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 performs a deletion, implying a destructive mutation, but lacks critical details such as whether deletion is permanent, requires specific permissions, has side effects (e.g., affecting associated data), or provides confirmation. This is inadequate for a mutation tool with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
