bench-langchain 0.1.0

Bench adapter for LangChain — auto-instrument every chain, agent, and LLM call.

bench-langchain

LangChain callback adapter for Bench. It records chain, LLM, and tool runs through the zero-dependency bench-observe SDK.

python -m pip install bench-langchain

import os
from bench import observe
from bench_langchain import BenchCallbackHandler

agent = observe(
    api_key=os.environ["BENCH_KEY"],
    agent="my-langchain-agent",
    framework="langchain",
)
handler = BenchCallbackHandler(agent)

result = chain.invoke(
    {"input": "Research this question"},
    config={"callbacks": [handler]},
)

New agents hide raw inputs and outputs by default. Bench also redacts common secret and PII patterns before storage.
