Add this skill
Claude
Claude Code loads skills from ~/.claude/skills/ (all projects) or .claude/skills/ (one project):
git clone --depth 1 https://github.com/hAcKlyc/MyAgents.git
cp -r MyAgents/bundled-skills/tool-creator ~/.claude/skills/tool-creator # personal, or .claude/skills in a projectIn the Claude apps, zip the tool-creator folder and upload it under Customize > Skills > + > Upload a skill (code execution must be on).
ChatGPT / Codex
Codex reads skills from .agents/skills/ in a repo or ~/.agents/skills/ for every project:
git clone --depth 1 https://github.com/hAcKlyc/MyAgents.git
cp -r MyAgents/bundled-skills/tool-creator .agents/skills/tool-creator # repo; ~/.agents/skills for all projectsStandalone skills also load in the ChatGPT desktop app.
Cursor
Cursor loads skills from .cursor/skills/ (or ~/.cursor/skills/) and also reads .claude/skills/:
git clone --depth 1 https://github.com/hAcKlyc/MyAgents.git
cp -r MyAgents/bundled-skills/tool-creator .cursor/skills/tool-creator # project; ~/.cursor/skills for all projectsSource (checked Oct 7, 2026): code.claude.com/docs/en/skills (opens in a new tab), support.claude.com/en/articles/12512180-using-skills-in-claude (opens in a new tab), learn.chatgpt.com/docs/build-skills (opens in a new tab), cursor.com/docs/context/skills (opens in a new tab)
What this skill does
把用户的可复用需求封装成标准化的 Agent-CLI 工具，并用 myagents tool add 注册进 MyAgents 工具注册表——注册后所有未来会话（builtin / DSH / Claude Code / Codex 全 runtime）的 AI 都会在 system prompt 里自动发现它。触发场景：(1) 用户说「把 XX 封装成工具」「做成一个工具」「注册个工具」「写个 CLI」「以后能直接用」；(2) 用户描述一个会反复出现的自动化需求——文档/文件批量处理、调用某个云 API、用某个多模态大模型做图像/视频理解等，即使没说"工具"两个字；(3) 你发现自己第二次为同类需求写几乎一样的脚本——这时要主动提议把它升格为注册工具，不要等用户开口。反向边界：一次性任务就地解决、不铸工具；接入现成的 MCP server 用 myagents mcp，不归这里。 你正在 MyAgents 里运行。MyAgents 有一个工具注册表（~/.myagents/tools/）：注册进去的 CLI 工具会被投放到 PATH（~/.myagents/bin/），它的…
