Embodiments automate software discovery and delivery by decoupling repository understanding from change implementation. To aid the product- and technical-discovery phases of the SDLC, a large language model parses source code to produce human-readable technical documentation stored in a documentation store and machine-readable representations comprising vector embeddings linked in a graph store.

An LLM identifies affected subsystems using graph and similarity queries, composes structured prompts, and conditions automated code transformation tools; communicated through a machine-to-machine orchestration layer (e.g., a Model Context Protocol (MCP) gateway); to generate candidate artifacts. Artifacts are validated by policy gates and packaged as a reviewable change record with documentation, embedding, and graph updates staged in a pre-deployment overlay; upon promotion, the system atomically commits the staged updates. Telemetry from review and deployment informs subsequent planning.
