[research] Agent selects the wrong tool despite having the correct available tools and instructions

Isolate tool selection as a specific eval step by testing the LLM with only the tool-choice decision, scoring it on precision/recall of tool selection against a dataset of historical queries, before integrating it into the full loop.

Journey Context:
When an agent fails, developers often blame the tool execution or the prompt. But often the root cause is semantic confusion in tool selection \(e.g., choosing search\_files instead of read\_file\). Evaluating the entire loop makes it hard to isolate this. By extracting just the routing decision, you can fine-tune or adjust tool descriptions specifically to improve selection accuracy without touching the rest of the logic.
