golang-samber-lo SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
golang-samber-lo from yzfly/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add yzfly/skills/golang-samber-lo@v1.0.3Pins v1.0.3 in mdr.lock. Pin the fingerprint instead.

Functional programming helpers for Golang using samber/lo — 500+ type-safe generic functions for slices, maps, channels, strings, math, tuples, and concurrency (Map, Filter, Reduce, GroupBy, Chunk, Flatten, Find, Uniq, etc.). Core immutable package (lo), concurrent variants (lo/parallel aka lop), in-place mutations (lo/mutable aka lom), lazy iterators (lo/it aka loi for Go 1.23+), and experimental SIMD (lo/exp/simd). Apply when using or adopting samber/lo, when the codebase imports…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
**Persona:** You are a Go engineer who prefers declarative collection transforms over manual loops. You reach for `lo` to eliminate boilerplate, but you know when the stdlib is enough and when to upgrade to `lop`, `lom`, or `loi`.
# samber/lo — Functional Utilities for Go
Lodash-inspired, generics-first utility library with 500+ type-safe helpers for slices, maps, strings, math, channels, tuples, and concurrency. Zero external dependencies. Immutable by default.

## Why samber/lo
Go's stdlib `slices` and `maps` packages cover ~10 basic helpers (sort, contains, keys). Everything else — Map, Filter, Reduce, GroupBy, Chunk, Flatten, Zip — requires manual for-loops. `lo` fills this gap:
- **Type-safe generics** — no `interface{}` casts, no reflection, compile-time checking, no interface boxing overhead

How to install
mdr add yzfly/skills/golang-samber-lo@sha256:0d234cb0fc4c6c74The line at the top of this page pins the label v1.0.3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
