When the Lobster Met the Leak: How Claude Code's Source Code Exposure Could Supercharge China's AI Agent Revolution

April 7, 2026 The Collision of Two Stories In late March 2026, two seemingly unrelated developments converged to reshape the AI agent landscape in China. First, an open-source AI agent framework affectionately nicknamed "the lobster" (龍蝦) by Chinese users had already ignited a nationwide frenzy — millions were "raising lobsters," customizing AI agents to automate everything from e-commerce listings to financial workflows. Then, Claude Code — Anthropic's flagship AI coding agent — had its source code exposed, with the full TypeScript implementation spilling into the open via what has been reported as an inadvertent package distribution. For China's booming AI agent ecosystem, this was rocket fuel. What the Leak Contained — and Why It Matters The Claude Code leak was not a model weights breach. The "brain" — Anthropic's Claude model — remains proprietary. But the "skeleton" — the engineering that makes an AI agent actually useful — was fully exposed: Agentic architecture patterns: How Cl
