Report #41983

[agent\_craft] Static tool registration exhausts context window and confuses agent with irrelevant schemas

Implement retrieval-augmented tool selection: embed the user query and fetch only the top-K relevant tool schemas from a vector store before the LLM call. Inject only these K schemas into the 'tools' parameter, not the full registry.

Journey Context:
We started with 50\+ tools hardcoded in the system prompt; the model hallucinated arguments for wrong tools because the signal-to-noise ratio collapsed. Truncating the list manually per workflow was brittle. The breakthrough was treating tool definitions like a dynamic library: the agent retrieves contextually relevant tools, similar to the Gorilla paper's approach for API retrieval. This reduced token usage by 70% and eliminated cross-tool hallucination in multi-turn sessions.
