-## InterviewTimer
+## 构建与验证
 
-`InterviewTimer` 是一个 macOS 面试悬浮计时 App。它用 JSON 模板描述电话面、编码面、系统设计面等不同流程，运行时显示当前环节剩余时间、整体剩余时间和提前/落后进度。
-
-源码位置：
-
-```bash
-mac_app/interview_timer
-```
-
-构建：
-
-```bash
-cd mac_app/interview_timer
-swift test
-swift build --product InterviewTimerApp
-./scripts/build_app.sh
-open dist/InterviewTimer.app
-```
-
-完整背景、模板格式、使用方式和安装方式见：[docs/interview_timer.md](docs/interview_timer.md)。
-
-## retry_exec
-
-一个简单的重试工具，可以套在 crontab 等地方，避免程序单次执行失败。
-
-![使用方法](https://mcoder-image-storage.oss-cn-hangzhou.aliyuncs.com/image/25261022_98943128e13fed75.jpg)
-
-这个程序有什么能力呢？
-1. 配置后使用简单，`retry_exec [your command] [your command args] [your command args] ...` 只要在你的命令执行前加上`retry_exec` 即可。
-2. 帮你重试，重试次数可以自定义；
-3. 重试时逐渐延长间隔时间，每次延长 2 倍，最小间隔时间、最大间隔时间可以自己设置；
-4. 如果程序最终执行失败，可以通过飞书自定义机器人、企业微信自定义机器人等渠道给自己发送一个提醒；
-5. 失败提醒会附带本次最终失败执行输出的末尾内容：优先取 `stderr`，如果 `stderr` 为空则取 `stdout`，最多 4KB，方便直接看到真实报错。

-
-
-**安装与配置**
-
-```bash
-./install.sh --tool retry_exec
-```
-
-脚本会安装 `retry_exec`，并在 `/etc/life_tools/retry_exec.json` 不存在时写入示例配置。日志目录按系统选择：Linux 使用 `/var/log/retry_exec`，macOS 使用 `~/Library/Logs/retry_exec`。安装后编辑配置里的提醒机器人地址和日志路径。

-## renameV1
-
-命令行批量重命名文件名的工具。我在家里有一台 NAS，安装了 emby，但每次下载动漫时，因为文件名命名不规范，导致 emby 无法识别，修改文件名过于繁琐，
-所以实现了一个粗糙版本的文件名批量命名工具，根据顺序排序重命名。
-
-安装方式，需要先配置 Golang 的运行环境，在工程根路径下执行：
-
-```bash
-./install.sh --tool renameV1
-```
-
-只想构建不安装时，可以执行：
+构建 Go CLI：
 
 ```bash
 ./build.sh
 ```
 
