Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations, so the description carries the full load. It discloses helpful side effects (auto-install dependencies, automatic DB_PATH injection) and the create-or-update dual behavior, but omits permission needs, error modes, and whether the update replaces the whole app or merges. Partial behavioral coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
