Usage Examples
Example 1: New Feature Product Requirements Document
@prd-writer Create PRD for "Smart Recommendations" feature in e-commerce platform using ML
# Expected Process:
# 1. Agent gathers requirements from stakeholders and user research
# 2. Agent defines detailed user stories with acceptance criteria
# 3. Agent outlines technical requirements (ML model, data pipeline, API specs)
# 4. Agent specifies success metrics and KPIs
# Expected Output:
# - Feature Overview: Clear description of recommendation engine and value proposition
# - User Stories: 8-12 detailed scenarios with acceptance criteria (e.g., "As a shopper, I want personalized product recommendations so I discover items I'll love")
# - Technical Requirements: API specifications, data model, ML integration, performance targets
# - Success Metrics: Click-through rate on recommendations, conversion lift, user engagement
# - Timeline: Phased rollout plan with milestones
Example 2: API Endpoint Specification PRD
@prd-writer Write comprehensive PRD for new REST API endpoints for user profile management
# Process:
# - Step 1: Define API requirements and use cases (create, read, update, delete profiles)
# - Step 2: Specify request/response formats with JSON schemas
# - Step 3: Document authentication (OAuth 2.0) and authorization rules
# - Step 4: Define comprehensive error handling and edge cases
# Output Format:
# - API Specification: Complete endpoint documentation (GET /users/:id, PUT /users/:id, etc.)
# - Request/Response Schemas: Detailed JSON structure with field descriptions
# - Authentication: OAuth 2.0 implementation requirements
# - Error Codes: Comprehensive error handling (400, 401, 403, 404, 429, 500)
# - Integration Guide: Example requests, responses, and SDK code snippets
Example 3: Third-Party Integration Requirements
@prd-writer Document requirements for Stripe payment gateway integration
# How Agent Handles:
# - Recognition: Identifies integration scope (payment processing, subscription management, webhooks)
# - Requirements Mapping: Maps business requirements to Stripe API capabilities
# - Deliverables: Integration PRD with complete workflow, data mapping, webhook handling, error scenarios
# - Special Considerations: PCI compliance requirements, testing strategy, rollback plan
Remember: Great PRDs turn ambiguous ideas into clear, actionable requirements that teams can build with confidence. Every requirement must be testable, traceable, and tied to user value.
