PaddleOCR Document Parsing

When to Use This Skill

Use Document Parsing for: Documents with tables (invoices, financial reports, spreadsheets) Documents with mathematical formulas (academic papers, scientific documents) Documents with charts and diagrams Multi-column layouts (newspapers, magazines, brochures) Complex document structures requiring layout analysis Any document requiring structured understanding Use Text Recognition instead for: Simple text-only extraction Quick OCR tasks where speed is critical Screenshots or simple images with clear text

Installation

Install Python dependencies before using this skill. From the skill directory (skills/paddleocr-doc-parsing): pip install -r scripts/requirements.txt Optional — for document optimization and split_pdf.py (page extraction): pip install -r scripts/requirements-optimize.txt

How to Use This Skill

⛔ MANDATORY RESTRICTIONS - DO NOT VIOLATE ⛔ ONLY use PaddleOCR Document Parsing API - Execute the script python scripts/vl_caller.py NEVER parse documents directly - Do NOT parse documents yourself NEVER offer alternatives - Do NOT suggest "I can try to analyze it" or similar IF API fails - Display the error message and STOP immediately NO fallback methods - Do NOT attempt document parsing any other way If the script execution fails (API not configured, network error, etc.): Show the error message to the user Do NOT offer to help using your vision capabilities Do NOT ask "Would you like me to try parsing it?" Simply stop and wait for user to fix the configuration

Basic Workflow

Execute document parsing: python scripts/vl_caller.py --file-url "URL provided by user" --pretty Or for local files: python scripts/vl_caller.py --file-path "file path" --pretty Optional: explicitly set file type: python scripts/vl_caller.py --file-url "URL provided by user" --file-type 0 --pretty --file-type 0: PDF --file-type 1: image If omitted, the service can infer file type from input. Default behavior: save raw JSON to a temp file: If --output is omitted, the script saves automatically under the system temp directory Default path pattern: <system-temp>/paddleocr/doc-parsing/results/result_<timestamp>_<id>.json If --output is provided, it overrides the default temp-file destination If --stdout is provided, JSON is printed to stdout and no file is saved In save mode, the script prints the absolute saved path on stderr: Result saved to: /absolute/path/... In default/custom save mode, read and parse the saved JSON file before responding In save mode, always tell the user the saved file path and that full raw JSON is available there Use --stdout only when you explicitly want to skip file persistence The output JSON contains COMPLETE content with all document data: Headers, footers, page numbers Main text content Tables with structure Formulas (with LaTeX) Figures and charts Footnotes and references Seals and stamps Layout and reading order Input type note: Supported file types depend on the model and endpoint configuration. Always follow the file type constraints documented by your endpoint API. Extract what the user needs from the output JSON using these fields: Top-level text result[n].markdown result[n].prunedResult

IMPORTANT: Complete Content Display

• CRITICAL: You must display the COMPLETE extracted content to the user based on their needs.
• The output JSON contains ALL document content in a structured format
• In save mode, the raw provider result can be inspected in the saved JSON file
• Display the full content requested by the user, do NOT truncate or summarize
• If user asks for "all text", show the entire text field
• If user asks for "tables", show ALL tables in the document
• If user asks for "main content", filter out headers/footers but show ALL body text
• What this means:
• DO: Display complete text, all tables, all formulas as requested
• DO: Present content using these fields: top-level text, result[n].markdown, and result[n].prunedResult
• DON'T: Truncate with "..." unless content is excessively long (>10,000 chars)
• DON'T: Summarize or provide excerpts when user asks for full content
• DON'T: Say "Here's a preview" when user expects complete output
• Example - Correct:
• User: "Extract all the text from this document"
• Agent: I've parsed the complete document. Here's all the extracted text:
• [Display entire text field or concatenated regions in reading order]
• Document Statistics:
• Total regions: 25
• Text blocks: 15
• Tables: 3
• Formulas: 2
• Quality: Excellent (confidence: 0.92)
• Example - Incorrect:
• User: "Extract all the text"
• Agent: "I found a document with multiple sections. Here's the beginning:
• 'Introduction...' (content truncated for brevity)"

