidate tool call request is fully within the pre-approved security defenses if and only if the valid authorization decision simultaneously satisfies the inclusion relationship across multiple defined attribute dimensions. In this case, the output represents the successful coverage determination; if the inclusion condition is not met on any single dimension (e.g., attempting to access a sensitive file path outside the authorization list), the coverage is deemed to have failed, thus blocking the call.
[0133] Through steps 501 to 502 above, the risk of expired authorization is eliminated by timestamp verification, and the authorization decision is required to include candidate tool call requests in all security dimensions such as tool category, action, and resource scope. This overcomes the privilege escalation vulnerability and resource over-boundary access problem that is easily caused by traditional single-dimensional (such as only verifying the tool name) authentication. Without increasing business intrusion, it significantly improves the security defense depth and access control accuracy of the intelligent agent operation control system during operation.
[0134] In some embodiments, the system uses an approval governance module to perform pre-emptive access control on managed execution contracts. Specifically, the approval governance module dynamically determines whether the current operation needs to trigger an approval flow based on the risk level declared in the contract (e.g., instance field name riskLevel) and approval requirements (e.g., instance field name approvalRequired). For operations marked as high-risk or extremely high-risk, the system mandates human intervention for approval. When approval is granted, the internal state of the managed execution contract will safely transition from "pending approval" to "approved"; conversely, if approval is rejected, the control flow directly enters the escalation or termination state. To form a traceable governance chain, all the above approval results are forcibly written into the underlying decision ledger, which immutably records the approver's identity, approval timestamp, approval reason, scope of authorization, and associated operation objects.
[0135] Furthermore, to adhere to the principle of least privilege, the approval governance module explicitly does not default any single approval to a global, broad authorization. In the preferred embodiment of this application, the scope of the approval decision is strictly limited, encompassing at least multiple dimensions such as the managed execution contract identifier (or its digest value), tool name, action type, risk level, set of read / write resources, source session, source channel, and validity period. When subsequent tool actions are actually issued, if the tool name, action type, risk level, or the set of resources attempted to be accessed exceeds the envelope defined by the single approval, the system's approval scope validator will immediately determine that the approval scope does not match and output an interception and failure result.
[0136] In a further preferred embodiment, to efficiently and securely perform multi-dimensional authorization coverage determination at the tool call interception point, a strict gating algorithm runs at the system's underlying layer. Specifically, the interception point abstracts the intercepted candidate actions into a feature octet a = (toolName, actionType, riskLevel, readSet, writeSet, sessionId, channelId, timestamp). Simultaneously, the system extracts a set of valid, active decisions D = {d_i} from the decision ledger, where each authorization decision d_i carries the corresponding permission coverage across the eight dimensions mentioned above.
[0137] During the coverage determination, the system iterates through each decision d_i in the decision set D for the input action a. This iteration logic employs a continuous multi-condition interception mechanism based on "rejection priority," as described below.
[0138] First, verify timeliness. If the expiration time of decision d_i is earlier than the action timestamp (considering system clock offset tolerance), then the decision is rejected. Second, verify the tool and action semantics in sequence. If the tool name of the candidate action is not within the set of tools allowed by the decision, or the action type is not within the set of action types allowed by the decision, then the decision is rejected. Third, verify risk and resource boundaries. If the risk level of the candidate action exceeds the highest risk level allowed by the decision, or if its actual read / write resource set (readSet and writeSet) is not completely contained within the read / write scope (readScope and writeScope) defined by the decision, then the decision is rejected. Finally, verify the context source. If the source session identifier or source channel of the candidate action is not within the scope defined by the decision, then the decision is also rejected.
[0139] The system generates an ALLOW result and allows passage to the subsequent interception point only if a decision d_i can successfully pass all eight dimensions of the above rigorous checks. If no single decision can completely cover the action after traversing the set D, the system generates a DENY result, blocks the call, and reports the uncovered attribute dimension as an overreach event payload for escalation.
[0140] Understandably, when determining the inclusion of resource paths (such as the `pathIncludes` logic), the system uses predefined path paradigms (e.g., glob matching or prefix matching) and prohibits the system from automatically extrapolating from a coarser authorization scope to sub-paths not explicitly listed. Before validation, the system enforces normalization of resource paths, including but not limited to relative path resolution, path separator normalization, symbolic link resolution, case sensitivity policy binding, and canonical form conversion for network addresses, database table names, browser DOM selectors, or external API endpoints. Any resource access request that fails normalization will directly lose its eligibility for coverage and be redirected to a rejection or escalation branch.
[0141] In the eight-dimensional coverage determination model constructed in this application embodiment, each attribute dimension corresponds to an independent and orthogonal overriding attack surface. The absence of any dimension will result in a blind spot in the corresponding security defense, and this blind spot cannot be compensated by other dimensions.
[0142] Specifically, the tool name dimension prevents malicious reuse of single authorizations across tools (e.g., using the authorization of the Read tool to call the Write tool); the action type dimension aims to prevent semantic substitution that uses read as a cover for write (e.g., using the file_read action as a cover to submit the actual write payload); the risk level dimension blocks privilege escalation behavior that uses low-risk approvals to execute high-risk operations; the read resource set dimension and the write resource set dimension respectively protect the confidentiality boundary and the integrity boundary, preventing cross-directory data theft and pollution; the source session dimension effectively resists cross-session approval replay attacks; the source channel dimension blocks unauthorized calls by public trigger sources (such as external webhooks) impersonating private channels with high privileges; and the judgment timestamp dimension prevents the "revival" vulnerability of expired decisions caused by system clock rollback.
[0143] Step 304: When the coverage determination result indicates that the effective authorization decision covers multi-dimensional operational attributes, generate a result indicating that the request legality of the candidate tool call request has passed the verification.
[0144] Step 304 will be described in detail below.
[0145] In step 304 of some embodiments, when the coverage determination result indicates that the valid authorization decision covers the multi-dimensional operational attributes, a request legitimacy result indicating that the candidate tool call request has passed the verification is generated. This is true if and only if each dimension parameter or range in the multi-dimensional operational attributes is completely contained within the permission space of the corresponding dimension in the valid authorization decision (i.e., logically satisfying Attrreq). When Authvalidation is triggered, the system determines that the current tool invocation behavior conforms to established security benchmarks. At this point, it generates a result indicating that the request has passed the authentication, serving as a deterministic execution credential to lift the current blockade and allow the candidate tool invocation request to access underlying resources. If any attribute is found to be out of bounds during the determination process (e.g., attempting to read a confidential file not listed in the authorization decision), the determination fails, the generation of a valid credential is refused, and subsequent operations are blocked.
[0146] Through steps 301 to 304 above, before the tool calls and actually reaches the underlying system resources, a strong consistency authentication mechanism is constructed that links "anti-tampering digest verification" with "multi-dimensional attribute authorization coverage". By comparing real-time hash recalculation with pre-stored data, potential attack paths that bypass security controls by injecting agent prompts are cut off. At the same time, through full-dimensional coverage judgment during runtime, it is ensured that the actual call parameters at the interception site are strictly limited to the pre-approved compliance envelope, bridging the trust gap between the agent's pre-static plan and the dynamic execution context, strengthening the security boundary of the managed execution path, and reducing the probability of unauthorized execution in high-risk operations.
[0147] Step 103: When the validity of the request indicates that the candidate tool call request has passed the verification, execute the operation corresponding to the candidate tool call request to generate an actual execution record, and store the external return content generated by the execution operation into a preset isolated storage area.
[0148] Step 103 will be described in detail below.
[0149] In step 103 of some embodiments, when the request legitimacy result indicates that the candidate tool call request has passed verification, the operation corresponding to the candidate tool call request is executed to generate an actual execution record, and the external return content generated by the execution operation is stored in a preset isolated storage area. After the request legitimacy result confirms that the current operation is compliant, the interception is lifted and the candidate tool call request is allowed to reach the corresponding downstream target tool for controlled actual execution. During the execution phase, the actual resource access and operation status are strictly collected through the underlying observation mechanism to generate the corresponding actual execution record E. At the same time, in the post-call data return phase, for the external return content generated by the execution operation, in order to prevent such potentially untrusted inputs (such as web page data encountering prompt injection attacks) from hijacking the control flow or tampering with the approved plan in the inference context of the subsequent intelligent agent, it is routed and written into the preset isolated storage area R_{iso}. The isolated storage area R_{iso} maintains a strict write unreachability constraint with the area storing the execution boundary, ensuring that external input data cannot directly modify the existing boundary rules before undergoing subsequent security trust verification.
[0150] External returned content refers to payload data (i.e., external entry content or content to be trusted) generated within the non-intelligent agent during or after the tool's execution, including but not limited to tool-returned text, web page content, external interface responses, or downstream model outputs, which have certain untrustworthy characteristics; the isolated storage area refers to an independent storage area (i.e., the external content repository Riso) used to receive and temporarily store the aforementioned external returned content during runtime, which is isolated from the storage area that saves the execution boundary in terms of code and memory execution path.
[0151] In some embodiments, once a candidate tool call request passes legitimacy verification and the managed execution contract is approved, the system's controlled execution module securely issues and executes the actual tool call according to a pre-declared set of planned actions. During execution, the system's underlying observation path continuously tracks and structurally records the actual tool call instances, return status, output summaries, error messages, resource access information, and key runtime events, thereby generating an irrefutable record of the actual execution.
