PRD Creation Skill

Purpose

Guide Product Managers through creating comprehensive, industry-standard Product Requirements Documents (PRDs) that serve as the foundation for superior technical specifications.

Industry-Standard PRD Frameworks

This skill synthesizes best practices from:

1. Amazon's PR/FAQ (Press Release / Frequently Asked Questions)

• Start with the customer and work backward
• Write the press release first (forces clarity on customer value)
• Anticipate and answer tough questions upfront

2. Google's PRD Template

• Clear problem statement and goals
• User stories with acceptance criteria
• Success metrics (OKRs)
• Technical constraints and dependencies

3. Intercom's Job Stories

• When [situation], I want to [motivation], so I can [expected outcome]
• Focus on context and causality, not just user roles

4. Pragmatic Institute's Requirements Framework

• Market problems (not solutions)
• Personas and use cases
• Prioritization criteria
• Success metrics

PRD Creation Workflow

Step 1: Gather Context

Before starting, collect:

1. Product Context:

   • Read docs/product/01_Product_Vision/product-vision.md
   • Read docs/product/01_Product_Vision/target-users.md
   • Read relevant docs/product/06_OKRs/ for current quarter

2. Feature Context:

   • What problem are we solving?
   • Who requested this? (User feedback, leadership, competitive pressure?)
   • What's the urgency/priority?

3. Technical Context:

   • Read docs/architecture/README.md for current architecture state (what exists vs what's needed)
   • Read docs/architecture/04_deployment_environments/production.md and staging.md (verify infrastructure status)
   • Read docs/product/STATUS.md for feature completion status (identify recently completed features)
   • Search git log for recent feature completions (e.g., "Feature 003 complete", "deployed", "APPROVED")
   • Search knowledge base for similar features
   • Identify dependencies AND verify which are already satisfied vs pending

4. Backlog Source Check (optional):

   • Search GitHub Issues with stage:discover label for validated ideas ready for PRD
   • If validated ideas exist, present them to the user as candidates
   • If user selects a backlog item, populate source.idea_id in PRD frontmatter:

     source:           # Automatically populated from GitHub Issue
       idea_id: null   # GitHub Issue number — always equals prd.number
       story_id: null  # Deprecated — user stories now stored in GitHub Issue body
     

   • source.idea_id is automatically set from the GitHub Issue number (resolved in Step 1 of /aod.define) and always equals prd.number
   • If user starts fresh (no backlog item selected), idea_id is still set to the GitHub Issue number

Step 1b: Incorporate GitHub Issue Content

If a GitHub Issue was selected as the source (Step 1, Backlog Source Check), read its full body — especially ## Detail, ## Stories, ## Interface Contract, and ## Definition of Done sections. This content is the primary input for the PRD:

• Issue stories → PRD User Stories section (preserve verbatim, convert to Job Story format)
• Issue acceptance criteria → PRD Acceptance Criteria (preserve verbatim)
• Issue interface contract → PRD Functional Requirements / Integration Requirements
• Issue Definition of Done → PRD Success Criteria / Scope boundaries

Do NOT generate these sections from scratch when the GitHub Issue already provides them. Build on what exists — refine, expand, and structure into PRD format, but never drop or summarize away detail that the user provided.

Step 2: Draft PRD Sections

Work through the PRD structure systematically, incorporating GitHub Issue content where available:

## Recommended Order:
1. Executive Summary (write last, but placeholder early)
2. Strategic Alignment (ensures feature fits vision)
3. Target Users & Personas (who benefits?)
4. User Stories (what do they need?)
5. User Experience Requirements (how do they use it?)
6. Functional Requirements (what does it do?)
7. Non-Functional Requirements (how well does it do it?)
8. Success Metrics (how do we measure success?)
9. Scope & Boundaries (what's in/out?)
10. Timeline & Milestones (when does it happen?)
11. Risks & Dependencies (what could go wrong?)
12. Open Questions (what don't we know?)
13. References (supporting docs)
14. Executive Summary (revisit with full context)

Step 3: Validate Completeness

Use this checklist:

## PRD Quality Checklist

### Clarity
- [ ] Problem statement is clear to non-technical stakeholders
- [ ] User stories use plain language, not jargon
- [ ] Success metrics are specific and measurable
- [ ] Scope boundaries are explicit (in scope vs out of scope)

### Completeness
- [ ] All major user flows documented
- [ ] Edge cases identified and handled
- [ ] Non-functional requirements specified
- [ ] Dependencies and risks identified
- [ ] Open questions captured

### Alignment
- [ ] Aligns with product vision
- [ ] Supports current quarter OKRs
- [ ] Fits roadmap timeline
- [ ] Serves target user personas
- [ ] References customer journey maps

### Feasibility
- [ ] Technical requirements are realistic
- [ ] Timeline accounts for dependencies
- [ ] Team capacity is available
- [ ] Risks have mitigation plans
- [ ] Assumptions are documented and validated

