CleverActors

CleverActors is the reactive agent framework used by CleverAgents and CleverRouter.

It provides a Python library that lets a host application:

• Parse CleverAgents v2 YAML configuration files (with Jinja2 templates and ${ENV_VAR} interpolation).
• Validate configuration against the built-in schema validator.
• Create reactive agent networks with RxPy streams, LangGraph graphs, or hybrid pipelines of both.
• Run single-shot prompts, interactive CLI sessions, or stream-based processing via the ReactiveCleverAgentsApp orchestrator.

Install

pip install "cleveractors @ git+https://git.cleverthis.com/cleverlibre/cleveractors@master"

Quick start

from cleveractors import ReactiveCleverAgentsApp

app = ReactiveCleverAgentsApp(config_files=["config.yaml"])
result = await app.run_single_shot("Hello, agents!")
print(result)

Using agents directly

from cleveractors import Agent
from cleveractors.agents.llm import LLMAgent

agent = LLMAgent(
    name="assistant",
    config={"provider": "openai", "model": "gpt-4o", "system_prompt": "Be helpful."},
)
response = await agent.process_message("What is 2+2?")
print(response)

LangGraph workflows

from cleveractors.langgraph import LangGraph, Node, NodeType, GraphState

graph = LangGraph(name="my_workflow", config={})
graph.add_node(Node(name="start", node_type=NodeType.AGENT, agent="assistant"))
graph.add_node(Node(name="end", node_type=NodeType.END))
graph.add_edge("start", "end")
result = await graph.execute({"message": "Hello"})

Reactive stream routing

from cleveractors.reactive.stream_router import ReactiveStreamRouter, StreamType

router = ReactiveStreamRouter()
stream = router.create_stream({"name": "pipeline", "type": StreamType.HOT})
router.send_message("pipeline", "Process this message")
