Claude Code Skill

For Claude Code, a skill provides richer context for browser automation:

mkdir -p ~/.claude/skills/browser-use
curl -o ~/.claude/skills/browser-use/SKILL.md \

How It Works

The CLI uses a session server architecture:

1. First command starts a background server (browser stays open)
2. Subsequent commands communicate via Unix socket
3. Browser persists across commands for fast interaction
4. Server auto-starts when needed, stops with browser-use server stop

This gives you ~50ms command latency instead of waiting for browser startup each time.
