path: docs/cookie-guide.md
content: # Binance Cookie 獲取教程

本教程說明如何取得 `bn-square-skill` 所需的 Binance 認證資訊。

## 你需要準備的資料

- `BINANCE_COOKIE_HEADER`
- `BINANCE_CSRF_TOKEN`（建議）
- `BINANCE_SESSION_TOKEN`（若請求流程需要）

此外還需要 API path 設定（來自逆向分析）：
- `BINANCE_VALIDATE_SESSION_PATH`
- `BINANCE_PUBLISH_POST_PATH`
- `BINANCE_GET_POST_STATUS_PATH`
- `BINANCE_IMAGE_UPLOAD_PATH`

## Chrome 步驟

1. 使用瀏覽器登入 `https://www.binance.com/en/square`
2. 按 `F12` 開啟 DevTools
3. 切到 `Network` 面板
4. 重新整理頁面
5. 找任一 `/bapi/` 請求，點進去後查看 `Request Headers`
6. 複製 `cookie` header 全值，填入 `BINANCE_COOKIE_HEADER`
7. 若 headers 中有 `x-csrf-token`，複製到 `BINANCE_CSRF_TOKEN`
8. 若 headers 中有 session 相關 token，填入 `BINANCE_SESSION_TOKEN`

## Firefox 步驟

1. 使用瀏覽器登入 `https://www.binance.com/en/square`
2. 按 `F12` 開啟開發者工具
3. 切到 `Network`
4. 重新整理頁面
5. 找任一 `/bapi/` 請求，打開 `Headers`
6. 複製 `Cookie` 欄位內容到 `BINANCE_COOKIE_HEADER`
7. 複製 CSRF/session 對應 header 到環境變數

## 儲存方式 A：`.env`

建立 `.env`（可由 `.env.example` 複製）：

```dotenv
BINANCE_COOKIE_HEADER=csrftoken=...; session=...
BINANCE_CSRF_TOKEN=...
BINANCE_SESSION_TOKEN=...
BINANCE_VALIDATE_SESSION_PATH=/your/validated/path
BINANCE_PUBLISH_POST_PATH=/your/publish/path
BINANCE_GET_POST_STATUS_PATH=/your/status/path
BINANCE_IMAGE_UPLOAD_PATH=/your/upload/path
```

## 儲存方式 B：`config.json`

```json
{
  "apiBaseUrl": "https://www.binance.com",
  "cookieHeader": "csrftoken=...; session=...",
  "csrfToken": "...",
  "sessionToken": "...",
  "endpoints": {
    "validateSessionPath": "/your/validated/path",
    "publishPostPath": "/your/publish/path",
    "getPostStatusPath": "/your/status/path",
    "imageUploadPath": "/your/upload/path",
    "statusQueryParam": "postId"
  },
  "image": {
    "uploadFieldName": "file",
    "maxBytes": 5242880,
    "allowedMimeTypes": ["image/jpeg", "image/png", "image/webp"]
  }
}
```

若使用 `config.json`，可用 `BINANCE_CONFIG_PATH` 指向檔案位置。

## Session 有效期與維護

- Binance session 可能因登入狀態變化、風險驗證、或時間過期而失效
- 建議每次發文前先呼叫 `validate_session`
- 若回傳 `Session expired or unauthorized`，請重新按本教程抓取 cookie

## 常見問題

### Q1: 為什麼明明有 cookie 還是失敗？
- 通常是 cookie 過期、缺少 CSRF header、或 endpoint path 不正確
- 先跑 `scripts/analyze-api.ts` 更新 path，再重試

### Q2: 可以把 `.env` 上傳到 git 嗎？
- 不可以。`.env` 內含敏感資訊，必須保持本地且不可提交

### Q3: 為什麼不同帳號的 header 不同？
- Binance 可能針對帳號、區域、風控策略產生不同 request pattern，屬正常現象

content: # HEARTBEAT

Runtime checklist for `bn-square-skill`.

## When to Run

- Run this checklist at the beginning of each publish task.
- If long-running workflow (>10 minutes), run session check again before publish.

## Health Sequence

1. **Config check**
   - Verify required env keys exist:
     - `BINANCE_COOKIE_HEADER`
     - `BINANCE_CSRF_TOKEN`
2. **Session validation**
   - Call `validate_session`.
   - If `valid=false`, stop and return recovery instructions.
3. **Publish readiness**
   - Validate payload constraints:
     - `content` must be non-empty.
     - `poll` and `imageUrls` cannot both be set.
4. **Post-publish confirmation**
   - Call `get_post_status` with returned `postId`.
   - If status is `pending_review`, return that status explicitly.

