# Skill: expand-beat
**What it does.** Turns a one-line beat ("the girl realizes he knows") or a rough fragment into drafted prose. The lightweight sibling of `draft-scene` — for when the author has a seed but not a full scene contract.
**Triggers**
- "expand this beat: {...}"
- "/expand-beat"
- "turn this note into a scene"
- "I have this fragment, develop it"
- Equivalent phrasing in the project's output language
**Input.** The beat or fragment, plus (asked if missing): who is on stage, where it sits in the chapter, target length.
**Output.** Drafted passage in a `_draft` block or file, marked for curation. **Never written into the manuscript.**
> **Write the prose in the project's output language.**

## Core principle
> **The beat is the author's plot decision. Expansion adds texture, not events.**
The line between expanding and inventing:
- Beat: *"the merchant admits he sent the letter"* → the expansion may add hesitation, gesture, the room, the pause before the admission — **but not** a second revelation, a new character arriving, or a consequence the beat doesn't contain.
If the expansion needs a plot decision the beat doesn't carry ("does she believe him?"), **stop and ask**. One question at the boundary beats a paragraph of invented plot.

## Execution protocol
### Step 1 — Load context
Lighter than `draft-scene`, but never zero:
1. `.project/config/project.yaml` — output language
2. `.project/config/persona.md` — voice, ceilings, model passages
