Batch

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

Error	Action
Timeout, rate limit	Retry 3x with backoff (1s, 2s, 4s)
Bad format, missing data	Skip, log, continue
Auth failed, disk full	Abort entire batch

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