Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full burden and discloses nothing: it does not say whether the tool is read-only, whether it returns a prompt template or generated content, whether it writes anything, or what happens with the "edge-case handling" it advertises. The mention of an included "complete prompt, usage guide, and edge-case handling" hints at delivered artifacts but never explains their form.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
