+# Browser CLI Unification Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 为抖音、快手、小红书三家浏览器平台统一 `sau` CLI 契约，补齐小红书 CLI/skill，并把视频正文统一为 `desc`、图文正文统一为 `note`。
+
+**Architecture:** 保持现有 `sau_cli.py` 单文件主入口，不引入新的 CLI 框架。`sau_cli.py` 负责 parser、request dataclass、dispatch 和账号文件解析；各平台 uploader 只做最小字段接线；skill、README、CLI/install/update 文档、examples 同步切到统一契约，避免对外同时暴露多套命名。
+
+**Tech Stack:** Python 3.10+, `argparse`, `asyncio`, `dataclasses`, `pathlib`, `unittest`, existing Patchright-based uploaders, repository markdown docs

+## Task 1: 用测试锁定统一 CLI 契约
+
+**Files:**
+- Create: `tests/test_sau_browser_cli.py`
+- Reference: `sau_cli.py`
+
+- [ ] **Step 1: 写统一 CLI parser 测试**
+
+在 `tests/test_sau_browser_cli.py` 里覆盖最小命令契约：
+
+```python
+import asyncio
+import unittest
+from argparse import Namespace
+from pathlib import Path
+from unittest.mock import AsyncMock, patch
+
+import sau_cli
+
+
+class BrowserCliParserTests(unittest.TestCase):
+    def test_build_parser_accepts_xiaohongshu_login(self):
+        parser = sau_cli.build_parser()
+        args = parser.parse_args(["xiaohongshu", "login", "--account", "creator"])
+        self.assertEqual(args.platform, "xiaohongshu")
+        self.assertEqual(args.action, "login")
+
+    def test_douyin_upload_video_accepts_desc(self):
+        parser = sau_cli.build_parser()
+        args = parser.parse_args([
+            "douyin", "upload-video",
+            "--account", "creator",
+            "--file", "demo.mp4",
+            "--title", "标题",
+            "--desc", "视频简介",
+        ])
+        self.assertEqual(args.desc, "视频简介")
+
+    def test_kuaishou_upload_note_accepts_title_and_note(self):
+        parser = sau_cli.build_parser()
+        args = parser.parse_args([
+            "kuaishou", "upload-note",
+            "--account", "creator",
+            "--images", "1.png",
+            "--title", "图文标题",
+            "--note", "图文正文",
+        ])
+        self.assertEqual(args.title, "图文标题")
+        self.assertEqual(args.note, "图文正文")
+```
+
+- [ ] **Step 2: 写 dispatch 路由测试**
+
+继续在 `tests/test_sau_browser_cli.py` 中补最小 dispatch 验证：
+
+```python
+class BrowserCliDispatchTests(unittest.TestCase):
+    def test_dispatch_xiaohongshu_check_prints_valid(self):
+        args = Namespace(platform="xiaohongshu", action="check", account="creator")
+        with patch("sau_cli.check_xiaohongshu_account", new=AsyncMock(return_value=True)):
+            code = asyncio.run(sau_cli.dispatch(args))
+        self.assertEqual(code, 0)
+
+    def test_dispatch_douyin_upload_note_uses_new_request_fields(self):
+        args = Namespace(
+            platform="douyin",
+            action="upload-note",
+            account="creator",
+            images=[Path("1.png")],
+            title="图文标题",
+            note="图文正文",
+            tags="测试,图文",
+            schedule=0,
+            debug=False,
+            headless=True,
+        )
+        with patch("sau_cli.upload_note", new=AsyncMock()) as mock_upload:
+            asyncio.run(sau_cli.dispatch(args))
