Report #12267

[agent\_craft] Agent selects the wrong tool for the task \(e.g., searching local code instead of the web\)

Make tool descriptions mutually exclusive by explicitly stating what the tool does NOT do, and include 2-3 examples of appropriate vs. inappropriate use cases in the description.

Journey Context:
LLMs route actions based heavily on tool descriptions. If 'search\_code' and 'search\_web' both just say 'Searches for information', the agent will guess. Explicitly stating 'Searches the local codebase. DO NOT use for general programming questions or documentation lookup; use search\_web instead' creates clear boundaries. The small token investment in the tool description pays massive dividends in routing accuracy.
