Report #76795

[agent\_craft] Agent system prompt includes every possible tool schema, confusing the router and increasing hallucination

Implement a two-stage router: first, use a cheap/fast model or semantic search to select the top 3-5 relevant tools for the user's intent, then construct the context with only those tool schemas.

Journey Context:
Providing 50\+ tool schemas in the prompt drastically degrades the LLM's ability to select the right tool and increases cost/latency. The model gets confused by similar tool names \(e.g., get\_user vs search\_users\). By dynamically routing and injecting only the relevant tools, you improve accuracy and reduce token usage. The tradeoff is adding a routing step, but a fast embedding search or small LLM call is cheaper than a massive context window.
