# Codex Plugin-Dev:Skill 結構慣例
## 建議目錄結構
每個 skill 一個資料夾(與現有 `.codex/skills/*` 一致):
```
<CODEX_HOME>/skills/
my-skill/
SKILL.md
scripts/ # 可選:可重用腳本
templates/ # 可選:檔案模板
reference/ # 可選:重型參考文件(100+ 行)
```
## SKILL.md 必要元素(最低限度)
- YAML frontmatter
- `name`: 僅允許 `a-z0-9-`(全小寫 + hyphen)
- `description`: **以 "Use when..." 開頭**,只寫「什麼情況要用」,不要寫流程
- 內容要包含:
- Overview(這個 skill 的核心價值)
- When to use(用症狀/關鍵字讓搜尋命中)
- Quick start(最短可跑的指令或步驟)
## 觸發(Discovery)設計要點
`description` 盡量包含:
- 使用者會打的詞:`skill`, `SKILL.md`, `frontmatter`, `trigger`, `description`, `YAML`
- 症狀:`skill 沒觸發`, `找不到 skill`, `不會自動選用`
- 同義詞:`template`, `skeleton`, `boilerplate`, `scaffold`
## Supporting files 原則
- 「可複用工具」放 supporting file(script/template),避免把整段工具塞進 SKILL.md。
- 需要跑 Python 時:必須遵守專案 `uv + .venv`,且指令要用 `.venv\\Scripts\\python.exe`。
