Feature Request: Shared / Organisation-Level Codex Cloud Environment Templates

Problem

Codex Cloud environments are currently associated with individual repositories. For organisations with a large number of repositories, this creates significant administrative overhead.

For example, an organisation with approximately 100 repositories may need to create and maintain up to 100 separate Codex Cloud environments, even where most repositories share the same development stack and configuration.

In practice, many repositories need largely identical configuration, such as:

• Java / Gradle tooling
• Node.js / npm tooling
• .NET SDKs
• Python tooling
• Organisation CA certificates
• Standard network allowlists
• Common environment variables
• Internal package repository configuration
• Standard bootstrap/setup scripts

Duplicating this configuration for every repository increases onboarding effort, creates configuration drift, and makes centrally managing Codex Cloud at enterprise scale difficult.

Requested Capability

Introduce reusable organisation-level Codex Cloud environment templates that can be applied to multiple repositories.

For example:

AP+ Java Environment
  - Java 21
  - Gradle
  - Node.js
  - AWS CLI
  - Organisation CA certificates
  - Standard network configuration

        ↓

  repo-a
  repo-b
  repo-c
  ...

A repository-specific Codex environment would reference or inherit from the shared template rather than duplicating its configuration.

Ideally

The capability would support:

1. Reusable environment templates

   • Define an environment configuration once.
   • Associate it with any number of repositories.

2. Inheritance

   • Organisation defaults are inherited by repository environments.
   • Repository-specific configuration can extend or override the defaults where necessary.

3. Automatic environment provisioning

   • Optionally create a Codex environment automatically when a repository is first used with Codex Cloud.
   • Apply an appropriate template based on organisation defaults, repository metadata, language, topic, or other configuration.

4. Central updates

   • Updating a shared template should update the inherited configuration for all repositories using it, without having to edit each environment individually.

5. API / CLI / Terraform support

   • Allow environments, templates, and repository associations to be managed programmatically for larger organisations.

Example

An organisation with 100 repositories might only need to maintain:

Java / Spring template
Node / TypeScript template
.NET template
Python template
Generic template

Repositories could then simply be associated with one of these templates.

This would reduce the management model from approximately 100 independently configured environments to 4–5 centrally managed templates.

Business Value

This would make Codex Cloud substantially easier to adopt and operate across large engineering organisations by:

• reducing repository onboarding effort;
• preventing configuration drift;
• enabling platform teams to manage approved development environments centrally;
• simplifying security and network configuration;
• improving consistency across repositories; and
• making Codex Cloud practical for organisations with hundreds or thousands of repositories.

The current repository-level environment model works well for small numbers of repositories, but a reusable template/inheritance model would provide a much better scaling model for enterprise adoption.

Additional information

No response

No files, tests, or implementation entry points are identified in the issue. Start by locating the existing Codex Cloud environment model and its management interfaces, then clarify the template, inheritance, provisioning, update, and API/CLI/Terraform requirements before defining completion criteria.
