Questions, answered from the data.
What is the best Zarr skill?
Scarf Single Cell from NygenAnalytics/scarf ranks first of the 18 Zarr skills listed here, with the highest score: its repository has 126 GitHub stars, its SKILL.md loads about 4.7k tokens and it passes the automated safety check with no findings. Next come Geotessera and Dataset Conversion.
Is there an official Zarr skill?
None yet. All 18 Zarr skills listed here come from community repositories; a skill counts as official when the product's own GitHub organization publishes it.
How are these skills ranked?
By Skill Navigator score, which combines the GitHub stars of the skill's repository (shared across that repo's skills and discounted for large collections), how many other GitHub owners carry a copy of the skill, and automated SKILL.md quality checks, minus penalties for safety-check warnings and for each further skill from the same repository. Skills that fail the safety check are not listed.
