known_gaps:
  - Warehouse cost controls differ by pricing model, reservation, edition, region, workload, role, query cache, and whether quotas stop execution or only alert.
  - Agent-generated analysis can multiply costs through retries, exploratory queries, wide scans, cross joins, and dashboard refreshes unless query plans and byte estimates are inspected.

## TL;DR

Data agents need warehouse cost controls and query quotas because one broad generated query can consume budget, slots, credits, or shared capacity.

## Core Explanation

Agentic data workflows often generate SQL iteratively: inspect schema, test filters, refine joins, and compute metrics. That pattern is useful, but it can become expensive when queries scan large partitions, fan out across joins, miss cache opportunities, or retry after failures.

Useful evidence includes warehouse engine, project or account, role, query text, estimated bytes, actual bytes, slot or credit usage, warehouse size, quota limit, resource monitor state, budget alert, query priority, and dry-run result. Agents should surface these fields before running broad exploratory work or recommending a dashboard refresh.

Cost controls should not be treated as only billing artifacts. They are part of safe automation: a query can be syntactically correct and still inappropriate if it exceeds a team quota, blocks shared capacity, or burns through a monthly budget.
