+name: transfer-failed-retry
+description: Use this skill when you need to retry a failed file transfer/organization. Given a failed transfer history record ID, this skill guides you through querying the failure details, deleting the old record, and re-identifying and re-organizing the file. This skill is automatically triggered when the system detects a transfer failure and the AI agent retry feature is enabled.

+# Transfer Failed Retry (整理失败重试)
+
+This skill handles retrying failed file transfers/organizations. When a file transfer fails, you can use this skill to analyze the failure, remove the stale history record, and attempt to re-identify and re-organize the file.
+
+## Prerequisites
+
+You need the following tools:
+- `query_transfer_history` - Query transfer history records
+- `delete_transfer_history` - Delete a transfer history record
+- `recognize_media` - Recognize media info from file path or title
+- `transfer_file` - Transfer/organize files to the media library
+- `search_media` - Search TMDB for media information
+
+## Workflow
+
+### Step 1: Query the Failed Transfer History
+
+Use `query_transfer_history` to get details about the failed record. Filter by status `failed` to find the specific record.
+
+If you are given a specific history record ID, query with that ID to understand the failure context:
+
+```
+query_transfer_history(status="failed")
+```
+
+From the record, extract the following key information:
+- **id**: The history record ID
+- **src**: Source file path
+- **title**: The recognized title (may be incorrect)
+- **errmsg**: The error message explaining why the transfer failed
+- **type**: Media type (movie/tv)
+- **tmdbid**: TMDB ID (if available)
+- **seasons/episodes**: Season/episode info (if TV show)
+- **downloader**: Which downloader was used
+- **download_hash**: The torrent hash
+
+### Step 2: Analyze the Failure Reason
+
+Common failure reasons and how to handle them:
+
+| Error Message | Cause | Solution |
+|---------------|-------|----------|
+| 未识别到媒体信息 | File name couldn't be matched to any media | Use `search_media` to find the correct TMDB ID, then use `transfer_file` with explicit `tmdbid` |
+| 源目录不存在 | Source file was moved or deleted | Cannot retry - skip this record |
+| 目标路径不存在 | Target directory issue | Retry transfer - the directory config may have been fixed |
+| 文件已存在 | Target file already exists | May need to use `force` mode or skip |
+| 未找到有效的集数信息 | Episode number not recognized | Use `recognize_media` with the file path to get better metadata, or specify season/episode in `transfer_file` |
+| 未获取到转移目录设置 | No transfer directory configured for this media type | Cannot auto-fix - notify user about directory configuration |
+
+### Step 3: Delete the Failed History Record
+
+Before retrying, you **must** delete the old failed history record. The system skips files that already have a transfer history entry (even failed ones).
+
+```
+delete_transfer_history(history_id=<record_id>)
+```
+
+### Step 4: Re-identify and Re-organize
+
+Based on the failure analysis in Step 2:
+
+#### Case A: Unrecognized Media (未识别到媒体信息)
+
+1. Try recognizing the media from file path:
+   ```
+   recognize_media(path="<source_file_path>")
+   ```
+
+2. If recognition fails, try searching TMDB with keywords extracted from the filename:
+   ```
+   search_media(title="<extracted_title>", media_type="movie" or "tv")
+   ```
+
+3. Once you have the correct TMDB ID, re-transfer with explicit identification:
+   ```
+   transfer_file(file_path="<source_path>", tmdbid=<tmdb_id>, media_type="movie" or "tv")
+   ```
+
+#### Case B: Transfer Error (file operation failed)
+
+Simply retry the transfer:
+```
+transfer_file(file_path="<source_path>")
+```
+
+#### Case C: Episode Recognition Issue
+
+For TV shows where episode info couldn't be determined:
+1. Use `recognize_media` to get better metadata
+2. Re-transfer with explicit season info:
+   ```
+   transfer_file(file_path="<source_path>", tmdbid=<tmdb_id>, media_type="tv", season=<season_number>)
+   ```
+
+### Step 5: Report Result
+
+After the retry attempt, report the result:
+- If successful: Confirm the file has been organized correctly
+- If failed again: Report the new error and suggest manual intervention
+
+## Important Notes
+
+- **Always delete the old history record first** before retrying. The system will skip files with existing history.
+- **Do not retry** if the source file no longer exists (源目录不存在).
+- **Do not retry** if the error is about missing directory configuration - this requires user intervention.
+- **For unrecognized media**, always try `recognize_media` with the file path first before falling back to `search_media`.
+- **Be cautious with TV shows** - ensure the correct season and episode information is used.
+- When this skill is triggered automatically by the system, it provides the `history_id` directly. Start from Step 1 with that specific ID.
+
+## Example: Complete Retry Flow
+
+```
+# 1. Query the failed record
+query_transfer_history(status="failed", page=1)
+# Found: id=42, src="/downloads/Movie.Name.2024.1080p.mkv", errmsg="未识别到媒体信息"
+
+# 2. Try to recognize the media from path
+recognize_media(path="/downloads/Movie.Name.2024.1080p.mkv")
+# Recognition failed
+
+# 3. Search TMDB
+search_media(title="Movie Name", year="2024", media_type="movie")
+# Found: tmdb_id=123456
+
+# 4. Delete old history record
+delete_transfer_history(history_id=42)
+
+# 5. Re-transfer with correct identification
+transfer_file(file_path="/downloads/Movie.Name.2024.1080p.mkv", tmdbid=123456, media_type="movie")
+# Success!
+```
