+# Cron Scheduler — 定时任务调度
+
+基于 cron 表达式的定时任务和一次性提醒。
+
+## 工具说明
+
+### cron
+创建和管理 Beaver 定时通知或 Task。
+- `action` (str): `add` | `list` | `remove` | `toggle` | `run`
+- `message` (str): 触发时执行的任务说明，`add` 时必填
+- `schedule` (str): 调度表达式，例如 `every 15m`、`0 9 * * *` 或 ISO 时间
+- `every_seconds` (int | None): 固定秒级间隔
+- `cron_expr` (str | None): 标准 5 段 cron 表达式
+- `tz` (str | None): IANA 时区，例如 `Asia/Shanghai`
+- `at_iso` (str | None): 一次性任务的 ISO 时间
+- `job_id` (str | None): `remove`、`toggle`、`run` 目标任务 ID
+- `enabled` (bool | None): `toggle` 时设置启停状态
+- `mode` (str | None): `notification` 或 `task`
+- `requires_followup` (bool | None): task 模式下是否需要用户跟进
+
+## 使用原则
+
+1. 避开 :00 和 :30 整点分钟，分散负载
+2. 一次性提醒优先使用 `at_iso` 或清晰的 `schedule`
+3. 需要持续提醒时使用 `mode="notification"`，需要 Task 跟踪时才用 `mode="task"`
+4. 定期用 `action="list"` 确认任务是否按预期调度
+5. 任务触发时 `message` 会完整执行，确保内容自包含

+# Filesystem Operation — 文件系统操作
+
+本地文件系统工具集，用于读写和搜索项目文件。
+
+## 工具说明
+
+### read_file
+读取本地文件内容。
+- 使用 `skill_view` 查看文件预览
+- 大文件会分页返回，可通过 offset/limit 控制
+
+### write_file
+写入新文件或覆盖已有文件。
+- 创建新文件时自动创建父目录
+- 写入前确认不会覆盖重要配置
+
+### patch_file
+精确修改文件中的指定内容。
+- 通过搜索-替换方式修改
+- 适用于局部更新，避免整文件重写
+
+### search_files
+在项目中搜索文件名或内容。
+- 支持 glob 模式匹配
+- 支持按内容搜索
+- 支持限制搜索目录深度
+
+### list_directory
+列出目录内容。
+- 可递归列出子目录
+- 支持过滤文件类型
+
+## 使用原则
+
+1. 优先使用 `read_file` 查看文件内容，再决定修改方案
+2. 小范围修改用 `patch_file`，大范围用 `write_file`
+3. 搜索文件时先确认路径是否存在
+4. 修改前确认文件编码（默认 UTF-8）
+5. 敏感文件（.env、密钥等）不写入版本控制

+  - `user`: 用户角色、职责、知识背景、稳定偏好
+  - `memory`: 项目约定、环境事实、稳定工具经验
+- 支持自动保存和检索
+- 跨会话持久化
+
+## 使用原则
+
+1. 了解用户角色偏好后及时保存到 `user` 类型
+2. 用户明确要求记住的内容立即保存
+3. 过时的记忆及时更新或删除
+4. 不保存可以从代码/git 推导出的信息
+5. 记忆是辅助参考，当前上下文和文件状态优先级更高

