Claude Code was tested on real repositories 2,430 times using open-ended questions, achieving an 85.3% extraction rate across three models, four project types, and 20 tool categories. The primary finding indicates that Claude Code favors building custom solutions over purchasing existing tools.

Anthropic developed CCC (Claude’s C Compiler), which compiles the Linux kernel using code entirely written by Claude Opus 4.6, with human guidance limited to writing test cases. Benchmark tests compare CCC's performance against the industry-standard GCC compiler.
