Use when the user wants to preview generated screens in a browser without starting Metro / a simulator — for example after /create-mobile-app finishes or after /edit-app regenerates a screen.
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
> **Plugin check**: Run `node "${PLUGIN_ROOT}/scripts/check-version.js"` - if it outputs a message, show it to the user before proceeding.
**Shared instructions: [shared-instructions.md](../../shared/shared-instructions.md)** — read first.
# Preview Screens
Generates a self-contained HTML file that renders every screen in the app as a phone-frame mockup (375 × 812) with tab navigation and a dark/light toggle. The agent reads TSX files, understands the Tamagui component tree, and produces equivalent HTML/CSS — no programmatic TSX parsing.
## When to use
- After generating screens, to see a quick visual preview without running Metro/Expo
- To share a screenshot-ready mockup with stakeholders
- To verify layout before deploying
## When NOT to use
- To run the actual app → use `npm run dev`
- To modify screens → use `/edit-app`; `screen-builder` is an internal agent invoked by orchestrator skills
## Workflow
1. Locate project → 2. Discover screens → 3. Read reference mapping → 4. Read & convert each screen → 5. Assemble preview.html → 6. Write file → 7. Open in browser

### Step 1 — Locate project
Determine the working directory:
…Read the whole file at its exact version.
How to install
mdr add microsoft/power-platform-skills/preview-screens@sha256:7d8e9a1eee7d1c60The line at the top of this page pins the label git:20261015.8a10052, 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.
