hermes checkpoints
Inspect / prune / clear ~/.hermes/checkpoints/ (the shadow store used by /rollback). Run with no args for a status overview.
Inspect and manage the shadow git store at ~/.hermes/checkpoints/ — the storage layer behind the in-session /rollback command. Safe to run any time; does not require the agent to be running.
From the official Hermes Agent CLI reference.
