About this skill

識別與避免 Claude Code agent 下 bash 指令的三層防線:(1) Anti-Pattern 1 過度複雜單行(多行 heredoc、巢狀引號、內嵌 Python -c / Node -e、複雜 if/elif、 for-loop-file-list),(2) Anti-Pattern 2 bash 字串內特殊 Unicode(em dash、 en dash、emoji),(3) Anti-Pattern 3 stateful cd(CWD 污染 / cd-before-git / cd + 2>/dev/null 路徑隱藏)。另含 Rule 14 shell 引號衛生(simpleexpansion / 同型引號衝突 / grep BRE alternation / 反向巢狀 subshell / expansion false positive)與 Rule 15 不可逆操作邊界(alembic migrate / terraform apply / git push --force / rm -rf / kubectl apply)。觸發情境:parser 錯誤「Unhandled node type: string」「Contains simpleexpansion」「Contains expansion」「Newline followed by inside quoted argument」、「bash heredoc 失敗」、「cd 會污染 CWD」、「stateful cd」、「不可逆操作要不要執行」、「terraform apply 確認」、「git push --force 安全嗎」、agent 自我反省「這段 bash 太複雜」「要不要寫成 script」「cd 指令要不要改成 --directory」時。
