In a dramatic turn of events, AI giant Anthropic has accidentally revealed sensitive key details of Claude Code, its major agentic coding tool. This disclosure seemed to stem from a debugging file mistake in a public software package, which offered an unusually deep look into how one of the agentic AI systems operates. The issue began with version 2.1.88 of the @anthropic-ai/claude-code package on npm. This included a 59.8 debug file that was meant for only developers to access. It allowed anyone to access a major chunk of the tool's source code, leading to the exposure of around 512000 lines of TypeScript.
