Incident Overview
Anthropic issued a takedown request that led to the temporary removal of thousands of GitHub repositories after a code exposure involving its Claude Code tool. The issue occurred during an attempt to remove unintended access to source code.
Code Leak And Takedown Notice
The incident began when a developer identified that a release included access to parts of the source code of Anthropic’s Claude Code command-line application. According to TechCrunch, users examined the code following its exposure. Anthropic responded by issuing a takedown notice under U.S. copyright law to limit further distribution.

Widespread Impact On GitHub
The takedown request affected around 8,100 repositories, according to GitHub. Affected repositories included forks of Anthropic’s public Claude Code project. Users on social platforms reported that some repositories not directly linked to the exposed code were also impacted.
Swift Correction And Corporate Implications
Boris Cherny, Head of Claude Code at Anthropic, said the takedown notice was issued in error and extended to more repositories than intended. According to Anthropic, most notices were withdrawn, with enforcement limited to one repository and 96 forks containing the exposed source code. Company representatives explained that the initial request applied to a broader fork network linked to its public Claude Code repository, which expanded the scope of removals. Following the revision, GitHub restored access to the affected repositories.
Reputation And Future Outlook
Increased scrutiny may follow regarding Anthropic’s internal processes for code management and compliance. As the company expands its AI products and infrastructure, handling of proprietary code and disclosure controls remains relevant for both investors and regulators.
Conclusion
Operational risks related to code distribution and enforcement actions are highlighted by this case. Companies developing AI systems continue to manage exposure risks and platform-level enforcement across large repository networks.
