## How the Build Works

The original Claude Code is built with **Bun** using compile-time intrinsics (`feature()`, `MACRO`, `bun:bundle`). This project uses **esbuild** as a best-effort replacement:

1. **Transform**: `feature('FLAG')` → `false`, `MACRO.VERSION` → `'2.1.88'`
2. **Stubs**: Auto-generates stubs for 108 missing internal modules (feature-gated, dead-code-eliminated in the original build)
3. **Bundle**: esbuild bundles everything into a single ESM file
4. **Patch**: Replaces esbuild's `__require` shim with Node.js `createRequire` for CJS interop

The build produces a self-contained `dist/cli.js` that only requires Node.js >= 18.

## Requirements

- Node.js >= 18
- npm >= 9
- An Anthropic API key or compatible endpoint
