Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden, yet it discloses nothing: not whether linking is idempotent, whether it mutates or replaces an existing link, whether it requires an active project, or what side effects occur. For a mutation tool with zero annotation coverage this is a complete gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
