/arnold:diff
Quick drift scan using snapshots from previous checks.
When to use it
When you want a fast drift check without a full scan. Arnold compares the current state against the last snapshot from /arnold:check, so only changes since then are analyzed.
Usage
> /arnold:diff
🦕 ARNOLD DIFF (quick scan)
━━━━━━━━━━━━━━━━━━━━━━━━━━
Using snapshot from 2hr ago...
🔴 booking: MAX_CAPACITY changed (20 → 30)
🟢 auth: no changes since snapshot
🟢 payments: no changes since snapshot
🟢 accounts: no changes since snapshot
🔵 calendar-sync: still has doc gaps
1 new drift item since last snapshot.
Run /arnold:check for full analysis.
What it does
- Loads the snapshot from the most recent
/arnold:check - Compares current code state against that snapshot
- Reports only what changed since the last full check
- Much faster than a full check since it skips unchanged files
💡 Tip
Use /arnold:diff for quick mid-session checks. Use /arnold:check for thorough analysis.
