Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden of behavioral disclosure. It implies a read-only listing of local bundled docs, but does not describe the return format, pagination, or whether any session/project state is required. For a zero-parameter list operation the behavior is simple, but the description remains minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
