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. It states the action is to 'unhide,' implying a mutation that changes visibility, but doesn't specify permissions required, whether it's reversible, rate limits, or what the output contains. The description is minimal and lacks critical behavioral context for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
