Automate web browser interactions using natural language via CLI commands. Use when the user asks to browse websites, navigate web pages, extract data from websites, take screenshots, fill forms, click buttons, or interact with web applications.

The description field of the SKILL.md. The agent reads only this at startup and decides from it when to load the full skill.

Install Browserbase Browser

The skills CLI copies the skill into the folder of each agent you pick (Claude Code, Codex, Cursor, Copilot, Gemini CLI, OpenCode, Windsurf...). Add -g for all projects. Needs Node.js 22.20+. docs

npx skills add browserbase/skills --skill browser

This repo is a plugin marketplace. Inside Claude Code, add it and install the plugin that holds the skill (browse, functions, browser-trace, safe-browser...), or copy only this skill into ~/.claude/skills. docs

/plugin marketplace add browserbase/skills
/plugin install <plugin>@browserbase

# or only this skill:
npx skills add browserbase/skills --skill browser -a claude-code

Download the skill folder, zip it, then Customize > Skills > + > Create skill > Upload a skill. Code execution must be on (Settings > Capabilities). docs

git clone --depth 1 https://github.com/browserbase/skills.git /tmp/browser-src

Codex reads skills from .agents/skills in the repo or ~/.agents/skills. Type $ in Codex to use one. docs

npx skills add browserbase/skills --skill browser -a codex

gh skill (GitHub CLI 2.90+, preview) installs it for Copilot in VS Code, the CLI and the cloud agent. Copilot also reads .github/skills and ~/.copilot/skills. docs

npx skills add browserbase/skills --skill browser -a opencode

Windsurf (now Devin Desktop) reads .devin/skills, .windsurf/skills and ~/.codeium/windsurf/skills. docs

Does Browserbase Browser work in Codex, Cursor and Copilot, or only Claude?+
