权限Permission
Permission
解决什么问题What problem it solves
决定这个工具能碰你的哪些东西：读文件、改代码、发请求、花钱。The set of operations a tool is allowed to perform. Wider is more convenient and more dangerous.
这是什么What it is
指一个工具被允许做的操作范围。范围越大越方便，也越容易出事。
好的工具会分级授权：读要批准、写要批准、删要二次确认。
The permitted action scope of a tool. A wider scope is easier to use and easier to get into trouble with.
Good tools authorise in tiers: reading needs approval, writing needs approval, deleting needs confirmation.
为什么需要知道Why it matters
这是AI 工具安全的第一道闸门。给一个能写文件和跑命令的工具不给权限限制，等于把电脑交出去。It is the first gate on AI tool safety. Giving a tool that writes files and runs commands no permission limits is handing over the machine.