+# OfficeBench MCP Skill
+
+Use this skill for OfficeBench evaluation runs. OfficeBench task files live in the OfficeBench MCP server, not in Beaver's local filesystem. Complete the task by calling real `mcp_officebench_*` tools.
+
+## Critical Rules
+
+1. Use actual Beaver tool calls only. Do not print XML, DSML, JSON, or markdown that describes a tool call.
+2. Never invent tool names. If you need to find files, use `mcp_officebench_shell_list_directory` or `mcp_officebench_shell_command`.
+3. Do not use Beaver local filesystem, local runtime, local terminal, or local code tools for OfficeBench files.
+4. Paths are relative to `/testbed` in the OfficeBench MCP container, such as `data/score.xlsx`.
+5. If the task context gives a `workspace_id`, pass that same `workspace_id` argument in every OfficeBench MCP tool call that supports it.
+6. Inspect files before editing them.
+7. Verify the requested output file or edited cell exists before finishing.
+8. Finish every task with `mcp_officebench_system_finish_task`.
+
+## Tool Names And Use
+
+### Excel
+
+Use these for `.xlsx` files:
+
+- `mcp_officebench_excel_read_file`: read workbook sheets and cell values.
+  - Required: `file_path`
+  - Optional: `sheet_name`, `workspace_id`
+- `mcp_officebench_excel_set_cell`: write one cell.
+  - Required: `file_path`, `row`, `col`, `value`
+  - Optional: `sheet_name`, `workspace_id`
+  - Rows and columns are 1-based.
+- `mcp_officebench_excel_delete_cell`: clear one cell.
+  - Required: `file_path`, `row`, `col`
+  - Optional: `sheet_name`, `workspace_id`
+- `mcp_officebench_excel_create_new_file`: create a workbook.
+  - Required: `file_path`
+  - Optional: `workspace_id`
+- `mcp_officebench_excel_convert_to_pdf`: convert an Excel file to PDF.
+  - Required: `file_path`
+  - Optional: `workspace_id`
+
+Typical Excel sequence:
+
+1. Call `mcp_officebench_shell_list_directory` on `data`.
+2. Call `mcp_officebench_excel_read_file` on the target workbook.
+3. Identify the exact row and column.
+4. Call `mcp_officebench_excel_set_cell`.
+5. Read the workbook again or use status/listing to verify.
+6. Call `mcp_officebench_system_finish_task`.
+
+For the common task "change Bob's midterm1 score to 100 in score.xlsx", inspect `data/score.xlsx`, find Bob's row and the `midterm1` column, then call `mcp_officebench_excel_set_cell` with that row, that column, and value `100`.
+
+### Word
+
+Use these for `.docx` files:
+
+- `mcp_officebench_word_read_file`: read all paragraphs.
+  - Required: `file_path`
+  - Optional: `workspace_id`
+- `mcp_officebench_word_write_to_file`: overwrite or append text.
+  - Required: `file_path`, `text`
+  - Optional: `append`, `workspace_id`
+- `mcp_officebench_word_create_new_file`: create a new Word document.
+  - Required: `file_path`
+  - Optional: `workspace_id`
+- `mcp_officebench_word_convert_to_pdf`: convert Word to PDF.
+  - Required: `file_path`
+  - Optional: `workspace_id`
+
+Preserve exact spelling, capitalization, punctuation, and line order from source files.
+
+### Email
+
+Use these for email tasks:
+
+- `mcp_officebench_email_list_emails`: list available `.eml` messages.
+  - Optional: `folder`, `workspace_id`
+- `mcp_officebench_email_read_email`: read one email.
+  - Required: `email_path`
+  - Optional: `workspace_id`
+- `mcp_officebench_email_send_email`: create/send an email artifact.
+  - Required: `to`, `subject`, `body`
+  - Optional: `attachments`, `workspace_id`
+
+For email-search tasks, final answers should use plain text with literal lines like `Subject: ...`. Do not add markdown labels.
+
+### Calendar
+
+Use these for calendar `.ics` tasks:
+
+- `mcp_officebench_calendar_list_events`: inspect calendar events.
+  - Optional: `calendar_path`, `workspace_id`
+- `mcp_officebench_calendar_create_event`: create an event.
+  - Required fields depend on the task; include summary/title, start, end, and target calendar when needed.
+  - Optional: `workspace_id`
+- `mcp_officebench_calendar_delete_event`: delete an event.
+  - Required fields depend on the task; inspect events first.
+  - Optional: `workspace_id`
+
+Use the task's current date/time context when interpreting relative dates.
+
+### PDF, OCR, And Images
+
+Use these for PDF/image tasks:
+
+- `mcp_officebench_pdf_read_file`: extract text from a PDF.
+  - Required: `pdf_file_path`
+  - Optional: `workspace_id`
+- `mcp_officebench_pdf_convert_to_word`: convert PDF to Word.
+  - Required: `pdf_file_path`
+  - Optional: `workspace_id`
+- `mcp_officebench_pdf_convert_to_image`: convert one PDF page to an image.
+  - Required: `pdf_file_path`
+  - Optional: `page_number`, `dpi`, `workspace_id`
+- `mcp_officebench_ocr_recognize_file`: OCR an image.
+  - Required: `image_path`
+  - Optional: `language`, `workspace_id`
+- `mcp_officebench_image_convert_to_pdf`: convert image to PDF.
+  - Required: `image_path`
+  - Optional: `output_path`, `workspace_id`
+
+For conversion tasks, create the exact requested filename and verify it exists.
+
+### Shell And System
+
+Use these for safe file discovery and text files:
+
+- `mcp_officebench_shell_list_directory`: list a directory.
+  - Optional: `path`, `workspace_id`
+- `mcp_officebench_shell_read_file`: read text files such as `.txt`, `.csv`, `.json`, `.md`, `.xml`.
+  - Required: `file_path`
+  - Optional: `workspace_id`

