Abstract Factory in modern Java: the pattern exists to keep a _family_ of related objects mutually consistent when the family varies, not to centralise construction. Covers the family invariant that justifies it, when existing composition resolves the deployment-time case, when per-request or per-tenant selection benefits from a family provider, and how to express it as a record of suppliers or a sealed provider rather than a four-level interface hierarchy. Use when a factory interface is…
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
# Abstract Factory ## Purpose Select related products together and preserve their compatibility. Abstract Factory alone does not make mixing impossible: callers can combine products from different factories, and a public aggregate constructor can accept mismatched products. State the enforcement boundary: trusted assembly with contract tests, validated family identities, family-typed APIs, or encapsulated operations that never expose mixable products. Shared family identity may also require the same transaction/session instance, not merely the same vendor or format. Choose the mechanism for the promised misuse boundary: tests support trusted assembly but do not reject arbitrary caller combinations. A shared generic family parameter distinguishes types, not two runtime sessions of the same type; use a checked owner identity or hide the products when that distinction is required. If there is no invariant binding the products to each other, this is not Abstract Factory. It is a bag of factory methods, and it should be several separate providers or none at all. Start with ordinary consumer calls, a relevant advanced use (such as a plugin or session-owned …

How to install
mdr add robsonkades/agent-skills/gof-abstract-factory@sha256:eadf7e91299d8882The 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.