[0152] It is understood that the controlled execution module provided in this application embodiment has good non-intrusiveness in its architectural design, and it does not require complete reconstruction or replacement of the agent's original "reasoning-action-observation" loop mechanism. Specifically, this module introduces a managed checkpoint at the interception point where the tool call reaches the target resource by wrapping the central tool call path. This allows the agent to be included in the constraints of the pre-declared execution boundary and fully retain the execution evidence record when executing high-risk tool calls, without changing the original reasoning architecture of the large language model.
[0153] In some embodiments, before forwarding a tool call to the underlying operating system, the controlled execution module re-verifies whether the call strictly falls within the envelope defined by the approved managed execution contract. The system extracts the planned action set, the allowed read set, and the allowed write set (instance field names are plannedActions, allowedReadSet, and allowedWriteSet, respectively) from the managed execution contract as a safety baseline.
[0154] When the tool is actually running downstream, the actual resource paths it reads or writes will be objectively captured by the system and recorded as the actual read resource set and the actual write resource set (instance field names are actualReadSet and actualWriteSet, respectively). During the data backflow phase after execution, the system immediately executes the side effect comparison logic: if it detects that the actual write resource is not included in the allowed write set of the managed execution contract or the allowed write set of the global approval decision, the system will explicitly record this abnormal behavior as an out-of-scope access record (instance field name is outOfScopeAccesses), and based on this, directly mark this action as a verification failure candidate in the subsequent reconciliation process, thereby blocking potential privilege escalation or pollution behaviors.
[0155] To ensure the objectivity and tamper-proof nature of the actual read and write resource sets, the tool call interception layer deploys differentiated low-level observation methods for different types of external tools. These include: for file read / write tools, a file tool wrapper at the system kernel level takes over, specifically recording the normalized absolute paths of opened, read, written, renamed, or deleted files; for shell commands or system scripts, relying on command execution sandboxes, file system monitors (such as eBPF probes), or command wrappers, objectively recording all files, environment variables, network endpoints, and the final process exit status actually touched by the process; and for browser automation operations, the browser driver layer... (Such as WebDriver proxy) At the underlying level, it records the reading actions of the Document Object Model (DOM), form submission events, file downloads and uploads, clipboard interactions, and page navigation events; for database connections, a dedicated database proxy or software development kit (SDK) wrapper intercepts and parses the traffic, recording the actual database table names accessed, the primary key range touched, the type of statement executed (such as SELECT or UPDATE), and transaction boundaries; for external API calls, a network gateway, reverse proxy, or SDK wrapper uniformly records the HTTP request method, the normalized API endpoint address, the authentication context, and the server's response status code.
[0156] Furthermore, for black-box tool calls that cannot be fully covered by the observation path due to limitations of the underlying environment, the system implements a downgraded security strategy. That is, any call action that cannot obtain a complete resource read and write trajectory is marked as incomplete observation (e.g., instance field name is observabilityIncomplete). In the subsequent machine reconciliation process, the highest verification result of a call action carrying this incomplete observation mark can only be a warning. Moreover, when the estimated risk level of the call exceeds the preset security threshold, or when its action type declaration involves write side effects, the system will directly hard upgrade its verification result to failure, thereby preventing the agent from using the blind spot of observation to execute uncontrolled high-risk changes.
[0157] The following section will describe in more detail how to store the external return content generated by the operation into a preset isolated storage area.
[0158] Reference Figure 6 The external return content generated by the operation is stored in a preset isolated storage area, including the following steps 601 to 603.
[0159] Step 601: Maintain write isolation between the control isolation storage area and the contract storage area that stores the current execution boundary.
[0160] Step 602: Perform compliance verification on the external returned content in the isolated storage area, and after the compliance verification is passed, use the external returned content as revision input to generate a new version candidate boundary.
[0161] Step 603: Replace the current execution boundary with the new version candidate boundary.
[0162] Steps 601 to 603 are described in detail below.
[0163] In step 601 of some embodiments, write isolation is maintained between the control isolation storage area and the contract storage area storing the current execution boundary. When an external tool call completes and generates untrusted external return content, it is physically or logically routed to a preset isolation storage area R_{iso}. At this time, at the underlying execution path, a cross-region access control policy is implemented to block any direct or indirect write instructions from the isolation storage area R_{iso} to the contract storage area. That is, a runtime data flow invariant is maintained, so that the external return content is restricted to a sandbox environment and cannot be tampered with by pointer overflow, variable overwriting, or context sharing in the protected fields of the current execution boundary C that are sealed in the contract storage area.
[0164] The contract storage area refers to the privileged storage area used to securely store the current execution boundary (i.e., the managed execution contract C) and its protected fields, and it has anti-tampering properties.
[0165] In step 602 of some embodiments, the external return content in the isolated storage area is subjected to compliance verification. After the compliance verification is passed, the external return content is used as revision input to generate a new version candidate boundary. At this time, the external return content in the isolated state can only be further utilized by the system after an explicit trust-based process. Specifically, a preset read-only verifier is invoked to perform compliance verification on the format, content, or security features of the external return content in the isolated storage area, or it is handed over to a qualified person for explicit labeling. Only when the compliance verification is passed (i.e., the risk of malicious injection or unauthorized guidance is excluded) is the untrusted label of this part of the data removed. Subsequently, this verified external return content is extracted as a legitimate revision input parameter. Combined with the original workflow intent, a completely independent new version candidate boundary C' is re-instantiated in memory. This process strictly follows the non-destructive write principle. The generation process of the new version candidate boundary C' will not produce any data overwrite operation on the original current execution boundary C$.
[0166] Among them, the new version candidate boundary refers to the independent boundary object C' that is re-instantiated after absorbing compliant external content. This object does not interfere with the original current execution boundary and does not undergo in-situ modification.
[0167] In step 603 of some embodiments, the current execution boundary is replaced by a new version candidate boundary. After generating an independent new version candidate boundary C', to ensure that subsequent tool invocation requests can be validated based on the latest legal context, a control baseline switch is required. This involves transferring the system's effective boundary pointer from the original current execution boundary C to the new version candidate boundary C' through a control state machine transition, thereby completing the overall policy replacement operation. At the moment the replacement is completed, the original current execution boundary C irreversibly enters a stale state, prohibiting it from being referenced by any subsequent tool invocation requests. This replacement-based rather than in-situ modification update mechanism ensures that every boundary change is accompanied by a complete reauthorization and hash digest recalculation, maintaining the continuity of the defense chain.
[0168] Through steps 601 to 603 above, for external untrusted payloads introduced during the execution of the intelligent agent, the path of direct tampering with the execution contract by prompt word injection is cut off by the underlying write isolation physical barrier. It also requires that external data must undergo explicit compliance verification and boundary replacement process, so as to eliminate the intention drift risk caused by the mixed sharing of external content and internal control instructions in the traditional workflow. While ensuring that the intelligent agent can dynamically absorb external knowledge, it maintains the absolute integrity and tamper resistance of the execution boundary data.
[0169] Reference Figure 7This is a schematic diagram illustrating the linkage timing of a tool call interception layer three-mechanism according to an embodiment of this application. Figure 7 The diagram illustrates the sequential execution logic of the sealing verification module (mechanism A), the multi-dimensional authorization coverage determination module (mechanism B), and the external content isolation determination module (mechanism C) in a single tool call process at the tool call interception layer.
[0170] In practice, when an agent initiates a tool call request with parameters (i.e., initiates a tool call request), the system first determines whether the request meets the preset managed execution trigger conditions. If the managed conditions are not met, the call request is directly transferred to the normal execution path, where the actual target tool executes the request and returns the result. If the managed conditions are met, the system formally enters the managed execution interception and verification process.
[0171] In the managed execution interception process, the tool invoking the interception layer first triggers the seal verification module (mechanism A) to perform boundary tamper-proof verification. This module recalculates the hash digest of the currently protected field (e.g., recalculates the SHA-256 digest) and compares it with the pre-stored baseline digest value (storedSeal). When the seal comparison result (sealCheck) indicates inconsistency (i.e., fail), the system triggers a contract invalidation operation (i.e., marks the contract as SUPERSEDED and files it), writes it to the decision ledger, and simultaneously rejects the call from the agent caller and triggers the corresponding revision process.
[0172] When the archived comparison result indicates consistency (i.e., pass), the system allows the call to proceed to the next verification node, where the tool calls the interception layer to initiate an eight-dimensional authorization coverage determination. At this point, the multi-dimensional authorization coverage determination module (mechanism B) verifies whether the pre-stored single authorization decision can completely cover the candidate call across all attribute dimensions. During this process, it strictly restricts the aggregation of multiple partially covering decisions. If the coverage determination result (authPass) is a failure, the system records the authorization coverage event in the decision ledger, rejects the call, and prompts the caller for approval and supplementation.
[0173] If the multi-dimensional coverage determination result is "pass," the process further proceeds to the external content isolation determination module (mechanism C) for parameter-level security isolation verification. Specifically, this module checks whether the request parameters of this call contain content with an external isolation flag (such as the R_iso flag) and verifies whether the write isolation constraint (i.e., the noDirectWritePath constraint) is maintained in the system's runtime environment. If the isolation verification result (isoCheck) is "fail," the system will record the isolation violation event in the decision ledger, reject the current call, and proceed to the external content pending trust path.
