cc-switch 是一个开源的 Claude Code 多账号 / 多供应商切换工具（核心作者另有其人）。cc-switch is an open-source account/provider switcher for Claude Code (its core author is someone else).
我为它贡献了 AutoRoute 自动路由增强：改它的 Rust 代理层，按规则自动选路，并打包分发给真实用户使用。它代表的是我"能读懂并改造成熟开源底层"的工程深度，而不只是从零写玩具。I contributed AutoRoute: an enhancement to its Rust proxy layer that picks routes by rule, packaged and shipped to real users. It shows depth — reading and reshaping a mature open-source core, not just building toys from scratch.
