--- name: browser-tools description: Use this skill when the user asks to test, verify, interact with, or automate web pages and browsers. Trigger for requests involving Chrome automation, browser testing, web scraping, screenshot capture, element selection, or checking web applications. Also trigger when user mentions "browser tools" explicitly. allowed-tools: Bash(browser-start:*), Bash(browser-nav:*), Bash(browser-eval:*), Bash(browser-screenshot:*), Bash(browser-pick:*), Bash(browser-cookies:*), Bash(browser-console:*), Read, Read(/tmp/screenshot*), Glob --- # Browser Tools Chrome DevTools Protocol automation for agent-assisted web testing and interaction. Uses Chrome running on `:9222` with remote debugging. ## Prerequisites **Run `/browser-tools:setup` once after plugin installation** - This installs dependencies and creates global symlinks for all browser scripts. ## Usage When user asks to test, verify, or interact with web pages using browser tools: 1. **Start Chrome** - Launch with debugging enabled 2. **Navigate & interact** - Use scripts to navigate, evaluate JS, take screenshots 3. **Return results** - Show output/screenshots to user **IMPORTANT**: Use command names directly (e.g., `browser-start`), NOT full paths (e.g., `~/bin/browser-start`). Commands are in PATH after setup. ## Available Scripts All scripts located in `skills/browser-tools/scripts/`: ### browser-start By default use the persistent profile at `/tmp/chrome-profile-browser-tools`. ```bash browser-start --profile # Persistent profile browser-start # Fresh profile ``` Launch Chrome with remote debugging on port 9222. Use `--profile` to maintain login state between sessions. ### browser-nav ```bash browser-nav https://example.com browser-nav https://example.com --new ``` Navigate to URLs. Use `--new` to open in new tab instead of current tab. ### browser-eval ```bash browser-eval 'document.title' browser-eval 'document.querySelectorAll("a").length' browser-eval 'Array.from(document.querySelectorAll("h1")).map(h => h.textContent)' ``` Execute JavaScript in active tab. Runs in async context. Use for: - Extract data from pages - Inspect page state - Manipulate DOM - Test page functionality ### browser-screenshot ```bash browser-screenshot ``` Capture current viewport, returns temp file path. Use Read tool to show screenshot to user. ### browser-pick ```bash browser-pick # Uses default message "Select element(s)" browser-pick "Select the submit button" ``` **Interactive element picker** - Launches UI overlay for user to click and select elements. Returns element details (tag, id, class, text, html, parent hierarchy). Message parameter is optional. Use when: - User says "click that button" or "extract those items" - Need specific selectors but page structure is unclear - User wants to identify elements visually Controls: - Click to select single element - Cmd/Ctrl+Click for multiple selections - Enter to finish (when multiple selected) - ESC to cancel ### browser-console ```bash browser-console # Stream logs until Ctrl+C or kill browser-console --url http://... # Navigate and exit after load browser-console --url http://... --no-exit # Navigate then keep streaming browser-console --level error,warn # Filter by log level ``` Capture console logs (log, warn, error, info, debug) from Chrome. Includes stack traces for errors and page errors. **Modes:** - **Streaming** (default): Captures logs until process is killed. Best for workflow monitoring. - **Navigation** (`--url`): Navigates to URL and exits after page load. Captures logs during page initialization. **Claude Code usage:** ```bash # Page load logs - auto-exits after load browser-console --url http://localhost:3000 # Workflow monitoring - run in background, kill when done browser-console & browser-nav http://localhost:3000 browser-eval "triggerSomeAction()" # Check logs via BashOutput, kill via KillShell ``` ### browser-cookies ```bash browser-cookies ``` Display all cookies for current tab (domain, path, httpOnly, secure flags). Use for debugging auth issues. ## Workflow Examples ### Test dev server feature ```bash # Start browser with persistent profile browser-start --profile # Navigate to dev server browser-nav http://localhost:3000 # Test functionality browser-eval 'document.querySelector("#new-feature").textContent' # Take screenshot SCREENSHOT=$(browser-screenshot) # Then use Read tool to show screenshot at $SCREENSHOT path ``` ### Debug authentication ```bash browser-start --profile browser-nav https://app.example.com/login browser-cookies ``` ### Extract data from page ```bash browser-start browser-nav https://example.com browser-eval 'Array.from(document.querySelectorAll(".product")).map(p => ({name: p.querySelector(".title").textContent, price: p.querySelector(".price").textContent}))' ``` ## Important Notes - **Chrome required** - Scripts use `google-chrome` binary - **Port 9222** - Chrome runs with `--remote-debugging-port=9222` - **Profile location** - `/tmp/chrome-profile-browser-tools` when using `--profile` - **Temp screenshots** - Screenshots saved to OS temp directory - **Dependencies** - Requires `chrome-remote-interface` (installed via `/browser-tools:setup`) - **Error handling** - If scripts fail, check Chrome is running and port 9222 is available --- Source attribution: David-Li0406 Original project: https://github.com/David-Li0406/meta-skill-evloving/blob/ca3a335628981df10c36e00cb9850df2c247ab9a/skill-flow/data/skills-refined-36k/skillsmp/browser-tools/SKILL.md License: Apache-2.0 License information: https://www.apache.org/licenses/LICENSE-2.0 Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice Apache License Version 2.0, January 2004 http://www.apache.org/licenses/ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 1.
