Go norms: idioms that keep a package boring, hexagonal port boundaries, error values over panics and goroutine leaks. Use when editing Go files.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Go Refactoring ## Idioms - Max 40 lines per function - Accept interfaces, return structs - Errors are values — handle them, don't panic - No init() unless absolutely forced by a dependency - No globals — inject dependencies - Receiver name: one or two letters, consistent across methods - Context is always the first parameter ## Hexagonal architecture - Ports (interfaces) in the domain package - Adapters implement ports, never imported by domain - No infrastructure types in domain signatures ## After refactoring - `go vet ./...` — zero issues - `golangci-lint run` — zero issues - `go test -race ./...` — zero failures - Check goroutine leaks with goleak in tests ## Go-specific ladder extensions - Rung 2: `strings`, `strconv`, `slices`, `maps` before any import. - Rung 3: `net/http` before gin/chi/echo; `database/sql` before an ORM. - Rung 4: a stdlib interface fits (`io.Reader`, `fmt.Stringer`)? Use it — don't define your own. - No constructor function if the zero value is usable. - No getter/setter if the field can be public. ## Go performance guardrails - Ladder says "stdlib" but: - `fmt.Sprintf` for string building in a loop? `strings.Builder`. …

How to install
mdr add univers42/claude-deal-with-the-devil/refactor-go@sha256:6b061002c69ada27The line at the top of this page pins the label git:20260930.dc5adef, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
