Standalone Codex\notherwise uses the Lighthouse CLI plus native/manual screenshots; if no visual\ncapture path exists, stop before changing UI and report that visual regression\nverification is unavailable. This package does not auto-run unpinned registry\nMCP packages.\n\n**Method:** 3 mobile + 3 desktop runs per audit, averaged for reliability. After each code change, re-audit and visually verify the page with the configured MCP or the stated manual fallback.\n\n---\n\n## Setup\n\n1. **Parse URL** from `$ARGUMENTS`. If no URL, ask the user. Default: `http://localhost:3000`\n\n2. **Verify prerequisites:**\n ```bash\n lighthouse --version # CLI must be installed for the batched 3x3 protocol\n ```\n If lighthouse is missing: `npm install -g lighthouse`\n If runs fail with a chrome-launcher error or every metric comes back\n `NO_LCP`/null, no system Chrome exists — find a real Chrome/Chromium binary\n (Chrome for Testing, Playwright's `chromium-*` — NOT `chrome-headless-shell`,\n which produces NO_LCP) and export `CHROME_PATH=` before the loop.\n Record which binary was used; a before/after comparison is only clean when\n both sides ran the same binary.\n Check whether the user configured the chrome-devtools MCP. Do not install or\n auto-run an unpinned registry MCP on their behalf.\n\n3. **Create results directory:**\n ```bash\n mkdir -p \"$LIGHTHOUSE_DIR\"\n ```\n\n4. **Take baseline screenshots** before any changes:\n - `mcp__chrome-devtools__navigate_page` (type: \"url\", url: ``)\n - `mcp__chrome-devtools__take_screenshot`\n\n Describe the current layout, key elements, and visual state. This is your **visual baseline** — you will compare against it after every change to catch regressions.\n\n5. **Confirm with user:** Show the URL, confirm the dev server is running, ask if there are specific pages or routes to audit beyond the main URL.\n\n---\n\n## Audit Protocol\n\nEach audit consists of **3 mobile + 3 desktop runs**, averaged per category.\n\n### Run the audits\n\n```bash\n# Mobile runs (Lighthouse default is mobile)\nfor i in 1 2 3; do\n lighthouse \\\n --output=json \\\n --output-path=\"$LIGHTHOUSE_DIR/mobile-$i.json\" \\\n --chrome-flags=\"--headless --no-sandbox\" \\\n --only-categories=performance,accessibility,best-practices,seo \\\n --quiet \\\n 2>/dev/null\ndone\n\n# Desktop runs\nfor i in 1 2 3; do\n lighthouse \\\n --output=json \\\n --output-path=\"$LIGHTHOUSE_DIR/desktop-$i.json\" \\\n --chrome-flags=\"--headless --no-sandbox\" \\\n --preset=desktop \\\n --only-categories=performance,accessibility,best-practices,seo \\\n --quiet \\\n 2>/dev/null\ndone\n```\n\n### Extract scores\n\nFor each JSON result file:\n```bash\ncat \"$LIGHTHOUSE_DIR/mobile-1.json\" | \\\n jq '{\n performance: (.categories.performance.score * 100),\n accessibility: (.categories.accessibility.score * 100),\n bestPractices: (.categories[\"best-practices\"].score * 100),\n seo: (.categories.seo.score * 100)\n }'\n```\n\n### Compute averages\n\nAverage the 3 runs per category for both mobile and desktop. Report as:\n\n```\n## Audit Results\n\n| Category | Mobile (avg) | Desktop (avg) |\n|----------|-------------|---------------|\n| Performance | XX | XX |\n| Accessibility | XX | XX |\n| Best Practices | XX | XX |\n| SEO | XX | XX |\n```\n\n### Extract failing audits\n\nFrom the JSON, find specific audits that failed or scored poorly:\n```bash\ncat \"$LIGHTHOUSE_DIR/mobile-1.json\" | \\\n jq '.audits | to_entries[] | select(.value.score != null and .value.score < 0.9) | {id: .key, score: .value.score, title: .value.title, description: .value.displayValue}'\n```\n\nSort by impact (lowest scores first). These drive the improvement loop.