Is Claude Watermarking Code? What Developers Need to Know

Automated excerpt

Since August 2, 2026, Claude embeds a statistical watermark in its text output, and Anthropic's coverage list explicitly includes Claude Code. Claude Code output falls under the same watermarking as everything else Claude generates, since it's applied at the model level rather than per-product. The watermark has the same core limitation in code that it has in prose, and the low signal in code makes it worse rather than better.
