# /refine — Prompt Optimizer Transform any brief, draft, or one-liner into a production-ready structured prompt. ## When to Use - User wants to improve a prompt or brief - User references `/refine` with text or a file path - A worker needs to optimize a prompt before dispatching it ## Flow 1. **Detect mode:** argument starts with `@` -> file mode; otherwise -> text mode. 2. **Read input:** file mode reads the target file; text mode uses the raw argument. 3. **Spawn refiner subagent:** system prompt = the Prompt Optimizer System Prompt below.
