The Story

Claude Code is arguably the best AI coding CLI in the world. But it's closed-source.

Then [claude-code-best](https://github.com/claude-code-best/claude-code) did the insane work of decompiling the entire thing — 43 tools, 100+ commands, 5000-line REPL, multi-provider API, MCP protocol, plugin system — all reverse-engineered from the compiled bundle.

**We took that, and actually made it run.**

It wasn't easy. The decompiled code was riddled with landmines:

• API 500 errors — The prompt-caching-scope-2026-01-05 beta header sends cache_control.scope:"global" on system prompts. The server rejects this from non-official builds. We had to disable all experimental betas.
• Empty streaming responses — Opus returns 200 headers but zero events, triggering a non-streaming fallback that sends thinking: {"type":"adaptive"} — which non-streaming doesn't support. We patched adjustParamsForNonStreaming to convert adaptive thinking to budget-based.
• USER_TYPE: undefined — A build-time constant that was never set, causing User-Agent: (undefined, cli). We inject "external" at runtime.
• Gates is not defined — A feature-flagged component referenced but never imported. Even wrapped in false ? ... : [], the assignment still evaluated and crashed.
• Version mismatch — Attribution header checked cc_version, rejecti
