How internal/ packages are organized in a Go project and how errors travel across their boundaries. Use when creating a package under internal/, deciding between domain and layered organization, choosing where to wrap an error, designing a persistence layer, or shaping a config struct that a command fills from flags. Triggers on internal/ package creation, fmt.Errorf wrapping, Store interfaces, JSONStore, handlers/services/models directories, and http.Client construction.
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 Package Architecture **How `internal/` is divided, and which layer is allowed to wrap an error or print one.** ## Organization Start with one package per domain or feature. The grouping matches how work arrives, so a change to downloads touches one directory. ``` internal/ ├── auth/ ├── download/ └── server/ ``` Switch to layered organization once five or more features each need handlers, services, and models. Below that threshold the layers hold one file each and every change edits three directories to accomplish one thing. ``` internal/ ├── handlers/ # HTTP handlers by feature ├── services/ # business logic by feature ├── models/ # data structures └── server/ # server setup ``` Deviating from the structure a project already has is a design change: propose it rather than introducing it inside an unrelated diff. ## Error Handling Packages fall into two kinds, and the kind decides what happens to an error passing through. …

How to install
mdr add tanq16/claudex/go-package-architecture@sha256:ac9c82b80f320655The line at the top of this page pins the label git:20260911.fb4fb25, 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.