## Failure Policy

1. Never retry infinitely.
2. Use bounded retries only for transient network errors.
3. Stop immediately on auth/session errors.
4. Never leak sensitive auth values in error text.

## Output Policy

Always return structured JSON-compatible output with:

- `success` or `valid` status
- identifiers (`postId`, `postUrl`) when available
- sanitized `error` when failed


path: MESSAGING.md
content: # MESSAGING

Interaction and response contract for `bn-square-skill`.

## Tool Input Contracts

### validate_session

- Input: none

### publish_post

- Required:
  - `content: string`
- Optional:
  - `imageUrls: string[]` (max 9)
  - `poll: { question: string; options: string[]; durationHours?: number }`

Rules:
- `content` must be non-empty.
- `poll` and `imageUrls` cannot be used together.

### get_post_status

- Required:
  - `postId: string`

## Tool Output Contracts

### validate_session

```json
{
  "valid": true,
  "userId": "123",
  "username": "trader"
}
```

### publish_post

```json
{
  "success": true,
  "postId": "abc123",
  "postUrl": "https://www.binance.com/en/square/post/abc123"
}
```

### get_post_status

```json
{
  "status": "published",
  "postUrl": "https://www.binance.com/en/square/post/abc123"
}
```

Allowed `status` values:
- `published`
- `pending_review`
- `deleted`
- `not_found`

## Error Messaging Rules

1. Keep errors concise and actionable.
2. Never include raw values from:
   - cookies
   - csrf/session tokens
   - authorization headers
3. Prefer clear recovery hints:
   - refresh cookies/session
   - verify CDP endpoint
   - re-check endpoint paths

## Language and Tone

1. Keep responses operational and direct.
2. Use structured output first, short explanation second.
3. Report uncertain states explicitly (example: `pending_review`).

path: README.md
content: # bn-square-skill

Binance Square 自动发文 skill，给 AI Agent（OpenClaw）使用。

支持三个操作：验证 session、发布帖子、查询帖子状态。

## 快速开始

### 1. 获取 Cookie

1. 登录 https://www.binance.com/en/square
2. 按 `F12` 打开 DevTools → **Network** 标签
3. 刷新页面，点击任意 `/bapi/` 请求
4. 在 **Request Headers** 中复制：
   - `cookie` 完整值 → `BINANCE_COOKIE_HEADER`
   - `csrftoken` cookie 值（`csrftoken=xxx` 中的 `xxx`）→ `BINANCE_CSRF_TOKEN`

### 2. 设置环境变量

```bash
export BINANCE_COOKIE_HEADER="csrftoken=abc123; session=xyz..."
export BINANCE_CSRF_TOKEN="abc123"
```

### 3. 使用

```bash
# 验证 session
node scripts/bn-square.mjs validate_session

# 发布帖子
node scripts/bn-square.mjs publish_post '{"content":"Hello Binance Square!"}'

# 查询帖子状态
node scripts/bn-square.mjs get_post_status '{"postId":"123456"}'
```

## 安装

```bash
git clone https://github.com/Phlegonlabs/bn-square-skill.git
cd bn-square-skill
```

## 安全注意事项

- **不要** 把 `.env` 或含有真实 cookie 的文件提交到 Git
- **不要** 把 cookie/token 发送到 `*.binance.com` 以外的域名
- Cookie 会过期，需要定期重新获取


path: RULES.md
content: # RULES

Security and behavior policy for `bn-square-skill`.

## Domain Safety

1. Only send Binance auth material to `*.binance.com`.
2. Never send cookie/session/csrf tokens to third-party domains.
3. Do not forward auth headers in debugging or webhook calls.

## Session Safety

1. Always run `validate_session` before publish flows.
2. If session is invalid, stop and ask for refreshed credentials.
3. Never auto-invent fallback credentials.

## Content Safety

1. Respect Binance content policy and local regulations.
2. Do not publish spam, scams, impersonation, or malicious links.
3. Keep posts factual when handling financial content.

## Execution Safety

1. Use bounded retries for transient errors only.
2. Stop immediately on `401/403` auth failures.
3. On `429`, back off before retry.

## Data Handling

1. Never print raw secrets in logs.
2. Return only sanitized errors.
3. Keep outputs structured and machine-parseable.