Understanding the JSON Response

The output JSON uses an envelope wrapping the raw API result: { "ok": true, "text": "Full markdown/HTML text extracted from all pages", "result": { ... }, // raw provider response "error": null } Key fields: text — extracted markdown text from all pages (use this for quick text display) result - raw provider response object result[n].prunedResult - structured parsing output for each page (layout/content/confidence and related metadata) result[n].markdown — full rendered page output in markdown/HTML Raw result location (default): the temp-file path printed by the script on stderr

Usage Examples

Example 1: Extract Full Document Text python scripts/vl_caller.py \ --file-url "https://example.com/paper.pdf" \ --pretty Then use: Top-level text for quick full-text output result[n].markdown when page-level output is needed Example 2: Extract Structured Page Data python scripts/vl_caller.py \ --file-path "./financial_report.pdf" \ --pretty Then use: result[n].prunedResult for structured parsing data (layout/content/confidence) result[n].markdown for rendered page content Example 3: Print JSON Without Saving python scripts/vl_caller.py \ --file-url "URL" \ --stdout \ --pretty Then return: Full text when user asks for full document content result[n].prunedResult and result[n].markdown when user needs complete structured page data

First-Time Configuration

• When API is not configured:
• The error will show:
• CONFIG_ERROR: PADDLEOCR_DOC_PARSING_API_URL not configured. Get your API at: https://paddleocr.com
• Configuration workflow:
• Show the exact error message to the user (including the URL).
• Guide the user to configure securely:
• Recommend configuring through the host application's standard method (e.g., settings file, environment variable UI) rather than pasting credentials in chat.
• List the required environment variables:
• PADDLEOCR_DOC_PARSING_API_URL
• PADDLEOCR_ACCESS_TOKEN
• Optional: PADDLEOCR_DOC_PARSING_TIMEOUT
• If the user provides credentials in chat anyway (accept any reasonable format), for example:
• PADDLEOCR_DOC_PARSING_API_URL=https://xxx.paddleocr.com/layout-parsing, PADDLEOCR_ACCESS_TOKEN=abc123...
• Here's my API: https://xxx and token: abc123
• Copy-pasted code format
• Any other reasonable format
• Security note: Warn the user that credentials shared in chat may be stored in conversation history. Recommend setting them through the host application's configuration instead when possible.
• Then parse and validate the values:
• Extract PADDLEOCR_DOC_PARSING_API_URL (look for URLs with paddleocr.com or similar)
• Confirm PADDLEOCR_DOC_PARSING_API_URL is a full endpoint ending with /layout-parsing
• Extract PADDLEOCR_ACCESS_TOKEN (long alphanumeric string, usually 40+ chars)
• Ask the user to confirm the environment is configured.
• Retry only after confirmation:
• Once the user confirms the environment variables are available, retry the original parsing task

Handling Large Files

There is no file size limit for the API. For PDFs, the maximum is 100 pages per request. Tips for large files: Use URL for Large Local Files (Recommended) For very large local files, prefer --file-url over --file-path to avoid base64 encoding overhead: python scripts/vl_caller.py --file-url "https://your-server.com/large_file.pdf" Process Specific Pages (PDF Only) If you only need certain pages from a large PDF, extract them first: # Extract pages 1-5 python scripts/split_pdf.py large.pdf pages_1_5.pdf --pages "1-5" # Mixed ranges are supported python scripts/split_pdf.py large.pdf selected_pages.pdf --pages "1-5,8,10-12" # Then process the smaller file python scripts/vl_caller.py --file-path "pages_1_5.pdf"

Error Handling

Authentication failed (403): error: Authentication failed → Token is invalid, reconfigure with correct credentials API quota exceeded (429): error: API quota exceeded → Daily API quota exhausted, inform user to wait or upgrade Unsupported format: error: Unsupported file format → File format not supported, convert to PDF/PNG/JPG

Important Notes

The script NEVER filters content - It always returns complete data The AI agent decides what to present - Based on user's specific request All data is always available - Can be re-interpreted for different needs No information is lost - Complete document structure preserved
