PRD Generator

Overview

Generate comprehensive, well-structured Product Requirements Documents (PRDs) that follow industry best practices. This skill helps product managers create clear, actionable requirements documents that align stakeholders and guide development teams.

Core Workflow

When a user requests to create a PRD (e.g., "create a PRD for a user authentication feature"), follow this workflow:

Step 1: Gather Context

Before generating the PRD, collect essential information through a discovery conversation:

**Required Information:**

• **Feature/Product Name**: What are we building?
• **Problem Statement**: What problem does this solve?
• **Target Users**: Who is this for?
• **Business Goals**: What are we trying to achieve?
• **Success Metrics**: How will we measure success?
• **Timeline/Constraints**: Any deadlines or limitations?

**Discovery Questions to Ask:**

1. What problem are you trying to solve?
2. Who is the primary user/audience for this feature?
3. What are the key business objectives?
4. Are there any technical constraints we should be aware of?
5. What does success look like? How will you measure it?
6. What's the timeline for this feature?
7. What's explicitly out of scope?

**Note:** If the user provides a detailed brief or requirements upfront, you can skip some questions. Always ask for clarification on missing critical information.

Step 2: Generate PRD Structure

Use the standard PRD template from `references/prd_template.md` to create a well-structured document. The PRD should include:

1. **Executive Summary** - High-level overview (2-3 paragraphs) 2. **Problem Statement** - Clear articulation of the problem 3. **Goals & Objectives** - What we're trying to achieve 4. **User Personas** - Who we're building for 5. **User Stories & Requirements** - Detailed functional requirements 6. **Success Metrics** - KPIs and measurement criteria 7. **Scope** - What's in and out of scope 8. **Technical Considerations** - Architecture, dependencies, constraints 9. **Design & UX Requirements** - UI/UX considerations 10. **Timeline & Milestones** - Key dates and phases 11. **Risks & Mitigation** - Potential issues and solutions 12. **Dependencies & Assumptions** - What we're relying on 13. **Open Questions** - Unresolved items

Step 3: Create User Stories

For each major requirement, generate user stories using the standard format:

As a [user type],
I want to [action],
So that [benefit/value].

Acceptance Criteria:
- [Specific, testable criterion 1]
- [Specific, testable criterion 2]
- [Specific, testable criterion 3]

Reference `references/user_story_examples.md` for common patterns and best practices.

Step 4: Define Success Metrics

Use appropriate metrics frameworks based on the product type:

• **AARRR (Pirate Metrics)**: Acquisition, Activation, Retention, Revenue, Referral
• **HEART Framework**: Happiness, Engagement, Adoption, Retention, Task Success
• **North Star Metric**: Single key metric that represents core value
• **OKRs**: Objectives and Key Results

Consult `references/metrics_frameworks.md` for detailed guidance on each framework.

Step 5: Validate & Review

Optionally run the validation script to ensure PRD completeness:

scripts/validate_prd.sh <prd_file.md>

This checks for:

• All required sections present
• User stories follow proper format
• Success metrics are defined
• Scope is clearly articulated
• No placeholder text remains

Usage Patterns

Pattern 1: New Feature PRD

**User Request:** "Create a PRD for adding dark mode to our mobile app"

**Execution:**

1. Ask discovery questions about dark mode requirements 2. Generate PRD using template 3. Create user stories for:

• Theme switching
• Preference persistence
• System-level sync
• Design token updates

4. Define success metrics (adoption rate, user satisfaction) 5. Identify technical dependencies (design system, platform APIs)

Pattern 2: Product Enhancement PRD

**User Request:** "Write requirements for improving our search functionality"

**Execution:**

1. Gather context on current search limitations 2. Identify user pain points and desired improvements 3. Generate PRD with focus on:

• Current state analysis
• Proposed enhancements
• Impact assessment

4. Create prioritized user stories 5. Define before/after metrics

Pattern 3: New Product PRD

**User Request:** "I need a PRD for a new analytics dashboard product"

**Execution:**

1. Comprehensive discovery (market analysis, user research) 2. Generate full PRD with:

• Market opportunity
• Competitive analysis
• Product vision
• MVP scope
• Go-to-market considerations

3. Detailed user stories for core features 4. Phased rollout plan 5. Success metrics aligned with business goals

Pattern 4: Quick PRD / One-Pager

**User Request:** "Create a lightweight PRD for a small bug fix feature"

**Execution:**

1. Generate simplified PRD focusing on:

• Problem statement
• Solution approach
• Acceptance criteria
• Success metrics

2. Skip sections not relevant for small scope 3. Keep document concise (1-2 pages)

PRD Best Practices

Writing Quality Requirements

**Good Requirements Are:**

• **Specific**: Clear and unambiguous
• **Measurable**: Can be verified/tested
• **Achievable**: Technically feasible
• **Relevant**: Tied to user/business value
• **Time-bound**: Has clear timeline

**Avoid:**

• Vague language ("fast", "easy", "intuitive")
• Implementation details (let engineers decide how)
• Feature creep (stick to core requirements)
• Assumptions without validation

User Story Best Practices

**DO:**

• Focus on user value, not features
