Bridge in modern Java: separating an abstraction hierarchy from an implementation hierarchy so the two vary independently instead of multiplying into N×M classes. Covers the two-axis test that distinguishes it from Strategy, what to do when the matrix has illegal combinations, how implementor contracts account for backend cost and failure without losing required capabilities, and the thread-safety contract that belongs to the interface rather than to each implementation. Use when class names…
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
# Bridge ## Purpose Stop a class hierarchy multiplying. When a design varies along two independent axes and both are expressed as subclasses, the variation-specific class count is their product: `EncryptedS3Store`, `PlainS3Store`, `EncryptedFileStore`, `PlainFileStore`, and two more when one axis gains a third member. Bridge makes one axis the abstraction, the other an implementor interface held in a field. The variation implementations grow by their sum; shared interfaces and wiring add other types. Mechanically this is "hold an interface in a field and delegate" — which is why the pattern is rarely named in Java code that already does it. Naming it is still worth something: it says the field is not an incidental collaborator but the second axis of the design, and that new backends are expected to arrive without touching the abstraction. Start from representative consumer operations, required advanced capabilities and failure/lifecycle expectations. Reuse accepted boundary decisions, change history and existing tests to establish the two responsibilities; names and type counts are clues. Ask only for missing evidence that could …

How to install
mdr add robsonkades/agent-skills/gof-bridge@sha256:35053ff19c59c51bThe line at the top of this page pins the label git:20261016.c769bd8, 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.
