# Argo CD Application Inspection
Use the dev and prod server addresses from the project's `CLAUDE.md`.
Always ask which environment (dev or prod) before running commands if not specified.
**Tokens expire daily.** On any auth error, re-authenticate automatically without asking the user:
```bash
argocd login <dev-server> --sso
```
## Common Commands
```bash
# Check an app
argocd app get <app-name> --server <dev-server> --grpc-web
# Find apps with issues
argocd app list --server <dev-server> --grpc-web | grep -E "(Unknown|Progressing|Degraded|Missing|OutOfSync)"
# View deployment history
argocd app history <app-name> --server <dev-server> --grpc-web
# Check resource-level status
argocd app resources <app-name> --server <dev-server> --grpc-web
```
When reporting issues, include the UI link: `https://<dev-or-prod-server>/applications/<app-name>`
