Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already communicate that this is mutating, idempotent, and non-destructive. The description adds the behavioral detail that only files locked by this MCP connector are affected, which is useful context, but it does not address error behavior or lock ownership beyond that.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
