Top use cases
Save the prompts you reuse and regenerate diagrams every time your stack changes.
Show upstream/downstream impact for critical metrics
Map lineage from ingestion to semantic layer to dashboards
Expose owners and runbooks next to every hop
Summarize incident impact for postmortems
Workflow that ships
List sources, transforms, marts, and dashboards. Include owners and refresh cadence.
Ask AI to draw lineage left-to-right with edge labels for freshness and contracts.
Highlight critical paths and attach runbooks for each hop.
Export snapshots for audits and keep prompts to regenerate after schema drift.
Prompt recipes
Copy, tweak, and save in your repo so regenerations stay consistent.
"Draw lineage for ARR metric from Salesforce to staging to dbt models to semantic layer to Tableau dashboards. Include owners and SLAs."
"Generate column-level lineage for customer_id across ingestion, warehouse, and BI. Show PII handling."
"Create an incident view: which dashboards break if the payments table is delayed by 2 hours?"
Quality checklist
Edges show freshness, contracts, and failure alerts.
Columns with PII are flagged and traced through the flow.
Owners and escalation channels are visible for every node.
Dashboards link back to metrics definitions and tests.

FAQ
What level of detail is best for lineage diagrams?
Start at table/model level for clarity. Add column-level for PII or high-risk metrics, but avoid clutter for routine paths.
How do I keep lineage diagrams current?
Pair AI prompts with metadata exports from your catalog or dbt docs, then regenerate diagrams weekly or after large PRs.
Can I share lineage with business teams?
Yes. Use a simplified view that highlights metric names, owners, and refresh schedules rather than technical table names.
