Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of disclosing the destructive nature of the tool. It does clearly say 'Delete', which signals that the webhook action will be removed, but it adds little beyond that: no mention of irreversibility, cascading effects on the form, cached data, or response behavior. It is honest but minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
