A general instruction to take action is too broad a contract for a tool your AI agent can call.

Replace universal action tools with narrow operations whose business purpose, inputs, effects, and failure behavior are clear.

Before execution, software should verify identity, permission, current business conditions, and whether the request is a duplicate.

Exercise a catalogue of invalid, stale, and uncertain cases. Show the operator what a rejected operation means and how it can be resolved.

Version the tool's meaning as well as its fields. A short contract card makes handover and later changes easier to review without relying on model judgment alone.
