What it does
Mobius Write Guide is an agent skill from mobius-system/mobius. 制作 Mobius 图文使用教程（理解用户意图 → Playwright 截图 → 红色编号标注 → 上传图床 → 写 markdown → 改 mkdocs → 本地构建验证 → commit/push 的全流程）。当用户说"加教程 / 写教程 / 图文教程 / tutorial"或要求把某个功能做成带截图的指南时使用。含本机所有硬编码常量、安全红线（绝不能截到密钥）和踩过的坑。
Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering Browser testing. It works with Playwright. The repository describes itself as: Self-Evolving Multi-Agent Operation System.
When your agent uses it
- Tasks that involve Browser testing
Example prompts
- “加教程 / 写教程 / 图文教程 / tutorial”
- “/mobius-write-guide”
Requirements
- Python 3
- Node.js
- A credential in MOB_TOKEN
Workflow steps
8 steps, taken from the step headings in SKILL.md.
- 理解用户、规划
- Playwright 截图（原始 PNG + 元素矩形）
- PIL 标注（红色编号 + 描边 + 标签）
- 上传图床
- 写 markdown（双语）
- 改 mkdocs.yml + docs/index
- 本地构建验证（务必做，CI 跑的是 mkdocs build）
- commit + push
What it can do on your machine
Read from SKILL.md and the folder at commit 5fe32b1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
gitpython3nodecurlnpxpipcodex
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
public.agent-matrix.comserve.nutshellai.cn
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
MOB_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Mobius Write Guide loads about 3.6k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 770 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: warnings
The automated check found patterns that need a careful read before installing.
- WarningContains zero-width charactersSKILL.md:171
- 末尾可加一句 `> 小贴士：...` 收尾。`⟨U+200D⟩`（零宽字符）当空行分隔，沿用旧教程习惯。
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 770 words (~3,555 tokens).
“把一个 Mobius 功能做成带标记截图的双语图文教程，发布到 mkdocs 文档站（GitHub Pages）。本技能是 docs/tutorial/04~14 这一批教程的制作经验沉淀，所有命令、常量、坑都是实测过的，照做即可。”
