Facade in modern Java: one coherent entry point over a subsystem of collaborators, so callers depend on an intention rather than on a sequence. Covers the difference between a facade (simplifies, does not forbid) and a boundary (forbids), the god-facade drift where one class accumulates unrelated use cases, how application services and gateways can play this role while retaining their own boundary responsibilities, and the transaction and fan-out decisions a facade method silently owns. Use…
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
# Facade ## Purpose Give callers one thing to call instead of six, and one vocabulary instead of six. A facade turns "open a session, resolve the tariff, validate the basket, reserve stock, price it, commit" into `checkout.place(basket)`, so the ordering knowledge lives in one place rather than in every caller. The classical pattern **simplifies without forbidding**: the subsystem stays reachable for callers with unusual needs. When direct access is prohibited — the types are package-private, the module does not export them — you have a boundary, which is a stronger and often better design, but it is a different claim and should be stated as one. Inspect target Java, framework, transaction manager and client versions before applying examples. Local sketches use Java 17 syntax; the remote scope example explicitly needs Java 25 preview. Do not upgrade or enable preview merely to adopt Facade. Use existing supported orchestration otherwise. Start with consumer code for the ordinary operation, an advanced supported use and a misuse or failure path. Identify the sequence being simplified, capabilities that must remain available, …

How to install
mdr add robsonkades/agent-skills/gof-facade@sha256:c7bec0c71ac17105The line at the top of this page pins the label git:20260927.9ecadfd, 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.
