Browserbase Skills

Browserbase Skills is a collection of skill plugins designed specifically for Claude Code, enabling users to control browsers directly via natural language. The project includes 10 core skills: browser (CLI-driven browser automation with remote Browserbase sessions featuring anti-bot stealth, auto CAPTCHA solving, residential proxies), browserbase-cli (Browserbase platform API operations), functions (serverless browser automation cloud deployment), site-debugger (diagnose automation failures and generate site playbooks), browser-trace (full CDP trace and DOM dump capture), bb-usage (terminal usage stats and cost forecasting), cookie-sync (sync local Chrome cookies to Browserbase persistent contexts), fetch (static page retrieval without browser sessions), search (structured web search results), and ui-test (AI-driven adversarial UI testing).

Dual-Mode Operation#

Supports both isolated local Chrome environments and remote Browserbase cloud sessions. Remote mode provides anti-bot stealth, automatic CAPTCHA solving, residential proxies covering 201 countries, and session persistence. The cookie-sync skill enables syncing local Chrome cookies to Browserbase persistent contexts for passwordless access to authenticated sites.

Use Cases#

• Web data extraction from sites with anti-scraping protections (leveraging cloud stealth and proxies)
• AI-driven adversarial UI automation testing and bug discovery
• Cross-site end-to-end workflow automation (e.g., auto-login and business operations)
• Browser automation script failure diagnosis and CDP-level trace debugging
• Serverless deployment of local browser automation scripts to Browserbase cloud

Architecture#

Each skill is defined in a skills/<name>/SKILL.md file using structured metadata (name, description, compatibility, bins, allowed-tools: [Bash], etc.). Execution chain: Claude Code parses natural language → matches Skill → triggers Bash tool → executes underlying CLI (browse or bb) → CLI communicates with the browser via CDP protocol. Primarily JavaScript/TypeScript, compiled with tsc, auto-built on postinstall.

Installation#

# Via Claude Code marketplace
/plugin marketplace add browserbase/skills
/plugin install browse@browserbase

# Generic install
npx skills add browserbase/skills

# Browser CLI dependency
which browse || npm install -g @browserbasehq/browse-cli

Remote mode requires the BROWSERBASE_API_KEY environment variable.

Key CLI Commands#

• Environment: browse env local / browse env remote
• Navigation: browse open <url>, browse reload, browse back, browse forward
• State: browse snapshot (accessibility tree), browse screenshot, browse get title
• Interaction: browse click @0-5, browse type, browse fill, browse select, browse press, browse drag, browse scroll
• Session: browse stop, browse status, browse pages, browse tab_switch

Unconfirmed Details#

• SKILL.md states MIT license, but no LICENSE file found in repository root
• Current version is 0.0.1, still in early stages
• The exact npm package name and install source for bb CLI is not specified in README
• Detailed command docs for fetch, search, ui-test skills are incomplete, possibly still in development
• Relationship with Anthropic Claude Code (official partner vs. third-party) remains unconfirmed
