Already coding with an AI agent? Dollar hooks in and watches what it's about to run — flagging risky commands on the spot, and asking first on the irreversible ones.已经在用 AI 助手编码了？叨乐接入后会盯着它将要执行的命令——当场标出有风险的部分，撤不回来的那类才先征求你的同意。

Honest limits: Dollar is a safety net, not a replacement for Git or backups — a gate that asks first, not a sandbox. While it's running, a high-risk action waiting on your decision is held rather than run. Quit Dollar and supervision stops entirely.诚实的边界：叨乐是一张安全网，而不是 Git 或备份的替代品——它是一道先问你一声的关卡，而非沙箱。只要它在运行，等着你决定的高风险操作会被拦下而不是被执行。退出叨乐，守护就完全停止。

Companion, safety supervision, and cost estimates are all part of Dollar.陪伴、安全监督与成本估算，都是叨乐的一部分。
