Official Dev Container Feature

What variant of Codex are you using?

CLI

What feature would you like to see?

Please provide an official Dev Container Feature so it can be installed directly from devcontainer.json.

I know there is already an unofficial feature at dirien/devcontainer-feature-codex, but relying on an unofficial package is risky. It may stop being maintained, fall behind releases, or become compromised, which would leave users stuck. An official feature maintained by openai would be more stable and trustworthy.

This is already a common pattern. Anthropic ships an official Claude Code feature at anthropics/devcontainer-features, and GitHub ships an official Copilot CLI feature at devcontainers/features

Example:

// .devcontainer/devcontainer.json
{
  "features": {
    "ghcr.io/openai/features/codex:1": {}
  }
}
