Report #9166

[agent\_craft] Agent selects wrong tool when multiple tools could satisfy the request \(e.g., 'search\_code' vs 'read\_file' for finding a function\)

Add explicit disambiguation lines in tool descriptions: 'Use read\_file when you need the full content of a specific file path. Use search\_code when you need to find files matching a pattern or containing specific text.'

Journey Context:
Ambiguity arises when tool capabilities overlap. Simply naming the tool 'read\_file' is insufficient; the description must explicitly contrast it with similar tools. This prevents the 'hammer looking for nails' problem where the model uses its most recent or favorite tool.
