    • Add missing Open Graph blocks to contact.html to ensure link unfurling works on Slack and LinkedIn.
    • Shorten the title tag in about.html to prevent truncation in mobile share sheets.

    About this skill

    Differentiation (read this first) Unlike seo-meta-tags-generator (which writes titles/descriptions/schema) or schema rich-results audits (JSON-LD eligibility), this pack audits share-preview readiness: Open Graph (og:*) and Twitter Card (twitter:*) tags on saved HTML — so LinkedIn / X / Slack / iMessage unfurls do not ship broken. It never invents tags and never claims CTR or engagement lift.

    Sample output (offline dry-run on the included Harborline Tools HTML — 2026-10-16)

    pages=4 | PASS=1 | WARN=1 | FAIL=2
    URLStatusNotes
    /guides/dock-cleatsPASSog:* + twitter:card present; titles aligned
    /compare/anchor-clamp-pro-vs-standardWARN<title> 95>60; og:title ≠ title; empty share-image alt
    /pricing/anchor-clamp-proFAILmissing og:image; missing twitter:card
    /faq/dock-hardwareFAILog:image is relative (not absolute http/https)

    The problem Marketers paste a landing URL into Slack or LinkedIn and the preview shows the wrong title, no image, or a truncated headline. Meta-tag generators write copy; they do not QA whether the tags you already shipped will unfurl cleanly. Schema audits and citation-freshness packs do not cover this gap.

    What it does

    • Parses saved HTML for og:title, og:description, og:image, og:url, og:type, twitter:card, twitter:title, twitter:description, twitter:image
    • Flags FAIL for missing critical tags or non-absolute og:image
    • Flags WARN for title truncation risk (>60), title≠og:title drift, missing og:url/type, empty share-image alt
    • Writes CSV + Markdown; stdout one-liner for agents/CI
    • Offline-first, stdlib Python only — no paid APIs, no network in default mode

    Why this beats prompting it yourself Same PASS/WARN/FAIL rules every run. Offline works unplugged. Never invents tags. CSV your agent can diff in CI before a campaign launch.

    Use cases

    • Pre-flight before posting a landing URL to LinkedIn / X / Slack / iMessage
    • Agency deliverable: "share preview audit" on client HTML exports
    • CI gate after a CMS template change that touches head tags

    Example session

    "Audit these landing pages for Open Graph + Twitter Card share-preview readiness." → pages=4 | PASS=1 | WARN=1 | FAIL=2 → Fix checklist: add absolute og:image + twitter:card on pricing; shorten compare title; fix FAQ relative image path
