# Send Agent Browser to your agent Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually. ## Fast path - Download the package from Yavira. - Extract it into a folder your agent can access. - Paste one of the prompts below and point your agent at the extracted folder. ## Suggested prompts ### New install ```text I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete. ``` ### Upgrade existing ```text I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "agent-browser-4", "name": "Agent Browser", "source": "tencent", "type": "skill", "category": "开发工具", "sourceUrl": "https://clawhub.ai/Justinpoulido/agent-browser-4", "canonicalUrl": "https://clawhub.ai/Justinpoulido/agent-browser-4", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/agent-browser-4", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=agent-browser-4", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md", "references/authentication.md", "references/commands.md", "references/profiling.md", "references/proxy-support.md", "references/session-management.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "agent-browser-4", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-04-29T10:17:53.298Z", "expiresAt": "2026-05-06T10:17:53.298Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=agent-browser-4", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=agent-browser-4", "contentDisposition": "attachment; filename=\"agent-browser-4-0.1.0.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "agent-browser-4" }, "scope": "item", "summary": "Item download looks usable.", "detail": "Yavira can redirect you to the upstream package for this item.", "primaryActionLabel": "Download for OpenClaw", "primaryActionHref": "/downloads/agent-browser-4" }, "validation": { "installChecklist": [ "Use the Yavira download entry.", "Review SKILL.md after the package is downloaded.", "Confirm the extracted package contains the expected setup assets." ], "postInstallChecks": [ "Confirm the extracted package includes the expected docs or setup files.", "Validate the skill or prompts are available in your target agent workspace.", "Capture any manual follow-up steps the agent could not complete." ] } }, "links": { "detailUrl": "https://openagent3.xyz/skills/agent-browser-4", "downloadUrl": "https://openagent3.xyz/downloads/agent-browser-4", "agentUrl": "https://openagent3.xyz/skills/agent-browser-4/agent", "manifestUrl": "https://openagent3.xyz/skills/agent-browser-4/agent.json", "briefUrl": "https://openagent3.xyz/skills/agent-browser-4/agent.md" } } ``` ## Documentation ### Core Workflow Every browser automation follows this pattern: Navigate: agent-browser open Snapshot: agent-browser snapshot -i (get element refs like @e1, @e2) Interact: Use refs to click, fill, select Re-snapshot: After navigation or DOM changes, get fresh refs agent-browser open https://example.com/form agent-browser snapshot -i # Output: @e1 [input type="email"], @e2 [input type="password"], @e3 [button] "Submit" agent-browser fill @e1 "user@example.com" agent-browser fill @e2 "password123" agent-browser click @e3 agent-browser wait --load networkidle agent-browser snapshot -i # Check result ### Command Chaining Commands can be chained with && in a single shell invocation. The browser persists between commands via a background daemon, so chaining is safe and more efficient than separate calls. # Chain open + wait + snapshot in one call agent-browser open https://example.com && agent-browser wait --load networkidle && agent-browser snapshot -i # Chain multiple interactions agent-browser fill @e1 "user@example.com" && agent-browser fill @e2 "password123" && agent-browser click @e3 # Navigate and capture agent-browser open https://example.com && agent-browser wait --load networkidle && agent-browser screenshot page.png When to chain: Use && when you don't need to read the output of an intermediate command before proceeding (e.g., open + wait + screenshot). Run commands separately when you need to parse the output first (e.g., snapshot to discover refs, then interact using those refs). ### Essential Commands # Navigation agent-browser open # Navigate (aliases: goto, navigate) agent-browser close # Close browser # Snapshot agent-browser snapshot -i # Interactive elements with refs (recommended) agent-browser snapshot -i -C # Include cursor-interactive elements (divs with onclick, cursor:pointer) agent-browser snapshot -s "#selector" # Scope to CSS selector # Interaction (use @refs from snapshot) agent-browser click @e1 # Click element agent-browser click @e1 --new-tab # Click and open in new tab agent-browser fill @e2 "text" # Clear and type text agent-browser type @e2 "text" # Type without clearing agent-browser select @e1 "option" # Select dropdown option agent-browser check @e1 # Check checkbox agent-browser press Enter # Press key agent-browser scroll down 500 # Scroll page # Get information agent-browser get text @e1 # Get element text agent-browser get url # Get