+description: Deploy this repository's current worktree as a live development environment. Use when asked to deploy, start, redeploy, or publish the dev environment for this project.

+
+# Deploy Dev
+
+From the repository root, run:
+
+```bash
+./dev/start.sh
+```
+
+The script derives the instance and hostname from the worktree directory, applies the Kubernetes resources in `vibes`, and waits for rollout. Treat its final URL as the deployment URL.
+
+Verify that URL returns HTTP 200 with `curl --fail --max-time 15 <url>`, then report the URL. Do not inspect the codebase for another deployment method unless the script fails.
