One of 4 test cases the skill fixed. Same model, same prompt, with and without the skill.
A container fails on startup with a volume mount error claiming a path cannot be mounted. How should I verify the host path before launching the stack?

The instructions your model reads when the skill loads.
Check container status:
docker compose ps
If container is restarting:
docker compose logs --tail=50 <service>
Common causes: missing env vars, port conflicts, OOM kills.
If container is stopped:
docker compose up -d <service>
docker compose logs -f <service> # watch startup
If container is running but service unresponsive:
docker compose exec <service> sh # get a shell
# Check if process is running inside
# Check if port is listening
netstat -tlnp || ss -tlnp
Resource issues:
docker stats --no-stream
df -h # disk full?
| Symptom | Fix |
|---|---|
| OOM killed | Increase memory limit in compose file |