+- `mcp_officebench_shell_command`: run shell commands inside the OfficeBench MCP container.
+  - Required: `command`
+  - Optional: `workdir`, `workspace_id`
+- `mcp_officebench_system_get_status`: inspect filesystem/git status.
+  - Optional: `workspace_id`
+- `mcp_officebench_system_finish_task`: mark the task complete and optionally write an answer.
+  - Optional: `answer`, `workspace_id`
+
+Prefer dedicated Office tools for Office documents. Use shell tools for listing directories, copying/renaming files, and reading/writing plain text.
+
+## Anti-Patterns
+
+Do not do any of the following:
+
+- Do not call `mcp_officebench_find_in_workspace`; that tool does not exist.
+- Do not output `<tool_calls>`, `<invoke>`, DSML, or pseudo tool call text.
+- Do not answer "done" without calling the required OfficeBench tools.
+- Do not edit guessed paths without first listing or reading relevant files.
+- Do not use `/testbed` as a literal prefix in path arguments unless a tool explicitly asks for an absolute path.
+- Do not correct misspellings found in source data. Preserve source text exactly.

+- `start_time` (str): 同步窗口开始
+- `end_time` (str): 同步窗口结束
+- `delta_link` (str | None): 增量续传链接
+- `top` (int, 默认 50)
+- `persist_cursor` (bool, 默认 true)
+- `cursor_key` (str, 默认 "calendar:primary")
+
+## 使用原则
+
+1. 邮件操作优先使用幂等键（idempotency_key）防止重复发送
+2. 日历时间参数统一使用 ISO 8601 格式

+# Terminal Operation — 终端与进程管理
+
+Shell 命令执行、后台进程管理和 Python 代码执行工具集。
+
+## 工具说明
+
+### terminal
+执行 shell 命令。
+- `command` (str): 要执行的命令
+- `working_dir` (str, 默认 "."): 工作目录
+- `timeout` (int, 默认 60): 超时秒数（最大 600）
+- `background` (bool, 默认 false): 是否后台运行
+- 后台运行时返回 process_id，可通过 process 工具管理
+
+### process
+管理后台进程。
+- `action` (str): `list` | `log` | `kill`
+- `process_id` (str | None): 进程 ID
+- `list`: 列出所有后台进程
+- `log`: 查看进程日志（最后 12000 字节）
+- `kill`: 终止进程（先 SIGTERM，5 秒后 SIGKILL）
+
+### execute_code
+执行 Python 代码片段。
+- `code` (str): Python 代码
+- `language` (str, 默认 "python"): 仅支持 python
+- `timeout` (int, 默认 30, 最大 120): 执行超时
+- `working_dir` (str, 默认 "."): 工作目录
+- 适合快速验证脚本逻辑，不适合长期运行任务
+
+## 使用原则
+
+1. 长期运行任务使用 `background=true`
+2. 执行危险命令（rm -rf、dd、格式化等）前必须确认用户意图
+3. `execute_code` 适合轻量脚本验证，重型任务用 `terminal`
+4. 后台进程用完后及时 kill 清理
+5. 注意命令注入风险，不要直接拼接用户输入
