Adds "Agent Workflow Defaults" and "Commit & Push + ArgoCD CLI Checks" to AGENTS.md (via CLAUDE.md).\nStandardizes post-app-addition flow: commit/push, argocd login/sync/wait, and basic diagnostics.\n\nCommitted via Codex CLI.

 ## ArgoCD Migration Guidelines
 
+### Agent Workflow Defaults
+When migrating or adding an ArgoCD Application, always:
+- Create/update the Application manifest and any `helm-values/` files.
+- Git add, commit, and push the changes to the tracked branch.
+- Use the ArgoCD CLI to sync the app and wait for healthy status.

 ### Critical Configuration Preservation Rules

+### Commit & Push + ArgoCD CLI Checks
+After adding a new ArgoCD Application and values files:
+
+1. Commit and push the changes:
+   ```bash
+   git add applications/<app>.yaml helm-values/<app>_values.*
+   git commit -m "feat(argocd): add <app> application"
+   git push  # or: git push gitea master
+   ```
+
+2. ArgoCD CLI login (if not already authenticated):
+   ```bash
+   # Example options; adjust for your environment
+   # Get admin password if needed
+   kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath='{.data.password}' | base64 -d; echo
+
+   # Login (use your server/credentials)
+   argocd login argocd-server.argocd.svc.cluster.local --username admin --password <password> --insecure
+   ```
+
+3. Sync and wait for health:
+   ```bash
+   argocd app sync <app>
+   argocd app wait <app> --sync --health --timeout 300
+   argocd app get <app>
+   argocd app list | grep <app>
+   ```
+
+4. If sync fails, inspect details and events:
+   ```bash
+   argocd app history <app> --refresh
+   argocd app get <app> --refresh
+   kubectl -n default describe deploy/<app> || true
+   kubectl -n default get events --sort-by=.lastTimestamp | tail -n 50
