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 operation, the description doesn't address critical behavioral aspects: whether this requires specific permissions, what happens if the object doesn't exist, whether updates are partial or complete, if there are rate limits, or what the response contains. For a mutation tool with zero annotation coverage, this represents a significant transparency gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
