Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It mentions 'Создать/обновить' (create/update), implying a mutation, but doesn't disclose behavioral traits such as permissions required, whether it's idempotent, what happens on conflicts, or output format. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
