Report #2358

[research] Agent selects the wrong tool or fails to select any tool when multiple are available

Log and observe the LLM's tool selection probability/entropy alongside the final tool call. If entropy is high, flag the trace for review and improve the tool's description.

Journey Context:
Agents fail tool selection not because of bad logic, but because of ambiguous tool descriptions. If an agent hesitates between 'search\_files' and 'read\_file', it's a description problem. Observing selection confidence \(or just the frequency of tool-switching in traces\) pinpoints exactly which tool descriptions need rewriting.
