Prototype in modern Java: producing a new object from an existing instance's state, when the configuration is expensive or the concrete type is unknown to the caller. Covers why Cloneable/clone() needs an explicit contract and what replaces it, the deep-versus-shallow decision on graphs with identity and cycles, when immutable values can be shared, the torn-copy hazard under concurrency, and the identity rules when copying persisted objects. Use when clone() or Cloneable appears, when an…
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
# Prototype ## Purpose Create a new object by copying a configured one. The pattern applies when the state that makes an object useful was assembled at runtime and is costly or undesirable to re-derive — a document template, a pre-wired processing pipeline, a scenario fixture — or when the copier does not know the concrete class it is duplicating. In modern Java the pattern is often a warning. Immutable values usually can be shared, and Java's built-in copying mechanism (`Cloneable`) has a weak contract. What survives should normally use explicit copy constructors or copy factories; interoperability with a hierarchy that already has a correct `clone()` contract is a constrained exception, not a reason to spread that API. Java 17 is the baseline for these partial examples; no preview features are required. Inspect compiler settings, copy APIs, persistence mappings/provider and ownership before applying them. Do not upgrade Java or persistence libraries merely to fit an example. Deliver the copy purpose, per-field ownership/identity policy, concurrency precondition and relevant validation or gaps. …

How to install
mdr add robsonkades/agent-skills/gof-prototype@sha256:770fb030b4e56273The line at the top of this page pins the label git:20260923.832673e, 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.
