Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It discloses that the call also creates a database, schema, and API key beyond the obvious project record, and that it is restricted to admin/super_admin – useful non-obvious context. However, it says nothing about reversibility, side-effect cleanup, failure modes, or whether the API key is returned in the response.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
