Hacubu · x · 2026-09-09

LangChain highlights how Stripe built Kai, its internal 'company brain' serving 10k teammates, on the open-source deepagents harness (29.2k GitHub stars, built on LangGraph, model-agnostic)—with just 1.5 engineers in 2 weeks. Key designs shared on How I AI: projects-as-governance, skill routing plus telemetry, a company-wide skills platform, and minion coding agents. The repo bills deepagents as an opinionated, fully extensible agent harness.
