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.
Conductor Integration
CRITICAL: When running in Conductor, always check CONDUCTOR_PORT first to determine the instance number:
bash
echo $CONDUCTOR_PORT
- If
CONDUCTOR_PORTis not set → Not running in Conductor, use instance 0 - If
CONDUCTOR_PORTis set → Calculate instance:INSTANCE=$((CONDUCTOR_PORT - 55090))
| CONDUCTOR_PORT | Instance |
|---|---|
| 55090 | 0 |
| 55091 | 1 |
| 55092 | 2 |
| 55093 | 3 |
Always use -i $INSTANCE flag with all docker-dev commands when running in Conductor.
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
Quick Reference
| Task | Command |
|---|---|
| Start full stack | ./dev/docker-dev -i $INSTANCE -d |
| Stop services | ./dev/docker-dev -i $INSTANCE down |
| View all logs | ./dev/docker-dev -i $INSTANCE logs |
| View service logs | ./dev/docker-dev -i $INSTANCE logs {service} |
| Follow logs | ./dev/docker-dev -i $INSTANCE logs -f |
| Check status | ./dev/docker-dev -i $INSTANCE ps |
| Restart service | ./dev/docker-dev -i $INSTANCE restart {service} |
| Shell access | ./dev/docker-dev -i $INSTANCE shell {service} |
| Fresh start | ./dev/docker-dev -i $INSTANCE cleanup && ./dev/docker-dev -i $INSTANCE -d |
| With monitoring | ./dev/docker-dev -i $INSTANCE --monitoring -d |
| Force rebuild | ./dev/docker-dev -i $INSTANCE -b -d |
Services
| Service | Default Port | Description |
|---|---|---|
| api | 8000 | FastAPI backend |
| worker | - | Background job processor |
| web | 3000 | Next.js frontend |
| db | 5432 | PostgreSQL database |
| redis | 6379 | Redis cache |

Instance Port Mapping
Port = Base Port + (Instance × 100)
| Instance | API | Web | DB | Redis | MinIO |
|---|---|---|---|---|---|
| 0 | 8000 | 3000 | 5432 | 6379 | 9000 |
| 1 | 8100 | 3100 | 5532 | 6479 | 9100 |
| 2 | 8200 | 3200 | 5632 | 6579 | 9200 |
