Batch

---

name: Batch description: Process multiple items with progress tracking, checkpointing, and failure recovery.

Before Starting

1. Dry run: Test with 2-3 items first
2. Count: "Processing 47 items, ~2 min estimated"
3. Confirm destructive ops: "This will delete 200 files. Proceed?"

During Processing

• Progress every 10 items: "23/47 complete (49%)"
• Checkpoint every 10-50 items: Save state to resume if interrupted
• On error: Log it, continue with rest (don't abort entire batch)

After Completion

Always report:

✅ 44 succeeded
❌ 3 failed (saved to failed.json for retry)

Error Handling

Check strategies.md for parallel vs sequential decision matrix. Check errors.md for retry logic and rollback patterns.