\n\n---\n\n## Diagnose From the JSON, Not From a Narrative\n\nBefore planning any fix, re-derive the bottleneck from the report you just ran.\nPrior session notes, state files, and issue write-ups go stale and get root\ncauses wrong — treat them as hypotheses to check against the JSON, never as the\ndiagnosis.\n\n**Classify the perf gap first:**\n\n- **TBT high (hundreds of ms)** → main-thread problem. Long tasks, hydration,\n script execution. `mainthread-work-breakdown` and `long-tasks` tell you where.\n- **TBT low (~tens of ms) but LCP high under `throttlingMethod=simulate`** →\n bytes-on-critical-path problem, NOT execution. Lantern replays observed\n traffic over simulated slow 4G, so eager bytes inflate LCP even when the page\n is actually fast. Fixes that defer *execution* will not move this; only\n removing or lazy-loading *bytes* will.\n\nDo not read `mainthread-work-breakdown`'s total as \"blocking work before\npaint\" — it is the whole page load. TBT is the blocking measure.\n\n**For bytes-on-critical-path gaps, attribute before fixing:**\n\n```bash\njq '.audits[\"resource-summary\"].details.items[] | {resourceType, requestCount, transferSize}' \"$LIGHTHOUSE_DIR/mobile-1.json\"\njq '.audits[\"bootup-time\"].details.items[:5]' \"$LIGHTHOUSE_DIR/mobile-1.json\"\njq '.audits[\"network-requests\"].details.items | sort_by(-.transferSize)[:10] | .[] | {transferSize, resourceType, url}' \"$LIGHTHOUSE_DIR/mobile-1.json\"\n```\n\nFor a full attribution of a route's JS by package and app directory, and the\nmeasured fix ladder for bytes-on-critical-path gaps (AVIF, per-route CSS\nchunking, font subsetting with `unicode-range`, platform elements over client\nwidgets), use `~/.claude/skills/audit/references/performance-playbook.md` and\nits two harness scripts. If a hosted runner (PageSpeed Insights) reports \"the\npage stopped responding\" while local runs pass, the page runs WebGL on a\nsoftware renderer: reproduce with\n`--chrome-flags='--headless=new --disable-gpu --use-gl=angle --use-angle=swiftshader'`\nand gate the canvas on the renderer string (playbook rung 7).\n\nHunt for bytes that ship but do nothing: preloaded fonts no style consumes\n(a grep hit on the font file may be its own declaration — check for a real\nconsumer), and libraries a `next/dynamic` wrapper claims to defer while a\nsecond static import path pulls them in anyway. Verify eager-path claims\nagainst the build manifest (`.next/build-manifest.json` on Next.js), not\nagainst the wrapper's existence. A `next/dynamic({ssr:false})` component that\nrenders unconditionally still fetches its chunk at hydration — deferral only\npays when the render is conditional.\n\n---\n\n## Improvement Loop\n\n> **Autonomous mode:** to drive this loop turn-by-turn without re-prompting, set\n> `/goal mobile and desktop scores in all four categories meet their targets, or stop after 20 rounds`.\n> A goal evaluator (Haiku by default) reads the audit table after each turn and decides whether to continue.\n> See [/goal docs](https://code.claude.com/docs/en/goal).\n\n```\nLOOP until all scores >= 90 or user interrupts:\n\n 1. IDENTIFY the lowest-scoring category and its top failing audits\n - Read the Lighthouse audit details for specific recommendations\n - Cross-reference with the project's performance rules\n\n 2. PLAN one targeted fix\n - Focus on the highest-impact failing audit\n - One fix at a time — never batch multiple unrelated changes\n - Common fixes by audit:\n • render-blocking-resources → async/defer scripts, inline critical CSS\n • largest-contentful-paint → priority attribute, preload, optimize