+        request = mock_upload.await_args.args[0]
+        self.assertEqual(request.title, "图文标题")
+        self.assertEqual(request.note, "图文正文")
+```
+
+- [ ] **Step 3: 先跑测试确认失败**
+
+Run:
+
+```powershell
+py -3 -m unittest tests.test_sau_browser_cli -v
+```
+
+Expected:
+
+- 因为 `sau_cli.py` 还没有 `xiaohongshu` 分支和统一字段而失败
+
+- [ ] **Step 4: 提交测试脚手架**
+
+```powershell
+git add tests/test_sau_browser_cli.py
+git commit -m "test: define browser cli unification contract"
+```
+
+## Task 2: 改 `sau_cli.py`，补齐统一参数与小红书路由
+
+**Files:**
+- Modify: `sau_cli.py`
+- Reference: `uploader/xiaohongshu_uploader/main.py`
+- Reference: `uploader/douyin_uploader/main.py`
+- Reference: `uploader/ks_uploader/main.py`
+
+- [ ] **Step 1: 增加小红书 request dataclass**
+
+在 `sau_cli.py` 中新增：
+
+```python
+@dataclass(slots=True)
+class XiaohongshuVideoUploadRequest:
+    account_name: str
+    video_file: Path
+    title: str
+    description: str
+    tags: list[str]
+    publish_date: datetime | int
+    thumbnail_file: Path | None = None
+    publish_strategy: str = XIAOHONGSHU_PUBLISH_STRATEGY_IMMEDIATE
+    debug: bool = True
+    headless: bool = True
+
+
+@dataclass(slots=True)
+class XiaohongshuNoteUploadRequest:
+    account_name: str
+    image_files: list[Path]
+    title: str
+    note: str
+    tags: list[str]
+    publish_date: datetime | int
+    publish_strategy: str = XIAOHONGSHU_PUBLISH_STRATEGY_IMMEDIATE
+    debug: bool = True
+    headless: bool = True
+```
+
+- [ ] **Step 2: 改造抖音、快手 request dataclass**
+
+把字段统一到以下模型：
+
+```python
+class DouyinVideoUploadRequest:
+    title: str
+    description: str
+
+class DouyinNoteUploadRequest:
+    title: str
+    note: str
+
+class KuaishouVideoUploadRequest:
+    title: str
+    description: str
+
+class KuaishouNoteUploadRequest:
+    title: str
+    note: str
+```
+
+要求：
+
+- 视频用 `description`
+- 图文用 `note`
+- 不再把图文 request 设计成只有历史 `note` 语义但没有 `title`
+
+- [ ] **Step 3: 改 parser**
+
+在 `build_parser()` 里完成：
+
+- `douyin upload-video` 增加 `--desc`
+- `kuaishou upload-video` 增加 `--desc`
+- `douyin upload-note` 改成 `--title --note`
+- `kuaishou upload-note` 改成 `--title --note`
+- 新增整套 `xiaohongshu`：
+  - `login`
+  - `check`
+  - `upload-video --title --desc --tags --thumbnail`
+  - `upload-note --images --title --note --tags`
+
+- [ ] **Step 4: 补小红书账号操作函数**
+
+在 `sau_cli.py` 中新增：
+
+```python
+async def login_xiaohongshu_account(account_name: str, headless: bool = True) -> dict: ...
+async def check_xiaohongshu_account(account_name: str) -> bool: ...
+async def upload_xiaohongshu_video(request: XiaohongshuVideoUploadRequest) -> Path: ...
+async def upload_xiaohongshu_note(request: XiaohongshuNoteUploadRequest) -> Path: ...
+```
+
+要求：
+
+- 账号路径继续走 `resolve_account_file("xiaohongshu", account_name)`
+- 登录 / 检查分别复用 `xiaohongshu_setup` 与 `cookie_auth`
+- 上传前先做 `setup(handle=False)` 校验
+
+- [ ] **Step 5: 改 dispatch**
+
+要求：
+
+- 三家浏览器平台都统一输出：
+  - `login` 成功时打印账号文件路径
+  - `check` 输出 `valid` / `invalid`
+  - `upload-video` 打印简洁摘要
+  - `upload-note` 打印图片数量摘要
