TASK COMPLEXITY ANALYSIS
────────────────────────────────────────────────────────────────

HAIKU (Fast, Cheap) - Use for:
├── Simple file operations (read, list, navigate)
├── Scaffolding and boilerplate generation
├── Deterministic transformations (format, lint, compile)
├── Status checks and health monitoring
├── SEO metadata generation
├── Deployment commands (after code is written)
├── Documentation formatting
├── Simple search and replace
│
│   Token cost: ~$0.25/1M input, $1.25/1M output
│   Latency: Fastest
│   Use when: Task has clear, unambiguous steps

SONNET (Balanced) - Use for:
├── Feature implementation (standard complexity)
├── Bug fixes requiring analysis
├── Content writing (articles, social posts)
├── Code review and quality checks
├── Test generation
├── Refactoring with clear patterns
├── API integration work
├── Database schema design
│
│   Token cost: ~$3/1M input, $15/1M output
│   Latency: Medium
│   Use when: Task requires reasoning but not deep strategy

OPUS (Strategic, Complex) - Use for:
├── Architecture decisions (system design)
├── Multi-agent coordination (council, swarm)
├── Strategic planning (business, product)
├── Complex debugging (multi-file, subtle bugs)
├── Security audits and vulnerability analysis
├── Enterprise AI system design
├── Book writing (narrative, character development)
├── Research synthesis (multiple sources)
├── Ambiguous requirements interpretation
│
│   Token cost: ~$15/1M input, $75/1M output
│   Latency: Slowest but most capable
│   Use when: Task requires deep reasoning, creativity, or strategy

BEFORE (No routing):
  All tasks → Opus → $75/1M output tokens

AFTER (With routing):
  Simple tasks (40%) → Haiku  → $1.25/1M  = $0.50
  Medium tasks (45%) → Sonnet → $15/1M   = $6.75
  Complex tasks (15%) → Opus  → $75/1M   = $11.25
  ──────────────────────────────────────────────
  TOTAL: $18.50 vs $75 = 75% cost reduction

// Simple task - use haiku
Task({
  subagent_type: "Explore",
  model: "haiku",
  prompt: "List all files in src/"
})

// Medium task - use sonnet (default)
Task({
  subagent_type: "code-reviewer",
  model: "sonnet",
  prompt: "Review this PR for issues"
})

// Complex task - use opus
Task({
  subagent_type: "Plan",
  model: "opus",
  prompt: "Design the architecture for a multi-tenant SaaS platform"
})

haiku (attempt) → fail → sonnet (retry) → fail → opus (final)
