Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the annotations, which already indicate a non-read-only, non-destructive operation, the description discloses key behavioral details: re-fetching, re-snapshotting, re-scanning, rebuilding for code bundles, diffing, auto-drafting a changelog, submitting for admin review, keeping the live version serving until approval, and being a no-op if the source is unchanged. This gives the agent a thorough understanding of side effects and outcomes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
