Prd

PRD Generator

Create detailed Product Requirements Documents that are clear, actionable, and suitable for implementation.

The Job

1. Receive a feature description from the user
2. Use AskUserQuestion tool to ask 3-5 essential clarifying questions
3. Generate a structured PRD based on answers
4. Save to tasks/prd-[feature-name].md

Important: Do NOT start implementing. Just create the PRD.

Step 1: Clarifying Questions

Use the AskUserQuestion tool to gather requirements interactively. Ask only critical questions where the initial prompt is ambiguous.

Focus on these areas:

• Problem/Goal: What problem does this solve?
• Core Functionality: What are the key actions?
• Scope/Boundaries: What should it NOT do?
• Success Criteria: How do we know it's done?

How to Ask

Use AskUserQuestion with 2-4 questions at a time. Each question should have 2-4 concrete options.

Example tool call:

{
  "questions": [
    {
      "question": "What is the primary goal of this feature?",
      "header": "Goal",
      "options": [
        {"label": "Improve onboarding", "description": "Help new users get started faster"},
        {"label": "Increase retention", "description": "Keep existing users engaged"},
        {"label": "Reduce support", "description": "Decrease tickets and manual help"}
      ],
      "multiSelect": false
    },
    {
      "question": "Who is the target user?",
      "header": "Users",
      "options": [
        {"label": "New users", "description": "Users who just signed up"},
        {"label": "All users", "description": "Everyone regardless of tenure"},
        {"label": "Admin users", "description": "Users with elevated permissions"}
      ],
      "multiSelect": false
    },
    {
      "question": "What scope do you want?",
      "header": "Scope",
      "options": [
        {"label": "MVP (Recommended)", "description": "Minimal viable version, iterate later"},
        {"label": "Full-featured", "description": "Complete implementation upfront"},
        {"label": "Backend only", "description": "Just the API, no UI"},
        {"label": "UI only", "description": "Frontend with mock data"}
      ],
      "multiSelect": false
    }
  ]
}

Tips:

• Users can always select "Other" to provide custom input
• Use multiSelect: true when options aren't mutually exclusive
• Keep headers under 12 characters
• Add "(Recommended)" to the suggested option's label

Step 2: PRD Structure

Generate the PRD with these sections:

1. Introduction/Overview

Brief description of the feature and the problem it solves.

2. Goals

Specific, measurable objectives (bullet list).

3. User Stories

Each story needs:

• Title: Short descriptive name
• Description: "As a [user], I want [feature] so that [benefit]"
• Acceptance Criteria: Verifiable checklist of what "done" means

Each story should be small enough to implement in one focused session.

Format:

### US-001: [Title]
**Description:** As a [user], I want [feature] so that [benefit].

**Acceptance Criteria:**
- [ ] Specific verifiable criterion
- [ ] Another criterion
- [ ] Typecheck/lint passes
- [ ] **[UI stories only]** Verify in browser

Important:

• Acceptance criteria must be verifiable, not vague. "Works correctly" is bad. "Button shows confirmation dialog before deleting" is good.
• For any story with UI changes: Always include "Verify in browser" as acceptance criteria.

4. Functional Requirements

Numbered list of specific functionalities:

• "FR-1: The system must allow users to..."
• "FR-2: When a user clicks X, the system must..."

Be explicit and unambiguous.

5. Non-Goals (Out of Scope)

What this feature will NOT include. Critical for managing scope.

6. Design Considerations (Optional)

• UI/UX requirements
• Link to mockups if available
• Relevant existing components to reuse

7. Technical Considerations (Optional)

• Known constraints or dependencies
• Integration points with existing systems
• Performance requirements

8. Success Metrics

How will success be measured?

• "Reduce time to complete X by 50%"
• "Increase conversion rate by 10%"

9. Open Questions

Remaining questions or areas needing clarification.

Writing for Junior Developers

The PRD reader may be a junior developer or AI agent. Therefore:

• Be explicit and unambiguous
• Avoid jargon or explain it
• Provide enough detail to understand purpose and core logic
• Number requirements for easy reference
• Use concrete examples where helpful

Output

• Format: Markdown (.md)
• Location: tasks/
• Filename: prd-[feature-name].md (kebab-case)

Example PRD

# PRD: Task Priority System

## Introduction

Add priority levels to tasks so users can focus on what matters most. Tasks can be marked as high, medium, or low priority, with visual indicators and filtering to help users manage their workload effectively.

## Goals

- Allow assigning priority (high/medium/low) to any task
- Provide clear visual differentiation between priority levels
- Enable filtering and sorting by priority
- Default new tasks to medium priority

## User Stories

### US-001: Add priority field to database
**Description:** As a developer, I need to store task priority so it persists across sessions.

**Acceptance Criteria:**
- [ ] Add priority column to tasks table: 'high' | 'medium' | 'low' (default 'medium')
- [ ] Generate and run migration successfully
- [ ] Typecheck passes

### US-002: Display priority indicator on task cards
**Description:** As a user, I want to see task priority at a glance so I know what needs attention first.

**Acceptance Criteria:**
- [ ] Each task card shows colored priority badge (red=high, yellow=medium, gray=low)
- [ ] Priority visible without hovering or clicking
- [ ] Typecheck passes
- [ ] Verify in browser

### US-003: Add priority selector to task edit
**Description:** As a user, I want to change a task's priority when editing it.

**Acceptance Criteria:**
- [ ] Priority dropdown in task edit modal
- [ ] Shows current priority as selected
- [ ] Saves immediately on selection change
- [ ] Typecheck passes
- [ ] Verify in browser

### US-004: Filter tasks by priority
**Description:** As a user, I want to filter the task list to see only high-priority items when I'm focused.

**Acceptance Criteria:**
- [ ] Filter dropdown with options: All | High | Medium | Low
- [ ] Filter persists in URL params
- [ ] Empty state message when no tasks match filter
- [ ] Typecheck passes
- [ ] Verify in browser

## Functional Requirements

- FR-1: Add `priority` field to tasks table ('high' | 'medium' | 'low', default 'medium')
- FR-2: Display colored priority badge on each task card
- FR-3: Include priority selector in task edit modal
- FR-4: Add priority filter dropdown to task list header
- FR-5: Sort by priority within each status column (high to medium to low)

## Non-Goals

- No priority-based notifications or reminders
- No automatic priority assignment based on due date
- No priority inheritance for subtasks

## Technical Considerations

- Reuse existing badge component with color variants
- Filter state managed via URL search params
- Priority stored in database, not computed

## Success Metrics

- Users can change priority in under 2 clicks
- High-priority tasks immediately visible at top of lists
- No regression in task list performance

## Open Questions

- Should priority affect task ordering within a column?
- Should we add keyboard shortcuts for priority changes?
