Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide basic hints (non-readonly, non-destructive, non-idempotent, open-world), but the description adds minimal behavioral context. The 'runManually' name implies triggering an action, and POST method suggests mutation, but the description doesn't clarify what happens (e.g., whether this executes a scheduled task immediately, returns execution results, affects schedule status). No rate limits, authentication needs, or side effects are described beyond what annotations imply.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
