Anthropic Sends Thousands of Takedown Notices for Claude Code

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. Anthropic representatives have 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.
