Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description takes on full burden. It discloses it's a thin wrapper around share_map, mentions the 30-day TTL, and specifies the return JSON fields. However, it doesn't detail side effects, auth needs, or error conditions, leaving minor gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
