Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of disclosing side effects. It reveals the operation writes by 'resaving resources', which implies modification of project files, and adds the version constraint. However, it does not mention that this may touch many files or other potential side effects like UID reassignment or irreversibility.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
