rifft-langgraph 0.1.0

LangGraph adapter for Rifft

rifft-langgraph

LangGraph adapter for Rifft. Zero-config tracing for LangGraph multi-agent pipelines — one import captures every node execution, inter-node handoff, and the full graph run.

Install

pip install rifft-sdk rifft-langgraph

Usage

Import the adapter anywhere before building your graph:

import rifft
import rifft.adapters.langgraph  # instruments StateGraph automatically

rifft.init(project_id="my-project", endpoint="http://localhost:4318")

from langgraph.graph import StateGraph, END
from typing import TypedDict

class State(TypedDict):
    query: str
    research: str
    output: str

def researcher(state: State) -> dict:
    return {"research": "..."}

def writer(state: State) -> dict:
    return {"output": "..."}

graph = StateGraph(State)
graph.add_node("researcher", researcher)
graph.add_node("writer", writer)
graph.add_edge("researcher", "writer")
graph.set_entry_point("researcher")

app = graph.compile()
result = app.invoke({"query": "what is rifft?"})
# Open http://localhost:3000 to see the trace

What gets traced

Event	Rifft span
graph.invoke() / graph.ainvoke()	langgraph.graph.invoke
Each node execution	agent.execute with langgraph.node, input/output state
Node A → Node B handoff	rifft.agent_to_agent with source_agent_id, target_agent_id, state payload
