+# Prevu Preview Environments
+
+## Purpose
+
+This skill guides an agent through using Prevu as a preview environment layer
+for coding-agent work. Prevu gives agents a real VM-backed environment, SSH
+access, service inspection, logs, and public HTTPS preview URLs so humans can
+review running software before production.
+
+Use this skill when the task involves:
+
+- Creating or managing a Prevu environment.
+- Running work-in-progress code in a real staging VM.
+- Exposing a running app as a public HTTPS preview URL.
+- Sharing a preview link with a teammate, designer, PM, or mobile reviewer.
+- Debugging a Prevu environment with SSH, service status, ports, and logs.
+
+Do not present Prevu as a production deployment target unless the user
+explicitly asks about production. Treat it as a staging and review surface.
+
+## Preconditions
+
+- The Prevu CLI is installed or can be installed.
+- The user is signed in with `prevu auth login`, or an approved `PREVU_TOKEN` is
+  already available in automation.
+- The app can bind to a network-accessible host such as `0.0.0.0`.
+
+## Install and Authenticate
+
+```bash
+npm install -g @prevu/cli
+prevu auth status
+```
+
+If auth is missing:
+
+```bash
+prevu auth login
+```
+
+Do not create new access tokens or paste secrets into logs, public URLs, issue
+comments, or documentation without explicit approval.
+
+## Create or Select an Environment
+
+List existing environments first when the user may already have one:
+
+```bash
+prevu env list
+```
+
+Create a new environment with a short slug:
+
+```bash
+prevu env create my-app-preview
+```
+
+## Debug Through SSH
+
+SSH into the environment when setup or runtime inspection is needed:
+
+```bash
+prevu env ssh my-app-preview
+```
+
+Inside the VM, check the working directory, processes, listening ports, and local
+HTTP response before changing configuration:
+
+```bash
+pwd
+ls
+ps aux
+ss -ltnp
+curl -I http://127.0.0.1:3000
+```
+
+## Expose the App
+
+Expose the port the app actually listens on:
+
+```bash
+prevu env expose my-app-preview --port 3000
+```
+
+Return the generated HTTPS URL to the user and identify what is running:
+
+```text
+Preview URL: https://my-app-preview-3000.prevu.page
+Running: development server on port 3000
+Ready for: teammate review, mobile review, PM signoff
+```
+
+## Inspect Services and Logs
+
+Before restarting or rebuilding, inspect service state and logs:
+
+```bash
+prevu env services my-app-preview
+prevu env logs my-app-preview
+```
+
+Prefer a service-specific log command when the CLI provides one.
+
+## Common Fixes
+
+If the preview URL returns a blocked-host error, update the framework dev server
+configuration to allow the Prevu hostname. For Vite projects, this usually means
+setting `server.allowedHosts` in `vite.config.ts`.
+
+If the port is not reachable, confirm the app is listening on the expected port
+and is not bound only to an inaccessible interface.
+
+If a private repository cannot be cloned inside the VM, use an approved access
+path such as an existing local archive or authenticated GitHub CLI flow. Do not
+create new credentials without approval.
+
+## Verification
+
+- [ ] The environment exists and is reachable through the Prevu CLI.
+- [ ] The app process is running in the environment.
+- [ ] The intended port is listening.
+- [ ] The public HTTPS preview URL returns the expected app.
+- [ ] The user receives the exact preview URL and any known caveats.
+
+## Cleanup
+
+Ask before deleting environments unless the user already authorized cleanup:
+
+```bash
+prevu env delete my-app-preview
+```
