PRD Generator

Create right-sized Product Requirements Documents that solo devs and small teams can actually use.

Why This Exists

Generates lean PRDs with enough structure to guide development without enterprise bloat.

Input Requirements

This skill works best with upstream context from:

• problem-framing output (problem statement, target user, JTBD, assumptions)
• user-modeling output (personas, scenarios)
• solution-scoping output (feature priorities, MVP boundaries)

Can also work from scratch if user provides enough context about their idea.

Workflow

Step 1: Gather Context

If upstream artifacts exist, ingest them. If not, ask for:

• What are you building?
• Who is it for?
• What problem does it solve?
• What's the MVP scope?

Step 2: Fill Gaps

Check for missing elements and ask targeted questions:

Missing Element	Question
Success metrics	"How will you know this worked? What would you measure?"
Feature priorities	"If you could only ship one thing, what would it be?"
Constraints	"Any technical constraints? Timeline? Budget?"
Non-goals	"What are you explicitly NOT building?"

Keep it conversational—don't interrogate.

Step 3: Generate PRD

Use the output format below. Adapt sections based on project complexity.

Output Format

Automatically save the output to design/05-prd.md using the Write tool while presenting it to the user.

# PRD: [Project Name]

## Overview
[2-3 sentences: what this is and why it matters]

## Problem Statement
[One clear sentence: WHO has WHAT problem WHEN]

## Target User
[Specific description of primary user]

**Characteristics:**
- [Key trait 1]
- [Key trait 2]
- [Key trait 3]

## Goals & Success Metrics

| Goal | Metric | Target |
|------|--------|--------|
| [Goal 1] | [How measured] | [Success threshold] |
| [Goal 2] | [How measured] | [Success threshold] |

## User Stories

### Must Have (MVP)
- As a [user], I want to [action] so that [outcome]
- As a [user], I want to [action] so that [outcome]
- As a [user], I want to [action] so that [outcome]

### Should Have (v1.1)
- As a [user], I want to [action] so that [outcome]
- As a [user], I want to [action] so that [outcome]

### Could Have (Future)
- As a [user], I want to [action] so that [outcome]

## Features

### [Feature 1 Name]
**Priority:** Must Have
**Description:** [What it does]
**User value:** [Why it matters]
**Acceptance criteria:**
- [ ] [Criterion 1]
- [ ] [Criterion 2]
- [ ] [Criterion 3]

### [Feature 2 Name]
**Priority:** Must Have
**Description:** [What it does]
**User value:** [Why it matters]
**Acceptance criteria:**
- [ ] [Criterion 1]
- [ ] [Criterion 2]

### [Feature 3 Name]
**Priority:** Should Have
[Same structure]

## Scope

### In Scope (MVP)
- [What you're building]
- [What you're building]

### Out of Scope
- [What you're NOT building]
- [What you're NOT building]

### Future Considerations
- [What might come later]

## Assumptions & Risks

### Assumptions
- [Assumption 1]
- [Assumption 2]

### Risks
| Risk | Impact | Mitigation |
|------|--------|------------|
| [Risk 1] | [High/Med/Low] | [How to address] |
| [Risk 2] | [High/Med/Low] | [How to address] |

## Technical Considerations
[Optional — include only if relevant]
- **Platform:** [Web/mobile/desktop]
- **Key integrations:** [APIs, services]
- **Data:** [Storage, persistence needs]
- **Constraints:** [Performance, security, compliance]

## Open Questions
- [Anything still unresolved]
- [Decisions needed before development]

## Appendix
[Optional — link to research, competitive analysis, wireframes]

Adaptation Guidelines

For simple projects (weekend build):

• Skip Technical Considerations
• Collapse User Stories into Features
• Minimal Risks section
• 1-2 pages total

For medium projects (side project, MVP):

• Full structure as shown
• 2-4 pages total

For complex projects (startup MVP, team project):

• Add more detail to Features
• Expand Technical Considerations
• Include Appendix with research
• 4-6 pages total

Writing Guidelines

• Be specific, not generic — "Users can filter tasks by due date" not "Users can filter tasks"
• Acceptance criteria are testable — Can you verify yes/no if it's done?
• Priorities are honest — If everything is "Must Have," nothing is
• Out of Scope is explicit — Prevents scope creep later

Handoff

After presenting the PRD, ask:

"Want to move to /ux-specification for detailed flows and screens, or go straight to /prompt-export?"
