## Detailed Analysis

### 1. CRITICAL: Debug Agent (Built-in)

**Current State:**
```yaml
debug:
  model: ollama-cloud/gpt-oss:20b
  status: BROKEN
  IF: ~65 (underwhelming)
```

**Recommendation:**
```yaml
debug:
  model: ollama-cloud/gemma4:31b
  provider: ollama
  IF: 83
  context: 256K
  features: thinking mode, vision
  license: Apache 2.0
```

**Rationale:**
- gpt-oss:20b is BROKEN on Ollama Cloud
- Gemma 4 31B has IF:83 vs gpt-oss IF:65 = **+29% improvement**
- 256K context (vs 8K) = 32x more context
- Thinking mode enables better debugging
- Alternative: Nemotron-Cascade-2 (IF:82.9, LiveCodeBench 87.2)

**Action: Apply immediately**

---

### 2. CRITICAL: Release Manager

**Current State:**
```yaml
release-manager:
  model: ollama-cloud/devstral-2:123b
  status: BROKEN
  IF: ~75
```

**Recommendation:**
```yaml
release-manager:
  model: openrouter/qwen/qwen3.6-plus:free
  provider: openrouter
  IF: 90
  score: 76★
  context: 1M
  cost: FREE
```

**Rationale:**
- devstral-2:123b NOT WORKING on Ollama Cloud
- Comparison matrix shows Qwen 3.6+ = 76, GLM-5 = 76 (tie)
- BUT Qwen has IF:90 vs GLM-5 IF:80 = better for git operations
- 1M context for complex changelogs
- FREE via OpenRouter
- Fallback: nemotron-3-super (IF:85, 1M context) for heavy tasks

**Action: Apply immediately**

---

### 3. HIGH: Orchestrator

**Current State:**
```yaml
orchestrator:
  model: ollama-cloud/glm-5
  IF: 80
  score: 82
  context: 128K
```

**Recommendation:**
```yaml
orchestrator:
  model: openrouter/qwen/qwen3.6-plus:free
  provider: openrouter
  IF: 90
  score: 84★
  context: 1M
  cost: FREE
```

**Rationale:**
- Orchestrator is CRITICAL agent - needs best possible IF for routing
- IF:90 vs IF:80 = **+12.5% improvement in instruction following**
- 1M context for complex workflow state management
- Score: 84 vs 82 = +2% overall
- +3x speed improvement
- FREE via OpenRouter

**Action: Apply after critical fixes**

---

### 4. HIGH: Pipeline Judge

**Current State:**
```yaml
pipeline-judge:
  model: ollama-cloud/nemotron-3-super
  IF: 85
  score: 78
  context: 1M
```

**Recommendation:**
```yaml
pipeline-judge:
  model: openrouter/qwen/qwen3.6-plus:free
  provider: openrouter
  IF: 90
  score: 80★
  context: 1M
  cost: FREE
```

**Rationale:**
- Judge needs IF:90 for accurate fitness scoring
- Score: 80 vs 78 = +3% improvement
- Same 1M context as Nemotron
- FREE via OpenRouter
- Keep Nemotron as fallback for heavy parsing tasks

**Action: Apply after critical fixes**

---

### 5. MEDIUM: Evaluator (Burst Mode)

**Current State:**
```yaml
evaluator:
  model: openrouter/qwen/qwen3.6-plus:free
  IF: 90
  score: 81
```

**Recommendation: TWO-TIER APPROACH**

```yaml
# Primary: Qwen 3.6+ (for detailed scoring)
evaluator:
  model: openrouter/qwen/qwen3.6-plus:free
  IF: 90
  score: 81
  use: detailed_scoring

# Burst: Groq gpt-oss:120b (for fast numeric scoring)
evaluator-burst:
  model: groq/gpt-oss-120b
  speed: 500 t/s
  IF: 72
  use: quick_numeric_scoring
  limit: 50-100 calls/day
```

**Rationale:**
- Qwen 3.6+ score: 81 is already optimal
- Groq gpt-oss:120b: 500 tokens/sec = +6x speed for quick scoring
- IF:72 is sufficient for numeric evaluation
- Use burst for simple: "Score: 8/10" responses
- Use Qwen for complex: full report with recommendations

**Action: Optional enhancement**

### 6. LOW: Keep Current Models

These agents are ALREADY OPTIMAL:

| Agent | Current Model | Score | Reason to Keep |
|-------|---------------|-------|----------------|
| `requirement-refiner` | glm-5 | 80★ | Best score for system analysis |
| `security-auditor` | nemotron-3-super | 76 | Best for 1M ctx security scans |
| `markdown-validator` | nemotron-3-nano | 70★ | Lightweight validation |
| `code-skeptic` | minimax-m2.5 | 85★ | Absolute LEADER in code review |
| `the-fixer` | minimax-m2.5 | 88★ | Absolute LEADER in bug fixing |
| `lead-developer` | qwen3-coder:480b | 92 | SWE-bench 66.5%, best coding model |
| `frontend-developer` | qwen3-coder:480b | 90 | Excellent for UI |
| `backend-developer` | qwen3-coder:480b | 91 | Excellent for API |

**Action: No changes needed**
