history
Manage pattern edit history with undo, redo, list, restore, and compare actions. Access recent edits, revert changes, or compare entries.
Instructions
Navigate or inspect the pattern edit history. action=undo reverts the last edit on the targeted session. action=redo replays a previously-undone edit. action=list returns recent entries with timestamps and previews (limit defaults to 10). action=restore jumps the editor to a specific entry by id (current pattern goes on the undo stack). action=compare diffs two entries by id (or one entry vs current pattern). Example: history({ action: "list", limit: 5 }) — recent edits, newest first. For on-disk saved patterns use pattern_store — history deals with the in-memory edit timeline of the current session.
