+description: 读取禅道（njlkairport.chandao.net，开源版 18.8）中的 Bug 单——我的 Bug 列表、单个 Bug 的标题/描述/截图/评论/修改历史/附件——并按 AirLogistics 项目规范定位代码完成修复。禅道 18.8 没有 API 2.0，官方 zentao-cli / MCP 不可用，必须用本 skill 的 zentao.py。当用户提到"禅道"、"bug 单"、"我的 bug"、"修 bug"、"处理 bug"、给出 Bug 编号（如 "#632"、"bug 632"）或禅道链接（bug-view-xxx.html / my-work-bug.html）时使用。
+---
+
+# 禅道 Bug 读取与修复
+
+## 工具
+
+```bash
+Z=.claude/skills/zentao-bug/zentao.py
+python3 $Z whoami                         # 当前账号 + 会话是否有效
+python3 $Z list                           # 指派给我的 Bug（= 网页「地盘 → 我的Bug」）
+python3 $Z list --status active           # 只看激活的
+python3 $Z list --type resolvedBy         # 由我解决 / openedBy / closedBy
+python3 $Z list --json                    # 结构化输出
+python3 $Z view 632                       # Bug 详情（Markdown）
+```
+
+`view` 输出并保存到 `~/.cache/zentao-lite/bugs/<id>/bug.md`：基本信息、重现步骤、附件、历史记录与评论（评论以 `>` 引用块呈现）。
+描述和评论中的截图下载到 `images/`，文中以绝对路径 `![图N](/Users/.../images/1154.jpeg)` 引用。
+
+**截图是需求的主要载体**（团队习惯把原型/标注贴在描述和评论里，几乎不用附件），**必须逐张用 Read 查看**，不能只看文字。
+
+## 登录（只能由用户本人执行）
+
+退出码 2 表示未登录或会话过期。禅道会话默认空闲 24 分钟失效。让用户在自己的终端执行：
+
+```bash
+python3 .claude/skills/zentao-bug/zentao.py login --account <账号>
+```
+
+密码交互输入、不回显；默认存入 macOS 钥匙串，此后会话过期会自动重新登录（`--no-keychain` 则不保存）。
+**不要向用户索要密码，也不要替用户在命令行里带密码登录。**
+
+## 修复流程
+
+1. **读单**：`view <id>`，Read 全部截图；评论里常有后续补充或改口，以最新评论为准。
+2. **定位页面**：Bug 标题/描述通常写的是菜单名（如"出港移库""进港仓库"）。按 CLAUDE.md「页面定位规则」，
+   以首页菜单实际跳转的 Activity 为准（平板 `app/.../HomeFragment.kt`，手机 `module_p` 的 `GnViewModel`/`GjViewModel`）。
+3. **判断端**：截图是手机竖屏（如 5.5 寸设计稿样式）还是平板横屏，决定改 `res/layout/` 还是 `res/layout-sw600dp/`；
+   业务逻辑改动两端都要检查（CLAUDE.md「业务以平板为准」）。截图提到"原型"时对照 `documents/5.5寸手持端设计文件/`。
+4. **修改并验证**：遵守 CLAUDE.md 的 UI 规范；`./gradlew assembleDebug` 编译通过；能在模拟器验证的就验证并截图比对。
+5. **汇报**：按 Bug 逐条说明改了什么、改在哪里、如何验证、有无未覆盖项。多个 Bug 时每个 Bug 单独提交，
+   提交信息带 `Bug #<id>`。不确定截图意图时先问用户，禁止臆测。
+
+## 写回禅道
+
+暂未实现（写操作会改动线上 Bug 状态，需用户确认后再加）。修复完成后由用户在禅道手动"解决"，
+可附上提交号与改动摘要供用户粘贴。
+
+## 实现说明
+
+- 认证：`POST /api.php/v1/tokens` 换 Token；数据走页面 JSON 模式（`.html` → `.json`），Cookie `zentaosid=<Token>`。
+- 接口：`/my-work-bug-<type>-0-id_desc-0-<perPage>-<page>.json`、`/bug-view-<id>.json`、`/file-read-<fileID>.<ext>`。
+- REST v1 的 `/products/<id>/bugs` 只返回激活中的 Bug，不能替代"我的 Bug"页面。
+- 凭据：Token 在 `~/.config/zentao-lite/config.json`（0600），密码只在钥匙串（服务名 `zentao-lite`）。`logout` 一并清除。
