Local Environment Skill

This skill enables Claude to help manage the Polar local development environment using Docker. Use this when the user needs to start, stop, debug, or understand the local development stack.

Instance Auto-Detection

The dev docker command automatically detects the correct instance number. No manual -i flag is needed in most cases.

Detection priority:

1. CONDUCTOR_PORT env var → (port - 55000) / 10 + 1
2. Workspace path hash → stable instance derived from the repo root path

You can override with -i N if needed, but auto-detection handles Conductor workspaces automatically.

When to Use

• User asks to start/stop the local environment
• User needs to view logs or debug issues
• User wants to run multiple isolated instances
• User needs to understand the service architecture
• User encounters container or service errors
