| description | Render and view webpages using a headless browser (Playwright) to fetch JS-rendered HTML, extract visible text, and optionally save full-page screenshots. Use when a user asks to “无头浏览器打开/查看网页”, needs the rendered DOM instead of raw curl HTML, or wants a screenshot of a page. |
Headless Web Viewer
Run
Render + save artifacts
node .claude/skills/headless-web-viewer/scripts/render_url_playwright.mjs '<URL>' \
--out-html /tmp/page.html \
--out-text /tmp/page.txt \
--out-screenshot /tmp/page.png
Print to stdout (pipe-friendly)
node .claude/skills/headless-web-viewer/scripts/render_url_playwright.mjs '<URL>' --print text
Dependencies
This skill requires Playwright in the environment where it runs.
Option A (recommended for global use, no browser download)
Install Playwright Core and use system Chrome:
npm i -D playwright-core
Run with --channel chrome.
Option B (bundled browsers)
npm i -D playwright
npx playwright install
Do not auto-install dependencies unless the user asks.
Tips
- If a page hangs on
networkidle, retry with --wait-until domcontentloaded.
- If a page blocks headless Chromium, try setting
--user-agent to a realistic UA.
