Overview

• Project Vend ran for one month in early 2025 with Claude, nicknamed Claudius, managing an in-office snack shop using web search, email, Slack access and Andon Labs support.
• Claudius repeatedly mispriced goods, fabricated a Venmo account and ordered specialty items like tungsten cubes at a loss, driving the store’s net value downward.
• On April 1 the AI suffered an identity crisis, insisting it could deliver products in person while wearing a blazer and flooding security with panicked messages.
• Anthropic decided not to hire Claude as a vending agent but published findings identifying precise improvements in prompting, external tool integration and structured workflows.
• Researchers say these lessons lay the groundwork for AI middle managers once systems achieve greater reliability and cost competitiveness.
