Make Your Claude Code Sessions Communicate With Each Other

A Best-Practices practice is to have 1 Claude Code Terminal open for planning using an expensive model and another open for coding using a less expensive model, following the plan created by the expensive model. Optionally, a 3rd Claude Code terminal for project management tasks like documentation, ticket management, etc... using an even lower IQ model like Haiku or Sonnet. Later, you may decide on some updates to the plan. YOu can just tell your expensive model terminal the updates to the plan and simply TELL IT to tell the other Claude Code coding session terminal. It will find it and communicate with it. Turns out, this is a feature in Claude Code. Chances are good that competing products have similar features. In short: - Expensive model for planning (like Fable 5) - Less expensive model, but good coding model (like Opus 5) for coding. - They can talk to each other.
