Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full behavioral burden. It communicates a read-only intent via 'get' and specifies scope (all channels) and content (patterns, start times), which separates it from mutating siblings. However, it does not explicitly state non-destructiveness, session requirements, or edge-case behavior, leaving the safety profile implicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
