Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It indicates a save operation (non-destructive in typical DAW context) but fails to disclose any side effects, permissions, limits on number of snapshots, or whether it overwrites existing snapshots. The term 'snapshot' implies safe state capture, but important behavioral details are missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