image\n • cumulative-layout-shift → explicit dimensions, font-display\n • unused-javascript → dynamic imports, code splitting\n • uses-responsive-images → srcSet + sizes, `next/image` (satus) or ``/`vite-imagetools` (novus), proper dimensions\n • uses-text-compression → verify gzip/brotli enabled\n • image-size-responsive → width/height attributes\n • unminified-javascript → check build config\n • dom-size → reduce DOM nodes, virtualize lists\n • third-party-summary → defer/lazy-load third-party scripts\n • font-display → font-display: swap or optional\n • offscreen-images → loading=\"lazy\" (NOT on above-fold/LCP images)\n\n 3. IMPLEMENT the fix\n - Edit the relevant source files\n - Keep changes minimal and focused\n\n 4. VERIFY BUILD\n - Run the project build to ensure no compilation errors\n - If TypeScript project: `tsc --noEmit` first\n\n 5. VISUAL REGRESSION CHECK\n - `mcp__chrome-devtools__navigate_page` to the same URL\n - `mcp__chrome-devtools__take_screenshot`\n - Compare against the baseline screenshot:\n • Layout intact? (same general structure, no collapsed/missing sections)\n • Content visible? (text, images, interactive elements still present)\n • Styling correct? (colors, spacing, typography not broken)\n • Functionality preserved? (interactive elements still look clickable)\n - If regression detected: REVERT the change immediately and try a different approach\n - Also check critical user flows if the change affects interactive elements:\n - `mcp__chrome-devtools__take_snapshot` (a11y tree — confirms interactive elements are present, returns `uid`s)\n - `mcp__chrome-devtools__take_screenshot` (visual verification)\n\n 6. RE-AUDIT\n - Run full audit protocol again (3 mobile + 3 desktop)\n - Compare against previous scores\n\n 7. LOG RESULTS\n - Append to `$LIGHTHOUSE_DIR/results.tsv`:\n round\tmobile_perf\tdesktop_perf\tmobile_a11y\tdesktop_a11y\tstatus\tdescription\n - Status: \"kept\" (scores improved), \"reverted\" (regression or no improvement)\n\n 8. REPORT\n - Show score delta: \"Performance: 72 → 85 (+13)\"\n - Show what was changed and why\n - Show the current failing audits for the next round\n - Every claimed delta needs BOTH sides measured on the SAME basis:\n • Bundle/byte savings: never quote a number from one build. Wipe the\n build output dir on both sides first — chunk dirs accumulate stale\n hashed files across builds, and a dirty-dir comparison can invert\n the sign of the result.\n • Never compare transfer bytes (from the Lighthouse JSON) against\n on-disk bytes — same basis or no claim.\n • A change measured worse gets reported worse, then reverted.\n\n 9. CONTINUE to next round\n```\n\n---\n\n## Visual Regression Protocol\n\nThis is the critical safety net. Performance changes MUST NOT break the UI.\n\n### After every code change:\n\n1. **Navigate:** `mcp__chrome-devtools__navigate_page` (type: \"url\", url: ``)\n2. **Screenshot:** `mcp__chrome-devtools__take_screenshot`\n3. **Compare** against baseline:\n - Is the page layout the same structure?\n - Are all visible elements still present?\n - Is text readable and properly styled?\n - Are images displaying correctly?\n - Are interactive elements (buttons, forms, nav) visually intact?\n\n### Regression = immediate revert\n\nIf any visual regression is detected:\n1. `git checkout -- ` to revert\n2. Log status as \"reverted (visual regression)\" in results.tsv\n3. Try an alternative approach to the same audit issue\n4. NEVER accept a performance improvement that breaks the UI\n\n### Multi-page checks\n\nIf the user specified multiple URLs/rou","tagline":"Lighthouse audit + improvement loop until targets met.
