在莫比乌斯 AI 中开发一个新拓展插件 (特殊应用). An agent skill from mobius-system/mobius.

  • Works in 4 steps: 后端 → 前端 → 规范 → …
  • SKILL.md covers 1. 后端, 2. 前端, 3. 规范 and 4. 主项目联合修改
  • Calls curl, npm and node; needs JWT_SECRET

What it does

Mobius Extension is an agent skill from mobius-system/mobius. 在莫比乌斯 AI 中开发一个新拓展插件 (特殊应用). 含后端 handler 协议、前端 SDK / 编译策略、目录与命名规范。一旦用户选择了这个SKILL(当然,也不排除选错的可能性),你需要认真考虑如何把用户的需求做成 Mobius 拓展,而不是一个完全独立的项目。

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with npm. The repository describes itself as: Self-Evolving Multi-Agent Operation System.

Example prompts

  • “/mobius-extension”

Requirements

  • Python 3
  • Node.js
  • A credential in JWT_SECRET

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. 后端
  2. 前端
  3. 规范
  4. 主项目联合修改

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:

    • curl
    • npm
    • node
    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use curl and npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • JWT_SECRET

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Mobius Extension loads about 1.3k tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 269 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:117
    # find $MOBIUS_PORT in `env var` or `.env` or `.env.default`, default 33314

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 269 words (~1,336 tokens).

“拓展 = mobius/extension// 一个目录. 新 tab 打开 /extension// 运行, 后端走 /api/ext 转发, 数据落到 APP_DIR/protected_data/extension//. 样例: mobius/extension/pacman/.”
