Write, review, and debug Rego policies for goast — the Go AST static analysis tool that lints Go source code with OPA. Use this skill whenever the user wants to create a custom Go lint rule with goast, write or fix a .rego file for `package goast`, understand goast's AST JSON input format, translate a Go coding convention ("forbid fmt.Println", "every function must take context.Context first") into a policy, or debug why a goast policy does not match. Trigger even if the user only says "add a goast rule" or shows a failing `goast eval` run.
