// File checkpoint and recovery — auto-quicksaves before destructive commands, manual checkpoints for safe rollback
Prompt rhetoric coach — deterministic scoring and restructuring using Anthropic best practices
Continuous learning — hooks observe failures and prompt reflection, sibling synergy deepens analysis with history and tool discovery
Automatic history search — checks past sessions before web research, planning, and debugging, siblings deepen coverage
Automatic tool discovery across 17 sources — hooks search before planning and after errors, siblings avoid redundant searches
Context preservation with cross-session memory — hooks prompt compaction at high-impact moments, siblings enrich what gets saved

| 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 |

| Historian | File change context from history | find_file_context() explains what happened between checkpoint and now |
| Tool | Purpose |
|---|---|
vigil_save | Create named checkpoint (SHA-256 + gzip dedup) |
vigil_list | List available checkpoints with metadata |
vigil_diff | Preview changes since checkpoint |
vigil_restore | Restore files from checkpoint |
vigil_delete | Remove a checkpoint and free storage |
