The Icebox
Eleven cards on one board is a board you stop reading. The Icebox parks the agent sessions you are not working with right now and keeps their conversations.
What it does
Section titled “What it does”Move to Icebox on a card takes it off the board. The session keeps running on the host — this is parking, not stopping.
Move to Board brings it back, and it returns to the position it had before, not to the end of the queue. Offsite remembers each iceboxed card’s previous board slot.
The Icebox itself lives in the sidebar and lists everything parked in the current workspace.
When to use it
Section titled “When to use it”- A long unattended run you do not want to watch — park it, let notifications tell you when it needs you.
- A session you will come back to tomorrow.
- Reclaiming board space without the decision of “do I still need this?”.
If you are done with a session, end it instead. The Icebox is not a graveyard; a parked agent still holds its context, its resume state and, if it is mid-turn, its work.
What can be parked
Section titled “What can be parked”Agent sessions that are on the board and belong to you: Claude, Codex and Grok cards, with their conversation. Bring a card back from the tab bar first, and the Icebox takes it.
Details
Section titled “Details”- Iceboxing is a placement change, not a lifecycle change: the record’s
placementbecomesiceboxand the previous board geometry is stored asicebox_previous_board_item. - The host enforces the agent-only rule
(
workspace_card_capabilities(...).can_icebox), so the same restriction holds on every client and over the CLI. - CLI equivalent on the host:
offsite-host sessions icebox --session-id <id> --iceboxed/--no-iceboxed. - Restoring a card whose old slot is now occupied places it on the suggested board edge instead of overlapping.
- Move to Icebox lives on the card menu of a board card, on both platforms.
