POST/v2/agents/sessions/{session_id}/checkpoints/{checkpoint_id}/rollback

RollbackToCheckpoint rewinds a session to a checkpoint.

In-place restore: boots a fresh sandbox from the checkpoint and atomically swaps the session's sandbox pointer to it, so the session keeps its same session_id; the old sandbox is then torn down.

  • IdempotentThe SDK sends Idempotency-Key, so a retried request is only applied once.
