Green Light / Red Light
The skill isn't in using AI; it's in knowing when not to. This is the exact framework for avoiding the 'Dependency Trap'—strategic delegation that keeps your engineering muscles sharp while 10x-ing your speed.
Think of yourself as the Senior Developer (Architect, Judgment, Responsibility) and the AI as your Junior Developer (Speed, Syntax, Pattern-matching). You wouldn't let a junior design your database schema alone—don't let an AI do it either.
The Mental Model: Chef and Prep Cook
A master chef and a prep cook work together. The chef designs the menu and tastes the results; the prep cook chops ingredients at speed. Neither is dispensable, but only one is the chef.
The Division of Labor
- Architectural vision & Trade-offs.
- Business context & Judgment.
- Security-critical decisions.
- Final responsibility.
- Superhuman execution speed.
- Encyclopedic syntax recall.
- Pattern-based generation.
- Zero real-world experience.
The Classification Framework
If a bug in the code could cause a security incident, data loss, or a production outage—it's Red.
Tasks by Color
- Boilerplate (CRUD, Forms, DTOs).
- Writing JSDoc / Documentation.
- Generating Unit Tests.
- Formatting & Linting fixes.
- System / Database Architecture.
- Auth & Security logic.
- Core business rules.
- Debugging complex race conditions.
Case Study: Product Search Feature
Most real-world features contain both colors. The skill is in the decomposition.
- 🛑 RED: Search algorithm choice (Fuzzy vs. Semantic), Indexing strategy, Performance SLAs.
- ✅ GREEN: Implementing
fuzzySearch()helper, Generating TypeScript interfaces. - ✅ GREEN: Creating the test suite for the service, Writing OpenAPI documentation.
Preventing Skill Atrophy
Unused muscles weaken. Your problem-solving instinct is your primary career asset—don't let it dull.
Mastery Practices
Before using AI, spend 5 minutes solving it yourself. Sketch the approach and pseudocode first.
Don't ask "Write this." Ask "Review my approach and tell me what I'm missing." Get understanding, not just code.
Schedule 2–3 hours a week for "Zero AI" coding. Side projects or algorithms keep the muscle memory alive.
The 70/30 Sustainable Ratio
Boilerplate, Tests, Docs, Formatting. Use AI for the 70% of work that is repetitive and pattern-based.
Core logic, Security, Architecture. This is the highest-value 30% that determines system quality.
AI helps you move faster everywhere else so you can give the manual 30% your full, un-rushed attention.
Now that you know what to delegate, how do you do it perfectly? Next, we master the Specification Framework for production-ready code.
