Write the general-purpose PRD, and the requirements stack around it (one-pager, BRD, PRD, FRD, NFR, business rules, PR FAQ), sized first against the weight ladder in os/WHICH-DOCUMENT.md. Use when a PM needs to write a PRD or any document in that stack for a feature a human engineering team will build, when a draft has a features table with no objective above it or targets nobody agreed to, or when a request for a PRD has nowhere else in this repository to land. Routes away immediately, before…
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
# Write PRD: objectives before features, a kill switch before launch Ask this operating system for a PRD before this release and the router had nothing general enough to hand you: ai-prd assumes the implementer is a model, and every other skill assumed you already knew which document you needed. This skill is the ordinary case: a human engineering team building something real. The moment that stops being true, this skill stops too and hands the whole document to [ai-prd](../ai-prd/SKILL.md), explained below in step 2. Past that fork, it exists to stop three more specific failures: a spec written to avoid doing the discovery work, a features table with no objective above it, and a document that can start work but never says how to stop it. ## Files this skill drives - [../../templates/definition/prd.md](../../templates/definition/prd.md), the primary artifact, run from section 0 (the one-read summary) through section 13 (companion documents), then the sign-off block …

How to install
mdr add rizwanzafaris/product-manager-os/write-prd@sha256:6775b0f413e1d1bcThe line at the top of this page pins the label git:20260919.72235e0, 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.
