Design and implement a Flowneer plugin. Use for: writing a FlowneerPlugin object, choosing lifecycle hooks (beforeFlow/beforeStep/wrapStep/afterStep/onError/afterFlow), applying StepFilter to scope hooks, adding TypeScript types via declaration merging, registering a new step type with CoreFlowBuilder.registerStepType(), building a builder method that pushes a step descriptor, composing multiple hooks in one plugin, and packaging a plugin for reuse.
Deep-dive skill for Flowneer's graph plugin and JsonFlowBuilder preset. Use for: building DAG flows with withGraph + .addNode()/.addEdge()/.compile(), using withExportGraph / withExportFlow to serialise flow structure, building config-driven flows with JsonFlowBuilder.build() / .validate() / .registerStepBuilder(), combining graph topology with JsonFlowBuilder via a custom FlowClass, registering custom step-type compilers.
Build a Flowneer flow using FlowBuilder. Use for: creating FlowBuilder flows, adding steps with .then()/.branch()/.loop()/.batch()/.parallel(), using the graph plugin (withGraph + .addNode()/.addEdge()/.compile()), building config-driven flows with JsonFlowBuilder, wiring middleware/plugins with FlowBuilder.extend(), designing shared state types, implementing agentic loops, adding per-step middleware like withTiming/withRateLimit/withCircuitBreaker.
