Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool deletes an issue, implying a destructive mutation, but lacks critical details: it doesn't specify if deletion is permanent/reversible, what permissions are required, if there are side effects (e.g., cascading deletions), or what the response looks like (e.g., success/failure indicators). For a destructive tool, 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.
