Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states the action ('Resolve...to its ID') but does not disclose behavioral nuances such as whether this is a read-only operation, what happens if the slug is not found, or that the project parameter is required for disambiguation. The one-sentence description adds no context beyond the core purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
