# Plan-feature: brainstorm — STUB

Phase 3.2 D-03 WIRED reference implementation. Returns mock decision output for workflow runtime verification.

## Stub behavior

This skill stub returns a mock result to simulate phase success transition:

```json
{
  "status": "ok",
  "output": "<stub for plan-feature-brainstorm>",
  "decision": "mock-approved"
}
```

Phase 3.3+ dogfood: replace stub with actual superpowers brainstorming + ui-ux-pro-max spawn + decision capture.
