# Team Brainstorm — CSV Schema

## Master CSV: tasks.csv

### Column Definitions

#### Input Columns (Set by Decomposer)

| Column | Type | Required | Description | Example |
|--------|------|----------|-------------|---------|
| `id` | string | Yes | Unique task identifier | `"IDEA-001"` |
| `title` | string | Yes | Short task title | `"Multi-angle idea generation"` |
| `description` | string | Yes | Detailed task description (self-contained) | `"Generate 3+ ideas per angle..."` |
| `role` | string | Yes | Worker role: ideator, challenger, synthesizer, evaluator | `"ideator"` |
| `angle` | string | No | Brainstorming angle(s) for ideator tasks (semicolon-separated) | `"Technical;Product;Innovation"` |
| `gc_round` | integer | Yes | Generator-Critic round number (0 = initial, 1+ = revision) | `"0"` |

| `prev_context` | string | Aggregated findings from context_from tasks (per-wave CSV only) | `"[Task IDEA-001] Generated 8 ideas..."` |

#### Output Columns (Set by Agent)

| Column | Type | Description | Example |
|--------|------|-------------|---------|
| `status` | enum | `pending` → `completed` / `failed` / `skipped` | `"completed"` |
| `findings` | string | Key discoveries (max 500 chars) | `"Generated 8 ideas across 3 angles..."` |

### exec_mode Values

| Value | Mechanism | Description |
|-------|-----------|-------------|
| `csv-wave` | `spawn_agents_on_csv` | One-shot batch execution within wave |
| `interactive` | `spawn_agent`/`wait`/`send_input`/`close_agent` | Multi-round individual execution |

Interactive tasks appear in master CSV for dependency tracking but are NOT included in wave-{N}.csv files.

## Output Schema (JSON)

Agent output via `report_agent_job_result` (csv-wave tasks):

```json
{
  "id": "IDEA-001",
  "status": "completed",
  "findings": "Generated 8 ideas across Technical, Product, Innovation angles. Key themes: API gateway pattern, event-driven architecture, developer experience tools.",
  "gc_signal": "",
  "severity_summary": "",
  "error": ""
}
```

Challenger-specific output:

```json
{
  "id": "CHALLENGE-001",
  "status": "completed",
  "findings": "Challenged 8 ideas. 2 HIGH severity (require revision), 3 MEDIUM, 3 LOW.",
  "gc_signal": "REVISION_NEEDED",
  "severity_summary": "CRITICAL:0 HIGH:2 MEDIUM:3 LOW:3",
  "error": ""
}
```

Interactive tasks output via structured text or JSON written to `interactive/{id}-result.json`.

> Both csv-wave and interactive agents read/write the same discoveries.ndjson file.

## Cross-Mechanism Context Flow

| Source | Target | Mechanism |
|--------|--------|-----------|
| CSV task findings | Interactive task | Injected via spawn message or send_input |
| Interactive task result | CSV task prev_context | Read from interactive/{id}-result.json |
| Any agent discovery | Any agent | Shared via discoveries.ndjson |

| context_from valid | All context IDs exist and in earlier waves | "Invalid context_from: {id}" |
| exec_mode valid | Value is `csv-wave` or `interactive` | "Invalid exec_mode: {value}" |
| Description non-empty | Every task has description | "Empty description for task: {id}" |
| Status enum | status in {pending, completed, failed, skipped} | "Invalid status: {status}" |
| Valid role | role in {ideator, challenger, synthesizer, evaluator, gc-controller} | "Invalid role: {role}" |
