Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Adds substantial context beyond annotations: attacks run against a live target, the test:run scope is required, results are asynchronous ('validating'), and 'still_broken' can mean the re-run could not confirm the fix. These details materially affect safe invocation of a destructive/open-world operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
