Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. 'Add or update' hints at upsert semantics, but it says nothing about permissions, whether an existing resolution is overwritten, or what happens on conflict — critical for a mutation tool with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