[0174] Only after the aforementioned sealing verification mechanism, multi-dimensional authorization coverage judgment mechanism, and isolation security verification mechanism have all passed sequentially, will the tool call interception layer formally allow the call request and hand it over to the actual target tool for execution. After the actual target tool completes execution and returns the execution result, the tool call interception layer writes the execution status and the associated three-vector verification success evidence (i.e., sealCheck, authPass, and isoCheck evidence) into the execution evidence set. Simultaneously, the system synchronously records the successful execution in the decision ledger, and finally securely returns the call result to the agent caller. This sequential linkage design effectively closes the defense surface in the agent tool call process in practical applications, ensuring the absolute compliance and secure controllability of high-risk operation steps.
[0175] Step 104: Based on the current execution boundary and actual execution records, determine the actual execution side effects of the candidate tool call requests item by item, and obtain the determination analysis results.
[0176] Step 104 is described in detail below.
[0177] In step 104 of some embodiments, based on the current execution boundary and actual execution records, the actual execution side effects of candidate tool call requests are determined item by item to obtain a determination analysis result. After the tool call is completed, a post-event reconciliation and verification stage is entered. By comparing the current execution boundary C obtained beforehand with the actual execution records E collected during the process, the actual execution side effects are extracted. This determination process verifies, through defined machine logic, whether the actual call identifier, tool type, and actual resource read / write actions fall within the intersection of the pre-declared authorization scope, and whether the execution status meets the predetermined success conditions. When the actual execution side effects fully meet the expectations and boundary constraints, a determination analysis result indicating successful reconciliation is output; conversely, if deviation side effects such as action deviation, out-of-bounds reading of confidential resources, or out-of-bounds writing of integrity resources are identified, a determination analysis result indicating failed reconciliation is output.
[0178] Among them, actual execution side effects refer to the objective state changes or resource access behaviors that occur when the candidate tool call actually reaches the downstream target resource, such as the actual underlying file reading action, data writing action, etc.
[0179] The following section will describe in detail how to determine the actual execution side effects of candidate tool call requests item by item.
[0180] Reference Figure 8 Based on the current execution boundary and actual execution records, the actual execution side effects of candidate tool call requests are determined item by item to obtain the determination analysis results, including the following steps 801 to 803.
[0181] Step 801: Analyze the current execution boundary to obtain the planned action.
[0182] Step 802: Compare the planned actions with the actual execution records to obtain the feature comparison results.
[0183] Step 803: When the feature comparison result indicates that there is a call identifier associated with the planned action in the actual execution record, and the actual call type in the actual execution record is consistent with the planned action, and the actual resource access set in the actual execution record does not exceed the authorized scope of the planned action, and the actual execution result in the actual execution record meets the success criteria of the planned action, a judgment analysis result indicating that the reconciliation has passed is generated.
[0184] Steps 801 to 803 are described in detail below.
[0185] In step 801 of some embodiments, when the agent's tool invocation action is completed and enters the post-verification stage in the managed execution path, it is necessary to first determine the reconciliation benchmark. Therefore, firstly, the planned actions are obtained by parsing based on the current execution boundary. Specifically, the current execution boundary C associated with the current execution task is read, and its internal structured fields (such as the plannedActions list) are semantically parsed to extract each pre-declared necessary planned action a_k in the current workflow. This parsing step breaks down the macro-level objectives that were originally mixed in the overall execution contract into verification units with granularity refined to the level of a single operation, thereby providing a clear and non-repudiable formal judgment benchmark for subsequent item-by-item reconciliation.
[0186] The current execution boundary refers to the structured managed execution contract (C) generated and authorized before the tool is invoked, which clearly defines the legal scope of the agent's current execution operation; the planned action refers to the pre-declared necessary task (a_k) parsed from the above current execution boundary, which internally specifies the tools expected to be used for the task, the resources that are allowed to be accessed, and the success criteria.
[0187] In step 802 of some embodiments, the planned action is compared with the actual execution record to obtain the feature comparison result. After obtaining the planned action a_k as the baseline, the actual execution record E objectively collected and generated by the system during execution is retrieved. Then, for each parsed planned action a_k, the corresponding mapping relationship between the plan and the actual is found and established in the set {t_j} of all actual tool call instances contained in the actual execution record E. On this basis, the pre-defined attribute features in the planned action a_k are compared with the corresponding attribute features objectively recorded in the actual call instance t_j in a multi-dimensional comparison operation. This process is equivalent to constructing and running a multi-feature element judgment function P(a_k, E) to evaluate the degree of deviation between the actual operating system-level side effects and the pre-planned expectations, and outputting an objective feature comparison result.
[0188] In step 803 of some embodiments, when the feature comparison result indicates that there is a call identifier associated with the planned action in the actual execution record, and the actual call type in the actual execution record is consistent with the planned action, and the actual resource access set in the actual execution record does not exceed the authorized scope of the planned action, and the actual execution result in the actual execution record meets the success criteria of the planned action, a judgment analysis result indicating that the reconciliation has passed is generated. Specifically, the judgment function P(a_k, E) includes multiple independent dimensions of logical conjunction judgment. First, an existence judgment is performed, that is, it verifies whether there is an actual call instance t_j in the actual execution record E that is explicitly associated with the planned action a_k (i.e., t_j ∈ E.toolCalls). Next, a type consistency check is performed to verify whether the actual tool name and action type of the instance t_j are strictly consistent with the type declared by a_k (i.e., t_j.toolName == a_k.toolName). t_j.actionType == a_k.actionType). Then, perform another resource access inclusion check to verify whether the resource paths actually read and written by t_j are included within the union of the allowed resource range declared by a_k and the system-authorized range (i.e., t_j.actualReadSet). (a_k.allowedReadSet ∪ approvedReadSet) and t_j.actualWriteSet (a_k.allowedWriteSet ∪ approvedWriteSet)). Finally, the expected result satisfaction is determined. Based on machine primitives such as process exit codes, structured assertions, or external responses, it is verified whether the execution status of t_j has met the preset success criteria of a_k. The system confirms that the operation has not exceeded the limits or drifted in terms of confidentiality, integrity, and business intent, and generates a judgment analysis result indicating that the reconciliation has passed, only if the multi-dimensional verification conditions are met simultaneously (i.e., the conjunction operation of all predicates evaluates to true). If any dimension is not met, the corresponding result of reconciliation failure is output.
[0189] In some embodiments, once the managed execution contract is approved and its legality is verified, the system's controlled execution module will strictly execute the corresponding tool calls according to the pre-declared set of planned actions. To reduce system coupling and improve engineering feasibility, the controlled execution module's architecture does not require a complete refactoring or replacement of the agent's original "reasoning-action-observation" loop mechanism. Specifically, this module introduces a managed checkpoint at the interception point where the tool call reaches the target resource by wrapping the central tool call path. This lightweight, non-intrusive integration method allows the agent to be forced into the constraints of the pre-declared execution boundaries without changing the reasoning architecture of the large language model when executing high-risk tool calls, while fully preserving the underlying execution evidence records.
[0190] In some embodiments, before forwarding a tool call to the underlying operating system, the controlled execution module performs a boundary check to confirm whether the call falls within the envelope defined by the approved managed execution contract. The system extracts the planned action set, the allowed read set, and the allowed write set (instance field names are plannedActions, allowedReadSet, and allowedWriteSet, respectively) from the managed execution contract as a security baseline for precise comparison to ensure that the issued actions have clear pre-declared credentials.
[0191] During the actual execution of the tool, the system's underlying observation path continuously tracks and structurally records the actual tool call instances, return status, output summaries, error messages, resource access information, and key runtime events, thereby generating an irrefutable record of actual execution. In a further preferred embodiment, to ensure the objective acquisition and tamper-proof nature of the actual read resource set and the actual write resource set (instance field names actualReadSet and actualWriteSet, respectively), the tool call interception layer deploys differentiated underlying observation detectors for different types of external tools, including: for file read / write tools, a file tool wrapper at the system kernel level takes over, specifically recording the normalized absolute paths of those opened, read, written, renamed, or deleted; for Shell commands or system scripts, relying on command execution sandboxes, file system monitors (such as eBPF probes), or command wrappers, objectively recording all files actually touched by the process, Environment variables, network endpoints, and the final process exit status are recorded. For browser automation operations, the browser driver layer records Document Object Model (DOM) reading actions, form submission events, file downloads and uploads, clipboard interactions, and page navigation events. For database connections, a dedicated database proxy or Software Development Kit (SDK) wrapper intercepts and parses the traffic, recording the actual database table names accessed, the primary key range touched, the type of statement executed (such as read-write separation semantics), and transaction boundaries. For external API calls, the network gateway, reverse proxy, or SDK wrapper uniformly records the HTTP request method, the normalized API endpoint address, the authentication context, and the server's response status code.
[0192] During the data feedback phase after execution, the system immediately executes the side-effect reconciliation logic based on the evidence collected by the multimodal observation mechanism. If it is detected that the resources actually read or written by the tool are not included in the allowed write set of the managed execution contract or the allowed write set of the global approval decision, the system will explicitly record this abnormal behavior as an out-of-scope access record (instance field name outOfScopeAccesses), and accordingly mark this action as a verification failure candidate in the subsequent verification process, thereby blocking potential privilege escalation or data pollution behaviors.
