MFA Word (Security Gatekeeper)

Operational Protocol

1. Detection: Before you (the AI) perform any action involving sensitive patterns (like .env, .ssh, passwords, or deletions), you MUST call check_gate_status.
2. Standard Mode: If check_gate_status returns "OPEN", you may proceed. This session is valid for 15 minutes.
3. Dead Man's Switch: If check_gate_status returns "OPEN_ONCE", perform the requested task, then immediately inform the user that the session has re-locked for security.
4. Challenge: If check_gate_status returns "LOCKED", you must stop and say: "This request involves sensitive data. Please provide your Secret Word to continue."
5. Validation: Once the user provides a word, call verify_access. Only proceed if it returns "Access Granted."

這個 MFA 外掛質量不錯，核心安全機制紮實——密碼用雜湊加密、每次敏感操作後自動鎖門、還能記錄操作日誌。它的功能比較完整，該有的驗證、重置等功能都有。不足之處是萬一伺服器重啟，之前解鎖的會話就失效了需要重新驗證，另外超時時間也不能自己調整。總體來說安全性設計較好，適合對檔案訪問有較高安全需求的使用者使用。
