Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral disclosure burden. It only states 'List visible projects' and discloses nothing about return shape, pagination, sorting, or the meaning of 'visible.' There is no mention of side effects or permissions, though the listing action itself is likely read-only.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
