Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full burden of behavioral disclosure. The verb '查看' (view) implies a read-only operation, but the description does not explicitly state that there are no side effects, what permissions are required, or whether the tool modifies anything. It does disclose the output content (workspace existence, hash, file list, parent/child), but omits other behavioral traits such as error conditions or rate limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
