# agent-container-pack (acpack)

CLI tool that generates CLAUDE.md/AGENTS.md and MCP configurations from a single `agentpack.yml` manifest.

## Why acpack?

Claude Code and Codex CLI have different configuration formats. acpack uses a single YAML manifest (`agentpack.yml`) as the source of truth, generating the appropriate files for each tool:

- `CLAUDE.md` / `AGENTS.md` - Project instructions
- `.claude/settings.json` - Claude Code MCP configuration
- `codex.config.toml` - Codex CLI MCP configuration

## Installation

```bash
# With uvx (no install required)
uvx --from acpack acpack --help

# Or install globally (recommended)
uv tool install acpack
acpack --help

# Or with pip
pip install acpack
```

## Usage

### New Project

```bash
# 1. Initialize project (creates .devcontainer/ and agentpack.yml)
cd my-project
acpack init

# 2. Edit agentpack.yml (project name, MCP servers, etc.)
vim agentpack.yml

# 3. Generate configuration files
acpack generate --write
```

### Existing Project

```bash
# 1. Create agentpack.yml manually or via init
acpack init

# 2. Edit agentpack.yml to match your project
vim agentpack.yml

# 3. Generate
acpack generate --write
```

### Team Workflow

```bash
# Team members clone the repo and run:
git clone <repo>
cd <repo>
acpack generate --write
# → Ready to use Claude Code / Codex CLI
```

### Workflow Diagram

```
acpack init          # Run once
       ↓
agentpack.yml           # Edit this file (single source of truth)
       ↓
acpack generate      # Run after each yml change
       ↓
CLAUDE.md, AGENTS.md    # Auto-generated (don't edit manually)
.claude/settings.json
codex.config.toml
```

## Manifest Format

Create an `agentpack.yml` in your project root:

```yaml
version: "1"

project:
  name: "my-project"
  description: "Project description"

stack: python

stacks:
  python:
    detect:
      any: ["pyproject.toml", "requirements.txt"]
    deps: "uv sync"
    lint: "uv run ruff check ."
    typecheck: "uv run ty check"
    test: "uv run pytest"
    run: "uv run python main.py"

mcp:
  servers:
    Ref:
      transport: http
      url: "https://api.ref.tools/mcp"
      env:
        X_REF_API_KEY: "${env:X_REF_API_KEY}"

workflows:
  - name: "Development Flow"
    steps:
      - "uv run ruff format . && uv run ruff check ."
      - "uv run pytest"

pre_commit: ["prettier", "ruff", "ty"]

safety:
  preset: default
```

## Generated Files

| File | Purpose |
|------|---------|
| `CLAUDE.md` | Claude Code project instructions |
| `AGENTS.md` | Codex CLI project instructions (same content) |
