agents.chain.declarative_chain¶

Declarative chain building for complex agent workflows.

Provides declarative specification and building of complex agent chains with branching, loops, and conditional execution.

Classes¶

`BranchSpec`	Specification for conditional branching.
`ChainBuilder`	Builder for creating declarative chains.
`ChainSpec`	Complete specification for a declarative chain.
`DeclarativeChainAgent`	Agent that executes a declaratively defined chain.
`LoopSpec`	Specification for loops in the chain.
`NodeSpec`	Specification for a single node in a chain.
`SequenceSpec`	Specification for a sequence of nodes.

Functions¶

complex_rag(*args, **kwargs)

Create a complex RAG chain using declarative building.
