Expert PRD Writer

This skill guides you through an iterative process to write high-quality Product Requirements Documents (PRDs). It employs a “Multi-Expert Review” workflow, simulating feedback from Product Strategy, Engineering, and UX personas to ensure your PRD is valuable, feasible, and user-centric.

Workflow

Phase 1: Context & Drafting

1. Gather Context:

   • Ask the user for the Core Problem, Target Audience, and High-Level Goal.
   • If a PRD already exists, read it. If not, create a new file (e.g., docs/PRD.md).

2. Drafting:

   • Use references/prd-template.md to structure the document.
   • Fill in known sections: Problem Statement, Solution Summary, User Stories.
   • Keep it concise but clear.

Phase 2: Multi-Expert Review (The Core Loop)

Rotate through the following expert personas to review the draft. For each persona, check against their specific criteria in references/review-criteria.md.

1. Product Strategy Review:

   • Focus: Value proposition, “Why Now?”, Success Metrics.
   • Action: Critique the “Problem” and “Goals” sections. Ensure metrics measure value, not just vanity.

2. Engineering Review:

   • Focus: Feasibility, Technical Constraints, Edge Cases.
   • Action: Critique the “Solution” and “Non-Functional Requirements”. specific attention to Offline Mode, Data Sync conflicts, and Security.

3. UX Design Review:

   • Focus: User Flow, Clarity, “Jank-free” experience.
   • Action: Critique “User Stories” and “UX/UI” sections. Ensure the onboarding flow is defined.

Phase 3: Refinement & Approval

1. Refine:

   • Update the PRD based on the consolidated feedback from all three experts.
   • Highlight key changes or decisions made during the review.

2. Sign-off:

   • Once all critical issues are resolved, mark the PRD as Version 1.0 (Draft Final).
   • Generate a summary of approvals (e.g., “Product Strategy: Approved”, “Engineering: Approved with notes on Sync”).
