golang-samber-mo

golang-samber-mo is an agent skill from the samber cc-skills-golang collection for using monadic types in Go with the samber/mo library. The library, which needs Go 1.18 or later, provides types such as Option, Result, Either, Future, IO, Task and State, for type-safe handling of values that may be absent and of errors, and for composing those steps into pipelines. Its persona is a Go engineer who brings functional safety to Go: monads are used to make impossible states unrepresentable, so nil checks become type constraints and error handling becomes a composable pipeline. The skill warns that choosing the wrong type for a pipeline creates unnecessary wrapping and unwrapping, which defeats the purpose, so the choice between Option, Result and Either should be made carefully when designing a multi-step pipeline. It is useful for developers who want more structure than nil checks and repeated error checks provide, and who are comfortable with a functional style. Teams new to the style should weigh it against Go's idiomatic error handling, which many Go developers prefer. The skill points to official references for the library, and notes that it is not exhaustive. It is listed on skills.sh, where the page shows install counts and GitHub stars for the collection.
