Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate a non-read-only, non-idempotent, potentially open-world operation. The description adds only the SCRIPTING_ENABLED prerequisite, but does not explain behavioral traits like side effects, data modification, or failure behavior, which are important for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
