By tashan's measured score: Qsv Data Wrangling, Geosql, BigQuery Data Analytics, Amplitude, DuckDB Skills. the score combines upkeep and freshness, gated by real adoption — every input is public and re-derivable, and no ranking position can be purchased.

How is the ranking calculated?

From public signal only: npm download volume and publish cadence, GitHub push/release recency, contributor count, registry status, and how often a capability appears in real public agent configs. Nobody can pay to change a score, rank, or listing.
