prd-writing-standards SKILL.md skillA

prd-writing-standards from ensodynamics/enso-method is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add ensodynamics/enso-method/prd-writing-standards@git:20261103.fd289f9

Pins git:20261103.fd289f9 in mdr.lock. Pin the fingerprint instead.

Write or check a PRD (Product Requirements Document), the requirements a technical design is then built from. Skimmable — clear business context and testable outcomes without implementation details, invented responsibilities, or step-by-step instructions. Use when the user describes something to build and no PRD exists yet, or to bring an existing PRD up to this standard.

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.

# PRD Writing Standards

Guidelines for writing PRDs.

---

## What Is a PRD?

A PRD (Product Requirements Document) is a high-level description of a product change or capability we're delivering. It answers the questions **"What are we delivering?"** and **"Why are we doing it?"** in plain business language.

A PRD should be understandable by product managers, stakeholders, and anyone who needs to know what we're delivering without diving into technical details.

## Before You Write: Is This One PRD?

A PRD in `docs/prds/` is a medium body of work that ends with something finished that can be promoted to production. It is not the whole application; a bounded change in `docs/changes/` uses the same document set and can be as small as one fix (see "Document Storage Convention"). Before drafting, check the source material against the PRD-sized test in `initiative-breakdown` (Step 2). The usual sign it fails: the work would take many phases before anything finished reaches production, or it bundles several outcomes that could each ship on their own. When it fails, run `initiative-breakdown` first. It cuts the idea into planned PRDs, and this skill then writes each of them. The…

How to install

The exact contents, by fingerprint
mdr add ensodynamics/enso-method/prd-writing-standards@sha256:428bea1ae0b97707

The line at the top of this page pins the label git:20261103.fd289f9, 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.
