generate-prd

Generate detailed, actionable Product Requirements Documents (PRDs) for new features. Guide users through clarifying questions, then produce specifications suitable for implementation by developers or AI agents.

Important: This skill creates PRDs only—it does NOT begin implementation.

<quick_start>

Ask 3-5 clarifying questions with lettered options (A, B, C, D)
Generate structured PRD based on answers
Save to tasks/prd-[feature-name].md </quick_start>

Ask 3-5 essential questions using AskUserQuestion tool. Cover:

Problem/Goal: What problem does this solve? Who benefits?
Core Functionality: What are the must-have features?
Scope/Boundaries: What is explicitly NOT included?
Success Criteria: How will we know this worked?

Each question should have 3-4 concrete options (A, B, C, D format) plus "Other" for custom input.

Create the PRD document with these sections:

Introduction/Overview – Brief feature description and problem statement
Goals – Specific, measurable objectives
User Stories – Each with title, description, and verifiable acceptance criteria
Functional Requirements – Numbered explicitly (FR-1, FR-2, etc.)
Non-Goals – Clear scope boundaries
Design Considerations – UI/UX requirements (if applicable)
Technical Considerations – Constraints and dependencies (if applicable)
Success Metrics – Measurable outcomes
Open Questions – Remaining clarifications needed

Save the PRD to: `tasks/prd-[feature-name].md`

Use kebab-case for feature name (e.g., prd-user-authentication.md).

Avoid jargon or explain it. Provide concrete examples. A junior developer should understand every requirement without additional context. Acceptance criteria must be testable and specific.

Good: "Login button redirects to /dashboard on success" Bad: "Login works correctly"

Every UI-focused user story MUST include this acceptance criterion: `"Verify in browser using dev-browser skill"` Each user story should be small enough to implement in one session. If a story feels too large, break it into smaller stories.

# PRD: {{Feature Name}}

## 1. Introduction

{{Brief description of the feature and the problem it solves}}

## 2. Goals

- {{Goal 1: Specific, measurable objective}}
- {{Goal 2: Specific, measurable objective}}

## 3. User Stories

### US-1: {{Story Title}}
**As a** {{user type}}, **I want** {{feature}} **so that** {{benefit}}.

**Acceptance Criteria:**
- {{Specific, testable criterion}}
- {{Specific, testable criterion}}
- Verify in browser using dev-browser skill (for UI stories)

### US-2: {{Story Title}}
...

## 4. Functional Requirements

- **FR-1**: {{Explicit requirement}}
- **FR-2**: {{Explicit requirement}}
- **FR-3**: {{Explicit requirement}}

## 5. Non-Goals

- {{What this feature explicitly does NOT do}}
- {{Scope boundary}}

## 6. Design Considerations

{{UI/UX requirements, wireframe references, design patterns}}

## 7. Technical Considerations

{{Constraints, dependencies, integration points, performance requirements}}

## 8. Success Metrics

- {{Measurable outcome 1}}
- {{Measurable outcome 2}}

## 9. Open Questions

- [ ] {{Unresolved question needing clarification}}

</prd_template>

**Good:** - "Search results display within 2 seconds" - "Error message shows 'Invalid email format' for malformed input" - "Clicking 'Save' disables button and shows spinner until complete"

Bad:

"Search is fast"
"Shows appropriate error messages"
"Good UX on save"

- **FR-1**: System shall validate email format using RFC 5322 pattern - **FR-2**: Password must be minimum 8 characters with at least one number - **FR-3**: Session expires after 30 minutes of inactivity

<success_criteria> PRD is complete when:

3-5 clarifying questions were asked and answered
All 9 PRD sections are filled with concrete content
User stories have verifiable acceptance criteria
UI stories include browser verification criterion
Functional requirements are numbered (FR-1, FR-2, etc.)
Non-goals clearly define scope boundaries
Document saved to tasks/prd-[feature-name].md
No implementation has begun (PRD only) </success_criteria>
