Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It discloses a key behavioral trait: the user will be added as team lead, which is a non-obvious side effect. However, it doesn't mention permissions, reversibility, or any return details, so it is informative but not comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
