Claude Code Working

claude-code-working

A working reverse-engineered Claude Code CLI codebase rebuilt from source analysis to reproduce the original terminal workflow, architecture, and engineering behavior.

Start with the architecture docs

Current focus:

- [x] The codebase runs and passes baseline type checks.
- [x] The monorepo and engineering scaffolding are in place.
  - [ ] Biome formatting is intentionally conservative to avoid massive diff churn.
  - [x] The build pipeline produces runnable Node and Bun output.
- [x] The documentation set is available in English.
- [ ] More tests can still be added to improve confidence and stability.

Quick start

Environmental requirements

You must have the latest version of bun, otherwise there will be a bunch of weird bugs!!! bun upgrade!!!

- Bun >= 1.3.11
- Conventional way to configure CC, each major provider has its own configuration method

Installation

Run

The build uses code splitting multi-file packaging (build.ts), and the product is output to the dist/ directory (entry dist/cli.js + about 450 chunk files).

The built version can be started by both bun and node. You can start it directly by publishing it to a private source.

If you encounter a bug, please raise an issue directly and we will resolve it first.
