Score: 6.5/10 (Innovation: 6, Technical: 6, Documentation: 8, Utility: 6)

tff is a static analysis tool for data transformation projects (dbt, SQLMesh, Dataform) that enforces architectural boundaries, detects duplicate transformation logic, and provides a health score for CI gating. It's interesting because it operates on the transformation DAG as a whole rather than individual files, addressing a gap in existing SQL linters.

Target audience: data engineers, analytics engineers, devops