[0193] Furthermore, for black-box tool calls that cannot be fully covered by the aforementioned observation paths due to limitations in the underlying environment, the system implements a strict degradation security strategy. Any call action that cannot obtain a complete resource read / write trajectory will be forcibly marked as incomplete observation (instance field name: observeabilityIncomplete). In the subsequent machine judgment stage, the highest verification result for a call action carrying this mark can only be a warning; if and only if the estimated risk level of the call exceeds the preset security threshold, or if its action type declaration involves substantial side effects such as writing, the system will directly hard-upgrade its verification result to a failure, thereby preventing the agent from using the blind spots of the underlying observation to execute uncontrolled high-risk changes.
[0194] Through steps 801 to 803 above, after the intelligent agent completes the operation, this embodiment of the application compares the pre-declared planned actions with the objectively captured actual execution records using multi-dimensional features. This avoids the blind spot of judging whether high-risk tasks are completed in compliance with regulations based solely on the subjective reasoning of the large language model or unstructured logs. It effectively closes the security control chain of the intelligent agent's managed execution, ensuring that any abnormal behavior such as not executing according to plan, unauthorized modification of action types, or resource over-boundary reading and writing can be accurately detected. This improves the audit tracing capability and operational credibility of the intelligent agent system in complex workflows.
[0195] Step 105: Based on the judgment analysis results, perform migration control on the operation state of the intelligent agent.
[0196] Step 105 is described in detail below.
[0197] In step 105 of some embodiments, the agent's operating state is transitioned based on the decision analysis results. This allows the agent to determine the direction of its subsequent workflow after completing the current action based on the output deterministic decision analysis results. When the decision analysis results indicate that post-reconciliation is completely successful, the agent's managed operating state is allowed to smoothly transition towards accepting the action and continuing to process the next step. However, when the decision analysis results indicate that there are side effects exceeding limits or the execution process is non-compliant, a safety convergence mechanism is triggered, forcibly transitioning the operating state to a state that rejects the current execution result or requires manual intervention for escalation. This avoids the security risks of relying solely on the agent's subjective reasoning to determine whether a task is completed, as described below.
[0198] Reference Figure 9 Based on the judgment analysis results, the operation state of the intelligent agent is transferred and controlled, including the following steps 901 to 902.
[0199] Step 901: When the analysis result indicates that the actual execution record exceeds the authorized scope, or the actual call type in the actual execution record is inconsistent with the planned action, a reconciliation failure result is generated.
[0200] Step 902: Based on the reconciliation failure result, restrict the operation state of the intelligent agent to either the rejection state or the manual upgrade and handling state.
[0201] Steps 901 to 902 are described in detail below.
[0202] In step 901 of some embodiments, after completing the item-by-item judgment for each feature element, the judgment analysis results are classified and graded. When the judgment analysis result indicates that the actual execution record exceeds the authorized scope, or the actual call type in the actual execution record is inconsistent with the planned action, a reconciliation failure result is generated. Specifically, when the pre-declared required planned action is a_k, the actual execution record is E, and the actual tool call instance contained in the record is t_j, if the judgment analysis result shows that the actual execution record exceeds the authorized scope, for example, the resource set actually written is not included in the union of the planned write set and the approval decision allowed write set (i.e., t_j.actualWriteSet), (a_k.allowedWriteSet ∪approvedWriteSet)) indicates that the operation has breached the system's integrity boundary; or, if the analysis results show that the actual call type is inconsistent with the planned action, for example, the agent attempts to execute a tool with write or execute permissions with read action authorization (i.e., t_j.actionType). (a_k.actionType), which indicates that the operation involved semantic substitution and substantive privilege escalation.
[0203] The actual call type refers to the semantic type of the underlying tool action objectively captured in the actual execution record (such as file reading, file writing, system command execution, etc.), which reflects the true physical nature of the operation.
[0204] Furthermore, the two types of deviations mentioned above (i.e., resource write out of bounds and inconsistency in action type) touch upon the core bottom line of security control. Therefore, when the conjunctive logic P(a_k, E) of feature comparison evaluates to false for either of the above reasons, the judgment mechanism no longer outputs ordinary warning information, but directly outputs a reconciliation failure result classified as the highest severity. This reconciliation failure result, along with the specific feature sub-item that is falsified (such as the specific out-of-bounds path or mismatched type identifier), will serve as a verifiable payload for subsequent auditing and handling.
[0205] Among them, the reconciliation failure result refers to the failure (Fail) flag output by the decision logic when the side effects produced by the actual execution deviate significantly from the pre-plan or authorization envelope, and has monotonic and irreversible characteristics.
[0206] In step 902 of some embodiments, based on the reconciliation failure result, the agent's operating state is restricted to either the rejection state or the manual escalation state. After obtaining a clear reconciliation failure result, the state machine transition of the managed execution control flow is triggered. That is, according to the monotonicity principle of reconciliation judgment, the reconciliation failure result is irreversible on the state transition graph. The system hard-cuts off the direct transition edge from the reconciliation failure result to acceptance and continued execution of subsequent workflows at the underlying control logic.
[0207] Furthermore, the subsequent operational state of the agent is converged to two safe handling paths: the first is a rejection state (i.e., Revise handling), which blocks the current operation and requires the agent to regenerate a revised plan that does not exceed the limits or to supplement the execution; the second is a manual escalation state (i.e., Escalate handling), which suspends the agent's execution flow and transfers the execution context, the evidence package of the exceedance, etc., to a human operator for approval or intervention when the exceedance behavior is serious or cannot be safely repaired by automated logic. This avoids the automated agent from executing rollbacks or blindly retrying operations that may further expand the scope of side effects when the context is contaminated or the action is out of control.
[0208] In some embodiments, once the controlled execution phase of the agent is complete, the system verification module initiates a multi-dimensional machine verification process based on the generated set of execution evidence and the managed execution contract. To comprehensively cover all potential risk exposures, the verification module internally runs one or more independent verifiers in parallel or serially. These validators may include, but are not limited to: action reconciliation validators, responsible for verifying whether the pre-declared necessary tool actions in the managed execution contract have been actually executed and successfully completed, and determining whether their side effects have exceeded the limits; approval scope validators, responsible for tracing the decision ledger, checking whether the approval required for the current operation has been recorded as approved, and whether the authorization boundary of the approval record fully covers the current actual action; contract completeness validators, responsible for reviewing the quality of the managed execution contract itself, checking whether it lacks necessary governance elements such as success criteria, verification plans, or rollback plans; security posture validators, responsible for performing global context security level checks, focusing on checking whether there is a high-risk combination of "insecure public trigger sources" and "lax approval policies" in the system configuration; and custom domain validators, which are extended interfaces provided for specific business scenarios, such as compliance validators, financial slippage validators, deployment health validators, or data consistency validators.
[0209] After performing the corresponding rule checks, each validator will output an independent judgment status (e.g., pass, warning, or fail). These fine-grained verification results will be uniformly aggregated and written into the execution evidence set, and then passed to the downstream processing decision module.
[0210] In some embodiments, to eliminate the subjective illusion of large language models in result determination, the tool action reconciliation validator performs a five-element formal reconciliation determination algorithm for each required planned action in the managed execution contract, as described below. Let the pre-declared required planned actions be a_k, and the actual collected execution evidence set be E. This determination process is equivalent to solving a multidimensional logical conjunction function P(a_k, E). Specifically, the computational logic of this function is as follows.
[0211] P(a_k, E) = tc ∈ E.toolCalls : a_k tc / / existence ∧ tc.toolName == a_k.toolName ∧ tc.actionType == a_k.actionType / / type ∧ tc.actualReadSet (a_k.allowedReadSet∪ approvedReadSet) / / read ∧ tc.actualWriteSet (a_k.allowedWriteSet ∪ approvedWriteSet) / / write ∧ expectedOutcomeSatisfied(tc.output, a_k.expectedOutcome) / / outcome In this formal decision logic, the system checks five core elements one by one: First, existence, checking whether there is a call instance tc in the actual tool call set (toolCalls) of evidence set E that is exactly associated with the planned action a_k; second, type consistency, checking whether the actual tool name and action semantics are completely consistent with the plan; third and fourth, confidentiality and integrity boundary coverage, checking whether the actual read resource set and write resource set are included in the union of the plan's allowed range and the global approval allowed range, respectively; fifth, expected result satisfaction, checking whether the actual output meets the preset success standard. The reconciliation decision function outputs a global pass result if and only if the results of the above five predicate operations for all planned actions a_k are true; if any necessary action is found to be missing in the operation, or if a decision is false and the reason is "actual write set out of bounds" or "tool action type inconsistency", the system will directly output the highest level failure result or trigger a forced escalation.
[0212] For the expected outcome satisfaction determination in the above functions, the system employs a variety of objective machine primitives as support. This determination can be based on a comprehensive evaluation of one or more of the following: structured assertions, process exit status codes, underlying file difference comparisons, database transaction commit results, external API response field validation, browser page DOM state extraction, regression test case outputs, or authorized human signature records. For some non-deterministic outputs caused by external environmental fluctuations, the validator preferably outputs a warning and records detailed information about the sub-items that cannot be deterministically verified. However, when the non-deterministic sub-item belongs to a high-risk write operation or involves the success criterion evaluation of irreversible side effects, the system's security degradation strategy will forcibly upgrade the warning status to failure to prevent unauthorized changes in a black-box state.
