What Tool Use practice should teach you
Good practice is not about recognising a keyword. It is about choosing the strongest architecture decision when several answers look plausible. Use this domain to practise these three habits:
- Define narrow, legible tool contracts with validated inputs.
- Handle retries, idempotency, permissions, and partial failure.
- Keep human approval around consequential side effects.
Common mistake
Equating a working tool call with a reliable workflow. Production tool design needs observability, safe failure behavior, and a clear owner for each side effect.
