Generate high-quality Product Requirements Documents (PRDs) for software systems and AI-powered features. Includes executive summaries, user stories, technical specifications, and risk analysis.
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
# Product Requirements Document (PRD) ## Overview Design comprehensive, production-grade Product Requirements Documents (PRDs) that bridge the gap between business vision and technical execution. This skill works for modern software systems, ensuring that requirements are clearly defined. ## When to Use Use this skill when: - Starting a new product or feature development cycle - Translating a vague idea into a concrete technical specification - Defining requirements for AI-powered features - Stakeholders need a unified "source of truth" for project scope - User asks to "write a PRD", "document requirements", or "plan a feature" --- ## Operational Workflow ### Phase 1: Discovery (The Interview) Before writing a single line of the PRD, you **MUST** interrogate the user to fill knowledge gaps. Do not assume context. **Ask about:** - **The Core Problem**: Why are we building this now? - **Success Metrics**: How do we know it worked? - **Constraints**: Budget, tech stack, or deadline? ### Phase 2: Analysis & Scoping Synthesise the user's input. Identify dependencies and hidden complexities. - Map out the **User Flow**. - Define **Non-Goals** to protect the timeline. …

How to install
mdr add marielynneblock/arcanum-artifex/prd@sha256:85668a549b7d205cThe line at the top of this page pins the label git:20260710.0115f49, 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.
