Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool deletes and saves, which implies a destructive, persistent mutation. However, it doesn't mention permissions required, whether deletion is reversible, what happens to associated data, error conditions, or confirmation prompts. For a destructive operation with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