+- request 构造统一映射：
+  - 视频：`title + description`
+  - 图文：`title + note`
+
+- [ ] **Step 6: 跑 CLI 测试确认通过**
+
+Run:
+
+```powershell
+py -3 -m unittest tests.test_sau_browser_cli -v
+```
+
+Expected:
+
+- `BrowserCliParserTests`
+- `BrowserCliDispatchTests`
+
+全部通过
+
+- [ ] **Step 7: 跑最小 help 自检**
+
+Run:
+
+```powershell
+py -3 sau_cli.py douyin --help
+py -3 sau_cli.py kuaishou --help
+py -3 sau_cli.py xiaohongshu --help
+py -3 sau_cli.py xiaohongshu upload-note --help
+```
+
+Expected:
+
+- 小红书子命令存在
+- 图文命令展示 `--title`、`--note`
+- 视频命令展示 `--desc`
+
+- [ ] **Step 8: 提交 CLI 主线**
+
+```powershell
+git add sau_cli.py tests/test_sau_browser_cli.py
+git commit -m "feat: unify browser cli contracts"
+```
+
+## Task 3: 给 uploader 做最小字段接线
+
+**Files:**
+- Modify: `uploader/douyin_uploader/main.py`
+- Modify: `uploader/ks_uploader/main.py`
+- Modify: `uploader/xiaohongshu_uploader/main.py`
+- Modify: `tests/test_xiaohongshu_uploader.py`
+
+- [ ] **Step 1: 给抖音视频接入 `desc`**
+
+在 `DouYinVideo.__init__()` 中补 `desc` 参数和 `self.desc`，并把发布页填写逻辑改成：
+
+```python
+await self.fill_title_and_description(page, self.title, self.desc or self.title, self.tags)
+```
+
+- [ ] **Step 2: 给抖音图文接入 `title + note`**
+
+在 `DouYinNote.__init__()` 中补 `title` 参数，保留 `note` 作为图文正文，发布页填写改成：
+
+```python
+await self.fill_title_and_description(page, self.title, self.note, self.tags)
+```
+
+要求：
+
+- `title` 必填
+- `note` 可选但建议非空；如果现有逻辑要求非空，就继续保留校验
+
+- [ ] **Step 3: 给快手视频接入 `desc`**
+
+在 `KSVideo.__init__()` 中补 `desc` 参数和 `self.desc`，填写“描述”区域时改成：
+
+```python
+await page.keyboard.type(self.desc or self.title)
+```
+
+- [ ] **Step 4: 给快手图文接入 `title + note`**
+
+在 `KSNote.__init__()` 中补 `title` 参数与 `self.title`，保留 `self.note` 作为正文。
+
+要求：
+
+- 图文上传校验里增加 `title` 必填
+- 如果页面当前只有正文输入区，没有独立标题区，仍然要在 CLI / request / 构造函数层保持 `title` 字段，以便后续平台对齐
+
+- [ ] **Step 5: 检查小红书 CLI 接线是否需要补充适配**
+
+确认 `XiaoHongShuVideo` / `XiaoHongShuNote` 只需要以下映射即可：
+
+```python
+title=request.title
+desc=request.description  # 视频
+desc=request.note         # 图文
+```
+
+如果 `XiaoHongShuNote` 里还保留历史 `note` 兼容，不要删，只保持 CLI 层优先走 `title + note + tags`。
+
+- [ ] **Step 6: 补一条小红书映射测试**
+
+在 `tests/test_xiaohongshu_uploader.py` 中增加最小断言：
+
+```python
+def test_note_title_defaults_do_not_override_explicit_title(self):
+    app = xhs_main.XiaoHongShuNote(
+        image_paths=["a.png"],
+        note="正文",
+        tags=[],
+        publish_date=0,
+        account_file="account.json",
+        title="显式标题",
+        desc="图文正文",
+    )
+    self.assertEqual(app.title, "显式标题")
+    self.assertEqual(app.desc, "图文正文")
+```
+
+- [ ] **Step 7: 跑 uploader 相关测试**
+
+Run:
+
+```powershell
+py -3 -m unittest tests.test_xiaohongshu_uploader -v
+```
+
+Expected:
+
+- 小红书 uploader 相关单测通过
+
+- [ ] **Step 8: 提交 uploader 接线**
+
+```powershell
+git add uploader/douyin_uploader/main.py uploader/ks_uploader/main.py uploader/xiaohongshu_uploader/main.py tests/test_xiaohongshu_uploader.py
+git commit -m "feat: align browser uploader metadata fields"
+```
+
+## Task 4: 新增小红书 skill，并同步更新抖音、快手 skill

