What it is

SQLFix — definition

SQLFix turns natural-language questions into read-oriented SQL drafts with deterministic safety checks (e.g. destructive statements) — decision-support for analysts, not auto-exec.

What this is NOT

  • Not a law firm, GRC platform, or ISO certification body.
  • Not a guarantee that drafted policies will satisfy every regulator or auditor.
  • Not legal advice — have counsel review high-stakes agent policy packs.

Controller / Processor — When packs mention privacy roles, we use GDPR Art.4 labels: Controller and Processor (decision-support only).

Why packs stall

Policies change. Agent gaps appear late.

New rules, new risk

Each regulatory update can leave agent tools, data classes, and escalation paths out of sync.

Docs vs runtime

When the PDF lives apart from the agent runtime, blind spots show up in production.

Manual rewrites

Hand-editing checklists for every domain quietly drains engineering and compliance time.

Issues after ship

Gaps often surface only after an audit, incident, or customer questionnaire.

What you get

Paste. Generate. Export.

Generator-style deliverables for agent governance — review with counsel before production.

Policy checks

Condition + action rules an agent runtime can evaluate.

Compliance checklist

Human-readable duties so owners see gaps before go-live.

EU AI Act mapping

Theme pointers for high-risk obligations — not conformity certification.

Exportable rules
