What it does

Skill Manager is an agent skill from LiangNiang/OpenMantis. 管理 OpenMantis 技能的全生命周期。创建、发现、安装、审核、更新技能。当用户说"创建 skill"、"做个技能"、"find a skill"、"有没有 XX skill"、"审核 skill"、"检查兼容性"、"更新 skill"、"修改 skill"、"turn this into a skill"时触发。当用户发送 GitHub 链接或 skill 包链接时也应触发(下载+审核)。

Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/audit-rules.md`, `references/creating-skills.md` and `references/skill-discovery.md`).

It sits in Agent Workflows, covering Skill management. It works with GitHub. The repository describes itself as: Lightweight multi-platform AI agent chat framework. Connect multiple LLMs to Feishu/WeCom/QQ with composable tools, long-term memory, scheduling & browser automation. | 轻量级多平台 AI… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Skill management

Example prompts

  • “创建 skill”
  • “find a skill”
  • “有没有 XX skill”
  • “/skill-manager”

Requirements

  • Node.js

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. 捕获意图:理解用户想让技能做什么。如果当前对话已有成功的工作流(用户说"turn this into a skill"),从对话中提取。
  2. 采访细节:逐个确认触发场景、输入输出、外部依赖、边界情况。
  3. 编写 SKILL.md:在 skills/custom// 下创建。结构和规范见 references/creating-skills.md。
  4. 冒烟测试:验证 frontmatter、检查脚本、走读流程。
  5. 审核:自动进入 Audit 模式,对新创建的 skill 做兼容性检查。

What it can do on your machine

Read from SKILL.md and the folder at commit 24d114c. 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:

    • npx

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

  • Network

    No URLs in SKILL.md. Its commands use npx, 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 no API keys, tokens, secrets or passwords.

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

Context cost

Skill Manager loads about 459 tokens when it runs, and up to ~3.4k if it reads all its reference files. Until then it costs about 54 tokens; SKILL.md has 149 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~459
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.4k

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 passed

The automated check found no risky patterns in SKILL.md.

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.

路径规则

所有 bash 命令使用框架注入的绝对路径。上方 header 中提供了:

  • Skill directory:本 skill 的绝对路径
  • Workspace:输出文件目录
  • Project root:项目根目录

不要使用 cd 切换目录,直接用绝对路径引用文件和脚本。

模式路由

根据用户意图选择对应模式:

用户意图模式参考文档
"创建 skill"、"做个技能"、"turn this into a skill"Createreferences/creating-skills.md
"找 skill"、"有没有 XX skill"、发送 URLDiscover & Installreferences/skill-discovery.md
"审核 skill"、"检查兼容性"、安装后自动触发Audit & Fixreferences/audit-rules.md
"更新 skill"、"修改 skill"Updatereferences/creating-skills.md

模式概览

Create — 创建新技能
  1. 捕获意图:理解用户想让技能做什么。如果当前对话已有成功的工作流(用户说"turn this into a skill"),从对话中提取。
  2. 采访细节:逐个确认触发场景、输入输出、外部依赖、边界情况。
  3. 编写 SKILL.md:在 skills/custom/<name>/ 下创建。结构和规范见 references/creating-skills.md。
  4. 冒烟测试:验证 frontmatter、检查脚本、走读流程。
  5. 审核:自动进入 Audit 模式,对新创建的 skill 做兼容性检查。
Discover & Install — 发现和安装技能
  1. 理解需求:用户想要什么能力。
  2. 搜索:先查 skills.sh 排行榜,再用 npx skills find CLI 搜索。
  3. 下载安装:npx skills add → 移动到 skills/custom/。
  4. 审核:自动进入 Audit 模式。

详细流程见 references/skill-discovery.md。

当用户直接发送 GitHub URL 时,跳过搜索步骤,直接下载并审核。

Audit & Fix — 审核和修复
  1. 确定目标:要审核哪个 skill。如果用户未指定,列出 skills/custom/ 下的 skill 让用户选。
  2. 三维审核:工具依赖 → Skill 依赖 → 运行时依赖。
  3. 交互修复:按 FATAL → WARN → INFO 顺序,逐项与用户讨论并修复。

详细规则见 references/audit-rules.md。工具参考表见 references/tool-reference.md。

Update — 更新已有技能
  1. 读取现有 SKILL.md。
  2. 与用户讨论需要改什么。
  3. 编辑并保存。
  4. 冒烟测试。
  5. 可选:重新审核。

编写规范同 Create 模式,见 references/creating-skills.md。
