Use when the user wants an app idea turned into a Product Requirements Document (PRD) committed to a repo — "create a PRD", "/app-prd", "turn this idea into a PRD", or a raw idea dump ending with "save it to this repo". Produces a complete, section-numbered PRD.md landed via worktree + PR, bootstrapping an empty repo if needed. Stage 1 of the new-app-pipeline.
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
# app-prd Turn a raw idea dump into a complete, implementable PRD committed to the target repo. Write it so a cold agent could implement from it plus nothing else. ## Input - An idea dump: features, pricing, constraints, platform choices — usually messy prose. Optionally a target repo (defaults to the current checkout). - If no repo exists yet and the user named one, offer `gh repo create <name> --private` before proceeding. ## Steps ### 1. Check repo state `git status`, `git log --oneline -3`, `git remote -v`, `git ls-remote origin`. Three cases: - **Normal repo**: proceed with the standard worktree + PR flow. - **Empty repo with remote** (no commits anywhere): bootstrap first. Create `main`, one **empty** initial commit (`git commit --allow-empty -m "Initial commit"` + attribution footer), push. Never put the PRD itself in the bootstrap commit. - **No repo/remote**: confirm repo creation with the user. ### 2. Draft `PRD.md` Structure (adapt section names to the product, keep the skeleton): 1. Header table — product name, repo, platforms, status (**mark the MVP scope explicitly**, e.g. "Draft v0.1 — MVP scope"), last-updated date. …

How to install
mdr add richkuo/rk-skills/app-prd@sha256:7f3665c1dc92732bThe line at the top of this page pins the label git:20261006.4c6da76, 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.