-### 使用方法
-
-1. 先在需要重命名的文件夹中输出一个配置文件；
-2. 修改配置文件中筛选文件的后缀名，重命名规则等，用于分别重命名外挂字幕和视频内容；
-3. 更新执行程序，更新配置文件；
-4. 手动修改配置文件中的文件顺序，文件名 `skip` 表示占位，用于下载的视频缺了一两集的情况，序号会跳过 1；
-5. 执行程序，确认更新；
-
-```bash
-Usage of ./renameV1:
-  -conf_file_name string
-        工作配置文件的文件名称 (default "rename_v1.json")
-  -create_conf int
-        创建配置文件 层级数量
-  -dir string
-        工作路径 (default "./")
-  -rename
-        依据配置文件执行重命名操作
-  -skip_double_check
-        跳过命令行二次确认
-  -update_conf
-        更新配置文件
-```
-
-## check_keywords
-
-程序员难免在闲暇时写点小的脚本和小工具，如果不小心引用了公司的依赖，或者用了公司的内部代码，可能会导致很严重的后果。
-
-利用 git hook 进行敏感信息检查，检查新增的行中是否包含敏感词。比如将公司的内部 git 地址作为敏感词，
-每次 git commit 时检测到新增的行中包含敏感词，就会拒绝提交。
-
-1. 检测敏感词；
-2. 检测正则表达式；
-
-
-## file_share
-
-`file_share` 是一个临时 HTTP 文件分享工具。传入一个或多个文件、目录即可启动只读 HTTP 服务，浏览器可以查看共享范围内的目录列表、打开文件、下载文件，也可以把目录打包成 zip 下载。
-
-安装：
-
-```bash
-./install.sh --tool file_share
-```
-
-简单分享：
-
-```bash
-file_share /path/to/file-or-dir
-file_share -addr 127.0.0.1:9000 /path/a /path/b
-```
-
-通过 JSON 指定共享范围：
-
-```bash
-file_share -config /etc/life_tools/file_share.json
-```
-
-配置示例在 `sample/life_tools/file_share.json`，完整说明见：[docs/file_share.md](docs/file_share.md)。这个工具默认无认证、显示隐藏文件、跟随符号链接，不要把含敏感文件或敏感链接的目录暴露到不可信网络。
-
-## codex_hook_notify
-
-Codex 生命周期提醒工具。程序从 stdin 读取 Codex hook JSON，根据事件类型把提醒发送到飞书自定义机器人。当前处理：
-
-1. `Stop`：Codex 本轮完成或停止。工具会优先读取本机 `CODEX_HOME/sessions`（默认 `~/.codex/sessions`）里的 transcript，推送最后一轮 Codex 用户可见输出；如果读不到 transcript，就回退到 hook 输入里的 `last_assistant_message`。
-2. `PermissionRequest`：Codex 等待用户批准执行命令或工具。
-
-所有通知都会带 `Machine:` 字段。配置文件顶层 `machine_name` 非空时优先使用它；未配置或为空时使用操作系统 hostname；仍取不到时显示 `unknown`。
-
-`Stop` 内容较长时会拆成多条飞书 text 消息发送。推送内容按 Codex 输出原样发送，不做敏感信息脱敏；不要把真实 webhook 配到不可信群里。
-
-配置文件默认路径：`/etc/life_tools/codex_hook_notify.json`。示例配置在 `sample/life_tools/codex_hook_notify.json`。完整使用说明见 `docs/codex_hook_notify.md`。
-
-```json
-{
-  "machine_name": "home-nas",
-  "routes": [
-    {
-      "events": ["Stop"],
-      "feishu_custom_robot_urls": ["https://open.feishu.cn/open-apis/bot/v2/hook/xxx"]
-    },
-    {
-      "events": ["PermissionRequest"],
-      "feishu_custom_robot_urls": ["https://open.feishu.cn/open-apis/bot/v2/hook/yyy"]
-    }
-  ]
-}
-```
-
-安装：
-
-```bash
-./install.sh --tool codex_hook_notify
-```
-
-默认安装只会构建程序、安装 `/usr/local/bin/codex_hook_notify`、创建配置样例和日志目录，不会修改 Codex 全局 hook。确认配置后，显式执行下面命令安装 `Stop` hook：
-
-```bash
-./install.sh --tool codex_hook_notify --install-codex-hook
-```
-
-`PermissionRequest` 在 approval 模式下提醒很多，默认不安装；如果旧版本已经安装过本工具的 `PermissionRequest` hook，默认安装命令会把它移除。确实需要审批提醒时再显式安装：
-
-```bash
-./install.sh --tool codex_hook_notify --install-codex-hook --with-permission-request
-```
-
-日志目录按系统选择：Linux 使用 `/var/log/codex_hook_notify`，macOS 使用 `~/Library/Logs/codex_hook_notify`，其他系统使用 `~/.codex_hook_notify/logs`。发送失败只写 stderr 和日志，程序仍返回 0，不阻塞 Codex。
-
-## video_subtitle
-
-给单个视频生成简体中文字幕的 Python 工具。它会抽取音频、调用火山 ASR、用 LLM 做字幕切分和翻译，并在视频同目录输出 `.zh-CN.srt`。
-
-完整使用说明、工作流程、项目结构和排障方法见：[docs/video_subtitle.md](docs/video_subtitle.md)。Emby 后端插件见：[docs/emby_video_subtitle_plugin.md](docs/emby_video_subtitle_plugin.md)。
-
-安装：
-
-```bash
-./install.sh --tool video_subtitle
-```
-
-安装 Python 依赖：
+Python CLI 语法检查：
 
 ```bash
-python3 -m pip install -r video_subtitle/requirements.txt
+PYTHONDONTWRITEBYTECODE=1 python3 -m py_compile \
+  cli/video_subtitle/video_subtitle.py \
+  cli/video_subtitle/video_subtitle_test.py \
+  cli/video_subtitle/lib/*.py
 ```
 
