    I usually have 3-4 Claude Code sessions running (different repos, one reviewing, one testing) and moving context between them was me and my clipboard all day.
    
    So I built claude-inter-comm. You literally just say "send the reviewer session a summary of this fix and ask it to run the tests" — the other session gets it, does the work, and replies. The GIF is the real flow.
    
    Install (needs Node 20+):
    
    ```
    claude plugin marketplace add lalantony/claude-inter-comm
    claude plugin install claude-inter-comm@claude-inter-comm
    ```
    
    How it works under the hood: no daemon, no ports — messages are CloudEvents JSON files in a maildir-style inbox, and Claude Code's own hooks deliver them at natural boundaries. By default the receiving session notifies you before acting on anything (no hijacking); there's an opt-in standby mode if you want a session reacting to incoming work autonomously.
    
    Honest limits: same machine only for now, Claude Code only, and a fully idle session sees mail on its next interaction rather than instantly. Native Agent Teams doesn't cover this — it only messages agents it spawned itself, which is why I built this.

    MIT, 32 tests, docs include the full architecture decision log. Would love bug reports (especially macOS/Linux) and roasts of the design.

I got tired of copy-pasting between my Claude Code sessions, so I built them a message bus claude plugin
