DECISION-READY SQL — FAST

Validate AI-generated SQL before it ships decisions.

Paste your goal + SQL. GroupBySQL checks safety, clarity, and evidence alignment — then returns one primary gap and one next-best fix direction.

What the Audit Engine verifies in seconds

• Read-only structure checks (SELECT/WITH only)
• Blocks vague goals (“performance”, “usage”, etc.)
• Confirms time grain + metric base match the goal
• One primary gap + one next-best fix direction

How the Audit Engine Verifies in Seconds

  • ✓ Goal-safe structure: Enforce SELECT-only for security.
  • ✓ Block fuzzy explanations: Reject vague goals so results are actually testable.
  • ✓ Pressure-test alignment: Catch “looks right” SQL that answers the wrong question.
Real-World Example

WAU looked up — but the query counted events, not users.

-- BEFORE (inflated): counts events SELECT DATE_TRUNC('week', event_ts) AS wk, COUNT(*) AS wau FROM events GROUP BY 1; -- AFTER (correct): counts unique users SELECT DATE_TRUNC('week', event_ts) AS wk, COUNT(DISTINCT user_id) AS wau FROM events GROUP BY 1;
What’s Wrong
  • Metric base mismatch (events vs users)
  • Wrong time grain for the stated goal
  • Missing dedupe logic for “unique” metrics
Audit Fix
  • Confirm entity: user / account / session / event
  • Enforce the time grain required by the goal
  • Add dedupe direction (DISTINCT / window / key strategy)

Why I Built GroupBySQL

Most SQL resources teach you to pass tests. Real jobs demand clear thinking, messy data, and executive outcomes. GroupBySQL exists to help teams validate AI-generated SQL so decisions don’t ship with hidden metric or grain errors.