[0213] Furthermore, the security posture verifier deeply intervenes in the source context of operations. This verifier specifically checks whether high-risk or extremely high-risk operations originate from untrusted triggering sources such as public channels, group chat bots, or external webhooks, and simultaneously detects whether the operation has been incorrectly configured with automatic approval or a session-level broad approval policy. If the system detects the simultaneous occurrence of "untrusted public source," "high-risk tool action," and "broad approval policy," even if the action itself does not involve resource violations, the verifier will output a warning or fail, requiring the operator to tighten the approval scope or escalate the approval level.
[0214] After completing all the formal verifications above, the system performs deterministic transition control on the agent's operating state based on the comprehensive output level. The corresponding state machine transition logic is described below.
[0215] When all actions are judged as pass, the running state smoothly transitions to the Accept (ACCEPT) state, allowing the workflow to continue. When a warning is present in the judgment result, but the system assesses the overall risk level of the current task as less than or equal to the preset safety threshold, the state transitions to the Accept with notes (ACCEPT with notes) state, allowing low-risk tasks to proceed while recording risk exposure. When a warning is present in the judgment result, and the overall risk level of the task exceeds the preset threshold, the warning is upgraded to fail, and the state transitions directly to the ESCALATE state, requiring manual intervention for review. When the above five-element judgment function directly outputs fail due to severe write out of bounds or type tampering, the system hard-blocks the automated control flow, forcibly transitioning the state to the Reject or ESCALATE state.
[0216] Based on the state machine with mathematical logic verification and degradation strategy, the embodiments of this application can achieve a high out-of-bounds write detection rate and planned-actual-action coverage rate in complex and ever-changing intelligent agent execution environments, ensuring that the probability of erroneously accepting serious out-of-bounds behavior approaches zero.
[0217] In some embodiments, after receiving the comprehensive verification result output by the verifier system, the decision-making module in the system uses this as the sole basis for machine authorization, determining the final flow state of the agent's managed control flow. Specifically, the system's underlying design includes four clear and mutually exclusive state transition branches: the first is the Accept branch, where the system removes the managed blockade when all necessary formal verifications for actual execution side effects (such as action consistency, resource read / write inclusion, etc.) are deemed passed, allowing the agent to accept the current execution result and smoothly advance the subsequent workflow; the second is the Revise branch (i.e., rejecting the current result and requesting a retry), where the state transitions to the Revise branch when the execution result is found to be inconsistent with expectations during verification, but the problem falls within the system's pre-judged repairable range (e.g., non-fatal resource read failure or missing tool parameters). The system blocks the current path and returns specific verification failure feedback to the agent, requiring it to revise the execution plan or proceed based on this feedback. The first step is supplementary execution; the second step is escalate handling. When core verification fails severely (such as lack of prior approval, substantial out-of-bounds reading and writing of resources, or semantic substitution of tools), or the security posture configuration is judged to be extremely high-risk (such as high-risk operations superimposed on untrusted public sources), and such anomalies cannot be automatically and logically repaired by the system, the state will be transferred to the escalate branch. At this time, the agent's automated process will be suspended, the system will generate an alarm payload containing out-of-bounds evidence, and transfer it to a human operator or a higher-level security entity for analysis and handling; the third step is controlled rollback handling. Only when the security rollback mechanism is explicitly enabled in the system's macro configuration, and the current actual execution context matches the pre-declared rollback plan conditions, can the system choose to execute a controlled rollback operation.
[0218] In some embodiments, the system does not use automatic rollback as the first-line response to verification failures. Instead, it uses "Revise" or "Escalate" as the default handling path. When high-risk operations (such as system configuration modifications or core database updates) go out of bounds or drift in intent, the agent's current contextual awareness is often incomplete or contaminated. If the automated system is allowed to blindly attempt rollback based on its "illusion" at this time, it will not only be difficult to restore the original state, but it is also prone to triggering more serious secondary failures or expanding the operational blast radius.
[0219] To ensure the system remains in a safe convergence state after a failure, this application imposes a threshold restriction on entering the "Controlled Rollback" branch. Automatic rollback is allowed only if the following four constraints are simultaneously met: 1) a detailed and executable rollback plan is explicitly stated in the pre-declared managed execution contract; 2) the specific compensation actions included in the rollback plan have been explicitly approved by the system or manually in advance; 3) objective data collected in the execution evidence set is sufficient to prove that the actual side effects of the erroneous operation are physically or logically reversible; and 4) the risk level of the pre-declared rollback operation itself, after a safety posture assessment, is no higher than the originally planned high-risk operation, or the high-risk rollback has been separately approved as a special case. If any of the above conditions are not met, the system will immediately block the automatic rollback attempt and forcibly downgrade the operating state to a more conservative "Revise" or "Escalate" handling branch requiring manual intervention. This handling logic avoids uncontrolled autonomous repair behavior of intelligent agents when encountering complex faults, and improves the controllability of the system in high-risk scenarios.
[0220] Through steps 901 to 902 above, a secure convergence mechanism based on machine-defined rights is constructed in the post-action verification stage of the agent. This mechanism directly maps substantive out-of-bounds and type tampering behaviors identified during the reconciliation process into reconciliation failure results with blocking effect. Based on this, the subsequent running state of the agent is restricted at the state machine level, effectively preventing high-risk operations from being mistakenly allowed after deviating from the authorized track. This ensures that the action boundaries of the agent in complex and unpredictable operating environments are always within a controllable, verifiable, and blocking secure closed loop.
[0221] Reference Figure 10 This is a schematic diagram of a verifier architecture provided in an embodiment of this application. Figure 10 The diagram illustrates the overall process by which, after the tool call execution is completed, the system runs multiple independent validators to conduct a comprehensive multi-dimensional check on the managed execution contract, execution evidence set, decision ledger, and managed execution configuration items, and then aggregates the results and makes subsequent processing decisions based on the set of verification results.
[0222] Specifically, the verification module runs one or more independent validators for verification and checks. The tool action reconciliation validator receives the managed execution contract and execution evidence set as input parameters to check whether the required tool actions pre-declared in the managed execution contract have been actually executed and successfully completed. The contract completeness validator, based on the content of the managed execution contract, checks whether it lacks necessary governance elements such as success criteria, verification plans, or rollback plans. The approval scope validator, combining the managed execution contract and records in the decision ledger, checks whether the approval required for the current operation has been recorded as approved, and further verifies whether the authorization scope of the approval record effectively covers the currently executed action. The security posture validator, based on the managed execution configuration items and the managed execution contract, checks whether there are high-risk scenarios in the current system configuration that combine insecure public triggers with lenient approvals. In addition, the system also supports inputting the execution evidence set and contract into a custom domain validator, allowing users or third parties to extend the verification logic for specific business domains such as execution compliance, deployment health, or data consistency.
[0223] After completing their respective rule checks, each validator outputs a verification status of pass, warning, or fail. These status data collectively form a verification result set. The system then performs result aggregation processing on this set and transfers it to the final state transition and handling decision-making stage. During the handling process: when all necessary verifications have no failures and existing warnings are within acceptable limits, an accept status is generated; when verification results indicate the existence of supplementary execution items or repairable issues, a revised status is generated to require supplementary execution; when non-automatically repairable security blocking events occur, such as missing approvals, failed security posture verification, or insecure configurations, an escalate status is generated and the process is handed over to a human operator; when the system explicitly enables secure rollback configuration and the current execution evidence set meets preset explicit rollback conditions, a controlled rollback status can be generated. This architecture ensures that when an agent performs high-risk operations and produces actual side effects, it receives machine-determinable, standardized closed-loop verification and secure handling guarantees.
[0224] Reference Figure 11 This is a schematic diagram of a multi-agent shared state provided in an embodiment of this application. Figure 11 The diagram illustrates how, in scenarios involving multiple agents or participants collaboratively processing tasks, the system centrally records the operational trajectories of each participant through a unified collaborative managed state, and implements concurrent conflict detection and state consistency maintenance.
[0225] In multi-agent collaboration scenarios (such as software development pipelines), the system typically includes agents with different business roles. For example... Figure 11 As shown, the example includes a Programmer Agent, a Reviewer Agent, and a Tester Agent. Each participant generates corresponding action instructions during their assigned workflow stage, such as coding, reviewing, and testing actions. These actions and their contextual information from different participants are aggregated and registered in a "collaborative managed state" for global management.
[0226] Furthermore, this collaborative managed state internally maintains execution tracking sub-items across multiple dimensions in a structured manner. Specifically, this state not only aggregates the actions executed or planned to be executed by each participant, but also records in detail the read and write resource sets (readSet and writeSet) involved in these actions, the resource versions (versionDependencies) on which the actions depend, the assumptions declared by the participants, and the associated evidence bundle identifiers (evidenceBundleIds). This structured state aggregation provides complete data support for subsequent cross-agent collaborative verification and dual failure propagation.
