**Technical Details:**
- Detects web environments via `CLAUDE_CODE_REMOTE=true`
- Starts local proxy wrapper on `127.0.0.1:18080` for authentication
- Adds `Proxy-Authorization` headers for HTTPS tunnel establishment
- Starts local proxy wrapper on a dynamically allocated port for authentication
- Handles both CONNECT tunnels (HTTPS) and plain HTTP requests
- Adds `Proxy-Authorization` headers automatically
- Respects `NO_PROXY`, `HTTP_PROXY`, and `HTTPS_PROXY` environment variables
- Uses Chrome by default for better stealth (falls back to Chromium)

See [SKILL.md](skills/playwright-skill/SKILL.md) for full auto-configuration documentation.

When running in **Claude Code for Web** environments, the skill automatically:

✅ **Detects the environment** - Uses official `CLAUDE_CODE_REMOTE` environment variable to detect web sessions
✅ **Starts proxy wrapper** - Automatically launches authentication wrapper on `127.0.0.1:18080`
✅ **Starts proxy wrapper** - Automatically launches authentication wrapper on a dynamic local port
✅ **Configures browser** - Prefers Chrome over Chromium for better stealth, sets up proxy, headless mode, and certificate handling
✅ **Enables external sites** - Full internet access through authenticated proxy
✅ **Enables external sites** - Full internet access through authenticated proxy (respects `NO_PROXY`)

**No configuration needed** - just use the skill normally:

The skill transparently handles:
- JWT proxy authentication (adds `Proxy-Authorization` headers)
- Both CONNECT tunnels (HTTPS) and plain HTTP requests through the proxy
- `NO_PROXY` / `HTTP_PROXY` / `HTTPS_PROXY` environment variables
- Headless mode (automatically enabled in web environments)
- Certificate validation (bypassed for proxy connections)
- HTTPS tunnel establishment (via local wrapper)
- Dynamic port allocation (no hardcoded ports)
- Chrome preference (uses Chrome if available, falls back to Chromium for better bot detection avoidance)
