| description | File checkpoint and recovery — auto-quicksaves before destructive commands, manual checkpoints for safe rollback |
| triggers | ["PreToolUse"] |
File recovery. Saves checkpoints before dangerous operations, diffs changes, restores files safely.
| Hook | When | Action |
|---|---|---|
| PreToolUse(Bash) | Destructive command detected | Auto-quicksaves affected files (rm, mv, git reset, etc.) |
Token cost: 0 on safe commands, ~30-50 on destructive. The regex matches: rm, rmdir, mv, sed -i, perl -i, git checkout/reset/clean/restore, output redirects.
| Command | Description |
|---|---|
/save-vigil <name> [files] | Create a named file checkpoint |
/restore-vigil [name] | Restore files from a checkpoint |
