Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. While 'fetches' implies a read operation, it doesn't disclose important behavioral traits like authentication requirements, rate limits, pagination behavior (implied by limit/offset parameters but not explained), error conditions, or what 'all projects' means in terms of scope or permissions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
