Senior interview question
Your logs show most bad tool calls go to one tool. What do you do?
Model answer
Improve its description and examples, fine-tune if needed, and if it's still misused, change the tool: simpler parameters or a narrower purpose.
Also look at the tool-use distribution and ablate: if removing a tool doesn't hurt, remove it. Then rerun the test harness on every change.
