Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# PPT 做课
用户明确要求用 PPT 做课时，按「两阶段」流程操作：先提交 PPT 拿每页图片，再逐页写口播文案提交制作。
## 第一阶段：提交 PPT
调用 `start_ppt_course`，为一次做课生成稳定的 `request_key`，重试时复用。`title` 在转换阶段使用附件文件名（去掉扩展名）作为临时标题，不要在上传前要求用户填写最终课程信息。
- 可以使用用户给出的 HTTPS 文件链接。
- 用户在当前对话中发送了 PPT/PPTX/PDF 附件时，优先使用 WorkBuddy 提供的真实附件路径，不要求用户再次选择文件。先调用 `start_ppt_course`（不传 `source_url`），再把该附件以 `multipart/form-data` 上传到返回的 `upload_url`，表单字段使用返回的 `upload_field`（当前为 `file`），并请求 JSON 响应。上传动作必须由本机文件上传能力完成，不把文件二进制或 Base64 放进 MCP JSON。
- 只有 WorkBuddy 确实没有暴露可读取的附件路径、或者本机上传能力不可用时，才把 `upload_url` 作为兜底页面交给用户手工上传。不得在附件可用时先打开上传页面。
- 直接上传成功后继续使用原 `job_id` 查询进度；不要再次调用 `start_ppt_course` 创建新任务。签名地址过期时，复用同一个 `request_key` 获取当前任务状态，不猜测或改写签名参数。
用 `get_ppt_course_status` 轮询，直到 `stage` 变为 `awaiting_scripts`。此时返回体中的 `pages` 为逐页 `{index, image_url}`，即可开始写文案。
- 优先直接使用 `image_url` 查看每页图片，不把图片保存到用户的下载目录。
- 视觉工具必须读取本地文件时，只下载到临时缓存目录，识别完成后立即删除，不把临时文件作为产物展示给用户。
- 工具返回的 `index` 从 0 开始；向用户展示时统一转换为从 1 开始的“第 N 页”。
## 第二阶段：提交文案生成草稿或视频
逐页看图后，根据整份 PPT 自动生成建议课程标题、课程描述和逐页口播文案。`scripts` 数组长度必须与 `pages` 一致并严格按页序。
调用提交工具前必须完成以下审核循环：
1. 一次性展示完整建议内容：课程标题、课程描述，以及每页 PPT 图片和对应口播文案。
2. 明确提示用户可以直接确认，也可以修改标题、描述、指定页文案或整体语气、长度和风格。
3. 用户提出修改后更新对应内容，并重新展示包含全部页面的完整最新版；不得只展示修改页后直接提交。

How to install
mdr add infometa/workbuddyskills/ppt-course@sha256:a861712fbcd83c2dThe line at the top of this page pins the label git:20261004.0dd7831, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
