Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral transparency. It only states the core action without disclosing any side effects (e.g., replacing current project, closing unsaved changes, error handling for missing files). This is a significant gap for a potentially destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
