Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description asserts a mutation operation ('Find and replace...'), but annotations declare readOnlyHint=true and destructiveHint=false, which is a direct contradiction. The description does not reconcile this, leaving the agent with inconsistent signals about the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