+- Modify: `skills/kuaishou-upload/scripts/examples/kuaishou_commands.sh`
+- Modify: `skills/kuaishou-upload/scripts/examples/kuaishou_cli_template.py`
+
+- [ ] **Step 1: 复制现有 skill 目录结构作为小红书骨架**
+
+要求：
+
+- 风格对齐 `skills/douyin-upload/`
+- 默认优先走 `sau xiaohongshu ...`
+- 明确小红书支持：
+  - `login`

+  - `upload-video`
+  - `upload-note`
+
+- [ ] **Step 2: 写小红书 CLI 契约**
+
+至少写清：

+sau xiaohongshu check --account <account>
+sau xiaohongshu upload-video --account <account> --file <video> --title "<title>" [--desc "..."] [--tags ...]
+sau xiaohongshu upload-note --account <account> --images <img...> --title "<title>" [--note "..."] [--tags ...]
+```
+
+- [ ] **Step 3: 更新抖音、快手 skill 契约**
+
+要求：
+
+- 视频示例命令补 `--desc`
+- 图文示例命令改成 `--title --note`
+- 所有模板文件同步更新，不要只改文档不改脚本
+
+- [ ] **Step 4: 做 skill 文件级自检**
+
+Run:
+
+```powershell
+Get-ChildItem skills\xiaohongshu-upload -Recurse
+Get-Content skills\douyin-upload\references\cli-contract.md
+Get-Content skills\kuaishou-upload\references\cli-contract.md
+```
+
+Expected:
+
+- 小红书 skill 目录完整
+- 抖音、快手 skill 契约都已经切到新参数模型
+
+- [ ] **Step 5: 提交 skill 变更**
+
+```powershell
+git add skills/xiaohongshu-upload skills/douyin-upload skills/kuaishou-upload
+git commit -m "feat: add xiaohongshu skill and align browser skill contracts"
+```
+
+## Task 5: 更新 examples 和 README / docs

+- Modify: `docs/update.md`
+
+- [ ] **Step 1: 改小红书 examples**
+
+要求：
+
+- `examples/get_xiaohongshu_cookie.py` 明确指向 `sau xiaohongshu login --account <account_name>` 这一主线
+- `examples/upload_video_to_xiaohongshu.py` 说明当前主线优先走 CLI
+- 如果继续保留 uploader 直连示例，注释里标明“调试入口 / 历史直连路径”
+
+- [ ] **Step 2: 更新 README 平台表和快速开始**
+
+README 至少要改这些位置：
+
+- 平台能力表里把小红书改成：
+  - `CLI ✅`
+  - `Skill ✅`
+- 快速开始里的浏览器平台命令改成统一契约
+- 抖音、快手图文示例改成：

+sau xiaohongshu upload-note --account <account_name> --images videos/1.png videos/2.png --title "图文标题" --note "图文正文"
+```
+
+- [ ] **Step 3: 更新 `docs/CLI.md`**
+
+要求：

+```
+
+Expected:
+
+- README、CLI、install、update 都出现小红书 CLI
+- 图文正文写成 `--note`
+- 视频描述写成 `--desc`
+
+- [ ] **Step 6: 跑最终最小验证**
+
+Run:
