Rubber Duck in GitHub Copilot CLI now supports more models

Short summary

GitHub Copilot CLI's Rubber Duck code review agent now supports cross-model critic selection in development sessions. Developers using GPT-based environments can leverage Claude-powered code critics, and Claude sessions can use GPT reviewers, decoupling the session model from the critic model. This multi-model flexibility expands workflow compatibility for development teams.
