Tools and MCPs

An agent has two tools with nearly identical descriptions and starts calling the wrong one intermittently. What's the actual bug?

Show answer and explanation

Answer: B — The tool descriptions overlap — the model routes purely on name/description/schema

Tool descriptions function as prompts. The fix is sharpening each description so their 'use this when…' conditions are mutually exclusive — not a model or temperature problem.
