Terminal coding agent. Single binary ccb. Talks to Anthropic (OAuth or API key), Anthropic-compatible endpoints, ChatGPT Codex (OAuth), OpenAI-compatible endpoints (Ollama, DeepSeek, vLLM, …), and Gemini through one agent loop. macOS, Linux, Windows.
Solo-maintained public derivative of Claude Code; baseline reconstructed from the v2.1.88 sourcemap (2026-03-31). See ATTRIBUTION.md. Not affiliated with Anthropic.

> explain what this codebase does
> write tests for src/utils/parser.ts

Ten short interactive lessons walk you through what makes ccb worth using — @ file mentions, permission modes, /rewind and Esc-Esc to undo, background sessions, CLAUDE.md, MCP, skills + hooks, /fork for parallel branches, model dialing, and multi-provider switching. Open one, try it, mark it done. The home banner tracks progress until you've finished all ten.
Requires Bun ≥ 1.3.
