Use when designing a Go constructor or factory function with optional configuration — especially with 3+ optional parameters or extensible APIs. Also use when building a New* function that takes many settings, even if they don't mention "functional options" by name. Does not cover general function design (see go-functions).
This skill does not declare a tool allowlist. The agent host applies whatever default tools are available at runtime.
