Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It does disclose an important safety trait: it shows status "without publishing anything." It does not cover permissions, whether local Git state is modified, rate limits, or what the response contains beyond a high-level description.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
