agent-container-pack

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

# With uvx (no install required)
uvx --from agent-container-pack acpack --help

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

# Or with pip
pip install agent-container-pack

Usage

New Project

# 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

# 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

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

       ↓
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
