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. 'Initialize' implies a creation/mutation operation, but the description doesn't mention what gets created (e.g., .git directory), whether it's idempotent, what happens if a repository already exists, or any permission requirements. This leaves significant behavioral gaps for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
