Report #22507

[synthesis] Agent selects wrong or overlapping tools due to context overload from massive tool catalogs

Dynamically filter the available tool list based on the current sub-task. Use a router agent or RAG over tool schemas to expose only 3-5 relevant tools per step, rather than the entire catalog.

Journey Context:
Function calling performance degrades as the number of functions increases. The model's attention is spread across all tool descriptions, leading to confusion between similar tools \(e.g., search\_file vs grep\_file\). The tradeoff is architectural complexity \(adding a tool router\) vs. execution accuracy. Accuracy wins because a wrong tool call derails the entire reasoning chain.
