GitHub App integration
We’ve replaced GitHub authentication via personal access token with an official GitHub connection. This lets you automatically scope access to your own repositories.Unfortunately, old templates are no longer viable after this change, and should be replaced. You can configure your GitHub connection under Connections.

Streamlined Codex Auth + Bug fixes
We’ve greatly simplified and fixed a bug with Codex authentication where tokens would not refresh as templates became too old.Replicas CLI v0.2.7
  • Automatic Codex authentication - The CLI now automatically copies ~/.codex/auth.json to your workspace when you connect, eliminating manual setup
  • Auto port forwarding - Port 1455 is now tunneled automatically, so you can login from the workspace.
  • Simplified templates - Codex CLI is now installed on every workspace by default. Templates no longer require agent authentication configuration
Upgrade to v0.2.7 with: npm i -g replicas-cli@latestOther changes:
  • The beta is no longer closed! We’ve added several more abuse protection layers, allowing us to be confident in a general availability much earlier than expected.
  • Fixed build issue with the CLI where tslib was missing.