current URL agent-browser get title # Get page title # Wait agent-browser wait @e1 # Wait for element agent-browser wait --load networkidle # Wait for network idle agent-browser wait --url "**/page" # Wait for URL pattern agent-browser wait 2000 # Wait milliseconds # Capture agent-browser screenshot # Screenshot to temp dir agent-browser screenshot --full # Full page screenshot agent-browser screenshot --annotate # Annotated screenshot with numbered element labels agent-browser pdf output.pdf # Save as PDF ### Form Submission agent-browser open https://example.com/signup agent-browser snapshot -i agent-browser fill @e1 "Jane Doe" agent-browser fill @e2 "jane@example.com" agent-browser select @e3 "California" agent-browser check @e4 agent-browser click @e5 agent-browser wait --load networkidle ### Authentication with State Persistence # Login once and save state agent-browser open https://app.example.com/login agent-browser snapshot -i agent-browser fill @e1 "$USERNAME" agent-browser fill @e2 "$PASSWORD" agent-browser click @e3 agent-browser wait --url "**/dashboard" agent-browser state save auth.json # Reuse in future sessions agent-browser state load auth.json agent-browser open https://app.example.com/dashboard ### Session Persistence # Auto-save/restore cookies and localStorage across browser restarts agent-browser --session-name myapp open https://app.example.com/login # ... login flow ... agent-browser close # State auto-saved to ~/.agent-browser/sessions/ # Next time, state is auto-loaded agent-browser --session-name myapp open https://app.example.com/dashboard # Encrypt state at rest export AGENT_BROWSER_ENCRYPTION_KEY=$(openssl rand -hex 32) agent-browser --session-name secure open https://app.example.com # Manage saved states agent-browser state list agent-browser state show myapp-default.json agent-browser state clear myapp agent-browser state clean --older-than 7 ### Data Extraction agent-browser open https://example.com/products agent-browser snapshot -i agent-browser get text @e5 # Get specific element text agent-browser get text body > page.txt # Get all page text # JSON output for parsing agent-browser snapshot -i --json agent-browser get text @e1 --json ### Parallel Sessions agent-browser --session site1 open https://site-a.com agent-browser --session site2 open https://site-b.com agent-browser --session site1 snapshot -i agent-browser --session site2 snapshot -i agent-browser session list ### Connect to Existing Chrome # Auto-discover running Chrome with remote debugging enabled agent-browser --auto-connect open https://example.com agent-browser --auto-connect snapshot # Or with explicit CDP port agent-browser --cdp 9222 snapshot ### Visual Browser (Debugging) agent-browser --headed open https://example.com agent-browser highlight @e1 # Highlight element agent-browser record start demo.webm # Record session agent-browser profiler start # Start Chrome DevTools profiling agent-browser profiler stop trace.json # Stop and save profile (path optional) ### Local Files (PDFs, HTML) # Open local files with file:// URLs agent-browser --allow-file-access open file:///path/to/document.pdf agent-browser --allow-file-access open file:///path/to/page.html agent-browser screenshot output.png ### iOS Simulator (Mobile Safari) # List available iOS simulators agent-browser device list # Launch Safari on a specific device agent-browser -p ios --device "iPhone 16 Pro" open https://example.com # Same workflow as desktop -

Use --device "" where UDID is from xcrun xctrace list devices. ### Timeouts and Slow Pages The default Playwright timeout is 60 seconds for local browsers. For slow websites or large pages, use explicit waits instead of relying on the default timeout: # Wait for network activity to settle (best for slow pages) agent-browser wait --load networkidle # Wait for a specific element to appear agent-browser wait "#content" agent-browser wait @e1 # Wait for a specific URL pattern (useful after redirects) agent-browser wait --url "**/dashboard" # Wait for a JavaScript condition agent-browser wait --fn "document.readyState === 'complete'" # Wait a fixed duration (milliseconds) as a last resort agent-browser wait 5000 When dealing with consistently slow websites, use wait --load networkidle after open to ensure the page is fully loaded before taking a snapshot. If a specific element is slow to render, wait for it directly with wait or wait @ref. ### Session Management and Cleanup When running multiple agents or automations concurrently, always use named sessions to avoid conflicts: # Each agent gets its own isolated session agent-browser --session agent1 open site-a.com agent-browser --session agent2 open site-b.com # Check active sessions agent-browser session list Always close your browser session when done to avoid leaked processes: agent-browser close # Close default session agent-browser --session agent1 close # Close specific session If a previous session was not closed properly, the