Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. However, it only says 'from GitHub', hinting at an external API, but fails to mention whether this is a read-only operation, any rate limiting, or the format of the response. The agent has no information about the tool's side effects or dependencies.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
