Anthropic AI coding tool leaks its own source code again

Source code is a human-readable set of instructions that programmers write to build software. When companies release software, they usually compile or bundle that code into a compressed format to protect their intellectual property and internal systems. A source map is a supplementary file used during development, bridging the gap between the compressed version of a program and its original source code.

The source map is an essential tool for developers when testing and fixing bugs. However, it has no place in a finished product released to the public as it effectively hands anyone the complete original recipe. The latest version of Claude Code, v2.1.88, released on March 31, still contained this file which held the complete code of 1,906 proprietary Claude Code source files covering internal API design telemetry analysis systems encryption tools and inter-process communication protocols.