[0227] Based on the multi-dimensional data recorded in the collaborative managed state, the system will run conflict detection logic. This conflict detection module primarily uses resource version numbers and hypothesis statements as judgment criteria to cross-compare concurrent operations or temporal dependencies. Based on the comparison results, it can identify and output various types of conflict events: a write-write conflict is generated when multiple participants (such as programmer and tester agents) simultaneously attempt to write to the same target resource; a read-write conflict is generated when one participant (such as a reviewer agent) performs a read operation based on an older version of the resource, while another participant has already written to and updated that resource version; furthermore, it will verify the preconditions declared by participants and output hypothesis conflicts. Only when no anomalies are found in the conflict detection across all dimensions mentioned above will the system generate a conflict-free judgment result, allowing the current collaborative workflow to smoothly proceed to the next processing stage. This centralized state management and conflict detection mechanism effectively ensures the collaborative consistency and overall workflow security when multiple agents concurrently execute complex operations.
[0228] Reference Figure 12 This is a schematic diagram of a governance evolution proposal review process provided in an embodiment of this application. Figure 12The diagram illustrates the logical flow between failure mode detection, governance strategy improvement proposal generation, human review, governance ledger recording, and subsequent human application. Furthermore, this workflow architecture reflects the design principle of prioritizing review and avoiding automatic modification of runtime configurations.
[0229] When the system observes repeated failures in calling a certain type of tool or continuous warnings from a certain type of verification rule during operation, the evolutionary intervention process will be triggered. At this point, the system first analyzes the aforementioned abnormal events to identify the specific failure mode. Subsequently, the governance evolution proposal module automatically generates a structured governance strategy improvement proposal based on the identified failure mode. Specifically, to ensure the security and evaluability of the improvements, the proposal will detail key control elements such as the proposed changes, invariants that must be maintained, falsification testing, evaluation plan, canary deployment plan, and rollback plan.
[0230] After generating a complete governance strategy improvement proposal, the process enters the human review node. The system executes the corresponding branch based on the human review's judgment: if the human review determines the proposal is unacceptable, the system records it as rejected or prompts for further information; if the human review determines the proposal is accepted, the system persistently records the approved decision in the decision ledger. It is important to note that this embodiment applies a "review priority constraint" at this stage. The operator's approval of the proposal only indicates acceptance of the improvement suggestion at the management level; the system does not automatically modify the current runtime configuration accordingly. This constraint mechanism fundamentally avoids the risk of an agent unauthorizedly modifying its own governance strategy.
[0231] After a proposal is approved and recorded in the ledger, the corresponding policy modifications can be implemented through manual intervention or by integrating with external change processes. After the modifications are applied to the system, further testing methods such as regression testing, canary deployment verification, or continuous operational observation are needed to evaluate and confirm the actual effectiveness of the improvements. When actual operational verification determines that the improvement is effective, the system officially retains the new governance policy; conversely, if the improvement is found to be ineffective or leads to increased system operational risks during the observation period, the system will trigger and execute recovery operations according to the rollback plan preset in the proposal. Through this closed-loop process, this application provides a structured basis and standard path for the continuous optimization of governance rules while ensuring the absolute security of the managed execution environment.
[0232] Through steps 101 to 105 above, a managed interception loop is introduced at runtime along the path where the agent actually reaches the underlying resources during the execution of operations. This achieves a complete control flow design from pre-plan verification, in-process reverse isolation to post-event side effect formal reconciliation. It effectively cuts off the injection path for untrusted external content to directly tamper with the system's established rules, and ensures the determinism of the agent's operation boundaries and the security of data flow during multi-round, multi-tool invocation processes. This improves the closed-loop governance efficiency of the agent architecture when executing high-risk workflows.
[0233] Reference Figure 13 This is a schematic diagram of a managed execution process of planning-execution-verification provided in an embodiment of this application. For example... Figure 13 The diagram illustrates the sequential flow of intent capture, generation of managed execution contracts, approval governance, controlled execution, generation of execution evidence sets, operation of the validator system, and decision-making on the handling of verification results, as well as the branch logic that enters the execution path of a normal intelligent agent when the managed conditions are not met.
[0234] The entire execution process begins with receiving a user request or an intelligent agent tool invocation request. The system first performs intent capture and risk classification to determine whether the current operation request meets the preset managed conditions. If the result is that the managed conditions are not met (e.g., for a regular low-risk query task), the request will be directly transferred to the normal intelligent agent execution path for normal processing. Conversely, if the result is that the managed conditions are met, the system will formally initiate the managed control flow and generate the corresponding managed execution contract based on the current context and operation intent.
[0235] Subsequently, the generated managed execution contract flows to the Approval / Governance stage. In this stage, the system determines whether the current operation has passed approval. If approval fails, the system will directly trigger an Escalate or terminate the operation, thus creating a physical barrier before actual execution. If approval passes, the agent system will strictly execute the corresponding tool actions according to the pre-declared constraints in the managed execution contract. After the controlled tool actions are completed, the system collects the actual resource access and output records during execution to generate a corresponding execution evidence set.
[0236] After generating a complete set of execution evidence, the system further triggers and runs the validator system. The validator system performs machine reconciliation and compliance checks on the collected execution evidence set and the original managed execution contract, and outputs the verification results. Finally, based on the verification results, the system state machine will execute the corresponding final disposal decision: when the verification results show that all checks have passed, the system generates an Accept disposal status; when the verification results indicate that there are repairable problems, the system generates a Revise disposal status to request supplementation or modification; when the verification results find high-risk anomalies such as missing approvals or insecure system configurations, the system generates an Escalate disposal status and transfers it to manual intervention; when the system has explicitly enabled the rollback mechanism in advance and the current execution status meets the predetermined rollback conditions, the system generates a Rollback operation instruction.
[0237] Reference Figure 14 This is a schematic diagram of a managed execution system module provided in an embodiment of this application. Figure 14 The diagram illustrates the data flow and logical relationships between core modules such as intent classification, contract generation, approval governance, controlled execution, evidence package generation, and disposal decision-making, and intuitively demonstrates the state interaction mechanism in a multi-agent collaborative scenario.
[0238] In some embodiments, the system first receives a user request or agent action and classifies its intent and determines if it meets the conditions. If the request is determined to be low-risk or does not meet the managed conditions, it is directly routed to the normal execution path for regular processing. If the managed conditions are met, the managed execution control flow is triggered, and the contract generation module takes over and generates the corresponding managed execution contract.
[0239] After generating the managed execution contract, the approval governance module processes it according to the system's preset risk strategy and persistently records the generated approval decision in the decision ledger. Provided the approval is successful, the controlled execution module securely issues and executes the actual tool call based on the operational intent and boundary constraints defined in the contract. After tool execution, the resulting tool call results are processed by the evidence package generation module. This module is responsible for collecting and structuring various data during execution, generating an execution evidence set, and archiving it in the execution evidence set storage, providing a data foundation for subsequent machine reconciliation and compliance audits.
[0240] Based on the stored execution evidence set, managed execution contracts, and decision ledger, the system, after verification logic, transfers the data to the disposal decision module for final status determination. For example... Figure 14As shown, the decision-making module can output clear disposal instructions such as Accept, Revise, Escalate, or Rollback based on the results of comprehensive verification, thereby achieving closed-loop security control for high-risk operations at the system architecture level.
[0241] Furthermore, in multi-agent collaboration scenarios, the managed collaboration state serves as a global synchronization hub. On one hand, it provides the contract generation module with multi-agent read / write set information for each participant. On the other hand, it receives execution events and version dependencies continuously reported by the controlled execution module. Simultaneously, an independent verification module performs conflict detection and hypothesis verification based on this managed collaboration state to collaboratively maintain data consistency and the safety boundaries of the overall workflow during cross-agent concurrent execution.
[0242] In one embodiment, during routine R&D collaboration, users frequently request agents to perform tasks such as "modifying project configuration files to enable target features." When the agent captures this user intent and attempts to invoke external tools, the system's intent classification module intervenes. At this point, the system recognizes that the request involves a call to a write-type tool, and the write target is a core system project file. Therefore, this action precisely matches the write_tools trigger condition in the system configuration (e.g., the contractRequiredFor configuration item), and automatically enters the managed execution interception process.
[0243] During the managed execution interception phase, the contract generation module first generates a structured managed execution contract for this operation. This contract explicitly defines the global goal of this execution as "modifying the specified configuration file to enable the target function"; its pre-declared set of planned actions is refined to: reading the original configuration file, modifying the target configuration items in memory, overwriting and saving the modifications to a file, and running the pre-configuration verification command. Simultaneously, the contract defines strict boundaries: the read set is limited to the configuration file and related documentation being read; the write set is strictly limited to the configuration file to be modified; the risk level of this operation is automatically assessed and marked as medium or high; the verification plan includes running the configuration verification command and extracting the file modification differences (Diff); and the rollback plan explicitly restores the file to its initial state before modification using a backup.
[0244] Because the risk level of this operation matches the system's preset risk approval strategy (e.g., the requireApprovalForRisk configuration item), the approval governance module will suspend the agent's workflow and send an approval request to a qualified human operator. Once the operator verifies the contract content and clicks "approval," the system will remove the block, the controlled execution module will send tool call instructions to the underlying layer, and simultaneously generate an execution evidence set containing the actual read / write results, verification command output, and file difference summaries.
