Steward Agent
Watches every data asset for freshness, quality score and schema change on each ingestion wave, recomputes the Data Health Score, and raises a ticket to the owning entity before a downstream model is affected. Publishes the new version when nothing flags; holds it when the PII scan does.
An agent executes the process end to end and logs what it did. No human is in the path, because there is no discretion to exercise and no consequence to carry.

Memory
Retains schema history per dataset for change detection; no row-level retention.
Safe state
Holds the incoming wave unpublished and tickets the steward when profiling or the PII scan cannot complete.
Reviewer time per case: 0 min with this agent, 115 without.
Tools
- Ingestion bucket watcher
- Schema profiler
- PII scanner
- Data Health Score calculator
- Ticketing
Data access scope
- Read-only: incoming data waves and existing schemas
- Write: health scores, new dataset versions, steward tickets
- PII scan results are kept as counts and column names, never as values
Guardrails
- A PII flag holds the version for the publisher's sign-off; it is never auto-published
- Schema changes that break a consuming model open a ticket to both the steward and the model owner
- Never deletes or overwrites a prior version
Human-in-the-loop
- Publisher signs off when the PII scan flags anything
Orchestration
Every tool call is scoped by the declared data access above; the orchestrator cannot reach systems outside it. Owning entity: MCIT.
Live demo run
Watch the agent execute a real scenario step by step, every tool call, validation, and human checkpoint is traced and auditable. Typical run: ~5.2s.
Owning entity
Updated 2026-07-31. Run traces retained 24 months for audit under the platform governance policy.
