Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses that the tool replaces the body, is idempotent, and supports an optional expected revision, which adds behavioral context beyond the raw annotations. However, it does not explain what happens on a revision mismatch, whether the note must already exist, or the consequences of replacing the body. The idempotency hint is already in annotations, so the description adds only moderate value here.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
