SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and assets (resource) components.

What problem does it solve? Writing a PRD that downstream teams can actually build from is hard: requirements end up vague, assumptions go unrecorded, and review happens too late. This Skill guides a structured PRD workflow with persistent decision logging, calibrated rigor, and multi-reviewer validation. ## Core Features & Use Cases - Three intent modes: Create a new PRD through facilitated discovery, Update an existing PRD against a change signal, or Validate a PRD against a seven-dimension quality rubric without modifying it. - Persistent run workspace: Every decision, change, and assumption is appended to a memlog, with an addendum capturing depth that belongs downstream, so sessions can stop and resume without losing context. - Reviewer gate and synthesis: Parallel reviewer subagents critique the PRD and their findings are consolidated into an HTML and Markdown validation report with severity-tiered findings. - Use Case: A product manager needs a launch-grade PRD for a new consumer feature. The Skill runs a brain dump, calibrates stakes, drafts the PRD with tagged assumptions, runs reviewer subagents, and finalizes a polished document with an assumptions index. ## Quick Start Ask the assistant to help you create a PRD for your product idea and answer the discovery questions it asks.

FAQPage Schema
How do I create a PRD with an AI assistant?▼

Invoke the skill with your product idea or existing inputs such as briefs or research. It runs a brain dump, calibrates stakes, offers a fast or coaching working mode, then drafts the PRD with tagged assumptions and finalizes it through a reviewer pass.

How do I validate an existing PRD for quality?▼

Use the Validate intent, which critiques the PRD without changing it. A rubric-walker subagent assesses seven dimensions such as decision-readiness and done-ness clarity, and findings are synthesized into HTML and Markdown validation reports.

Can I resume an unfinished PRD drafting session?▼

Yes. Each run binds a workspace folder containing the PRD, an addendum, and an append-only memlog of every decision. On a new invocation the skill scans for in-progress runs and offers to resume rather than starting over.

Does the PRD template work for regulated or enterprise products?▼

The template has an essential spine plus an adapt-in menu with clusters for enterprise, regulated, developer, and hardware products. Teams can also override the template, rubric, and reviewers through team or user TOML files.

What happens to PRD content that does not fit the main document?▼

Depth such as rejected alternatives, technical mechanisms, and sizing data is captured in an addendum file during the conversation. This keeps the PRD focused while preserving material for downstream architecture or UX documents.
