Auditing data warehouse source health

This skill produces a project-wide audit of the source and sync side of the data warehouse pipeline — source connections, sync schemas, and webhook push channels. Use it when the user wants a summary of what's broken with their imports, not a deep-dive on one sync. The deep-dive on individual failures is diagnosing-failed-warehouse-syncs; this skill is the scan that tells them where to look first.

The same underlying endpoint (data-warehouse-data-health-issues-retrieve) also reports materialized-view, batch-export-destination, and transformation issues. Materialized views are covered by auditing-warehouse-view-health. Destinations (batch exports) and transformations are owned by other products — surface them if they appear, but route them to the relevant team rather than diagnosing here.

When to use this skill

• "Why are my imports failing?" / "What's broken with my sources?"
• "Why is my warehouse data stale?"
• The user is new to a project and wants to know which sources they've inherited and whether they're healthy
• Weekly or monthly review of source/sync health
• Dashboards are stale and the user isn't sure which source is at fault
