+# Secrets Management Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Remove secrets from the Helm chart and replace them with an idempotent kubectl bootstrap script at `scripts/create-secrets.sh`.
+
+**Architecture:** Delete the Helm-managed Secret template and strip secret values from values files so nothing sensitive ever lives in git. A standalone shell script pre-creates the Kubernetes Secret before ArgoCD first syncs; the existing `secretKeyRef` references in the deployments continue to work unchanged.
+
+**Tech Stack:** bash, kubectl, Helm 3
+
+---
+
+### Task 1: Delete the Helm Secret template
+
+**Files:**
+- Delete: `helm/shorefront/templates/secret.yaml`
+
+**Step 1: Delete the file**
+
+```bash
+rm helm/shorefront/templates/secret.yaml
+```
+
+**Step 2: Verify it's gone**
+
+```bash
+ls helm/shorefront/templates/
+```
+
+Expected: `secret.yaml` is not listed.
+
+**Step 3: Commit**
+
+```bash
+git add helm/shorefront/templates/secret.yaml
+git commit -m "feat: remove Helm-managed Secret template"
+```
+
+---
+
+### Task 2: Remove secrets block from values files
+
+**Files:**
+- Modify: `helm/shorefront/values.yaml` (lines 37-39)
+- Modify: `helm/shorefront/values-prod.yaml`
+
+**Step 1: Edit `values.yaml` — remove the `secrets:` block**
+
+Remove these lines from the bottom of `helm/shorefront/values.yaml`:
+
+```yaml
+secrets:
+  postgresPassword: changeme-in-prod
+  jwtSecretKey: changeme-in-prod
+```
+
+The file should end after the `ingress:` block:
+
+```yaml
+ingress:
+  host: shorefront.example.com
+  ingressClassName: traefik
+```
+
+**Step 2: Edit `values-prod.yaml` — replace comment with usage instructions**
+
+Replace the entire content of `helm/shorefront/values-prod.yaml` with:
+
+```yaml
+ingress:
+  host: shorefront.yourdomain.com
+
+# Secrets are NOT managed by Helm. Run scripts/create-secrets.sh before
+# the first helm install/ArgoCD sync:
+#
+#   export POSTGRES_PASSWORD=<real-password>
+#   export JWT_SECRET_KEY=<real-jwt-secret>
+#   bash scripts/create-secrets.sh
+```
+
+**Step 3: Verify helm template renders without errors**
+
+```bash
+helm template shorefront helm/shorefront/
+```
+
+Expected: renders all templates cleanly; no `shorefront-secret` Secret resource in output; no template errors.
+
+**Step 4: Commit**
+
+```bash
+git add helm/shorefront/values.yaml helm/shorefront/values-prod.yaml
+git commit -m "feat: remove secrets block from Helm values"
+```
+
+---
+
+### Task 3: Create the bootstrap script
+
+**Files:**
+- Create: `scripts/create-secrets.sh`
+
+**Step 1: Create `scripts/` directory and write the script**
+
+Create `scripts/create-secrets.sh` with this exact content:
+
+```bash
+#!/usr/bin/env bash
+set -euo pipefail
+
+NAMESPACE="shorefront"
+
+# --- Validate required env vars ---
+: "${POSTGRES_PASSWORD:?POSTGRES_PASSWORD is required}"
+: "${JWT_SECRET_KEY:?JWT_SECRET_KEY is required}"
+
+echo "Creating namespace '${NAMESPACE}' if it does not exist..."
+kubectl create namespace "${NAMESPACE}" --dry-run=client -o yaml | kubectl apply -f -
+
+echo "Creating/updating secret 'shorefront-secret' in namespace '${NAMESPACE}'..."
+kubectl create secret generic shorefront-secret \
+  --namespace "${NAMESPACE}" \
+  --from-literal=POSTGRES_PASSWORD="${POSTGRES_PASSWORD}" \
+  --from-literal=JWT_SECRET_KEY="${JWT_SECRET_KEY}" \
+  --dry-run=client -o yaml | kubectl apply -f -
+
+echo "Done. Secret 'shorefront-secret' is ready in namespace '${NAMESPACE}'."
+```
+
+**Step 2: Make it executable**
+
+```bash
+chmod +x scripts/create-secrets.sh
+```
+
+**Step 3: Verify the script is valid bash and has correct shebang**
+
+```bash
+bash -n scripts/create-secrets.sh && echo "syntax OK"
+```
+
+Expected output: `syntax OK`
+
+**Step 4: Dry-run the script without a cluster to confirm env var validation**
+
+```bash
+bash scripts/create-secrets.sh 2>&1 || true
+```
+
+Expected output:
+```
+scripts/create-secrets.sh: line N: POSTGRES_PASSWORD: POSTGRES_PASSWORD is required
+```
+
+(exits non-zero because the env vars are unset — this confirms the guard works)
+
+**Step 5: Commit**
+
+```bash
+git add scripts/create-secrets.sh
+git commit -m "feat: add scripts/create-secrets.sh for bootstrapping k8s secrets"
+```
