That is the question my projects keep circling, from different directions. It looks like a question about capability, and the usual answer is a bigger model, more tools, a longer context window. I do not think that is the hard part. 这是我的几个项目从不同方向反复绕着的问题。它看起来像是能力问题，常见的答案是更大的模型、更多工具、更长的上下文。我认为难的不在那里。
A partner is defined by what it remembers, what it is allowed to do without asking, and whether it is still there when the network is not. Those are design decisions, and they get made by whoever builds the thing around the model. 一个伙伴由三件事定义：它记得什么、什么事可以不问就做、断网之后它还在不在。这些是设计决定，由在模型外面搭东西的人做出。
What I have committed to so far目前为止我押的注
Each of these is a position, not a claim about results. What follows each one is the thing in the code that pays for it. 每一条都是立场，不是对结果的断言。每条后面跟着代码里为它付出的代价。
It should run where you are, not where I am.它应该跑在你那里，不是跑在我这里。
If a companion holds your messages and your files, the honest place for it is your own machine. Convenience is the argument for the other design, and it is a real argument. I would rather pay the convenience cost. 如果一个伙伴握着你的消息和文件，它诚实的位置是你自己的机器。另一种设计的理由是方便，那是个真实的理由。我宁可付这个方便的代价。
CC is a daemon on your computer. Its working files and memory live on your disk. Model providers and mobile connections may use network services. Your computer has to be awake for CC to answer. CC 是跑在你电脑上的守护进程。工作文件和记忆留在本机磁盘；模型调用和手机连接可能使用网络服务。你的电脑必须开着，CC 才能回话。
It should ask before it acts.动手之前先问。
An agent that can edit files is not a chat window, and should not feel like one at the moment it matters. The pause where it asks is the whole difference between a tool you are using and a tool that is using your machine. 一个能改文件的 Agent 不是聊天窗口，在关键时刻也不该像聊天窗口。它停下来问你的那一刻，正是「你在用工具」和「工具在用你的机器」之间的全部区别。
CC uses permission cards for actions that require approval. The point is to make the action and its boundary visible, without turning every ordinary step into another question. CC 用授权卡片呈现需要批准的操作。我关心的是把动作和边界说清楚，同时让已经授权的日常工作顺畅地继续。
It has to be held to what it said.它得为自己说过的话负责。
Generating more text is easy. Staying consistent with what was already generated is the part that breaks, and it breaks quietly. So the state has to live outside the model, in something a person can read. 生成更多文字很容易。和已经生成的东西保持一致才是会坏的那部分，而且坏得很安静。所以状态必须活在模型之外，活在人能读懂的东西里。
Nate & Cynthia keeps a ledger of what the story promised and what contradicts what. hearth proposes changes as reviewable plans over plain markdown you can still read if my software disappears. Nate & Cynthia 维护一张账本，记故事承诺过什么、哪里自相矛盾。hearth 把改动写成可审阅的计划，底下是纯 Markdown，我的软件消失了你依然读得懂。
Understanding comes before advice.先理解，再建议。
Most software that reads your health data moves straight to telling you what to do. I want to see whether a product can earn the right to say anything by first showing it understood the day. 大多数读你健康数据的软件会直接跳到告诉你该做什么。我想看看一个产品能不能先证明自己读懂了这一天，再换取说话的资格。
melu is the attempt: a Flutter app for iOS and Android, with photo, voice and text entries, gentle responses and weekly reflection. Its iOS version has been on the App Store since October 2026. Whether it helps people understand their days still needs to be learned through use. melu 是这个尝试：用 Flutter 做的 iOS 和 Android 应用，已有拍照、语音和文字记录、温和回应与周回顾，iOS 版 2026 年 10 月已上架 App Store。它能否帮助人理解自己的日常，仍要从实际使用中学习。
Leave room for an ordinary day.给普通的一天留一点位置。
A day outside does not have to be a trip worth announcing. A few photos, a route, a small detail can be enough to want to keep it.出门不一定是一场值得宣布的旅行。几张照片、一段路、一个小细节，就足够让人想留住这一天。
ranu turns an outing into a hand-drawn map and journal page, with stamps and sharing. It is in TestFlight, open to friends and family. The next question is how it feels with someone’s real photo library.ranu 把一次出门整理成手绘地图和手帐，带着集章与分享。现在通过 TestFlight 给亲友试用，接下来要看它在真实相册里用起来怎样。
What would change my mind什么会让我改变想法
If people turn the permission step off the first week, then asking before acting is my preference rather than a requirement, and I should stop calling it a principle. 如果人们第一周就把授权关掉，那么「动手前先问」只是我的偏好而不是必需，我就该停止把它叫做原则。
If local models never get good enough for the ordinary cases, then running on your own machine is a hobbyist position, not a product one. 如果本地模型始终不足以应付普通场景，那么「跑在你自己机器上」就是爱好者的立场，不是产品的立场。
And if the companionship turns out to be something people tolerate rather than want, then CC is a good remote control wearing a costume, and I should take the costume off. 还有，如果陪伴这件事最后只是被人忍受而不是被人想要，那 CC 就是一个穿着戏服的好用遥控器，我应该把戏服脱掉。
I write down what these look like in practice as I go. Writing. Or tell me where I am wrong. 实践中的样子我边做边记。Writing。 或者告诉我哪里错了。
