# adopt

Checks whether your GDDs, ADRs and stories match the template's format, then writes a numbered migration plan. Useful when the template's skills fail on a project that already has docs.

## What it does

\`adopt` is a brownfield skill. It does not ask what exists — it asks whether what exists will work with the template's skill pipeline. A project can have GDDs, ADRs and stories, and every format-sensitive skill will still fail silently or return wrong results if those files use the wrong internal format.

It runs in seven phases: detect project state, audit formats, classify and prioritise gaps, build the migration plan, present a summary, write the file, offer a first action. Output lands in `docs/adoption-plan-[date].md` as a persistent, checkable plan. The argument scopes the audit: blank or `full` covers all artifact types, `gdds`, `adrs` and `stories` narrow it to one format, `infra` looks at infrastructure gaps such as registry, manifest, sprint-status and stage.txt.

Automation mode resolves from `project.local.yaml`, then `project.yaml`, defaulting to `collaborative` — the skill asks before writing the plan file. It never regenerates artifacts that already have content, so do not expect it to rewrite your existing GDDs or stories.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- find out why template skills misread existing project docs
- check GDD, ADR and story formats before wiring up the pipeline
- get a numbered migration plan instead of a vague to-do list
- spot gaps in registry, manifest, sprint-status and stage.txt
- tell missing artifacts apart from ones in the wrong format

## Example prompts
- /adopt
- /adopt gdds
- /adopt infra

Resolved above — use as-is. `/adopt` also inspects `project.yaml` and the legacy
config files directly when reporting and writing migration state; that raw
inspection is deliberate and separate from the resolved values above.

# Adopt — Brownfield Template Adoption

This skill audits an existing project's artifacts for **format compliance** with
the template's skill pipeline, then produces a prioritised migration plan.

**This is not `/project-stage-detect`.**
`/project-stage-detect` answers: *what exists?*
`/adopt` answers: *will what exists actually work with the template's skills?*

A project can have GDDs, ADRs, and stories — and every format-sensitive skill
will still fail silently or produce wrong results if those artifacts are in the
wrong internal format.

**Output:** `docs/adoption-plan-[date].md` — a persistent, checkable migration plan.

**Argument modes:**

**Audit mode:** `$ARGUMENTS` (blank = `full`)

- **No argument / `full`**: Complete audit — all artifact types
- **`gdds`**: GDD format compliance only
- **`adrs`**: ADR format compliance only
- **`stories`**: Story format compliance only
- **`infra`**: Infrastructure artifact gaps only (registry, manifest, sprint-status, stage.txt)

---

**Automation mode**: Resolve `modes.automation` (`project.local.yaml` →
`project.yaml` → default `collaborative`). 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).

**`workflow`** (per `.claude/docs/workflow-modes.md`). It scopes the Phase 2 audit and
Phase 3 severity: `full` audits all doc types at full structure; `standard` audits
only the required docs/sections (optional sections are informational, not gaps);
`minimal` is a `design/game-brief.md` format check — GDDs/ADRs/UX are not expected. See Phase 2.

## Phase 1: Detect Project State
