Browserbase Skills

A set of skills for enabling Claude Code to work with Browserbase through browser automation and the official bb CLI.

Skills

This plugin includes the following skills (see skills/ for details):

Skill Description
browser Automate web browser interactions via CLI commands — supports remote Browserbase sessions with anti-bot stealth, CAPTCHA solving, and residential proxies
browserbase-cli Use the official bb CLI for Browserbase Functions and platform API workflows including sessions, projects, contexts, extensions, fetch, and dashboard
functions Deploy serverless browser automation to Browserbase cloud using the bb CLI
site-debugger Diagnose and fix failing browser automations — analyzes bot detection, selectors, timing, auth, and captchas, then generates a tested site playbook
bb-usage Show Browserbase usage stats, session analytics, and cost forecasts in a terminal dashboard
cookie-sync Sync cookies from local Chrome to a Browserbase persistent context so the browse CLI can access authenticated sites
fetch Fetch HTML or JSON from static pages without a browser session — inspect status codes, headers, follow redirects
search Search the web and return structured results (titles, URLs, metadata) without a browser session
ui-test AI-powered adversarial UI testing — analyzes git diffs to test changes, or explores the full app to find bugs

Installation

To install the skill to popular coding agents:

$ npx skills add browserbase/skills

Claude Code

On Claude Code, to add the marketplace, simply run:

/plugin marketplace add browserbase/skills

Then install the plugin:

/plugin install browse@browserbase

If you prefer the manual interface:

  1. On Claude Code, type /plugin
  2. Select option 3. Add marketplace
  3. Enter the marketplace source: browserbase/skills
  4. Press enter to select the browse plugin
  5. Hit enter again to Install now
  6. Restart Claude Code for changes to take effect

Usage

Once installed, you can ask Claude to browse or use the Browserbase CLI:

  • "Go to Hacker News, get the top post comments, and summarize them "
  • "QA test http://localhost:3000 and fix any bugs you encounter"
  • "Order me a pizza, you're already signed in on Doordash"
  • "Use bb to list my Browserbase projects and show the output as JSON"
  • "Initialize a new Browserbase Function with bb functions init and explain the next commands"

Claude will handle the rest.

For local and localhost work, browse env local now starts a clean isolated browser by default. Use browse env local --auto-connect when the agent should reuse your existing local Chrome session, cookies, or login state.

Troubleshooting

Chrome not found

Install Chrome for your platform:

Profile refresh
