Browser Automation with agent-browser

Name: Agent Browser Backup
Author: lorexxar

Installation

npm recommended

npm install -g agent-browser
agent-browser install
agent-browser install --with-deps

From Source

git clone https://github.com/vercel-labs/agent-browser
cd agent-browser
pnpm install
pnpm build
agent-browser install

Quick start

agent-browser open \x3Curl>        # Navigate to page
agent-browser snapshot -i       # Get interactive elements with refs
agent-browser click @e1         # Click element by ref
agent-browser fill @e2 "text"   # Fill input by ref
agent-browser close             # Close browser

Core workflow

Navigate: agent-browser open \x3Curl>
Snapshot: agent-browser snapshot -i (returns elements with refs like @e1, @e2)
Interact using refs from the snapshot
Re-snapshot after navigation or significant DOM changes

Commands

Navigation

agent-browser open \x3Curl>      # Navigate to URL
agent-browser back            # Go back
agent-browser forward         # Go forward
agent-browser reload          # Reload page
agent-browser close           # Close browser

Snapshot (page analysis)

agent-browser snapshot            # Full accessibility tree
agent-browser snapshot -i         # Interactive elements only (recommended)
agent-browser snapshot -c         # Compact output
agent-browser snapshot -d 3       # Limit depth to 3
agent-browser snapshot -s "#main" # Scope to CSS selector

Interactions (use @refs from snapshot)

agent-browser click @e1           # Click
agent-browser dblclick @e1        # Double-click
agent-browser focus @e1           # Focus element
agent-browser fill @e2 "text"     # Clear and type
agent-browser type @e2 "text"     # Type without clearing
agent-browser press Enter         # Press key
agent-browser press Control+a     # Key combination
agent-browser keydown Shift       # Hold key down
agent-browser keyup Shift         # Release key
agent-browser hover @e1           # Hover
agent-browser check @e1           # Check checkbox
agent-browser uncheck @e1         # Uncheck checkbox
agent-browser select @e1 "value"  # Select dropdown
agent-browser scroll down 500     # Scroll page
agent-browser scrollintoview @e1  # Scroll element into view
agent-browser drag @e1 @e2        # Drag and drop
agent-browser upload @e1 file.pdf # Upload files

Get information

agent-browser get text @e1        # Get element text
agent-browser get html @e1        # Get innerHTML
agent-browser get value @e1       # Get input value
agent-browser get attr @e1 href   # Get attribute
agent-browser get title           # Get page title
agent-browser get url             # Get current URL
agent-browser get count ".item"   # Count matching elements
agent-browser get box @e1         # Get bounding box

Check state

agent-browser is visible @e1      # Check if visible
agent-browser is enabled @e1      # Check if enabled
agent-browser is checked @e1      # Check if checked

Screenshots & PDF

agent-browser screenshot          # Screenshot to stdout
agent-browser screenshot path.png # Save to file
agent-browser screenshot --full   # Full page
agent-browser pdf output.pdf      # Save as PDF

Video recording

agent-browser record start ./demo.webm    # Start recording (uses current URL + state)
agent-browser click @e1                   # Perform actions
agent-browser record stop                 # Stop and save video
agent-browser record restart ./take2.webm # Stop current + start new recording

Recording creates a fresh context but preserves cookies/storage from your session. If no URL is provided, it automatically returns to your current page. For smooth demos, explore first, then start recording.

Wait

agent-browser wait @e1                     # Wait for element
agent-browser wait 2000                    # Wait milliseconds
agent-browser wait --text "Success"        # Wait for text
agent-browser wait --url "/dashboard"    # Wait for URL pattern
agent-browser wait --load networkidle      # Wait for network idle
agent-browser wait --fn "window.ready"     # Wait for JS condition

Mouse control

agent-browser mouse move 100 200      # Move mouse
agent-browser mouse down left         # Press button
agent-browser mouse up left           # Release button
agent-browser mouse wheel 100         # Scroll wheel

Semantic locators (alternative to refs)

agent-browser find role button click --name "Submit"
agent-browser find text "Sign In" click
agent-browser find label "Email" fill "[email protected]"
agent-browser find first ".item" click
agent-browser find nth 2 "a" text

agent-browser snapshot -i
# Output shows: textbox "Email" [ref=e1], textbox "Password" [ref=e2], button "Submit" [ref=e3]

agent-browser fill @e1 "[email protected]"
agent-browser fill @e2 "password123"
agent-browser click @e3
agent-browser wait --load networkidle
agent-browser snapshot -i  # Check result

Example: Authentication with saved state

# Login once
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

# Later sessions: load saved state
agent-browser state load auth.json
agent-browser open https://app.example.com/dashboard

Sessions (parallel browsers)

agent-browser --session test1 open site-a.com
agent-browser --session test2 open site-b.com
agent-browser session list

JSON output (for parsing)

