Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full responsibility for disclosing behavioral traits. It only states 'Update a team' with no mention of whether this is a partial update, whether unspecified fields are cleared, or any side effects, permissions, or error conditions. This is a serious 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.
