Use when structuring a worker, crawler, pipeline, ETL job or integration service whose family is already settled as flat — one distribution on its own by default, and one of several in a repository under the same rules. Defines the four role kinds a flat service divides into and the import contract between them, the packages named for the roles this service actually has, the package and settings class each configured component owns, the single-implementation client holding one pooled transport…
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
# Flat-Layered Architecture — package-by-technology, no ports Covers project layout for services where the ports-and-adapters split (domain/application/ infrastructure/entrypoints, `Protocol` ports, DIP) would add indirection with nothing to protect. The code groups by **technical role**, dependencies point wherever they need to, and an interface is introduced only when a second real implementation is about to exist — not in anticipation of one. This skill assumes the family is already chosen; `architecture-choice` chooses it. **The worked example throughout is a service that fetches from an upstream and lands rows in a store**, because it exercises every role at once. The roles are not that workload: a service that consumes a queue and calls an API, one that renders reports, one that only transforms what it is handed, fills the same four roles and leaves empty the ones it has no use for. A role with nothing in it is not a gap. **The subject is one distribution on its own** — its own package and its own datastores where it has any. A service that shares a repository with siblings is the same service under the same rules with a …

How to install
mdr add wntic/pyhouse/flat-layered@sha256:3f5ff2d251119392The line at the top of this page pins the label git:20261011.4a676ac, 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.
