Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It mentions the 100-record limit, which is useful behavioral context. However, it lacks critical details: authentication requirements, rate limits, error handling (e.g., what happens if some IDs are invalid), response format specifics, or whether it's idempotent. For a batch operation with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
