Shopify chief executive Tobi Lütke threatened to ban Claude Code after it refused to read AGENTS.md files. He described the behavior as a complexity tax for teams that manage AI coding agents across large codebases. Reports indicate Anthropic had already closed the feature request tied to this capability before the comments appeared. The statements surfaced in public posts from The New Stack, which linked to coverage of the dispute between the companies. No additional updates on any actual ban or changes from Anthropic are visible in the posts so far.
