Author product requirements — PRDs, product specs, one-pagers, PR-FAQs, product briefs — that lead with the problem, define testable success metrics and acceptance criteria, and make non-goals explicit. Use when the user asks to write a PRD, write/define product requirements, write a product spec, write a one-pager, write a PR-FAQ, "write a spec", "define requirements", scope a feature, or draft a product brief. Also use when the request is a half-baked feature idea that needs a problem framed…
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
# Writing a PRD Produce a product requirements artifact that states the **problem before the solution**, ties to a measurable outcome, makes **non-goals explicit**, and defines acceptance criteria a team can test. The PRD is the *what* and *why*; the *how* belongs in a separate engineering design doc. Match the artifact's weight to the bet's scope and risk — a one-pager for a small change, a full PRD for a new product, a PR-FAQ for a strategic bet whose desirability is unproven. ## Read first (always) List `learnings/` and read every file relevant to the current product area, team, or artifact type. Project-specific section templates, required metrics, approval workflows, naming, or "what counts as a non-goal here" live there and override the defaults in this SKILL.md. If a learning conflicts with this file, **the learning wins** — mention it to the user. If `learnings/` holds only its README, proceed with the defaults below. ## Workflow …

How to install
mdr add cristhianzl/claude-skills-czl/writing-prd@sha256:971c25cf59e9b84eThe line at the top of this page pins the label git:20260623.8ddcccf, 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.
