PPX Parse

Use the local ppx CLI to parse PDFs and images into structured Markdown and JSON.

Runtime Requirements

Use Python >= 3.12.

Prefer installing PPX into a virtual environment instead of the system Python.

If ppx is missing, read references/troubleshooting.md and create a virtual environment before installing dependencies.

Keep this skill's frontmatter version synchronized from the repository pyproject.toml with scripts/sync_version.py.

Workflow

1. Confirm the runtime uses Python >= 3.12. 2. Check the runtime with scripts/check_ppx_env.sh. 3. If ppx is missing, create or use a virtual environment and install PPX there. 4. Choose parsing options: - Use --ocr auto by default. - Use --ocr yes for scanned PDFs or screenshots. - Use --ocr no for native PDFs when OCR causes noise. - Use --table auto by default. - Use --table llm only when the user needs highest table accuracy and an LLM backend is configured. 5. Run ppx parse -o

. 6. Inspect the output folder and report the main artifacts: - doc.md - doc.json - pages/ - images/ when figures are extracted 7. If parsing fails, summarize the failing step and load the relevant note from references/.

Common Commands

ppx parse report.pdf -o output/
ppx parse scan.pdf --ocr yes -o output/
ppx parse figure.png -o output/
ppx parse report.pdf --pages "1-5,10" -o output/
ppx parse report.pdf --table llm --backend deepseek -o output/

Output Contract

Prefer returning the absolute output directory.

Mention whether the result came from doc.md, doc.json, or page-level files.

Call out OCR mode, table mode, and backend when they materially affect accuracy.

References

Read references/cli-options.md when choosing parse flags.

Read references/backend-config.md when using DeepSeek, Paddle, or GLM backends.

Read references/troubleshooting.md when PPX is missing, Python is too old, or runtime dependencies fail.
