Gff Gtf Pushdown Regression | Agent Skills Atlas

About this skill

Validate polarsbio GFF/GTF predicate and projection pushdown for correctness and performance against real GENCODE data, using oxbow as an independent reference reader. Use this whenever you touch the pushdown path — the predicate translator (predicatetranslator.py), the shared helpers (pushdown.py), the scan call sites (io.py overlapsource / the GFF/GTF select() wrapper, utils.py, pileupop.py), scangtf/scangff, or anything about predicate/projection pushdown, filter pushdown, attribute fields, or the issue 396 / PR 407 work — and any time you want to confirm a filtered or projected scan returns identical results with pushdown on vs off, or to benchmark how much pushdown actually speeds a query up. Reach for it before claiming a pushdown change is correct.
