# dltHub AI Workbench data quality toolkit: schema-aware checks that route their own fixes

**[dltHub](https://daily.dev/sources/dlthub)** · 7 min read · 1 upvotes · 0 comments

## Summary

dltHub's AI Workbench data quality toolkit bootstraps checks directly from dlt's existing schema metadata (primary keys, non-nullable columns, uniqueness hints), samples columns before writing any rules, and embeds checks as decorators inside pipeline.run() via @dq.with_checks and @dq.with_metrics. Results are stored in destination tables (_dlt_checks, _dlt_dq_metrics) for querying or alerting. When failures occur, an LLM routes the fix to the appropriate toolkit: ingestion issues go to rest-api-pipeline, modeling issues to transformations, anomalies to data-exploration. This contrasts with tools like Great Expectations, which only report failures without routing fixes. The toolkit is part of dltHub Pro with a free trial available.
