The primary manifest — the file an agent reads to learn what this artifact does.
Use this skill when the hard part is not a single job, but deciding where transformations should run and how a data estate should modernize over time. It helps agents reason about ETL versus ELT, pushdown versus external compute, orchestration boundaries, migration sequencing, and proof of parity during modernization.
ETL, ELT, or hybrid transformation patternsDo not assume ELT is always better just because the warehouse is powerful.

Require:
| Rationalization | Reality |
|---|---|
| "Everything should become ELT." | Some workloads still need pre-load shaping, masking, or protocol-specific extraction controls. |
| "The ETL tool is the problem." | The real issue may be unclear ownership, poor contracts, or duplicated logic across layers. |
| "We can rewrite all transformations at once." | Big-bang modernization usually breaks parity, runbooks, and downstream trust. |
