Design a single level — layout, pacing, encounters, secrets, reward gating — outputs a level design doc and a node-tree skeleton for summer_create_scene.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# /design-level — Design One Level

## Overview

A level is a controlled sequence of player experiences in physical space. Layout, pacing, encounters, secrets, and reward gating must work together — a "fun layout" with a flat pacing curve still feels boring. This skill walks the six design beats of a single level and drops a node-tree skeleton ready for `summer_create_scene`.

**Core principle:** A level has a *pacing curve* and a *teaching arc*. If you can't draw the tension graph and name what the player learned by the end, the level isn't designed yet.

## Steps

### 1. Pin the level type

Ask exactly one question:

> What kind of level? Pick one: tutorial / hub / combat encounter / boss / exploration / puzzle / stealth / platforming-challenge / mixed.

Each type has different beats. Don't blend types in v1 — a "boss room with stealth and puzzles" is three levels poorly squeezed into one.

### 2. Read context

If `.summer/GameSoul.md` exists, read it. The level must serve the brief's core loop and the three mechanics.

```
Read .summer/GameSoul.md
```

If `.summer/mechanics/` exists, list the mechanics. Quote them back:

How to install

The exact contents, by fingerprint

mdr add summerengine/summer/design-level@sha256:4bac0313b810e887

The line at the top of this page pins the label git:20261010.4ade947, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
