Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full behavioral burden and fails: it never says whether output goes to the 'path' on disk or is returned inline, whether it is read-only, whether it overwrites an existing file, or what 'SVG-like' means versus real SVG. Nothing beyond a restated purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
