Cairn

Know which coding-agent workspace needs you now, and recover what happened while you were away.

Representative Cairn workspace and session handoff.

The terminal stays central. The missing context stays close.

Cairn reduces the tab hunt without putting another orchestration system between you and your tools.

See what needs you

Running, waiting, needs-you, done, and dormant states keep local and SSH workspaces in one scannable list beside the terminal you are using.

Recover the handoff

Managed sessions retain the request, final response, observed files, and agent-reported validation. Duration, turns, tools, and tokens appear when available.

Inspect captured work

Open a saved transcript or a file-level Git diff when Cairn captured one. Then return directly to the workspace and continue in the terminal.

Built for the way coding agents actually run.
