Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations and no output schema, so the description carries the full burden and largely fails. The single useful disclosure is that the return includes a prompt, usage guide, and edge-case handling, which implies this is a static template-delivery tool rather than an analysis engine. It says nothing about what the tool does with the input, whether it generates anything new, or what the caller should expect back beyond those three named artifacts.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
