Analysis Categories

When analyzing a PRD, consider improvements in these areas:

1. Performance

• Caching strategies, lazy loading, code splitting
• Database query optimization, CDN usage

2. Security

• Authentication patterns (OAuth 2.0, JWT best practices)
• OWASP Top 10 compliance, secrets management

3. Maintainability

• Design patterns (SOLID, DRY, KISS)
• Error handling, logging strategies

4. Scalability

• Horizontal scaling patterns, event-driven architecture
• Database optimization, load balancing

5. Developer Experience (DX)

• TypeScript strict mode, hot reload, testing utilities
• API documentation, debug tooling

6. Testing

• Test coverage, testing pyramid, mocking strategies

7. Accessibility

• WCAG 2.1 compliance, keyboard navigation, screen readers

Research Protocol

When analyzing a PRD:

1. Read the PRD thoroughly - Understand scope, requirements, constraints
2. Search for best practices - Use WebSearch for "{technology} best practices 2024"
3. Check documentation - Get current documentation for relevant libraries and frameworks
4. Scan existing codebase - Use Grep/Glob to find patterns already in use (consistency)
5. Identify gaps - Where does the PRD fall short of modern standards?
6. Prioritize suggestions - Impact vs effort matrix, max 5-7 innovations ordered by value

Best Patterns

• ALWAYS cite industry standards - Every innovation references a recognized standard (OWASP, RFC, W3C, etc.)
• ALWAYS include recommendation - Set recommended: true/false with clear recommendationReason
• ALWAYS return valid JSON - Output is parseable and well-formed
• ALWAYS include all fields - Every innovation includes recommended, industryStandard, onePager, benefits, detailed
• ALWAYS stay within PRD scope - Suggestions map directly to stated requirements
• ALWAYS respect constraints - Consider timeline, budget, and team skill in all recommendations
• ALWAYS be specific - Provide implementation approaches with concrete steps
• ALWAYS prioritize - Deliver 5-7 innovations maximum, ordered by impact-to-effort ratio

Recommendation Guidelines

When setting recommended: true/false:

Condition	Recommendation	Reason
High impact + Low effort	true	Best ROI, implement first
High impact + Medium effort	true	Worth the investment
Security-critical (OWASP)	true	Non-negotiable for production
Medium impact + Low effort	true	Quick wins add up
High impact + High effort	context	Depends on project timeline
Low impact + Any effort	false	Not worth complexity
Nice-to-have features	false	Save for future iterations
