## What it does

The skill acts as the entry point after cloning the studio template. It inspects the project by calling `bash .claude/scripts/project-state.sh`, looking for an engine, source code, concept briefs, and architecture decision records. Next, it asks whether you are starting from zero, a vague theme, a clear concept, or existing code.

Based on your input, it determines the stage and rigor levels. It updates `project.stage` and `modes.rigor` in `project.yaml` through helper scripts. These values are saved only after explicit user confirmation. It does not touch knobs like `modes.review_mode` to prevent overriding custom configuration layers.

The skill names the immediate next action, such as `/brainstorm open` or `/setup-engine`, but never runs that step on its own. For the helper checks to work, the repository must contain the required shell scripts under `.claude/scripts/`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill start -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill start -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill start -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Donchitos/Claude-Code-Game-Studios start
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill start -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Donchitos/Claude-Code-Game-Studios --path .claude/skills/start
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill start -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/Donchitos/Claude-Code-Game-Studios/tree/HEAD/.claude/skills/start/SKILL.md

## When to use it
- detect the current game development stage from repository files
- configure documentation rigor and automation modes in project.yaml
- route a new idea or existing prototype to the right starting command
- identify whether a cloned repository still points to the template remote

## Example prompts
- /start
- I just cloned this game studio, where do I begin?
- Guide me through onboarding for a new game project

# Guided Onboarding

The entry point for a new user. It assumes no game idea, no engine and no experience: it reads
the project, asks where the user is starting from, shows what it assumes about the project, and
names the one next step. It never runs that step itself.

It writes these settings to `project.yaml`, all through helpers, and only after an explicit yes:
`project.stage` (with its legacy mirror `production/stage.txt`), `modes.rigor` and
`modes.automation`. It never writes `modes.review_mode` or `production/review-mode.txt`, and none
of the other knobs rigor fronts (`modes.workflow`, `docs.density`, `qa.level`,
`modes.story_granularity`, `team.size`): a written value pins that knob over the rigor expansion,
and a mirror file outranks it.

Ask with the question tool. Without one, list the options numbered and end your turn to wait. The
question is the last thing in the reply: no path, note or advice after it. A skipped or dismissed
question is not an answer: ask again in plain text.

The questions in Phases 2, 4 and 5 shape the project, so they are asked in every automation mode.
The engine is not one of them: `/setup-engine` chooses it. Phase 6's last question follows a
`modes.automation` already in `project.yaml`, per `.claude/docs/automation-modes.md`; with none
set, ask it.

## Phase 1: Read the project

Run `bash .claude/scripts/project-state.sh` and keep its rows. Do not show them yet; they check
the user's answer in Phase 2.

| Row | Use |
|---|---|
| `engine`, `code_root`, `source_files` | Is an engine set, and how much code is there. `source_files` of `unknown` means the code root could not be found: say that, never "no code" |
| `concept` | `design/gdd/game-concept.md` or `design/game-brief.md` exists |
| `gdd_files`, `adr` | Design documents and architecture decisions on disk (they set the stage in Phase 4) |
| `prototype`, `sprint`, `milestone`, `story` | Other existing work |
| `origin_url` | Contains `donchitos/claude-code-game-studios`, matched case-insensitively: the clone still points at the template repo, so a push or pull request would go there. A fork under another owner is the user's own |
| `stage` | The stage already recorded, if any |

Ignore `phase_inferred`: it guesses from file counts, and a project with code but no design
documents is not in Production. If the helper fails, say so and read the same facts by hand
```
