browser-use
Automates browser interactions for web testing, form filling, screenshots, and data extraction
This is a thin wrapper skill for the legitimate browser-use CLI tool with comprehensive documentation declaring all capabilities including profile access, cookie management, Python execution, and tunnel creation.
Skill Namebrowser-use
Duration35.3s
Enginepi
✓
Safe to install
Approve for use with standard sandboxing. The skill is a documentation wrapper around browser-use CLI; verify browser-use package integrity separately. Profile access capability means authenticated sessions may be accessible - restrict profile options in untrusted environments.

Chrome Profile Access with Existing Authenticated Sessions
The skill can use --profile to access real Chrome profiles including Default profile, which contains existing logins, cookies, and potentially saved passwords. This grants access to authenticated sessions on any site.
browser-use --profile "Default" open https://github.com  # Already logged in
→ In untrusted environments, restrict profile access. Consider disallowing --profile flag for sensitive workflows.

Medium
Arbitrary Python Code Execution
The 'browser-use python' command allows execution of arbitrary Python code with persistent browser access. This is equivalent to shell access in terms of system control.
browser-use python "code"  # Execute Python (variables persist across calls)
→ Treat this capability as equivalent to shell:WRITE. Apply same restrictions as Bash access.

Low
Cloudflare Tunnel Creation
The 'browser-use tunnel' command can expose local ports to the internet via Cloudflare tunnels, creating potential attack vectors.
browser-use tunnel 3000  # → https://abc.trycloudflare.com
→ Monitor tunnel creation in production environments. Consider disallowing tunnel commands.

Info
External Cloudflare Tunnel URL
Skill uses trycloudflare.com for tunneling, an external URL. This is standard for legitimate tunnel services but worth noting.
https://abc.trycloudflare.com
→ No action needed - this is a legitimate tunneling service.
