Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. While 'List all issues' implies a read-only operation, it doesn't disclose important behavioral traits like pagination, sorting, filtering capabilities, rate limits, authentication requirements, or what 'all' means in practice (e.g., archived issues included?). The description is minimal and leaves key operational questions unanswered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
