TL;DR
- Pass task summaries directly between separate terminal instances without manual copy-pasting
- Maintain clean context windows by transferring targeted task states instead of full chat histories
- Coordinate parallel frontend and backend agent workflows across separate terminal tabs
Cross-Session Coordination
Anthropic added inter-session messaging to Claude Code, allowing separate instances running in different terminal tabs to pass messages to one another. Instead of pausing work to draft a handoff summary, you can instruct Claude directly: tell it to update the session in your other tab about API changes or completed database migrations.
Context Window Preservation
The feature sends only targeted task summaries rather than raw conversation logs or heavy file structures. This ensures the receiving session maintains a clean context window while picking up work mid-task.
When to use
- Managing separate frontend and backend tasks in split terminal tabs
- Running long background refactoring in one window while continuing interactive feature development in another
When NOT to use
- Single-file quick edits where running a single session is sufficient
- Stateless background scripts that do not depend on ongoing conversation context
What to do today
- Update Claude Code CLI to the latest version
- Try delegating background refactoring tasks in a second terminal session while working in the primary prompt

I've been wanting this for a while. I've developed my own routine for doing this and can't wait to stop doing it!
