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. It states 'List merge requests', implying a read-only operation, but doesn't specify permissions, rate limits, pagination, or what data is returned. This is inadequate for a tool with parameters and no output schema, as critical behavioral traits are missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
