Stand up the project's live app and hand it to the user to try a change firsthand, then act on their verdict once they reply. Use when the user asks to "preview the change", "let me try it", "spin up the app so I can test it", "set it up so I can poke at it", or before finalizing a UI/UX change that needs human eyes.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Preview Bring up the running app and let the user drive it themselves to judge the change, then act on their verdict. ## Step 1: Determine Scope Resolve what to preview using the first match: 1. **User-specified** — the user says what to look at. Use that. 2. **PR** — a PR URL or number is provided. Fetch its details and read the changed code. 3. **Conversation context** — prior conversation contains recent work. Extract what changed, where it lives, and the expected behavior. 4. **App-level discovery** — fresh context with no prior work. Examine entry points, routes, and the README to identify the app's core user-facing flows. If the resolved scope has no user-visible surface to try (a CLI-only change, a library with no entry point, backend work with no UI to look at), present this message: "Nothing to preview — <one-line reason>." Then use the TaskList tool and proceed to any remaining task. ## Step 2: Determine Launch Approach Check for a project-specific skill or MCP tool that launches the app, and use it if present. Otherwise use the fallback for the surface type: - **Web app** → start the dev server; the access point is the local URL and port …

How to install
mdr add tobihagemann/turbo/preview@sha256:4b01dffdef67bf69The line at the top of this page pins the label git:20261013.7173b0c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
