# game-design-review

This skill reviews a game design document for conflicting sections, mechanics detached from the game’s pillars, and gaps that could hinder implementation.

## What it does

The skill reads the full document before reviewing it. It checks for required GDD sections, traces mechanics back to design pillars, and compares the stated target aesthetics with the mechanics meant to support them. Findings receive explicit severity ratings.

Feedback should identify the problem and its section, then suggest a direction rather than dictate a fix. The workflow refers to `docs/game-design-theory.md` for design principles. It reviews an existing document; brainstorming and balance tuning belong to separate skills.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add AlterLab-IEU/AlterLab_GameForge --skill game-design-review -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/game-design-review/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/game-design-review/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add AlterLab-IEU/AlterLab_GameForge --skill game-design-review -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/game-design-review/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add AlterLab-IEU/AlterLab_GameForge --skill game-design-review -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/game-design-review/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install AlterLab-IEU/AlterLab_GameForge game-design-review
```

2. **Manually: put the files in place**
- File: `.github/skills/game-design-review/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add AlterLab-IEU/AlterLab_GameForge --skill game-design-review -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/AlterLab-IEU/AlterLab_GameForge --path skills/workflows/game-design-review
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/game-design-review/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add AlterLab-IEU/AlterLab_GameForge --skill game-design-review -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/AlterLab-IEU/AlterLab_GameForge/tree/HEAD/skills/workflows/game-design-review/SKILL.md

## When to use it
- Find mechanics that do not support any design pillar
- Spot a mismatch between target aesthetics and gameplay systems
- Catch contradictions across GDD sections
- Flag gaps that could confuse implementation
- Rank findings by severity

## Example prompts
- Review my GDD and point out contradictions between sections.
- Check which mechanics lack a link to the design pillars in `docs/my-game.md`.
- Assess whether this design document gives enough direction to begin implementation.

# AlterLab GameForge -- Design Document Review Workflow

A game design document is a living contract between your ambitions and your execution capacity. A bad GDD is not poorly formatted -- it is one that lets the team build confidently in the wrong direction for weeks before anyone notices. Hollow Knight's design doc worked because Team Cherry kept it tight, falsifiable, and obsessively focused on three pillars. Most GDDs fail because they describe a game without constraining it -- anything goes, so nothing works.

This is not a checklist review. A checklist confirms sections exist. This review confirms sections are good -- internally consistent, psychologically grounded, scope-honest, and specific enough to guide implementation decisions. Disco Elysium's systems-narrative integration did not happen by accident -- it happened because the design document specified exactly how every skill check connected to every dialogue branch. That level of specificity is what this review demands.

### Purpose & Triggers

Use this workflow when:
- A designer says "review my GDD" or "give feedback on my design document"
- Before starting implementation, to catch problems while they are cheap to fix
- After significant design changes, to re-validate internal consistency
- When a playtest reveals problems and you suspect the root cause is in the design
- When team members disagree about what the game is supposed to be

Problems this solves:
- Mechanics that do not serve any design pillar (orphan features)
- Target aesthetics that contradict the actual mechanics (MDA misalignment)
- Scope estimates that ignore reality (optimism masquerading as planning)
- Design documents that describe a game but do not constrain it (anything goes = nothing works)
- Systems that interact in unintended ways (emergent conflict)
- Missing sections that will cause confusion during implementation

### Critical Rules

1. **Read the whole document before commenting.** Context matters. A mechanic that seems
   orphaned in Section 3 might be justified by the progression system in Section 7. Read
   everything first, then analyze.

2. **Severity matters.** Not all findings are equal. A missing core loop definition is
   Critical. A vague art style reference is Minor. Assign severity explicitly so the
   designer knows where to spend time.
