A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

分析本週花費並產出下週預算參考,寫入 config 指定的本地資料夾。
/weekly-budget-report
路徑:.claude/skills/weekly-budget-report/config.json
執行 0.5 的偵測(bean file、currency、budgets.bean),先一次顯示偵測結果:
🔍 偵測中...
✓ Bean file: ./main.bean
✓ Currency: TWD
✓ Found budgets.bean → N monthly categories, M yearly categories
(或:未找到 budgets.bean → 將用所有頂層 Expenses 類別)接著逐一詢問三個問題,每問完一題等使用者回答後再問下一題(不要一次列出 3 題):
Q1: 請輸入週報輸出路徑(本地資料夾或 Obsidian vault 內子目錄)[預設 ./docs/reports/]:
→ 等使用者回答後再問 Q2
Q2: 月度總預算 [預設 X,monthly 類別加總]:
→ 等使用者回答後再問 Q3
Q3: 年度總預算 [預設 Y,yearly 類別加總]:
→ 收齊後進入 0c
預設值規則:
output_path:預設 = {當前目錄}/docs/reports/。空白 Enter 用預設。monthly_budget_total:預設 = budgets.bean 中 "monthly" entries 加總。沒 budgets.bean 時無預設、必填。yearly_budget_total:預設 = budgets.bean 中 "yearly" entries 加總。沒 budgets.bean 時無預設、必填。收齊使用者輸入後:
output_path 目錄不存在,用 Bash mkdir -p 建立.claude/skills/weekly-budget-report/config.json:(若使用者輸入相對路徑,先用 realpath 或 cd ... && pwd 展開為絕對路徑再寫入)
{
"output_path": "/expanded/absolute/path",
"monthly_budget_total": 30000,
"yearly_budget_total": 120000
}✓ 寫入 config.json,繼續下一步不快取於 config,每次都即時推導。

fi讀取 bean file,搜尋:option "operating_currency" "XXX"
grep '^option "operating_currency"' <bean_file> | head -1抽出引號內貨幣代碼:
currency=$(grep '^option "operating_currency"' <bean_file> | sed 's/.*"\([^"]*\)".*/\1/')找不到時 fallback 詢問使用者。
檢查專案根目錄是否有 budgets.bean 或 budget.bean。

{
"name": "Food", # account 末段
"pattern": "^Expenses:Food", # 用於 bean-query regex

}執行:
