Checkpoints are created automatically after file-modifying tool calls (WriteFile, EditFile). Each checkpoint records:
  • File snapshots (before/after content, unified diff)
  • Operation type (created, modified, deleted)
  • Line statistics (additions/deletions)
  • Associated user message and timestamp

​
Accessing Checkpoints

  • Press Escape twice or use /checkpoints to open the checkpoint viewer
  • Navigate with Up/Down, press Enter to view diff or restore

​
Checkpoint Viewer

In the checkpoint viewer:
  • Up/Down - Navigate checkpoints
  • Enter - View diff / restore options
  • Escape - Back / close
Each checkpoint shows:
  • Timestamp
  • File path
  • Operation type (created/modified/deleted)
  • Line changes (+/-)
You can restore a checkpoint to revert to the previous state.
