Golang Samber Lo

This skill gives Claude working knowledge of samber/lo, the Lodash-inspired utility library that brings 500+ type-safe generic helpers to Go. It covers the core immutable package plus the parallel, mutable, and lazy iterator variants, with clear guidance on when to reach for each one. The skill includes patterns for Map, Filter, Reduce, GroupBy, and error handling variants, plus practical advice on avoiding common mistakes like using lop on tiny slices or assuming lo mutates in place. It's opinionated about preferring stdlib when possible and only optimizing to lop or lom after profiling confirms the need. Apply this when your project imports github.com/samber/lo or when you want Claude to suggest functional transforms instead of manual loops.