-也可以让安装脚本顺手安装 Python 依赖：
+Emby 插件验证：
 
 ```bash
-./install.sh --tool video_subtitle --with-python-deps
+dotnet test emby_plugins/video_subtitle/LifeTools.Emby.VideoSubtitle.sln
+dotnet build emby_plugins/video_subtitle/LifeTools.Emby.VideoSubtitle.sln
 ```
 
-配置文件示例在 `sample/life_tools/video_subtitle.json`，真实配置默认放到 `/etc/life_tools/video_subtitle.json`。
-
-生成字幕：
+InterviewTimer 验证：
 
 ```bash
-video_subtitle --input /path/to/video.mp4
+cd gui/interview_timer
+swift test
+swift build --product InterviewTimerApp
+./scripts/build_app.sh
 ```
 
-常用调试命令：
+具体工具的测试和排障入口见各自详细文档。
 
-```bash
-# 只重跑翻译，复用 ASR 和切分缓存
-video_subtitle --input /path/to/video.mp4 --force-translate
+## 发布
 
-# 跳过 ASR，强制从 ASR words 的 LLM 切分和翻译开始
-video_subtitle --input /path/to/video.mp4 --force-split --force-translate
-```
+推送 `v*` tag 会通过 GitHub Actions 构建 GitHub Release 资产，包括 Linux/macOS Go 二进制包、`video_subtitle` 源码包、Emby 插件包和未签名的 `InterviewTimer.app` 包。发布流程见 [docs/release.md](docs/release.md)。

+# check_keywords 敏感词检查工具
+
+`check_keywords` 从 stdin 读取内容，只检查以 `+` 开头的行，用于 git diff 新增内容中的敏感词拦截。它适合放在个人公开仓库的 pre-commit hook 中，避免把内部域名、私有依赖、敏感词或项目代号误提交出去。
+
+## 设计目标
+
+| 目标 | 处理方式 |
+|---|---|
+| 只检查新增内容 | `PrepareContents` 只保留首字符为 `+` 的行 |
+| 不把真实敏感词写入仓库 | 真实配置从本机 JSON 文件读取 |
+| 适配大 diff | 按 `-parallel` 把行切分成多个批次并发检查 |
+| hook 友好 | 命中时退出码为 `1`，未命中时退出码为 `0` |
+
+## 代码结构
+
+| 路径 | 作用 |
+|---|---|
+| `cli/check_keywords/main.go` | 参数解析、读取 stdin、加载配置、控制退出码 |
+| `cli/check_keywords/config.go` | JSON 配置结构和加载 |
+| `cli/check_keywords/find.go` | 并发切分、大小写不敏感的关键词匹配 |
+| `cli/check_keywords/git-hooks/pre-commit` | git pre-commit 示例脚本 |
+| `sample/life_tools/check_keywords.json` | 示例配置 |
+
+## 使用方法
+
+安装：
+
+```bash
+./install.sh --tool check_keywords
+```
+
+手工检查当前 diff：
+
+```bash
+git diff HEAD | check_keywords
+```
+
+静默模式适合 hook：
+
+```bash
+git diff HEAD | check_keywords -quiet
+```
+
+指定配置和并发：
+
+```bash
+git diff HEAD | check_keywords -config /etc/life_tools/check_keywords.json -parallel 4
+```
+

