What is this?

This project is a complete Go reimplementation of Claude Code — Anthropic's official TypeScript CLI — rewritten module-by-module in Go, covering all core features: TUI, tool use, permission system, multi-agent coordination, MCP protocol, session management, and more. It understands your codebase, runs tools, and helps you write, review, and refactor code through natural conversation.
🤖 Built entirely by AI agents — zero human-written production code. The initial build (April 2026) was produced by 9 Claude AI agents collaborating in 9 days; since August 2026 a single main Claude session maintains the project against a behavior-parity ledger, with one human owner reviewing and merging.
