stacks-arrays · Native Stacks · model-invoked

Use when working with array utilities in Stacks - statistical operations (average, median, mode, standard deviation, z-score, percentile, covariance), array manipulation (unique, flatten, partition, shuffle, sample, move), containment checks, or the Arr facade. Covers @stacksjs/arrays.

Read the skill for the implementation workflow and its current signatures. The Native capabilities catalog maps the package to source and retained evidence; driver limits are explicit.
