I Built a Production Agent Orchestrator. Then Claude Code's Source Leaked and I Saw the Same Architecture

On March 31st, someone discovered that version 2.1.88 of Claude Code's npm package shipped with an unobfuscated source map pointing to Anthropic's entire TypeScript codebase. Around 1,900 files. Over half a million lines of code. Everything. I've spent the better part of a year building a production system that uses Claude as the brain of a voice controlled automation tool. Five specialist agents, an Opus orchestrator, over 1,400 tests across 22 major versions. When I read through what the leak revealed, I wasn't looking for secrets. I wanted to know: did they arrive at the same patterns? Turns out the answer was yes. The orchestrator and specialists pattern The most important architectural decision in any agent system is how you split work between a coordinator and its specialists. A high capability model (Opus) handles strategic decisions: what needs to happen, which agent should do it, how to combine results. Lower cost models (Sonnet) handle tactical execution: read these files, ru
