# SubagentDispatcher SDK Implementation

**Completed:** 2026-03-21
**Commit:** `03db04e` - feat: replace simulateSubagent with actual SDK calls

## What Was Built

Replaced the placeholder `simulateSubagent()` with actual Letta Code SDK calls.

### Key Features

#### 1. Dynamic SDK Import
```typescript
let sdk: typeof import('@letta-ai/letta-code-sdk') | null = null;

async function getSDK(): Promise<typeof import('@letta-ai/letta-code-sdk')> {
  if (!sdk) {
    sdk = await import('@letta-ai/letta-code-sdk');
  }
  return sdk;
}
```

#### 2. Model Tier Mapping
```typescript
const MODEL_TIERS = {
  opus: 'kimi-k2.5',      // Complex reasoning, architecture
  sonnet: 'nemotron-3-super', // Implementation, coding
  k2: 'k2-thinking',      // Verification, edge cases
};
```

**Selection logic:**
- `architecture` / `design` → opus (kimi-k2.5)
- `static` / `style` → sonnet (nemotron-3-super)
- `runtime` / `security` → k2 (k2-thinking)

#### 3. spawnSubagent() Method
Uses actual SDK primitives:
- `SDK.createAgent()` - Spawns subagent with persona + model
- `SDK.prompt()` - One-shot execution with recovery
- `AbortController` - Cancellation support

#### 4. Iterative Refinement
```typescript
async refineUntilConvergence(task, options): Promise<SubagentResult>
```

**Features:**
- Configurable max iterations (default: 3)
- Convergence detection based on result stability
- Task refinement between iterations
- Returns best result from all attempts

### File Location
`/home/ani/Projects/community-ade/community-ade-wt/mvp-unified/src/verification/executors/SubagentDispatcher.ts`

### Next Steps
- Connect to Express routes for HTTP-triggered verification
- Add result caching layer
- Implement result streaming for long-running verifications
- Add metrics collection (duration, success rates by model tier)