daemon may still be running. Use agent-browser close to clean it up before starting new work. ### Ref Lifecycle (Important) Refs (@e1, @e2, etc.) are invalidated when the page changes. Always re-snapshot after: Clicking links or buttons that navigate Form submissions Dynamic content loading (dropdowns, modals) agent-browser click @e5 # Navigates to new page agent-browser snapshot -i # MUST re-snapshot agent-browser click @e1 # Use new refs ### Annotated Screenshots (Vision Mode) Use --annotate to take a screenshot with numbered labels overlaid on interactive elements. Each label [N] maps to ref @eN. This also caches refs, so you can interact with elements immediately without a separate snapshot. agent-browser screenshot --annotate # Output includes the image path and a legend: # [1] @e1 button "Submit" # [2] @e2 link "Home" # [3] @e3 textbox "Email" agent-browser click @e2 # Click using ref from annotated screenshot Use annotated screenshots when: The page has unlabeled icon buttons or visual-only elements You need to verify visual layout or styling Canvas or chart elements are present (invisible to text snapshots) You need spatial reasoning about element positions ### Semantic Locators (Alternative to Refs) When refs are unavailable or unreliable, use semantic locators: agent-browser find text "Sign In" click agent-browser find label "Email" fill "user@test.com" agent-browser find role button click --name "Submit" agent-browser find placeholder "Search" type "query" agent-browser find testid "submit-btn" click ### JavaScript Evaluation (eval) Use eval to run JavaScript in the browser context. Shell quoting can corrupt complex expressions -- use --stdin or -b to avoid issues. # Simple expressions work with regular quoting agent-browser eval 'document.title' agent-browser eval 'document.querySelectorAll("img").length' # Complex JS: use --stdin with heredoc (RECOMMENDED) agent-browser eval --stdin <<'EVALEOF' JSON.stringify( Array.from(document.querySelectorAll("img")) .filter(i => !i.alt) .map(i => ({ src: i.src.split("/").pop(), width: i.width })) ) EVALEOF # Alternative: base64 encoding (avoids all shell escaping issues) agent-browser eval -b "$(echo -n 'Array.from(document.querySelectorAll("a")).map(a => a.href)' | base64)" Why this matters: When the shell processes your command, inner double quotes, ! characters (history expansion), backticks, and $() can all corrupt the JavaScript before it reaches agent-browser. The --stdin and -b flags bypass shell interpretation entirely. Rules of thumb: Single-line, no nested quotes -> regular eval 'expression' with single quotes is fine Nested quotes, arrow functions, template literals, or multiline -> use eval --stdin <<'EVALEOF' Programmatic/generated scripts -> use eval -b with base64 ### Configuration File Create agent-browser.json in the project root for persistent settings: { "headed": true, "proxy": "http://localhost:8080", "profile": "./browser-data" } Priority (lowest to highest): ~/.agent-browser/config.json < ./agent-browser.json < env vars < CLI flags. Use --config or AGENT_BROWSER_CONFIG env var for a custom config file (exits with error if missing/invalid). All CLI options map to camelCase keys (e.g., --executable-path -> "executablePath"). Boolean flags accept true/false values (e.g., --headed false overrides config). Extensions from user and project configs are merged, not replaced. ### Deep-Dive Documentation ReferenceWhen to Usereferences/commands.mdFull command reference with all optionsreferences/snapshot-refs.mdRef lifecycle, invalidation rules, troubleshootingreferences/session-management.mdParallel sessions, state persistence, concurrent scrapingreferences/authentication.mdLogin flows, OAuth, 2FA handling, state reusereferences/video-recording.mdRecording workflows for debugging and documentationreferences/profiling.mdChrome DevTools profiling for performance analysisreferences/proxy-support.mdProxy configuration, geo-testing, rotating proxies ### Ready-to-Use Templates TemplateDescriptiontemplates/form-automation.shForm filling with validationtemplates/authenticated-session.shLogin once, reuse statetemplates/capture-workflow.shContent extraction with screenshots ./templates/form-automation.sh https://example.com/form ./templates/authenticated-session.sh https://app.example.com/login ./templates/capture-workflow.sh https://example.com ./output ## Trust - Source: tencent - Verification: Indexed source record - Publisher: Justinpoulido - Version: 0.1.0 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-04-29T10:17:53.298Z - Expires at: 2026-05-06T10:17:53.298Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/agent-browser-4) - [Send to Agent page](https://openagent3.xyz/skills/agent-browser-4/agent) - [JSON manifest](https://openagent3.xyz/skills/agent-browser-4/agent.json) - [Markdown brief](https://openagent3.xyz/skills/agent-browser-4/agent.md) - [Download page](https://openagent3.xyz/downloads/agent-browser-4)
