## What it does

The skill handles the initial Archcore setup in a repository. It wires host MCP settings and hooks, adding managed blocks to `CLAUDE.md` or `AGENTS.md`. Using facts extracted from the existing codebase, it builds the `.archcore/` directory with stack rules, data models, and hotspot module specifications.

Modes are controlled by the first argument: `import` or `refresh`. The `import` mode extracts developer context from `CLAUDE.md`, `.cursor/rules`, and ADR folders into native typed documents. The `refresh` mode updates a seeded repository when new schemas or configs appear, or when targeting a specific domain.

Nothing is written before `confirm`. The skill outputs a single preview first, where you can inspect planned files and select analysis depth (`light`, `standard`, `deep`).

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add archcore-ai/archcore --skill init -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add archcore-ai/archcore --skill init -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add archcore-ai/archcore --skill init -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install archcore-ai/archcore init
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add archcore-ai/archcore --skill init -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/archcore-ai/archcore --path plugins/archcore/skills/init
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add archcore-ai/archcore --skill init -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/archcore-ai/archcore/tree/HEAD/plugins/archcore/skills/init/SKILL.md

## When to use it
- Wire MCP configs and host hooks for agent alignment
- Convert existing `CLAUDE.md`, `.cursor/rules`, and ADR folders into typed architecture documents
- Seed an initial architecture index, run guide, and module specs
- Refresh repository context after adding new schemas or configurations

## Example prompts
- /archcore:init
- /archcore:init import
- /archcore:init refresh

name: init
argument-hint: "[import|refresh] [path or domain]"
description: "First-time Archcore setup. Wires the host (MCP config, hooks, CLAUDE.md/AGENTS.md managed block), measures the authored context the repo already holds, then composes a first-day seed — stack rule, run guide, data-model, integrations, config, entry points, public surface, a linked architecture overview, and specs for the top hotspot modules — shown in ONE preview and created on a single confirm. Modes, named as the first word: init import converts the repo's authored context — CLAUDE.md, AGENTS.md, .cursor/rules and other agent instructions, ADR and RFC folders, contributor docs, internal pages of a published docs site, recoverable git history — into native typed documents with no import marks, staged by a plan when the volume is large; init refresh adds facts that appeared since, or drills into one domain with init refresh <domain>. Use on a fresh clone, empty `.archcore/`, 'set up archcore', 'migrate our CLAUDE.md to archcore', 'import our docs and ADRs', or to wire host configs. Not for individual docs or planning."

# /archcore:init

First-time onboarding. Wires the host, measures the authored context the repository already holds, and fills `.archcore/` from two sources — what people wrote and what the code shows — so the code-alignment hook and per-command grounding have substance from day one. Per `magic-first-day-init.adr` and `init-import-mode.adr`: extractive facts are composed in full; authored content wins over synthesized content on the same subject; the overview is an index, never a prose blob. **Nothing is written before `confirm`.**

Before planning or writing relations, load `skills/_shared/relation-authoring.md`.
Apply its claim check to seed and import wiring after reading the endpoint content.

## Arguments

The first word selects the run: `import` or `refresh`. These two words are the command's modes in the sense of `command-surface-v2.spec`. The rest of the arguments is the subject. No arguments, or any other first word, start a plain init.

- `import [path]` — convert the repository's authored context into native documents, at all five discovery levels of `lib/sources.md`; a path limits the run to that path. Resumes an open import plan when one exists.
- `refresh [path or domain]` — re-run on a seeded repo to add facts that appeared since (a new schema, config, or modules) and to retrofit host wiring. A subject scopes the top-up: an existing path wins; otherwise a detected domain slug runs the single-domain pass. Bypasses the "already seeded" early-exit.
- Depth and scale are not arguments. The preview offers the toggles `depth:light|standard|deep` (default `standard`) and `scale:small|medium|large`, where the user already sees each choice's cost (`lib/seed-compose.md`). Import has no depth.

## When to use

- Empty `.archcore/` — the SessionStart nudge points here.
- First session on a fresh clone / fresh install.
- User says: "initialize archcore", "set up archcore", "seed archcore", "first-time setup", "what should I do first".
```
