Gopher Code reimplements the full Claude Code v2.1.88 feature set in idiomatic Go, replacing the 500K+ line TypeScript/Node.js/Electron stack. It provides 33 built-in tools for an AI coding agent that can read files, run shell commands, search codebases, and autonomously complete development tasks. The rewrite targets parity with the original while delivering a single-dependency binary that starts in 12ms and cross-compiles to all platforms Go supports.
