Report #74066

[agent\_craft] Agent is given dozens of tool schemas in the system prompt, causing it to hallucinate parameters or select the wrong tool because definitions blur together

Implement a tool router: only inject the schemas for the 3-5 tools relevant to the current sub-task into the immediate context, keeping the rest in a searchable tool registry.

Journey Context:
Every tool definition consumes tokens and adds cognitive load. Research on API-calling LLMs shows that tool-calling accuracy drops significantly as the number of available tools increases. A two-step process—first route to a relevant tool subset, then call the tool—drastically improves accuracy and reduces prompt cost compared to injecting all tools at once.
