## Variant phrasings

### ZenRows bulk work belongs in Batch - do not fan out fetch or extract per URL

## Why it happens

ZenRows' own agent skill: for many URLs (bulk), use Batch - validate one page with fetch/extract first, then zenrows batch create with a jobs file. The skill is explicit: Batch is the cheap path at scale, do NOT fan out fetch/extract per URL for bulk work. Per-URL fetches each pay full price and serial orchestration multiplies latency; batch amortizes the cost and is the designed scale path.
