Shopify CEO Tobi Lütke posted that he is considering banning Claude Code at the company until it supports formats like AGENTS.md and.agents/skills. He cited unnecessary split-brain problems when team members use different AI tools. Replies on X included calls to ban the tool, suggestions for symlinks as a workaround, warnings against single-provider reliance from FactoryAI's Matan Grinberg, and Julien Chaumond hoping the post prompts them to change this.
