Claude runs in Microsoft Foundry, but Anthropic still processes prompts, flagged content may get human review, and some setups can leave your region. Ask: who processes data, where, and who sees it?
Anthropic's Claude Science ships every figure with its code, environment, and chat history. Ask the same of any AI analysis tool: months later, can a colleague redo this chart without asking the AI?
In Anthropic's internal case, the same Claude went from under 21% to over 95% accuracy on company numbers once sources and definitions were curated, then fell to about 65% after a month unmaintained.
When AI should stop can't depend on it saying "I'm not sure." Make stops visible events: missing fields, conflicting sources, an outbound next step, unknown state. Leave a record others can pick up.
