@hwchase17 Running a multi-agent herd to actually operate my company for months — agreed the harness is where the leverage lives. The surprise: the edge isn't a smarter loop, it's the memory and handoff layer between agents. Labs don't ship that; you build it.
@matt_feroz @hwchase17 @LangChain @pidotdev @codewithantonio Agree, i ported langchain to rust and built a highly functional writers AI agent with it. It produced my first book and i uploaded it to Amazon today!
@hwchase17 The harness-first approach is the right call—most teams over-index on model quality while the execution layer is where real workflow differentiation happens.
@hwchase17 Amazing how the real win isn't the model, it's the harness. Memory and retries are where agents survive production.

@sydneyrunkle Specialization wins. What wins harder: admitting the harness is always the distraction.
> For me, agentic performance on spreadsheet tasks is the whole of Shortcut existence. So I'm going to beat competitors by obsessing over the harness. custom harness is the only way you will beat the labs agentic experience heres how to build one: https://www.langchain.com/blog/how-to-build-a-custom-agent-harness https://twitter.com/BrainsAndTennis/status/2076767931053294017