### Traceability
- [ ] Links to product vision
- [ ] Links to OKRs
- [ ] Links to roadmap
- [ ] Links to user stories
- [ ] Links to constitution for constraints

Step 4: Get Feedback

Governance Context Loading (Lazy Load):

Before invoking Triad review, load governance rules just-in-time:

1. Validate file existence: Check that .aod/memory/constitution.md exists
   • If missing, fail immediately with error: "Governance file not found: .aod/memory/constitution.md - cannot proceed with Triad review"
2. Load governance rules: Read .aod/memory/constitution.md for constraints and principles
3. Proceed with review: Only after governance context is loaded

Review Process:

1. Self-review: Walk through PRD as if you're seeing it fresh
2. Stakeholder review: Share with architect, team-lead for technical feasibility
3. User validation: If possible, validate assumptions with actual users
4. Revision: Incorporate feedback, answer open questions
5. Approval: Get sign-offs from required stakeholders

Step 5: Handoff to Spec Creation

Once PRD is approved:

1. Create spec.md using /aod.spec
2. Provide PRD as input: Reference PRD location in spec creation
3. Validate alignment: Ensure spec.md reflects PRD requirements
4. Sign-off on spec: Product Manager approves spec.md before implementation

Integration with Triad Workflow

PRD → Spec Mapping

PRD Section	Maps to Spec Section
Problem Statement	Background / Motivation
User Stories	User Stories / Use Cases
Functional Requirements	Functional Requirements
Non-Functional Requirements	Non-Functional Requirements
Success Metrics	Success Criteria
Scope & Boundaries	Scope / Out of Scope
Timeline	Implementation Plan
Risks & Dependencies	Risks / Constraints

Spec → Plan Validation

Product Manager validates plan.md ensures:

• Timeline aligns with PRD milestones
• Technical approach serves user stories
• Architecture supports non-functional requirements
• Tasks prioritization reflects user value

Plan → Tasks Validation

Product Manager validates tasks.md ensures:

• Task prioritization matches product priorities
• MVP scope matches PRD in-scope items
• Task descriptions reference user value
• Dependencies align with PRD dependencies

---

Common PRD Pitfalls

❌ Don't Do This

Vague Problem Statements:

• Bad: "Users have trouble with authentication"
• Good: "Users abandon sign-up flow at 40% rate due to password complexity requirements that don't match their mental model"

Solution-Focused User Stories:

• Bad: "As a user, I want a JWT refresh mechanism"
• Good: "When my session is active and my auth token is about to expire, I want to stay logged in automatically, so I don't lose my work mid-task"

Unmeasurable Success Metrics:

• Bad: "Users will be happier"
• Good: "NPS increases from 32 to 45, CSAT for auth flow increases from 6.2 to 8.5"

Missing Acceptance Criteria:

• Bad: "User can search"
• Good: "Given 1000 documents indexed, when user searches 'postgres connection', then results return in <2s with relevant docs ranked first"

✅ Do This

Clear, User-Focused Problem Statements:

• Start with user pain, quantify impact, explain why now

Context-Rich Job Stories:

• When [situation], I want to [action], so I can [outcome]
• Focus on causality and context

SMART Success Metrics:

• Specific, Measurable, Achievable, Relevant, Time-bound

Testable Acceptance Criteria:

• Given-When-Then format for every user story

---

Common Rationalizations

Rationalization	Reality
"Strategic Alignment is fluff — I'll skip vision and OKR links"	Step 1 (line 595) requires reading product-vision.md and OKRs; the PRD structure (line 73) reserves a section for both.
"I drafted from scratch — the GitHub Issue body is just a summary"	Step 1b (line 626) treats Issue stories, ACs, and DoD as primary input; do NOT regenerate or summarize away detail.
"Sign-offs can land asynchronously after hand-off to /aod.spec"	Step 4 (line 712) requires sign-offs before approval; Step 5 (line 721) gates handoff on approved status.
"Open Questions belong in spec.md — I'll leave the PRD section empty"	PRD Structure (line 480) reserves the Open Questions section; Quality Checklist (line 677) requires capturing them.
"Architect baseline review is for infrastructure PRDs only — I'll skip"	Step 1 (line 607) mandates reading architecture/README and deployment-environments docs before drafting the PRD.

Red Flags

• Agent invokes Triad review without loading .aod/memory/constitution.md per Step 4 (line 707).
• Agent's PRD lacks the Approval Status table (line 555) populated for all three Triad roles.
• Agent skips Step 1 git log search (line 610) for recent feature completions and reinvents existing work.
• Agent declares the PRD READY while Quality Checklist Alignment items (line 679) remain unchecked.
• Agent omits source.idea_id from frontmatter despite a backlog Issue selection per Step 1 (line 619).
• Agent maps PRD → Spec sections without consulting the table at line 734, dropping required sections.
