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 It discloses several non-obvious traits (new key, unpublished, doesn't claim default, no chain pointer), giving the agent valuable expectations. It does not mention permissions or source-side effects, but for a clone operation, these are less critical.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
