Hi HN,

  Different models and CLI tools have their own strengths, but we are often forced to choose just one, or rely on hidden "agentic" API calls that are opaque and hard to control.

  I built CCB to solve this. It lets you freely combine different CLIs (Claude Code,
  Gemini, Codex, OpenCode, Droid) and mount them into Tmux split panes with a single command.

  It solves the "single model tunnel vision" by enabling stable interaction between them. You can use natural language in one CLI (e.g., Claude) to delegate tasks to other visible CLIs and get results back.

  For example:
   * You can ask Claude to design a feature.
   * Claude can then explicitly instruct Gemini (in the adjacent pane) to read the docs or review the plan.
   * You see everything happen in real-time across the splits.


  Feedback and PRs are welcome!
