Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden for a destructive operation. It says 'clear all' but never states whether the wipe is irreversible, whether it needs confirmation, or whether it affects the buffer read by vibeside_telemetry_get. The word 'cached' hints the data is transient, which is the only behavioral signal offered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