+# renameV1 批量重命名工具
+
+`renameV1` 是一个按配置批量重命名文件的 CLI。当前主要面向媒体库文件名整理：先生成或更新配置，再人工确认文件顺序，最后执行真实重命名。
+
+## 设计目标
+
+| 目标 | 处理方式 |
+|---|---|
+| 降低手工重命名成本 | 用 `rename_v1.json` 描述后缀过滤、目标命名规则和文件顺序 |
+| 保留人工确认 | 默认每个写操作前都要求输入 `y`，除非显式传 `-skip_double_check` |
+| 避免目标名互相覆盖 | 执行重命名时先改成带 UUID 的临时名，再改成最终名 |
+| 支持缺集占位 | `fileNames` 中的 `skip` 只推进集数，不参与真实文件重命名 |
+
+## 代码结构
+
+| 路径 | 作用 |
+|---|---|
+| `cli/renameV1/main.go` | CLI 参数解析和执行入口 |
+| `cli/renameV1/param.go` | 参数结构 |
+| `cli/renameV1/config.go` | 配置结构、配置读写和示例配置生成 |
+| `cli/renameV1/file.go` | 目录扫描、后缀过滤、路径拼接 |
+| `cli/renameV1/program.go` | `create_conf`、`update_conf`、`rename` 三种模式的主流程 |
+| `cli/renameV1/rename.go` | 目标文件名生成、冲突检查、两阶段重命名 |
+| `cli/renameV1/double_check.go` | 交互式二次确认 |
+| `cli/renameV1/testData/` | 单测使用的媒体文件、nfo、bif 示例 |
+
+## 使用方法
+
+安装：
+
+```bash
+./install.sh --tool renameV1
+```
+
+只构建：
+
+```bash
+./build.sh
+```
+
+常用流程：
+
+```bash
+# 1. 在目标目录生成配置，数字表示生成几组规则
+renameV1 -dir /path/to/media -create_conf 1
+
+# 2. 按当前目录文件更新 fileNames
+renameV1 -dir /path/to/media -update_conf
+
+# 3. 人工编辑 rename_v1.json，确认文件顺序和命名规则
+
+# 4. 执行重命名
+renameV1 -dir /path/to/media -rename
+```
+
+参数：
+
+| 参数 | 默认值 | 说明 |
+|---|---|---|
+| `-dir` | `./` | 工作目录 |
+| `-conf_file_name` | `rename_v1.json` | 配置文件名 |
+| `-create_conf` | `0` | 创建示例配置，值表示配置组数量 |
+| `-update_conf` | `false` | 按当前目录文件刷新 `fileNames` |
+| `-rename` | `false` | 根据配置执行真实重命名 |
+| `-skip_double_check` | `false` | 跳过命令行二次确认 |
+
+## 配置结构
+
+示例配置在 `sample/life_tools/rename_v1.json`。
+
+| 字段 | 说明 |
+|---|---|
+| `configs[]` | 多组重命名规则，可分别处理视频、字幕等文件 |
+| `postfix` | `update_conf` 扫描目录时使用的后缀过滤列表 |
+| `policy.name` | 目标文件名模板，`{Ep}` 会被替换成集数 |
+| `policy.num_start` | 起始集数 |
+| `policy.num_interval` | 每个文件递增的集数间隔 |
+| `policy.rename_filename_extension` | 是否把模板里的后缀当作最终后缀 |
+| `policy.ep_digit_count` | 集数补零位数 |
+| `fileNames` | 待重命名文件顺序，`skip` 表示缺集占位 |
+
+## 核心流程
+
+```mermaid
+flowchart TD
+    A["解析 CLI 参数"] --> B{"create_conf > 0?"}
+    B -->|是| C["生成示例配置并写入 rename_v1.json"]

