重度 Claude Code 用户的老问题：五小时用量墙说撞就撞，切号还得重新登录、丢掉正在跑的会话。 我做了一套工具解决它：clauth fork 负责在活跃会话底下无感热切换 + 无人值守自动轮换， ccsbar 负责在菜单栏里把每个账号的余量、预报和健康状况摆在明面上。这篇讲痛点、讲产品、讲它怎么解决。

I run several Claude accounts and kept hitting the 5-hour wall mid-session. Switching meant logging out. So I built a daemon that hot-swaps the active login under a running session — and the whole thing turned on one non-obvious fact about how macOS stores an auth token.
