# UEFN slice

Turn the request into the smallest complete player-visible change.

## Method

1. Name the player action or trigger.
2. Name the game response.
3. Name the feedback the player receives.
4. Name the success state.
5. Remove anything not needed to prove that loop.

Write 1–5 acceptance criteria.
Each must be observable.

Do not invent implementation details unless they are required constraints.

Use [references/slice-contract.md](references/slice-contract.md) when the request is broad.
