Write a concise PRD or implementation brief from current context, separating problem, solution, user stories, decisions, testing, rollout, and out of scope. Use when the user asks for a PRD, product brief, implementation brief, or spec handoff.
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
# PRD Writer ## Goal Create a clear product or implementation brief that preserves decisions, unresolved questions, scope, validation, and non-goals. ## When to use - The user asks for a PRD, implementation brief, product spec, or handoff spec. - Current conversation context needs to become a durable planning artifact. - Engineering, product, validation, and rollout expectations need one shared document. ## When not to use - The user only needs an ADR for a narrow repo-level decision. - The task is ready for implementation and does not need a planning artifact. - The user asks for a marketing document rather than product or engineering scope. ## Inputs to inspect - Current conversation, existing specs, issues, roadmap items, ADRs, and domain docs. - User goals, constraints, target users, non-goals, and known decisions. - Existing validation commands and release process when relevant. ## Workflow 1. Identify the audience and artifact type: PRD, implementation brief, or handoff spec. 2. Separate problem, goals, non-goals, proposed solution, decisions, and open questions. 3. Write user stories or use cases only when they clarify behavior. …

How to install
mdr add stark-ai-de/agent-skills/prd-writer@sha256:100e8f4d4da78989The line at the top of this page pins the label v0.1.0, 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.
