Check an HTML page, blog post or tool page before it goes live. A local, keyless script reports exact, line-numbered problems: missing or mismatched head tags, heading and link issues, images without alt text, broken schema, FAQ or breadcrumb data that disagrees with the page, duplicated blocks, and your own house rules. Your agent fixes what it finds and re-runs to confirm. A checklist, not a ranking score. Nothing is uploaded.
Check HTML files for the markup problems that most often slip into hand-written pages, templates and email markup: unclosed and mismatched tags, duplicate ids, images without alt text, missing or empty titles, a missing lang attribute or doctype, deprecated tags, and links without a target. Runs fully offline with Python's standard library, reports every finding with a file and line number, and never copies attribute values into its reports.
Turn URLs and saved-login notes into an ALIVE / DEAD / UNDETERMINED table; handles SPA 200s, 403 blocks, soft 404s.
