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:

```
CONDUCTOR_PORT
```
env var →
```
(port - 55000) / 10 + 1
```
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

Quick Reference

Task	Command
Start full stack	`dev docker up -d`
Stop services	`dev docker down`
View all logs	`dev docker logs`
View service logs	`dev docker logs {service}`
Follow logs	`dev docker logs -f`
Check status	`dev docker ps`
Restart service	`dev docker restart {service}`
Shell access	`dev docker shell {service}`
Fresh start	`dev docker cleanup -f && dev docker up -d`
With monitoring	`dev docker up --monitoring -d`
Force rebuild	`dev docker up -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
minio	9000/9001	S3-compatible storage
prometheus	9090	Metrics (optional)
grafana	3001	Dashboards (optional)

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
