Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It states 'Delete' (destructive action) but fails to mention the critical allowalteration parameter that must be true for execution. This omission could lead to failed invocations. No other behavioral aspects (e.g., idempotency, consequences) are described.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
