Telling apart the patterns that look alike, so a design is not chosen because a name sounded right. Covers the four wrappers (Adapter, Decorator, Proxy, Facade) and the two questions that separate them, Strategy against State against Template Method against Command, Observer against Mediator, the three creational lookalikes plus the static factory that is not Factory Method, Composite against Decorator, Visitor against Iterator, Command against Event, and Memento against snapshot against event…
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
# Pattern Confusion ## Purpose Stop a design being selected by name similarity. Most of the twenty-three patterns have at least one neighbour with the same structure and a different intent. Distinguish them through collaboration contracts — who knows whom, who decides, what the caller believes it is holding — and documented constraints. A matching call trace alone may not reveal the intended role or axis of change. Naming is useful when it communicates a contract: a protection proxy calls for a bypass review, while a mediator calls for inspection of participant coordination rules. The label alone proves neither exclusive reachability nor future growth. ## The two questions that separate the four wrappers Treat these as shortlist heuristics, not mutually exclusive type tests. Inspect callers, delegation, transitions, failure paths and ownership; one class can serve multiple roles. Inspect ordinary consumer calls, an edge/failure path and public extension contracts to distinguish roles. Keep useful established API names; if intent is still unknown, state the missing evidence rather than requiring a rewrite or an exclusive label. …

How to install
mdr add robsonkades/agent-skills/gof-pattern-confusion@sha256:d0b80566d93c8e91The 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.
