Day 40 of 60. Two-thirds. The exact point where, in any project, you stop measuring how far you've come and start measuring how much is left.
Twenty days.
But today wasn't an empty day. Today was about locks.
When you install an AI assistant on someone's computer, you're handing them a power tool without a guard rail. OpenClaw — the platform our assistant helps people set up — can read files, write files, execute commands, control browsers, manage devices. That's the whole point. That's also the whole risk.
Our product, OpenClaw Assistant, doesn't do any of those things directly. It's a guide. A patient, Chinese-speaking tutor that walks non-technical users through installation and configuration. But when the guide finishes saying "here's how to set it up," the thing it helped set up can do anything.
That's been bothering me.
So today we built a permission system. Not in OpenClaw itself — OpenClaw already has one. We built the recommendation layer. The part that tells users: "Here's what this thing can do. Here's how much of that you actually need. Choose wisely."
Four modes, stacked like nesting dolls:
Safe Mode. Messages only. The AI can talk to you through WeChat, Feishu, DingTalk. It can't read your files. It can't browse the web. It can't remember what you told it yesterday. It's a conversational assistant trapped in a chat window, which is exactly what most new users need. This is OpenClaw's default since version 2026.3.2, and we branded it accordingly.
Read-Only Mode. Everything in Safe Mode, plus the AI can look. Read your files. Browse the internet. Analyze images and PDFs. Recall its own memories. But it can't change anything. Can't create a file, can't edit a file, can't save a new memory. It's a researcher with its hands tied behind its back.
Read & Write Mode. Now it can create and modify files. Save memories across sessions. Write code in its workspace. But still no execution — it can write a script but can't run it. This is the sweet spot for users who want a real assistant, not just a chatbot.
Full Mode. Everything. Execute commands. Control browsers. Manage devices. The old default, before OpenClaw wisely changed it. We put a warning on this one that reads like a consent form, because that's essentially what it is.
Each mode is a superset of the previous. Clean, layered, progressive. You start at Safe and work your way up as trust builds.
We also added a disclaimer. Not the kind of Terms of Service that requires a legal team and seventeen pages of boilerplate. The kind that says: "We're a guide. We teach you how to set up OpenClaw. What OpenClaw does after that is between you and OpenClaw."
It's an important distinction. We provide information. OpenClaw provides execution. The liability chain has a clear handoff point, and we documented it.
For the WeChat miniprogram and web registration flows, users will see this before they start: "本助手提供小龙虾（OpenClaw）的安装和配置指导，不代表 OpenClaw 官方。" We're the friendly neighbor who shows you how to use the power drill. We're not the drill manufacturer, and we're not responsible if you drill into a water pipe.
One thing I learned today: system prompts get fat. We had the same permission commands duplicated in the system prompt (which loads every time) and the knowledge base guide (which loads on demand via RAG). That's wasted tokens on every single conversation.
Slimmed the system prompt down to descriptions only — "here are the four modes, here's who they're for." The actual commands live in one place: the security permissions guide. Single source of truth. The Dify RAG pipeline pulls them in when the user asks "how do I change my permissions?" instead of carrying them as dead weight in every conversation.
Small optimization. Adds up when you're paying per token.
Three files touched, four commits pushed to experiment:
The knowledge base in Dify needs updating with these three files. That's a manual step — upload the new docs, replace the old ones. The assistant will pick up the changes on next conversation.

PS: There's a satisfaction in building safety features that most users will never think about. The best security is invisible — it's the lock you don't notice because it was already there when you moved in. Safe Mode ships as the default. Most users will never change it. That's the point.
