+# Self-healing reminder workflow (OpenClaw/Eios style)
+
+## Goal
+Automatically remind maintainers when deployment-critical configuration or code artifacts are missing.
+
+## 1) Detect
+- On every deploy, open `/health-config` and validate required env keys.
+- On CI, run `pnpm --filter @workspace/sandbox-ai run build` and fail on errors.
+
+## 2) Classify
+- **Config missing** (e.g. `VITE_CLERK_PUBLISHABLE_KEY` when `VITE_AUTH_MODE=clerk`).
+- **Artifact missing** (route/page/module referenced but not found).
+- **Type/build breakage** (TypeScript/build errors).
+
+## 3) Notify owner
+- Config missing -> notify DevOps/release owner.
+- Artifact missing -> notify feature owner/repo maintainer.
+- Build/type breakage -> notify author of latest PR and reviewer.
+
+## 4) Auto-remediation checklist
+- If auth env missing in non-production: set `VITE_AUTH_MODE=public` as temporary fallback.
+- If auth env missing in production: block release and require secret injection.
+- If artifact missing: create placeholder file + TODO with owner and deadline.
+
+## 5) Prevent regressions
+- Add a PR checklist item: “Did you verify `/health-config` and auth mode behavior?”
+- Keep a short runbook for required variables per environment.
