Agent that triages BigQuery schema changes and files fix tickets in Linear

Goes beyond listing affected models. When a BigQuery table's schema changes, an agent gathers the evidence — the column diff, the dbt models that reference it from GitLab, and recent query usage from Axiom — and reasons about real impact: which models will actually break, which are cosmetic, and what the fix likely is. It then drafts a Linear ticket with a clear remediation summary and assigns it to the owner.

Use it when a raw blast-radius list still leaves a human to interpret severity and write up the fix. The agent does that judgment work, so your data team gets actionable, pre-scoped tickets instead of another alert to triage by hand.

1. 1A webhook fires when a schema change is detected on a tracked BigQuery table.
2. 2The agent reads the column diff and queries dbt lineage from GitLab.
3. 3It pulls recent query usage from Axiom to gauge whether anything live depends on the change.
4. 4It reasons over the evidence to classify severity and draft a remediation plan.
5. 5It opens a scoped Linear ticket assigned to the resolved owner with the assessment attached.
