 ## Deployment Workflow (MANDATORY for any apply/deploy)
 
-Whenever you run `terragrunt apply` or `kubectl set image`, you MUST follow this workflow:
-
-### Step 1: PRE-DEPLOY — Snapshot current state
-
-Before applying, capture the current pod state in the target namespace(s):
-
+### Step 1: PRE-DEPLOY -- Snapshot current pod state
 ```bash
 kubectl --kubeconfig /Users/viktorbarzin/code/config get pods -n <namespace> -o wide
 ```
 
-Identify which namespace(s) the stack affects from the Terraform resources.
-
-### Step 2: APPLY — Run the deployment
-
-Run terragrunt apply via the `scripts/tg` wrapper or directly:
-
+### Step 2: APPLY
 ```bash
 cd /Users/viktorbarzin/code/infra/stacks/<stack> && bash /Users/viktorbarzin/code/infra/scripts/tg apply --non-interactive
 ```
 
-### Step 3: SPAWN POD MONITOR — Immediately after apply
+### Step 3: SPAWN POD MONITOR -- Immediately after apply
+Spawn a background haiku subagent (`pod-monitor-<namespace>`) that checks pod status every 15s for 3 minutes. It reports:
+- `[SUCCESS]` when all pods Running with all containers Ready
+- `[FAILURE]` with logs/events for CrashLoopBackOff, OOMKilled, ImagePullBackOff, stuck Pending, probe failures
+- `[TIMEOUT]` after 3 minutes with current state
 
-Immediately after the apply completes, spawn a background subagent to monitor pod health in each affected namespace. Use the Agent tool with these parameters:
+Monitor is **read-only** -- never runs mutating kubectl commands.
 
-- **Name**: `pod-monitor-<namespace>`
-- **Model**: haiku
-- **Run in background**: true (do NOT block on this)
+### Step 4: REACT
+- **SUCCESS**: Report healthy deployment
+- **FAILURE**: Get full logs, events, resource usage; diagnose and report with remediation
+- **TIMEOUT**: Check state, report pending items, suggest next steps
 
-Use this prompt for the monitor subagent:
+## General Workflow (non-deploy)
 
-```
-Monitor pods in namespace "<NAMESPACE>" after a deployment change.
-Use kubectl --kubeconfig /Users/viktorbarzin/code/config for all commands.
-
-Run a monitoring loop — check pod status every 15 seconds for up to 3 minutes:
-
-1. Run: kubectl --kubeconfig /Users/viktorbarzin/code/config get pods -n <NAMESPACE> -o wide
-2. Parse pod status. Detect and report IMMEDIATELY if any pod shows:
-   - CrashLoopBackOff → include last 20 log lines: kubectl logs <pod> -n <NAMESPACE> --tail=20
-   - OOMKilled → include container name and memory limits from describe
-   - ImagePullBackOff → include the image name from describe
-   - Pending for more than 60 seconds → include events from describe
-   - Readiness probe failures → include events from describe
-3. If ALL pods in the namespace are Running and all containers are Ready (READY column shows all containers ready, e.g. 1/1, 2/2), report SUCCESS.
-4. If 3 minutes pass without all pods healthy, report TIMEOUT with current state.
-
-Output format (use exactly one of these):
-  [SUCCESS] All pods healthy in <NAMESPACE>: <pod names and status summary>
-  [FAILURE] <pod>: <reason> — Details: <relevant logs/events>
-  [TIMEOUT] Pods not ready after 3m in <NAMESPACE>: <pod names and status summary>
-
-IMPORTANT: You are READ-ONLY. Never run kubectl apply, edit, patch, delete, or any mutating command.
-```
-
-### Step 4: REACT — Act on monitor results
-
-- **On [SUCCESS]**: Report to user that deployment is healthy. Done.
-- **On [FAILURE]**: Investigate immediately:
-  - Get full logs: `kubectl logs <pod> -n <ns> --tail=50`
-  - Get events: `kubectl describe pod <pod> -n <ns>`
-  - Get resource usage: `kubectl top pod -n <ns>`
-  - Diagnose the root cause and report to user with remediation options
-- **On [TIMEOUT]**: Check current state, report what's still pending, suggest next steps
-
-## General Workflow (non-deploy tasks)
-
-1. Before reporting issues, read `.claude/reference/known-issues.md` and suppress any matches
-2. Run `bash /Users/viktorbarzin/code/infra/.claude/scripts/deploy-status.sh` to check deployment health
-3. Investigate specific issues:
-   - **Stalled rollouts**: Check Progressing condition, pod readiness, events
-   - **Image pull errors**: Registry connectivity, pull-through cache (10.0.20.10), tag existence
-   - **Woodpecker CI**: Build status via `kubectl exec` into woodpecker-server pod
-   - **Post-deploy health**: Verify via Uptime Kuma (use `uptime-kuma` skill) and service endpoints
-   - **DIUN**: Check for available image updates, report digest
-4. Report findings with clear remediation steps
+1. Read `.claude/reference/known-issues.md`, suppress matches
+2. Run `deploy-status.sh` for deployment health
+3. Investigate: stalled rollouts, image pull errors, Woodpecker CI status, post-deploy health, DIUN image updates
 
 ## Safe Operations
 
 - `terragrunt plan/apply` via `scripts/tg` wrapper
-- `kubectl set image` (for emergency image pins)
-- `kubectl rollout restart` (when Terraform image is :latest)
+- `kubectl set image` (emergency image pins)
+- `kubectl rollout restart` (when image is :latest)
 
 ## NEVER Do
 
 - Never `kubectl apply/edit/patch` raw manifests
-- Never delete PVCs or PVs
-- Never push to git without user approval
-- Never restart NFS on TrueNAS
-- Never rollback deployments without user approval
-
-## Reference
-
-- Use `uptime-kuma` skill for Uptime Kuma integration
-- Read `.claude/reference/service-catalog.md` for service inventory
+- Never delete PVCs/PVs, never push without user approval
+- Never restart NFS on TrueNAS, never rollback without approval
