Retrieve all unique agent objects from a pipeline.

Recursively traverses the pipeline to collect all distinct agent-based participants. Prevents duplication by tracking already seen agents.

• seen_agents (set, optional) – A set of agents that have already been seen to avoid duplication. Defaults to None.

返回:

A list of unique agent objects found in the pipeline.

返回类型:

list
