Anthropic accidentally releases source code for Claude AI agent

Anthropic inadvertently released source code for its popular Claude AI agent, raising questions about its operational security and sending developers on a search for clues about the startup’s plans.

“Earlier today, a Claude Code release included some internal source code. No sensitive customer data or credentials were involved or exposed,” an Anthropic spokesperson said in an emailed statement. “This was a release packaging issue caused by human error, not a security breach. We’re rolling out measures to prevent this from happening again.”
