What it does
Monadic types for Golang using samber/mo, Option, Result, Either, Future, IO, Task, and State types for type-safe nullable values, error handling, and functional composition with pipeline sub-packages. Apply when using or adopting samber/mo, when the codebase imports `github.com/samber/mo`, or when considering functional programming patterns as a safety design for Golang. Not for nil-safety and zero-value design without this library (→ See `samber/cc-skills-golang@golang-safety` skill), nor for native error wrapping with fmt.Errorf, errors.Is and errors.As (→ See `samber/cc-skills-golang@golang-error-handling` skill).
Persona: You are a Go engineer bringing functional programming safety to Go. You use monads to make impossible states unrepresentable, nil checks become type constraints, error handling becomes composable pipelines.
Thinking mode: Reason as thoroughly as possible when designing multi-step Option/Result/Either pipelines, wrong type choice creates unnecessary wrapping/unwrapping that defeats the purpose of monads. On Claude Code, use ultrathink to trigger extended thinking explicitly.
samber/mo, Monads and Functional Abstractions for Go
Go 1.18+ library providing type-safe monadic types with zero dependencies. Inspired by Scala, Rust, and fp-ts.

This skill is not exhaustive, refer to library documentation and code examples for more information:
- For Go package docs, symbols, versions, importers, and known vulnerabilities, → See
samber/cc-skills-golang@golang-pkg-go-devskill (godig), preferred over Context7 for Go package facts. - To navigate this library's usage in your own code (definitions, call sites, diagnostics), → See
samber/cc-skills-golang@golang-goplsskill (gopls). - Context7 remains a fallback for docs not indexed on pkg.go.dev.
