PRD Creation Skill

Purpose: Guide PRD document creation following the standard template Trigger: When EA agent creates or updates a PRD document Output: Well-structured PRD ready for story extraction

Template Reference

ALWAYS read the template before creating a PRD:

templates/prd-template.md

The template contains:

• Required YAML frontmatter fields
• All 10 standard sections
• Field placeholders and formatting rules
• Template rules (comments at bottom)

Workflow

1. Read the template:

   • Load templates/prd-template.md
   • Note all required sections and frontmatter fields

2. Gather requirements:

   • Extract goals and scope from user prompt
   • Identify functional and non-functional requirements
   • Clarify ambiguities via HITL loop (AskUserQuestion)

3. Draft PRD sections:

   • Follow template section order (1-10)
   • Use tables for structured data (requirements, risks, decisions)
   • Keep descriptions concise (2-3 sentences per section intro)

4. Validate structure:

   • Run validation checklist (see below)
   • Fix any missing or malformed sections

5. Save PRD:

   • Write to {projectFolder}/prd.md
   • Ensure frontmatter is complete

6. Pass validation gate:

   • Spawn reviewer agent for PRD validation
   • On FAIL: Address issues and retry (max 3 attempts)
   • On PASS: Proceed to story extraction

PRD Structure (10 Sections)

Validation Checklist

Run this checklist before marking PRD complete:

Frontmatter

• epic_id present (format: {app}-{epic} e.g., msm-aut)
• title present
• version present (start at "1.0")
• status present (draft | in-review | approved)
• created date present (YYYY-MM-DD)
• updated date present (YYYY-MM-DD)
• owner set to "enterprise-architect-agent"

Required Sections

• Section 1: Executive Summary has overview + goal
• Section 2: Problem Statement has current state + issues table
• Section 3: Solution Overview has target state + principles table
• Section 4: Requirements has FR and NFR tables with IDs
• Section 5: Scope has both in-scope and out-of-scope lists
• Section 6: Epic Summary has epic table (NO user story details)
• Section 7: Success Criteria has technical requirements + verification
• Section 8: Risks has risk table with mitigations
• Section 9: Dependencies lists external and internal
• Section 10: Design Decisions has decision table

Content Rules

• Requirements use ID format: FR-001, NFR-001
• Priority values are P0, P1, or P2 only
• Epic summary shows counts, NOT story details
• No user story acceptance criteria in PRD
• Tables properly formatted with headers

Validation Gate

After PRD is written and self-validated, spawn external reviewer for quality gate.

Spawn: core-claude-plugin:generic:reviewer

Expected Output:

{
  "result": "PASS" | "FAIL",
  "issues": ["issue description", ...]
}

Gate Logic:

1. On PASS: Continue to next phase (story extraction)
2. On FAIL: Return issues to enterprise-architect agent
   • EA addresses each issue in issues[] array
   • EA rewrites/updates PRD sections as needed
   • Re-run validation gate (loop until PASS)

Maximum Retries: 3 attempts before escalating to human reviewer

Key Rules

Example

Input: User requests "Build authentication API"

PRD Creation:

1. EA reads template from templates/prd-template.md
2. EA drafts:
   • Section 1: "Implement secure user authentication..."
   • Section 4: FR-001 Login endpoint, FR-002 Logout endpoint...
   • Section 6: "| E01 | Authentication | 5 | 15 |"
3. EA validates against checklist
4. EA saves to docs/epics/msm-aut-auth-api/prd.md

Output: Complete PRD with all 10 sections, ready for story extraction

Integration

Called by: requirements-phase, /architect command, /build command Calls: Read tool (for template), Write tool (for saving), core-claude-plugin:generic:reviewer (validation gate) References:

• /skill user-story-template - For story extraction (separate phase)
• /skill save-prd - For persisting approved PRD artifacts

Next step: After passing validation gate, story extraction using /skill user-story-template
