# src/agents/ — 13 Agent Definitions

**Generated:** 2026-02-21

## OVERVIEW

Agent factories following `createXXXAgent(model) → AgentConfig` pattern. Each has static `mode` property. Built via `buildAgent()` compositing factory + categories + skills.

## FACTORY PATTERN

```typescript
const createXXXAgent: AgentFactory = (model: string) => ({
  instructions: "...",
  model,
  temperature: 0.1,
  // ...config
})
createXXXAgent.mode = "subagent" // or "primary" or "all"
```

Model resolution: `AGENT_MODEL_REQUIREMENTS` in `shared/model-requirements.ts` defines fallback chains per agent.

## MODES

- **primary**: Respects UI-selected model, uses fallback chain
- **subagent**: Uses own fallback chain, ignores UI selection
- **all**: Available in both contexts (Sisyphus-Junior)
