Stripe just published how their company-wide AI agent works. The bar for building one just dropped to one engineer and one week It is called Kai. Their own words: a coding agent for non-engineers. You chat, it makes reports, dashboards and documents. One engineer built the first version in a week, and 83% of Stripe now uses it weekly. The first trick is what gets loaded. They have 500+ internal tools and 1,000+ skills. All of it at once would drown the model, so nothing loads by default. The model picks which skills the request needs, and those skills bring in only their own tools. Two steps instead of one. The second trick is where code runs. The agent sits outside the sandbox and calls it like any other tool, so code the model wrote can never reach the agent that wrote it. The ceiling they admit to: past about 150 skills, quality starts dropping. They are still working on that one.