[0245] During the verification phase after execution, the tool action reconciliation verifier checks each of the aforementioned planned actions against the collected execution evidence set to ensure that all actions were successfully executed and no write-out occurred. Simultaneously, the contract integrity verifier checks whether the success criteria and rollback plan were effectively implemented. When all multi-dimensional verifications pass, the system's decision-making module smoothly transitions the agent's state to Accept. Conversely, if a configuration verification command fails, the system forcibly converges the state to Revise, requiring the agent to retry, or Escalate, leaving it to manual investigation.
[0246] In the second embodiment, in a system operation and maintenance scenario, a user might request the agent to "run a Shell command to fix network configuration problems in the current environment." Given the extremely high system penetration and unpredictability of the Shell environment, the system intent classification module will immediately classify the request as an extremely high-risk system-level operation, forcing it to enter the complete managed execution process of "plan-execute-verify".
[0247] Before actually issuing the shell command, the contract generation module forces the intelligent agent to output a detailed operation profile in the managed execution contract, including: a complete summary of the command to be executed, the core purpose of the command, the standard format of the expected output, the file paths or system processes that may be indirectly affected, quantified success criteria, and an emergency rollback plan in case the command causes a system crash. Subsequently, the approval and governance module presents this structured data to the operations administrator for secondary confirmation. All approval decisions and confirmation traces are immutably persisted to the decision ledger.
[0248] Once the controlled execution phase begins, the underlying command execution sandbox or command wrapper will take over the shell command. The system will collect execution data at the process level and record in the execution evidence set the actual executed shell command characters, process exit code (ExitCode), standard output stream (stdout), standard error stream (stderr), total execution time, and a summary of system call side effects extracted by the underlying interceptor.
[0249] In the post-execution verification phase, the tool action reconciliation verifier primarily relies on process exit codes and expected system signals to formally determine whether the command was truly successful. Simultaneously, the security posture verifier performs macro-environment compliance checks—for example, rigorously checking whether the high-risk Shell operation command originated from an untrusted public channel (such as a public group chat) and whether the current approval policy is configured too leniently. Based on the comprehensive verification results: if the command execution fails but does not produce irreversible system side effects, the system state transitions to revision, prompting the agent to adjust command parameters; if the command substantially touches upon sensitive boundaries of the production environment or triggers permission anomalies, the system hard-triggers escalation, severing the agent's subsequent control.
[0250] In the third embodiment, in a complex software engineering pipeline, a complete requirement typically requires collaboration from multiple agents playing different roles (e.g., programmer, reviewer, and tester agents). To prevent context tearing and data contamination caused by concurrent operations of multiple agents, this embodiment introduces a managed state for multi-agent collaboration.
[0251] In this scenario, the system generates independent managed execution contracts for each stage of the pipeline, including: a programmer stage contract, defining specific coding goals, the scope of allowed code files to be modified, coding style constraints, and a preliminary self-testing and verification plan; a reviewer stage contract, defining specific dimensions of code review (such as security and performance), the minimum passing score threshold, and a structured review output report format; and a tester stage contract, defining the test suite commands to be run, the minimum code coverage requirements, and the final test pass criteria. To coordinate these three parties, the system maintains a unified collaborative managed state in the background. This state aggregates and records the action instructions, resource read / write sets, and execution assumptions of the three participants in real time. The system relies on this state to perform high-frequency concurrent conflict detection: for example, when the programmer agent and the tester agent attempt to write to the same test configuration file simultaneously, the system will accurately capture and throw a write / write conflict; similarly, when the reviewer agent reviews a code file based on an older version, while the programmer agent has modified the file to a newer version, the system will sensitively detect a read / write conflict and block the invalid review.
[0252] During pipeline progression, each agent stage generates an independent set of execution evidence upon completion, and the state machine recorded in the decision ledger determines whether to allow it to proceed to the next stage. If the reviewer agent fails verification (e.g., a code vulnerability is discovered), the system generates a revision action, rolling back the pipeline state to the programmer stage for refactoring. If the tester agent stage repeatedly fails tests and exceeds the preset maximum number of revision attempts, the system generates an escalate action, freezing the entire pipeline and notifying human engineers to intervene.
[0253] To illustrate this mechanism more clearly, the following provides a minimal example of the underlying data structure for the collaborative managed state (the field names in this JSON data structure are the example names of the implementation).
[0254] JSON { "id": "shs-pipeline-001", "participants": [ {"role": "programmer", "sessionId": "sess-p1", "actorId": "agent-coder"}, {"role": "reviewer","sessionId": "sess-r1", "actorId": "agent-reviewer"}, {"role": "tester","sessionId": "sess-t1", "actorId": "agent-tester"} ], "actions": [ {"id": "act-p1", "actorId": "agent-coder", "harnessContractId": "hc-prog-001", "writeSet": ["src / foo.py"], "readSet": ["src / foo.py"]}, {"id": "act-r1", "actorId": "agent-reviewer", "harnessContractId": "hc-rev-001", "readSet":["src / foo.py"]}, {"id": "act-t1", "actorId": "agent-tester","harnessContractId": "hc-test-001", "writeSet": ["tests / test_foo.py"], "readSet": ["src / foo.py", "tests / test_foo.py"]} , "versionDependencies": {"actionId": "act-r1", "resource": "src / foo.py", "observedVersion": "v3"}, {"actionId": "act-t1", "resource": "src / foo.py", "observedVersion": "v4"} , "assumptions": {"id": "h1", "ownerActionId": "act-r1", "statement": "act-p1 has been completed before act-r1 starts", "state": "fresh"} , "evidenceBundleIds": ["eb-prog-001", "eb-rev-001"], "conflicts": { "type": "read_write", "resource": "src / foo.py", "writerActionId": "act-p1", "readerActionId": "act-r1", "writerVersion": "v4", "readerVersion": "v3", "detectedAt": "2026-05-28T10:15:00Z" } } In the above collaborative managed state data structure, a typical timing failure can be traced: the reviewer agent (act-r1) is currently performing code review operations based on the v3 version of the src / foo.py file; however, the system tracks that the programmer agent (act-p1) has overwritten and upgraded the file to version v4 during this period. Faced with this context break, the conflict detection module of the collaborative managed state immediately captures this discrepancy and generates a clear read_write event in the conflicts array.
[0255] Furthermore, this structure deeply supports a dual failure propagation mechanism. For example, the recorded hypothesis node h1 (declaring "before the review action act-r1 begins, the coding action act-p1 must be in a completed and frozen state") is officially falsified by the underlying machine verifier at this moment. Once this hypothesis is falsified, the system will forcibly mark the downstream review action act-r1 as stale along the operation dependency graph. This state failure will block the currently invalid workflow, requiring the reviewer stage to obtain the latest v4 source code, re-execute the verification, and apply for new approval authorization, thereby maintaining the bottom line of operational logic consistency amidst the chaos of multi-agent concurrency.
[0256] In the fourth embodiment, in extremely sensitive scenarios such as automated operations or financial transactions, intelligent agents typically need to perform extremely high-risk operations, such as generating trading suggestions, calling external third-party APIs, submitting real fund orders, or modifying production environment configurations in real time. Such operations not only have extremely low fault tolerance but also require a complete and non-repudiable audit chain for compliance purposes.
[0257] To address this type of scenario, the system in this application breaks down the complex, long-cycle workflow into finer-grained steps, such as signal generation, qualification checks, portfolio construction, order planning, instruction execution, and post-market analysis. Before each step begins, the contract generation module generates an independent managed execution contract that clearly defines the entry input data, trading decision rules, risk exposure thresholds, expected output data format, and success criteria for that step.
[0258] Before an actual order instruction is issued and executed, the approval governance module will perform pre-emptive verification, focusing on checking whether the current transaction risk assessment indicators, funding exposure limits, and market liquidity conditions are met, and verifying whether the approval status has been obtained from a human operator with the corresponding permissions. Only when all conditions are met can the order be released. After controlled execution, the system-generated execution evidence set not only records the regular call status but also structurally records key business indicators, such as order issuance parameters, actual transaction results, network latency, slippage, partial execution rate, and any abnormal market events.
[0259] Subsequently, a multi-dimensional validator system is deployed. In addition to checking whether the underlying tool calls return a successful technical response, the validators cross-check the existence and validity of approval documents and conduct in-depth verification of whether actual slippage and exposure exceed the risk thresholds locked in the managed execution contract. Based on the verification results: if all indicators are within the authorized range, the system smoothly processes the status to Accept; if excessive slippage, abnormal exposure, or tampering with the approval status is detected, the system immediately suspends the workflow and processes it as Escalate, handing it over to a risk control specialist; if the system has predefined clear and approved order cancellation or reverse hedging compensation steps, the system can also automatically trigger and execute controlled rollback or compensation operations, thereby achieving closed-loop management of the transaction workflow while ensuring fund security.
[0260] In the fifth embodiment, the underlying environment and business logic will dynamically change during the long-term operation of the intelligent agent system. When the system objectively observes, through the execution of evidence sets and judgment analysis results, that a certain type of tool call repeatedly fails, or a certain type of verification rule continuously issues warnings or other high-frequency operational events, the system will trigger an automated governance evolution intervention process.
[0261] At this point, the system's internal governance evolution proposal module analyzes the accumulated error patterns and automatically generates a structured governance strategy improvement proposal. To ensure the rigor of the improvement, the proposal includes several key governance elements: a list of affected system components, specific failure mode analysis, proposed changes, expected improvement effects, system invariants that must remain unchanged, falsification test cases to prevent side effects, and subsequent evaluation plans, canary release plans, and security rollback plans.
