Anthropic is racing to contain the fallout after accidentally exposing the underlying instructions it uses to direct Claude Code, the popular artificial-intelligence agent app that has won the company an edge with developers and businesses. By Wednesday morning, Anthropic representatives had used a copyright takedown request to force the removal of more than 8,000 copies and adaptations of the raw Claude Code instructions—known as source code—that developers had shared on programming platform GitHub. The leak of “some internal source code” didn’t expose any customer information or data, a spokesman for Anthropic said. Nor did it divulge the valuable inner mathematics—sometimes called weights—of the company’s expensive and powerful AI models.
