The invention relates to the technical field of multi-agent
collaboration, in particular to a task execution method and
system based on multi-agent
collaboration, and the method comprises the steps: carrying out the semantic analysis and multi-
granularity decomposition of a user task instruction, generating a subtask dependence structure, and storing the subtask dependence structure into a dynamic task
pool; performing collaborative planning and rehearsal execution on the to-be-executed subtasks, generating context snapshots, executing Push, and writing the Push into a historical state stack; retrieving an evidence chain based on the
domain knowledge base and extracting a fact triple set, performing consistency comparison based on structured evidence triples on the candidate reasoning paths, and outputting conflict confidence and consistency scores; when the consistency
score is lower than a threshold value, triggering a
projectile stack, physically clearing wrong
branch intermediate data, recovering a historical context, injecting a
negative feedback prompt to generate a new
inference branch, and returning to continue rehearsal execution; if the
verification is passed, outputting a result and entering a next subtask; therefore, the
controllability and auditing performance of multi-agent cooperative task execution are improved.
