Summary	Pass a request through a sequence of handlers until one handles it or the chain ends.	—	—
Intent	Pass requests along a chain of handlers until one of them handles the request or the request reaches the end of the chain.	Define an object that encapsulates communication between a set of objects, keeping them from referring to each other directly.	Specify the kinds of objects to create using a prototypical instance, and create new objects by cloning that prototype.
Decision factors
Problem	A request must pass through multiple possible handlers, but the sender should not need to know which handler will process it.	Multiple objects need to coordinate behavior, but direct references between them create tight coupling and complex dependencies.	Creating new objects from scratch can be expensive or repetitive when the system needs many similar variants.
Tradeoffs	Requests can become harder to trace because control flows through multiple handlers. A long chain may add overhead if many handlers are checked on every request. It keeps handler logic isolated and easier to extend.	The mediator can become large and complex if it takes on too much coordination logic. Centralizing behavior can make the mediator a single point of failure if it is poorly designed.	Can be difficult if the object graph contains deep references that need custom clone behavior May require careful handling of mutable state to avoid shared-reference bugs

Integration notes	Chain of Responsibility is useful for validation pipelines, support routing, approval flows, and any system where requests may be processed by different handlers in sequence.	Mediator is useful for chat systems, form coordination, workflow orchestration, and any domain where many components must collaborate without knowing about each other.	Prototype is useful when object creation is expensive, when many near-identical objects are needed, or when cloning preconfigured templates is simpler than rebuilding them.
