Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. 'Restore' implies a state-changing mutation, but nothing is said about reversibility, idempotency, batch limits, side effects, or what happens if a product is already unarchived. This mirrors the gap seen in mutation tools with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
