Artificial intelligence firm Anthropic has accidentally revealed the source code for its popular coding tool Claude Code. The leak occurred Tuesday morning when the company published version 2.1.88 of Claude Code to the public npm registry and inadvertently included a source map file,

The developer has issued a copyright takedown request in bid to prevent competitors from cloning coding tool’s features.

Anthropic accidentally released part of the internal source code for its AI-powered coding assistant Claude Code due to "human error," the company said Tuesday.

Source material powering Anthropic's Claude Code leaked for the second time in just over a year, publicly exposing the AI coding tool's full architecture, unreleased features and internal model performance data.

Claude Code has seen massive adoption over the last year, and its run-rate revenue had swelled to more than $2.5 billion as of February.

After details of a yet-to-be-announced model were revealed due to the company leaving unpublished drafts of documents and blog posts in a publicly visible data cache, Anthropic has been hit with yet another lapse in protocol by inadvertently publishing internal source code for its AI coding assistant,

Hundreds of thousands of lines of code were exposed, giving researchers insight into upcoming models and internal architecture.

Anthropic PBC has accidently exposed the source code for its Claude Code command-line interface tool through a packaging error that led to the inclusion of sensitive files in a publicly distributed node package manager or npm release.
