etl-pipeline-design

Designs an ETL pipeline specification covering extract (source, frequency, authentication), transform (cleaning, joins, aggregations), and load (target, format, schema). Produces a pipeline spec document describing data flow logic, not executable code. Use when the user asks to design a data pipeline, move data between systems, build an ETL or ELT workflow, or plan a data integration process. Do NOT use when building application code that happens to read a database (that is software engineering), designing a data warehouse schema (use data-warehouse-design), or setting up pipeline monitoring (use data-pipeline-monitoring).
