Vigil Plugin
File recovery. Saves checkpoints before dangerous operations, diffs changes, restores files safely.
Hooks
| 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.
Commands
| Command | Description |
|---|---|
/save-vigil <name> [files] |
Create a named file checkpoint |
/restore-vigil [name] |
Restore files from a checkpoint |
Workflows
Checkpoint (standalone)
vigil_save(name: "before-refactor", files: ["src/auth.ts", "src/middleware.ts"])- Make changes safely
- If something breaks:
vigil_restore(name: "before-refactor")
Checkpoint (with siblings)
vigil_save(name: "before-refactor", files: [...])- If praetorian active: also
praetorian_compact(type: "decisions", ...)to save the reasoning - Make changes — both files and context are now protected
- If something breaks:
vigil_restore(name: "before-refactor")— restore filespraetorian_restore("before-refactor")— restore context
Recovery (standalone)
vigil_list()— see available checkpointsvigil_diff(name: "checkpoint")— preview what would changevigil_restore(name: "checkpoint")— restore files- Optionally:
vigil_delete(name: "checkpoint")— clean up
Recovery (with siblings)
vigil_list()— see available checkpointsvigil_diff(name: "checkpoint")— preview changes- If historian active:
find_file_context("filename")to understand what changed and why vigil_restore(name: "checkpoint")— restore files- If praetorian active: restore matching compaction for context
Sibling Synergy
| Sibling | Value | How |
|---|---|---|
| Praetorian | Context saved alongside files | Pair vigil checkpoints with praetorian compactions for full state recovery |
| Historian | File change context from history | find_file_context() explains what happened between checkpoint and now |
