India, March 31 -- Anthropic appears to have accidentally revealed how one of its most important AI products works. A large internal file linked to its agentic AI tool, Claude Code, was made public.

The issue happened when a 59.8 MB JavaScript source map file (.map) which is meant only for debugging was included in version 2.1.88 of the @anthropic-ai/claude-code package on npm. This version went live publicly and exposed the sensitive information.