+    J -->|否| L["两阶段 os.Rename"]
+    K --> L
+    G -->|否| M["结束"]
+    L --> M
+```
+
+## 风险边界
+
+- `-rename` 会调用 `os.Rename` 修改真实文件名，不要直接在不可恢复的媒体库目录试新规则。
+- `-skip_double_check` 会跳过覆盖配置和重命名确认，只应在可回滚的测试目录使用。
+- 当前 `filterFileName` 直接按后缀长度切片，`postfix` 不应配置成长于文件名的字符串。
+- 冲突检查只检查最终文件名冲突；执行过程中如果磁盘、权限或外部进程改动文件，仍可能失败。

+# retry_exec 命令重试工具
+
+`retry_exec` 用来包装任意命令，为它增加失败重试、指数退避、本地日志和失败通知。它适合放在 crontab、简单脚本或个人自动化任务里，处理偶发失败。
+
+## 设计目标
+
+| 目标 | 处理方式 |
+|---|---|
+| 不改变被包装命令的输入输出 | 子进程复用当前 stdin，stdout/stderr 继续透传 |
+| 失败后自动重试 | `Retry.Try` 递归执行命令，失败后按配置 sleep |
+| 避免通知过长 | 只保留 stdout/stderr 最后 4KB，通知优先带 stderr |
+| 支持多通知渠道 | 当前支持飞书自定义机器人、企业微信机器人和 Gotify |
+
+## 代码结构
+
+| 路径 | 作用 |
+|---|---|
+| `cli/retry_exec/retry_exec.go` | CLI 入口、配置读取、日志初始化 |
+| `cli/retry_exec/param.go` | JSON 配置结构 |
+| `cli/retry_exec/retry.go` | 命令执行、重试、退避和输出尾部截取 |
+| `cli/retry_exec/tail_writer.go` | 固定大小尾部缓存 |
+| `cli/retry_exec/notify.go` | 飞书、企业微信、Gotify 通知 |
+| `sample/life_tools/retry_exec.json` | 示例配置 |
+
+## 使用方法
+
+安装：
+
+```bash
+./install.sh --tool retry_exec
+```
+
+包装命令：
+
+```bash
+retry_exec curl -f https://example.com/health
+```
+
+指定配置：
+
+```bash
+retry_exec --config /etc/life_tools/retry_exec.json curl -f https://example.com/health
+```
+
+## 配置结构
+
+默认配置路径是 `/etc/life_tools/retry_exec.json`。
+
+| 字段 | 说明 |
+|---|---|
+| `retry_times` | 总尝试次数。小于等于 1 时失败后不再重试 |
+| `retry_interval` | 初始重试间隔，单位毫秒 |
+| `max_retry_interval` | 最大重试间隔，单位毫秒 |
+| `feishu_custom_robot_url` | 飞书自定义机器人 webhook |
+| `wechat_robot_url` | 企业微信机器人 webhook |
+| `gotify_config.server_url` | Gotify 服务地址 |
+| `gotify_config.token` | Gotify token |
+| `log` | 本地日志目录 |
+
+macOS 安装脚本会把默认日志目录调整为 `~/Library/Logs/retry_exec`；Linux 默认是 `/var/log/retry_exec`。
+
+## 核心流程
+
+```mermaid
+flowchart TD
+    A["解析 --config 和被包装命令"] --> B["读取 retry_exec.json"]

+    J --> K["发送配置的失败通知"]
+    K --> L["用子命令 exit code 退出"]
+```
+
+## 失败通知
+
+通知内容包含：
+
+| 内容 | 来源 |
+|---|---|
+| 命令参数 | `commands` |
+| exit code | 子命令退出码 |
+| Go error | 子进程执行错误 |
+| 输出尾部 | 优先 stderr，stderr 为空时使用 stdout，最多 4KB |
+
+## 风险边界
+
+- `runtime.GOMAXPROCS(1)` 当前限制为单线程，适合轻量包装，不适合高吞吐任务调度。
+- 命令参数来自 `os.Args`，不是 shell 字符串；需要 shell 展开时显式包装为 `sh -c '...'`。
+- 通知失败只写日志，不会改变最终退出码。
+- 重试会重复执行副作用命令，写库、发消息、扣费等操作不要直接套用。
