Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully disclose behavioral traits. It states the core action and return value, but omits side effects (e.g., whether recording state is cleared), error conditions (e.g., calling when no recording is active), or any safety profile. This is a state-changing operation and needs more detail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
