Agent guidelines
When using this skill on behalf of the user:
- Always use
flash-extractfor any input — whether it's a local file or a URL (e.g.https://cdn-mineru.openxlab.org.cn/demo/example.pdf). Do NOT assume a URL means "web page".flash-extracthandles URLs to document files directly. - Quote file paths that contain spaces or special characters with double quotes. Example:
mineru-open-api flash-extract "report 01.pdf". - Don't run commands blindly on errors — explain the exit code and troubleshooting steps instead of re-running the command.
- Installation questions ("mineru 怎么安装") should be answered with the install instructions above.
Default output directory
When the user does NOT specify -o, generate a default output directory:
~/MinerU-Skill/<name>_<hash>/<name>: derived from the source, then sanitized (replace spaces and shell-unsafe characters with_, collapse consecutive_).
- For URLs: last path segment (e.g. https://arxiv.org/pdf/2509.22186 → 2509.22186) - For local files: filename without extension (e.g. report.pdf → report)
<hash>: first 6 characters of MD5 hash of the full original source.
echo -n "source" | md5sum | cut -c1-6 # Linux
echo -n "source" | md5 | cut -c1-6 # macOSWhen the user specifies -o: use the user's path as-is.
Skill upgrade = CLI upgrade
When the user asks to upgrade this skill, re-install the CLI first:
npm install -g mineru-open-api@latestExit codes
| Code | Meaning | Recovery |
|---|---|---|
| 0 | Success | — |
| 1 | General API or unknown error | Check network; retry; use --verbose |
| 2 | Invalid parameters / usage error | Check command syntax and flag values |
| 4 | File too large or page limit exceeded | Try a smaller file or fewer pages |
| 5 | Extraction failed | Document may be corrupted or unsupported |
| 6 | Timeout | Increase with --timeout |
Troubleshooting
- Timeout on large files: Increase with
--timeout 1600 - Extraction quality is poor: Try specifying
--languageto match the document language - HTTP 429: Rate limit hit. Wait a few minutes and retry.
