## Methodology Selection

Based on research, selecting approaches for article coverage.

### Tier 1: MUST Include (High Authority + Reader Interest)

| Term | Why Include | Source Authority | Status |
|------|-------------|------------------|--------|
| **Vibe Coding** | Hook — Collins Word of Year 2025, everyone knows it | Wikipedia, Collins, Karpathy | ✅ verified |
| **Spec-Driven Development** | Direct contrast to vibe coding, GitHub Spec Kit | GitHub, ThoughtWorks, Martin Fowler | ✅ verified |
| **Agentic Coding** | Hot topic, Claude Code users care about this | arXiv surveys (Aug 2025, Dec 2025) | ✅ verified |
| **Ralph Loop** | HOT Jan 2026, max autonomy extreme | VentureBeat, Geoffrey Huntley, Anthropic plugin | ✅ verified |

### Tier 2: SHOULD Include (Good Authority, Practical)

| Term | Why Include | Source Authority | Status |
|------|-------------|------------------|--------|
| **AI Pair Programming** | Relatable, Copilot users know this | GitHub official, Microsoft | ✅ verified |
| **Human-in-the-Loop (HITL)** | Important concept, enterprise backing | Atlassian HULA, Google Cloud | ✅ verified |
| **TDD + AI** | Quality angle, contrasts vibe coding | Qodo.ai, Builder.io, GitHub Blog | ✅ verified |

### Tier 3: MENTION Briefly (Context/Completeness)

| Term | Why | Status |
|------|-----|--------|
| AI-DLC (AWS) | Enterprise angle, shows maturity | ⏳ verify if needed |
| Architecture-First | 2026 trend prediction | ⏳ verify if needed |
| Prompt-Driven Development | Clarify difference from vibe coding | ⏳ verify if needed |

### Tier 4: SKIP (Generic/Low Value for This Article)

- AI-Assisted Coding — umbrella term, too generic
- AI-Augmented Development — same, no distinct methodology
- Copilot-Driven Development — subset of AI Pair Programming
- Conversational Coding — too vague
- Ensemble Programming — too niche
- Deterministic AI Development — enterprise-specific, niche

---

## Article Angle

**Narrative arc:**
1. Vibe coding = entry point (hot topic, word of year)
2. Problem: works for prototypes, fails for production
3. Survey: what professionals actually use
4. Each methodology = one section with:
   - What it is (1-2 sentences)
   - When to use
   - Henry's take (from interview)
5. Conclusion: spectrum from vibe → spec-driven, choose based on stakes

## Interview Questions

Questions for Oleg to capture Henry's authentic voice:

### Vibe Coding
- Ты когда-нибудь работал в режиме vibe coding? Что получилось?
- Когда это уместно, когда нет?

### Spec-Driven Development  
- Пробовал GitHub Spec Kit или писать spec перед кодом?
- Твоё мнение — это будущее или overkill?

### Agentic Coding
- Как используешь Claude Code? Даёшь автономию или контролируешь каждый шаг?
- Что доверяешь агенту, что нет?

### AI Pair Programming
- Copilot/Cursor — как pair programmer или просто autocomplete?
- Реально ли это "парное программирование"?

### Human-in-the-Loop
- Как часто AI делает что-то без твоего одобрения?
- Где граница доверия?

### TDD + AI
- Пишешь тесты первыми при работе с AI?
- Работает ли классический TDD с генеративным AI?
