Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. While 'Update' implies a mutation, the description lacks critical details: it doesn't specify if this requires special permissions, whether updates are atomic or partial, what happens on errors (e.g., partial failures), rate limits, or response format. For a batch mutation tool with zero annotation coverage, this is a significant gap in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