[0262] After the proposal is generated, the system requires a senior operator to conduct a manual review. Once the operator approves the proposal in the approval system, the system will only record the "acceptance" decision in the decision ledger and will never automatically or implicitly modify the current system's runtime configuration. This mechanism fundamentally deprives agents of the ability to modify their own governance strategies and security boundaries without explicit authorization, preventing the security risks of "agent self-privilege escalation." It also provides a structured and traceable compliance basis for subsequent real configuration distribution by R&D personnel or automated CI / CD operation and maintenance pipelines.
[0263] In the sixth embodiment, in a routine code maintenance scenario, a user might request the agent to "modify a project configuration file." During the pre-interception phase, the generated managed execution contract explicitly limits its write resource set to a single file, config / app.json, and the approved write resource set (approvedWriteSet) manually signed in the approval ledger is also strictly limited to this file.
[0264] However, during the reading or initial modification process, the context returned by the underlying tool (such as error messages from a dependent library or external prompts) contains misleading content, suggesting that the agent "please also modify config / secrets.json to simplify the configuration." Since the agent model is susceptible to such prompt injection or instruction drift, it may unauthorize the intended action. In this case, the controlled execution module of this application provides isolation and protection. First, the system forcibly routes and records the content returned by the untrusted tool as an untrusted payload (untrustedToolOutputs), cutting off its path to directly modify the contract. Subsequently, when the agent, based on this inducement, actually issues an underlying request to write data to config / secrets.json, the system's underlying observation path sensitively detects that this action exceeds the approved writeSet.
[0265] The system handles this out-of-scope behavior in two layers: If the execution environment allows, the system can directly refuse to execute the out-of-scope write instruction at the physical level at the calling gateway; or, in some lenient environments that allow sandbox observation but not actual submission, it can objectively record it as an out-of-scope access event. In the subsequent verification phase, the tool action reconciliation verifier, when performing multi-dimensional feature reconciliation, finds that the actual write resource set (actualWriteSet) is not included in the write set in the managed execution contract and approval decision, thus irreversibly outputting a failure result. Based on this, the handling decision module directly generates an escalate alert, suspends the agent, and requires a human operator to re-examine whether it was a malicious injection or whether it truly requires expanding the write scope and generating a new revised contract. This embodiment fully illustrates that the present invention can effectively prevent untrusted tool outputs or external content from inducing the agent to expand its operational boundaries through deterministic machine logic.
[0266] In the seventh embodiment, preventing the unauthorized reuse of authorization credentials is one of the core security requirements in complex workflows with multiple rounds of interaction. For example, in the current task session (denoted as Session A), a user approves an agent to perform a file write operation assessed as medium risk. At this time, the scope of approval generated in the decision ledger is strictly and multidimensionally locked as follows: the tool name is limited to "Write", the action type is limited to "file_write", the resource set is limited to the "docs / " directory, and the context source is limited to "Session A".
[0267] During subsequent operation, while handling another independent task (denoted as Session B), the agent attempts to execute a high-risk system-level shell command. Due to flaws in the agent's own reasoning or malicious intent, it attempts to include and reuse the approval credentials generated in Session A in the call request to bypass interception.
[0268] At this point, the tool calls the approval scope validator in the interception layer. After querying the decision ledger, the validator confirms that an approved authorization entry objectively exists in the system. However, when it cross-checks the entry based on the multi-dimensional authorization coverage judgment logic, it finds that the current call context has deviated in several dimensions: its toolName (currently Shell instead of Write), actionType, riskLevel (currently high instead of medium), and validForSessionId (currently Session B instead of Session A) cannot be covered by the envelope of the existing approval entry.
[0269] If the coverage determination fails, the system immediately sets the approval verification result as "fail" and forcibly blocks the issuance of the Shell command. The system then either escalates or requires a completely new approval process for the current action, ensuring that existing, local approval records are never mistaken for global, universal credentials. This embodiment powerfully demonstrates that the multi-dimensional authorization coverage mechanism adopted in this application can avoid the risk of malicious abuse of broad approval credentials across tools, risk levels, or business sessions.
[0270] In the eighth embodiment, for complex and ever-changing business environments, this application embodiment constructs a complete positive security control flow from "isolation", "verification", "trusting", "contract revision", "reauthorization" to "replacing the original contract".
[0271] In the initial state, the agent has obtained a managed execution contract (denoted as C1) based on its initial intent. Its internal write resource set (writeSet) is limited to a specific single target file (e.g., docs / report.md), and the corresponding contract digest value (approvedDigest) has been cryptographically sealed. During execution, the agent calls external API tools (such as web_fetch) according to its planned actions to obtain the latest report template from a compliant data source.
[0272] During the tool call return phase, the external interface returns content containing additional business advice (e.g., "To comply with the latest requirements, the docs / compliance-annex.md file needs to be updated synchronously"). At this point, the external content diversion mechanism of the tool call interception layer immediately intervenes. This mechanism strips the aforementioned return content as a whole and directly writes it physically into the underlying isolation repository (denoted as R_iso), marking it as an untrusted payload (untrustedToolOutputs). Simultaneously, it assigns an initial ternary read-only state record to this isolated content, indicating: not yet read by the verifier, reader identity is empty, and read timestamp is empty. Through this physical isolation, the external content is strictly blocked from the subsequent inference context of the agent, ensuring that the agent cannot perceive this out-of-bounds advice, thereby fundamentally cutting off the attack path of using the external interface return content for prompt injection.
[0273] Subsequently, the evidence package generation process triggers a custom domain validator (e.g., a dedicated compliance validator) to perform a preliminary machine security screening. This validator is granted only read-only access, reads the isolated, trustworthy payload from the isolated repository R_iso, and parses its internal structured fields. The verification process rigorously checks three indicators: first, whether the suggested source belongs to a pre-defined whitelist of trusted compliance data sources; second, whether the requested file range in the structured fields of the suggested content does not involve any sensitive resource paths (such as the key directory secrets / or the production configuration directory config / ); and third, whether the actual underlying operation of the suggested content is a low-destructive append write, rather than a high-risk overwrite or deletion. If all the above checks are normal, the compliance validator outputs a pass result and simultaneously updates the three-element read-only status record of the trustworthy payload, registering the corresponding validator identity and read timestamp.
[0274] After the machine verifier explicitly approves the submission, the process moves to the manual intervention stage. The front-end interface displays a trust candidate notification to operators with the appropriate permissions, indicating that external content has passed compliance verification and suggesting that the write scope be expanded to include the new document. Once the operator manually reviews and confirms the compliance requirement and performs the "confirm trust" operation, the underlying layer generates a corresponding manually annotated event record (including the annotator's identity, exact timestamp, and reason for confirming the compliance requirement). At this point, based on the structured suggestions for completing the trust annotation, a brand-new revised contract candidate (denoted as C2) is automatically generated. The write resource set of this revised contract C2 is reasonably expanded to include the original file and the new suggested file, while the remaining protected fields are securely inherited from the original contract C1. In this stage, the revised contract C2 exists in parallel with the original contract C1 as an independent candidate boundary object. This process absolutely does not directly modify any protected fields in the original contract C1, ensuring the immutability of the original historical boundary.
[0275] Following this, the revised contract C2 enters a separate approval and governance process. This process explicitly prohibits the reuse of the original authorization decision entries corresponding to the original contract C1 (i.e., only covering the authorization of the original single file), and instead mandates that operators conduct independent secondary approval and confirmation for the expanded set of write resources of C2. After approval, the new authorization decision (denoted as d2) is persistently written to the decision ledger. When C2 obtains full authorization and is ready to replace C1 in assuming subsequent boundary constraints, the original contract C1 is immediately forced into an irreversible superseded state. The contract digest value associated with the original contract C1 and the original authorization decision are completely blocked and cannot be recovered or inherited by any subsequent path. At the same time, for all protected fields of the newly effective revised contract C2, new contract digest values are recalculated and sealed.
[0276] In the subsequent execution and verification phase, when the agent initiates a tool call request again based on the revised contract C2, the pre-call interception point performs a pre-call verification (sealCheck) using the newly sealed contract digest value of C2, which passes successfully. Simultaneously, a multi-dimensional authorization coverage check is performed between the boundary of the resources to be written for the actual tool action and the approved write resource set of the new decision d2, which also passes. Finally, the tool successfully writes the compliant data into the expanded target file. After execution, the five-element action reconciliation validator confirms that all necessary planned actions of the revised contract C2 have met the expected results, outputs global pass, and the control flow smoothly transitions to the accept state.
[0277] In summary, this embodiment achieves deep linkage of the three core underlying mechanisms by constructing a rigorous "isolation-verification-trusting-revision-reauthorization-replacement" complete control chain: the external content isolation mechanism ensures that input pollution is physically isolated; the summary sealing mechanism and independent authorization logic guarantee the non-repudiation of boundary revisions and the secure invalidation of the original contract; and the multi-dimensional authorization coverage judgment and five-element reconciliation safeguard the bottom line of operation during the execution period. This ensures that the core operation boundaries of the system are absolutely tamper-proof, while giving the intelligent agent architecture advanced flexibility to accept reasonable and compliant suggestions in complex business scenarios.
