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. However, it merely says 'Submit time entries to Unanet' without revealing what happens upon submission, such as whether it is irreversible, requires prior approval, or affects existing records. This is a significant gap for a mutation tool, as the agent cannot assess potential side effects or required permissions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
