Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing side effects, permissions, or irreversibility. The phrase 'Update' implies mutation, but there is no mention of what changes are made, whether they are reversible, or required scopes. This is a significant transparency gap for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
