# game-playtest

Plan a structured playtest, record player behavior, and make sense of the session. Use it to check whether players understand a mechanic or onboarding flow.

## What it does

The skill guides preparation around specific questions that can be answered by watching a session. It helps create an observation sheet and per-player tracking form, then outlines how to keep test conditions consistent, prepare a clean save, and record the screen with audio. That gives the team concrete observations to review after the session.

During a playtest, the facilitator watches and takes notes rather than helping the player. Keep observed actions separate from later interpretations. A player’s description of the controls can conflict with what they do; repeated incorrect button presses count as behavioral evidence. This workflow is for structured playtesting, not QA bug hunting or balance tuning.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add AlterLab-IEU/AlterLab_GameForge --skill game-playtest -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-playtest/SKILL.md

## When to use it
- write observable questions for a playtest
- prepare a player observation sheet
- compare player actions with their comments
- review feedback on a new game feature

## Example prompts
- Plan a playtest for the new mechanic and draft questions that observers can answer from player behavior.
- Create an observation sheet and a tracking form for each player.
- Analyze the session notes, separating observed actions from interpretations.

# AlterLab GameForge -- Structured Playtest Analysis

Playtesting is not asking players if they had fun. It is the disciplined observation of player behavior to identify where the design succeeds and where it fails. The player's mouth lies -- their hands do not. Nintendo has known this for decades: Miyamoto famously watches players silently, trusting their confusion over their compliments. Larian ran thousands of community playtests during BG3's Early Access, and every major system change traced back to behavioral data, not forum polls. This workflow provides a rigorous behavioral observation framework that transforms raw playtest sessions into actionable design insights.

### Purpose & Triggers

**Invoke this workflow when:**
- A build is ready for external eyes and you need structured feedback, not just reactions
- Specific design questions need answering: "Do players understand the crafting system?" not "Is the game good?"
- Onboarding flow needs validation -- can new players learn the core mechanic without a tutorial?
- Difficulty curve assessment -- are players in the flow channel or oscillating between boredom and frustration?
- A new feature has been integrated and its impact on the overall experience is unknown
- Pre-release polish pass needs data on which rough edges matter most to players
- Competitive analysis requires side-by-side comparison with a reference game

**Do NOT use this workflow when:**
- You need to test a raw mechanic in isolation (use `game-prototype` instead)
- The build is so broken that testers will spend most of their time hitting bugs (fix critical bugs first, then playtest)
- You want marketing quotes or positive testimonials (that is PR, not playtesting)

### Critical Rules

1. **Define questions before inviting testers.** Every playtest answers specific questions. "Is it fun?" is not a question -- it is a prayer. "Can players complete the first dungeon without dying more than twice?" is a question. Celeste's playtests asked "can players learn the dash mechanic within the first three screens?" -- specific, observable, actionable.
2. **The facilitator does not play.** You observe. You take notes. You do not help, explain, suggest, or react. Your poker face is a scientific instrument.
