Front-End Checklist

Runs a non-exhaustive static heuristic review of pasted HTML, CSS, or JavaScript against multiple frontend best practices and returns prioritized issues, fix guidance, and suggestions for manual verification. Use it when the user requests a review, audit, or debugging of source code. An empty issue list means no provable static issue was found; it does not establish accessibility conformance or ru

Fetches a public HTTPS page and performs a non-exhaustive static review of its HTML, returning prioritized issues and fix guidance. Use it when the user requests an audit of a deployed public page.

Use it when the user requests a check of a specific rule or a proposed fix. Results do not establish rendered-state or runtime conformance.

Returns step-by-step remediation guidance and priority for one named frontend rule. Use it when the user requests implementation or fix instructions for a known issue. Optional codeSnippet provides context; the tool does not edit files or apply changes.
