--- name: agent-browser description: Headless browser automation CLI optimized for AI agents with accessibility tree snapshots and ref-based element selection metadata: {"clawdbot":{"emoji":"🌐","requires":{"commands":["agent-browser"]},"homepage":"https://github.com/vercel-labs/agent-browser"}} --- # Agent Browser Skill Fast browser automation using accessibility tree snapshots with refs for deterministic element selection. ## Why Use This Over Built-in Browser Tool **Use agent-browser when:** - Automating multi-step workflows - Need deterministic element selection - Performance is critical - Working with complex SPAs - Need session isolation **Use built-in browser tool when:** - Need screenshots/PDFs for analysis - Visual inspection required - Browser extension integration needed ## Core Workflow ```bash # 1. Navigate and snapshot agent-browser open https://example.com agent-browser snapshot -i --json # 2. Parse refs from JSON, then interact agent-browser click @e2 agent-browser fill @e3 "text" # 3. Re-snapshot after page changes agent-browser snapshot -i --json ``` ## Key Commands ### Navigation ```bash agent-browser open <url> agent-browser back | forward | reload | close ``` ### Snapshot (Always use -i --json) ```bash agent-browser snapshot -i --json # Interactive elements, JSON output agent-browser snapshot -i -c -d 5 --json # + compact, depth limit agent-browser snapshot -s "#main" -i # Scope to selector ``` ### Interactions (Ref-based) ```bash agent-browser click @e2 agent-browser fill @e3 "text" agent-browser type @e3 "text" agent-browser hover @e4 agent-browser check @e5 | uncheck @e5 agent-browser select @e6 "value" agent-browser press "Enter" agent-browser scroll down 500 agent-browser drag @e7 @e8 ``` ### Get Information ```bash agent-browser get text @e1 --json agent-browser get html @e2 --json agent-browser get value @e3 --json agent-browser get attr @e4 "href" --json agent-browser get title --json agent-browser get url --json agent-browser get count ".item" --json ``` ### Check State ```bash agent-browser is visible @e2 --json agent-browser is enabled @e3 --json agent-browser is checked @e4 --json ``` ### Wait ```bash agent-browser wait @e2 # Wait for element agent-browser wait 1000 # Wait ms agent-browser wait --text "Welcome" # Wait for text agent-browser wait --url "**/dashboard" # Wait for URL agent-browser wait --load networkidle # Wait for network agent-browser wait --fn "window.ready === true" ``` ### Sessions (Isolated Browsers) ```bash agent-browser --session admin open site.com agent-browser --session user open site.com agent-browser session list # Or via env: AGENT_BROWSER_SESSION=admin agent-browser ... ``` ### State Persistence ```bash agent-browser state save auth.json # Save cookies/storage agent-browser state load auth.json # Load (skip login) ``` ### Screenshots & PDFs ```bash agent-browser screenshot page.png agent-browser screenshot --full page.png agent-browser pdf page.pdf ``` ### Network Control ```bash agent-browser network route "**/ads/*" --abort # Block agent-browser network route "**/api/*" --body '{"x":1}' # Mock agent-browser network requests --filter api # View ``` ### Cookies & Storage ```bash agent-browser cookies # Get all agent-browser cookies set name value agent-browser storage local key # Get localStorage agent-browser storage local set key val ``` ### Tabs & Frames ```bash agent-browser tab new https://example.com agent-browser tab 2 # Switch to tab agent-browser frame @e5 # Switch to iframe agent-browser frame main # Back to main ``` ## Snapshot Output Format ```json { "success": true, "data": { "snapshot": "...", "refs": { "e1": {"role": "heading", "name": "Example Domain"}, "e2": {"role": "button", "name": "Submit"}, "e3": {"role": "textbox", "name": "Email"} } } } ``` ## Best Practices 1. **Always use `-i` flag** - Focus on interactive elements 2. **Always use `--json`** - Easier to parse 3. **Wait for stability** - `agent-browser wait --load networkidle` 4. **Save auth state** - Skip login flows with `state save/load` 5. **Use sessions** - Isolate different browser contexts 6. **Use `--headed` for debugging** - See what's happening ## Example: Search and Extract ```bash agent-browser open https://www.google.com agent-browser snapshot -i --json # AI identifies search box @e1 agent-browser fill @e1 "AI agents" agent-browser press Enter agent-browser wait --load networkidle agent-browser snapshot -i --json # AI identifies result refs agent-browser get text @e3 --json agent-browser get attr @e4 "href" --json ``` ## Example: Multi-Session Testing ```bash # Admin session agent-browser --session admin open app.com agent-browser --session admin state load admin-auth.json agent-browser --session admin snapshot -i --json # User session (simultaneous) agent-browser --session user open app.com agent-browser --session user state load user-auth.json agent-browser --session user snapshot -i --json ``` ## Installation ```bash npm install -g agent-browser agent-browser install # Download Chromium agent-browser install --with-deps # Linux: + system deps ``` ## Credits Skill created by Yossi Elkrief ([@MaTriXy](https://github.com/MaTriXy)) agent-browser CLI by [Vercel Labs](https://github.com/vercel-labs/agent-browser)
