Fixlight

With a single tool there is no possibility of misselection; the tool's scope (scan one public URL for accessibility issues) is clearly stated and cannot be confused with anything else.

The name scan_url follows a clean verb_noun convention and clearly signals the action and target. There is only one tool, so no cross-tool pattern can be established or violated, which caps the meaningful ceiling slightly.

A one-tool server is thin by the rubric's standards; it is tightly scoped to a single purpose, but users may reasonably expect related operations (e.g. fix guidance lookup or batch scanning) to live alongside it.

The tool covers the core scan-and-report workflow and sets expectations about limits honestly, but there is no operation to scan multiple URLs, retrieve structured detail per finding, or follow up on fixes, leaving notable gaps for agents building a remediation loop.