Add --json for machine-readable output:

agent-browser snapshot -i --json
agent-browser get text @e1 --json

Debugging

agent-browser open example.com --headed              # Show browser window
agent-browser console                                # View console messages
agent-browser console --clear                        # Clear console
agent-browser errors                                 # View page errors
agent-browser errors --clear                         # Clear errors
agent-browser highlight @e1                          # Highlight element
agent-browser trace start                            # Start recording trace
agent-browser trace stop trace.zip                   # Stop and save trace
agent-browser record start ./debug.webm              # Record from current page
agent-browser record stop                            # Save recording
agent-browser --cdp 9222 snapshot                    # Connect via CDP

Troubleshooting

If the command is not found on Linux ARM64, use the full path in the bin folder.
If an element is not found, use snapshot to find the correct ref.
If the page is not loaded, add a wait command after navigation.
Use --headed to see the browser window for debugging.

Options

--session \x3Cname> uses an isolated session.
--json provides JSON output.
--full takes a full page screenshot.
--headed shows the browser window.
--timeout sets the command timeout in milliseconds.
--cdp \x3Cport> connects via Chrome DevTools Protocol.

Notes

Refs are stable per page load but change on navigation.
Always snapshot after navigation to get new refs.
Use fill instead of type for input fields to ensure existing text is cleared.

Usage Guidance

This skill is a wrapper for an external CLI and is instruction-only, but there are a few red flags to check before installing or giving it broad access: 1) Verify the upstream package/repo: confirm the npm package owner and inspect the GitHub repository (npm view agent-browser, check repository code and releases). 2) Confirm required tooling: SKILL.md uses pnpm, git and implies Rust — ensure you have the right toolchain and understand what 'agent-browser install --with-deps' will fetch. 3) Run in a sandbox: because the CLI can read cookies, storage, take screenshots, and upload files, run it in an isolated container or throwaway environment until you trust it. 4) Limit agent privileges: avoid letting an autonomous agent use this skill on sensitive sites or local files, and avoid providing secrets/credentials unless absolutely necessary. 5) If you plan to build from source, inspect build scripts for network downloads or native binaries. Resolving the declared vs. documented tooling mismatch (pnpm/git/cargo vs. node/npm) would raise confidence; until then treat the package with caution.

Capability Analysis

Type: OpenClaw Skill Name: agent-browser-backup Version: 1.0.0 The skill bundle is a comprehensive wrapper for the 'agent-browser' CLI, a legitimate browser automation tool developed by Vercel Labs. It provides the AI agent with structured commands for web navigation, interaction, and state management, including high-risk but functional capabilities like cookie retrieval, local storage access, and JavaScript execution ('eval'). While these tools could be abused to exfiltrate session data, the SKILL.md and documentation contain no malicious instructions, prompt injections, or hidden payloads; they strictly describe the tool's intended use for automation and testing. The links provided point to legitimate repositories (github.com/vercel-labs/agent-browser), and the 'agent-browser-backup' slug appears to be a non-malicious naming variation.

Capability Assessment

⚠ Purpose & Capability

The SKILL.md describes a Rust-based CLI with a Node.js fallback but the skill metadata only declares node/npm as required binaries. The installation instructions reference pnpm and git (and a GitHub repo), and the description implies a Rust component (which would normally suggest a Rust toolchain/cargo). These build/runtime tooling mentions are not reflected in the declared required binaries/metadata and the source/homepage are unknown — this mismatch is unexplained and worth verifying.

ℹ Instruction Scope

The instructions are focused on browser automation and list many expected commands (navigate, snapshot, click, fill, screenshot, record, upload, set headers, set credentials, cookies/storage access). That scope is appropriate for a browser automation CLI, but several commands allow access to sensitive artifacts (cookies, localStorage, file uploads, headers, and HTTP basic auth). There are no instructions that directly command reading unrelated system files, but the agent running this CLI could be used to capture or transmit page content or local files — so usage should be restricted and monitored.

✓ Install Mechanism

This is an instruction-only skill (no install spec, no code files). That keeps the platform risk low. However, the SKILL.md suggests running network installs (npm install -g agent-browser, agent-browser install --with-deps) and building from source via git + pnpm; those client-side install steps will fetch remote code and dependencies, so users should verify the upstream package/repo before running them locally.

ℹ Credentials

The skill declares no required environment variables or credentials, which is proportionate for a CLI wrapper. However, the CLI supports setting HTTP headers, credentials, and uploading local files at runtime — these capabilities can be used to access or transmit secrets or local data even if no env vars are requested. The metadata also omits pnpm/git/cargo which are referenced by the docs; that omission should be clarified.

✓ Persistence & Privilege

The skill does not request always:true and is user-invocable. The default ability for the agent to invoke the skill autonomously is set to false in the flags? (platform default is allowed) — this is normal. There is no evidence the skill modifies other skills or system-wide configs.
