Usage

Add the feature to your devcontainer.json:

Claude Code — Default

{
    "name": "My Dev Container",
    "image": "mcr.microsoft.com/devcontainers/base:ubuntu",
    "features": {
        "ghcr.io/cjcrobin/devcontainer-features/claudecode:1": {}
    }
}

Claude Code — Pinned version

{
    "name": "My Dev Container",
    "image": "mcr.microsoft.com/devcontainers/base:ubuntu",
    "features": {
        "ghcr.io/cjcrobin/devcontainer-features/claudecode:1": {
            "version": "1.0.17"
        }
    }
}

Claude Code — With host config mounted

Mounts .claude/ and .claude.json from the host so credentials and settings survive container rebuilds:

{
    "name": "My Dev Container",
    "image": "mcr.microsoft.com/devcontainers/base:ubuntu",
    "features": {
        "ghcr.io/cjcrobin/devcontainer-features/claudecode:1": {
            "globalConfigHome": "/host/home/username",
            "projectConfigFolder": "/host/home/username/myproject"
        }
    }
}

Claude Code Options

Option	Description	Default
`version`	Version of `@anthropic-ai/claude-code` to install (e.g. `latest`, `1.0.17`)	`latest`
`globalConfigHome`	Host path whose `.claude/` and `.claude.json` are linked into `~/.claude/` and `~/.claude.json`	`""` (uses `~`)
`projectConfigFolder`	Host path whose `.claude/` and `.claude.json` are linked into `${workspaceFolder}`	`""` (skipped)

Codex CLI

Installs OpenAI Codex CLI via the official standalone installer. Downloads a pre-built statically-linked (musl) binary — works on all Linux distributions with no runtime dependencies.

{
    "name": "My Dev Container",
    "image": "mcr.microsoft.com/devcontainers/base:ubuntu",
    "features": {
        "ghcr.io/cjcrobin/devcontainer-features/codexcli:1": {}
    }
}

No options — no presets. Run codex after container creation to sign in or configure your environment.

Playwright CLI — Default

Installs Playwright CLI (@playwright/cli) globally via npm. Provides a token-efficient CLI interface for browser automation, designed for coding agents.

{
    "name": "My Dev Container",
    "image": "mcr.microsoft.com/devcontainers/base:ubuntu",
    "features": {
        "ghcr.io/cjcrobin/devcontainer-features/playwright-cli:1": {}
    }
}

Playwright CLI — Pinned version, skip skills

{
    "name": "My Dev Container",
    "image": "mcr.microsoft.com/devcontainers/base:ubuntu",
    "features": {
        "ghcr.io/cjcrobin/devcontainer-features/playwright-cli:1": {
            "version": "0.1.17",
            "installSkills": false
        }
    }
}

Playwright CLI Options

    "features": {
        "ghcr.io/cjcrobin/devcontainer-features/qodercli:1": {}
    }
}

    "image": "mcr.microsoft.com/devcontainers/base:ubuntu",
    "features": {
        "ghcr.io/cjcrobin/devcontainer-features/qodercli:1": {

        }
