Automates the process of setting up the first admin user or adding new admins via the bootstrap endpoint. Includes a Python script for easy execution.
Push to remote and wait for CI to pass. If CI fails, read logs, fix bugs, and re-push. Repeat until green.
Use when building or debugging LangGraph multi-agent systems - eval-first execution, task decomposition, model routing by complexity, and cost discipline
Use when AI agent modifies API routes or backend logic - catch systematic blind spots where the same model writes and reviews code
Use when making or recording significant architectural decisions - capture context, alternatives, and rationale as structured ADRs
Use when you have a written implementation plan to execute with review checkpoints between tasks

所有需要用戶認證的頁面都必須載入 Pi SDK！
<head> 中加入：<!-- Pi Network SDK (REQUIRED for Pi Browser authentication) -->
<script src="https://sdk.minepi.com/pi-sdk.js"></script>
| 頁面類型 | 需要載入 | 原因 |
|---|---|---|
主應用入口 (index.html) | ✅ 是 | 登入/認證 |
論壇頁面 (forum/*.html) | ✅ 是 | 發文/評論/支付 |
治理頁面 (governance/*.html) | ✅ 是 | PRO 會員功能 |
詐騙追蹤 (scam-tracker/*.html) | ✅ 是 | 提交報告 |
法律頁面 (legal/*.html) | ❌ 否 | 靜態內容，無需認證 |
// auth.js Line 39-54
const PiEnvironment = {
isSafeSdkContext() {
// 必須是 HTTPS 且非 localhost
return window.location.protocol === 'https:' && !this.isLocalhost();
},
hasPiSdk() {
// Pi SDK 必須已載入
return typeof window.Pi !== 'undefined' &&
typeof window.Pi.authenticate === 'function' &&
typeof window.Pi.init === 'function';
},
isPiBrowser() {
return this.isSafeSdkContext() && this.hasPiSdk();
}
};
| 問題 | 原因 | 解決方案 |
|---|---|---|
| 「請使用 Pi Browser」但已在 Pi Browser 中 | Pi SDK 未載入 | 確認 HTML 有 <script src="https://sdk.minepi.com/pi-sdk.js"></script> |
window.Pi is undefined | SDK script 未執行 | 檢查 CSP 是否允許 sdk.minepi.com |
| 認證後無反應 | SDK 載入但 Pi.init() 未呼叫 | 確認 auth.js 正確初始化 |
建立新 HTML 頁面時，確認：
</head> 之前window.Pi 存在
