Lesson 6: Introduction to Reusable Intelligence
The Strategic Asset Shift
When AI can generate code instantly, what becomes valuable?
Answer: Captured decision-making expertise (Reusable Intelligence)
Skills vs Subagents
Skills (2-4 decisions, horizontal)
Purpose: Provide consistent guidance across all specs
Examples:
- Input validation patterns
- Error handling standards
- API design principles
Subagents (5+ decisions, vertical)
Purpose: Autonomous reasoning for complex domains
Examples:
- Security review
- Performance optimization
- Architecture decisions
Microservices Analogy
Just like microservices:
- Reusable: Use across multiple projects
- Composable: Combine to solve complex problems
- Single responsibility: Each handles one concern
Key Takeaway
✅ Intelligence is the new strategic asset
✅ Skills for simple patterns (2-4 decisions)
✅ Subagents for complex reasoning (5+ decisions)
