## What it does

The skill transforms approved game design documents into `docs/architecture/architecture.md` before sprint planning begins. It maps system layers and audits architecture decision records against the target engine.

Execution runs across nine distinct phases driven by markdown files in `references/`. Depth is managed by `docs.density`, ranging from terse bullet points to thorough explanations of trade-offs. The workflow depends on local repository scripts like `yaml-helper.sh`. Without the Claude-Code-Game-Studios repo structure, the skill will fail to load its phase references.

In collaborative mode, the agent never commits decisions silently. It uses `AskUserQuestion` to present choices and save state in `production/session-state/active.md`. The master blueprint document is written once at Phase 7.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill create-architecture -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/create-architecture/SKILL.md

## When to use it
- author docs/architecture/architecture.md before writing code
- audit existing ADRs for compatibility gaps with the engine
- map system layers and assign module ownership
- define API boundaries and module data flows

## Example prompts
- /create-architecture
- /create-architecture layers --review full
- /create-architecture adr-audit

# Create Architecture

This skill produces `docs/architecture/architecture.md` — the master architecture
document that translates all approved GDDs into a concrete technical blueprint.
It sits between design and implementation, and must exist before sprint planning begins.

**Distinct from `/architecture-decision`**: ADRs record individual point decisions.
This skill creates the whole-system blueprint that gives ADRs their context.

See `.claude/docs/director-gates.md` for the full check pattern. Individual gate definitions live in `.claude/docs/director-gates/[gate-id].md` — the spawned agent reads its own gate file; do not read it in the parent session.

Every `AskUserQuestion` call follows `.claude/docs/automation-modes.md`
(collaborative asks always · guided major-only · autonomous logs and proceeds;
`automation_always_ask` categories always prompt).

**`docs.density`** — it controls per-section *depth*, where `workflow`
controls which sections exist. `modes.rigor` sets both together; set
`docs.density` explicitly to vary depth alone: `terse` (the default, via `rigor: minimal`) = layer diagrams + decision bullets,
no essays; `balanced` = diagrams + paragraph explanations of layer choices
(`rigor: standard`); `thorough` = full prose with rationale, trade-offs, and alternatives
considered per layer. Apply it to every section you author.

**`workflow`** (see `.claude/docs/workflow-modes.md`):
- `full` — full architecture: all layers, module ownership, data flow, API
  boundaries, full ADR audit.
- `standard` — simplified: system layer map + critical ADR list only.
- `minimal` — not required. Can still be run voluntarily.

**Argument modes:**
- **No argument / `full`**: Full guided walkthrough — all sections, start to finish
- **`layers`**: Focus on the system layer diagram only
- **`data-flow`**: Focus on data flow between modules only
- **`api-boundaries`**: Focus on API boundary definitions only
- **`adr-audit`**: Audit existing ADRs for engine compatibility gaps only
