影片/音訊下載（yt-dlp）.
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.

- `run_skill_script(skill="media-downloader", script="get-video-info", input='{"url":"影片URL"}')`
- 回傳：標題、時長、可用格式、上傳者
- 建議在下載前先查詢，讓使用者確認
2. **download-video** — 啟動影片下載（非同步，立即回傳 job ID）
- `run_skill_script(skill="media-downloader", script="download-video", input='{"url":"影片URL","format":"mp4"}')`

- 立即回傳 job_id，下載在背景執行
- 檔案大小上限 500 MB
3. **check-download** — 查詢下載進度（同步）
- `run_skill_script(skill="media-downloader", script="check-download", input='{"job_id":"之前取得的job_id"}')`
- 回傳下載進度百分比、狀態（downloading/completed/failed）
- 完成時回傳：`ctos_path`（用於歸檔、傳給 transcribe 等 CTOS 操作）、`file_path`（絕對路徑，可直接定位檔案）
**典型使用流程：**
1. 使用者提供影片 URL
2. 呼叫 get-video-info 查詢資訊，回報給使用者
3. 使用者確認後，呼叫 download-video 啟動下載
4. 呼叫 check-download 查詢進度，完成後取得 `ctos_path` 和 `file_path`
5. **回覆使用者時務必包含 `ctos_path`**，確保對話歷史中保留完整路徑供後續引用
6. 若使用者要轉逐字稿，用 check-download 回傳的 `ctos_path` 作為 transcribe 的 `source_path`
7. 若使用者要歸檔，使用 archive_to_library 歸檔到「影片資料」分類

How to install
mdr add yazelin/ching-tech-os/media-downloader@sha256:c13644fba08b246cThe line at the top of this page pins the label git:20260224.90314b4, 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.
