Report #79595

[agent\_craft] Agent passes on all available tool schemas to the LLM on every turn, consuming context and confusing the model

Implement a tool router. Send only the schemas of tools relevant to the current sub-task to the LLM, rather than the entire toolbox. Use a lightweight classifier or the LLM itself to select the toolset before the main reasoning step.

Journey Context:
Passing 50 tool schemas consumes thousands of tokens and degrades the LLM's ability to select the right tool \(the 'needle in a haystack' problem for function calling\). By routing to a subset of tools \(e.g., 'file system tools' vs 'web search tools'\), you drastically reduce context usage and improve tool selection accuracy. The cost is an extra routing step, but it pays off in reduced errors and token savings.
