Getting Started

Steel Skills help coding agents use Steel cloud browsers correctly. Install the skill that matches what you want the agent to do: operate a browser now, write Steel code, diagnose a failed session, improve reliability, or turn a repeated browser task into a reusable workflow.

Most users should start with steel-browser and steel-developer. Add the debugging and reliability skills when you are running repeated workflows or investigating failed sessions.

Quick install

Use npx skills when you want a direct install command that works across supported coding agents.

npx skills add steel-dev/skills --list
npx skills add steel-dev/skills --skill steel-browser
npx skills add steel-dev/skills --skill steel-developer

Or use the Steel CLI helper:

steel skills install steel-browser
steel skills install steel-developer
steel skills doctor

Claude Code plugin marketplace

Use the plugin marketplace if you are working inside Claude Code and prefer Claude's plugin manager. Run these slash commands inside Claude Code.

Add the Steel Skills marketplace once, then install individual skills from it:

/plugin marketplace add steel-dev/skills
/plugin install steel-browser@steel-skills

Install another skill by replacing steel-browser with any catalog skill:

/plugin install steel-developer@steel-skills
/plugin install steel-session-debugging@steel-skills
/plugin install steel-reliability@steel-skills
/plugin install steel-skill-creator@steel-skills

The marketplace name is steel-skills.

Agent targets

Pass the target agent when you know where the skill should be installed:

npx skills add steel-dev/skills --skill steel-browser -a claude-code -g
npx skills add steel-dev/skills --skill steel-browser -a cursor -g
npx skills add steel-dev/skills --skill steel-browser -a codex -g
npx skills add steel-dev/skills --skill steel-browser -a opencode -g

Supported agent targets are Claude Code, Cursor, Codex, OpenCode, and Pi.

Which skill should I use?

• Use steel-browser for live web work the agent should perform now.
• Use steel-developer for code, scripts, docs, examples, SDKs, and app integrations.
• Use steel-session-debugging when a session failed and you need evidence-backed diagnosis.
• Use steel-reliability for bot detection, CAPTCHA, proxy, identity, login reliability, pacing, and retries.
• Use steel-skill-creator to turn recurring browser tasks into reusable workflows.
