Presets

Presets are higher-level, opinionated building blocks that compose Flowneer's core primitives into common patterns. Unlike plugins (which add capabilities to a FlowBuilder), presets return a fully wired FlowBuilder ready to run.

When to use presets vs plugins

	Plugins	Presets
What they are	Capabilities added to a flow	Pre-built flow templates
Usage	.withTiming(), .withMemory()	createAgent(...), ragPipeline(...)
Extension point	FlowBuilder.extend([...])	Call the function, get a FlowBuilder
Composable?	Yes — chain on any flow	Yes — extend the returned FlowBuilder

All presets return a FlowBuilder, so they compose freely with plugins and each other.
