Go

The Go scaffold uses Go’s standard test tooling, golangci-lint, custom Anvil analyzers, vulnerability checks, coverage, dead-code checks, CRAP scoring, and mutation testing.

go mod tidy
make check

Useful generated targets include make lint, make typecheck, make test, make coverage, make audit, make check, and make quality.

What gets wired in

Anvil adds golangci-lint configuration, custom go vet -vettool analyzers under tools/go-analyzers/, govulncheck, deadcode, Go coverage, CRAP reporting, Go mutation testing, gitleaks scanning, and a generated Nix shell with the required Go tooling.

The custom analyzer bundle targets agentic drift that normal formatters miss: weak error handling, placeholder comments, pass-through wrappers, missing tests, empty tests, tautological assertions, disabled tests without reasons, and structural limits such as file length.

Seed/reference code

Greenfield projects receive internal/seed/ plus a small cmd/app/ entrypoint so agents have package structure, typed errors, constants, enums, structured logging, and tests to imitate. Existing projects skip seed code when Go files or go.mod already exist.
