+name: pdf-processing
+description: Read, extract, and manipulate PDF documents
+---
+
+## When to use
+Use when the user asks to:
+- Extract text from PDF files
+- Read PDF content (full or specific pages)
+- Split or merge PDF documents
+- Extract metadata (title, author, page count)
+- Search within PDFs
+
+## Workflow
+
+### 1. Identify the PDF file
+Locate the PDF file path. Use `glob` or `ls` if needed.
+
+### 2. Extract text (full or partial)
+
+OpenClaw's `read` tool does not directly support PDF. You need to convert PDF to text first:
+
+```bash
+# Convert PDF to text using pdftotext (if available)
+exec pdftotext path/to/file.pdf -
+
+# Or use Python
+python -c "
+import pypdf; 
+reader = pypdf.PdfReader('file.pdf');
+print('\n'.join([page.extract_text() for page in reader.pages]))
+"
+```
+
+Then capture the output for processing.
+
+### 3. Parse and structure content
+- If extracting form data, organize into key-value pairs
+- If extracting tables, preserve structure (CSV/markdown table)
+- If searching, return matching snippets with page numbers
+
+### 4. For advanced operations
+- **Split PDF**: Use appropriate tool to split into separate files
+- **Merge PDFs**: Combine multiple PDFs in order
+- **Metadata**: Extract or modify PDF metadata
+
+## Tool Requirements
+This skill assumes the following tools are available:
+- `exec` (to run conversion commands: pdftotext, python, etc.)
+- `read` (for text files after conversion)
+- `write`/`edit` (for saving extracted content)
+- Optional: `poppler-utils` package (pdftotext) or `pypdf` Python library
+
+## Examples
+
+<Good>
+User: "Lấy nội dung invoice.pdf"
+Assistant:
+1. Xác định đường dẫn file
+2. Dùng read để extract text
+3. Trích xuất thông tin quan trọng (số hóa đơn, ngày, tổng tiền)
+4. Trả về dữ liệu có cấu trúc
+</Good>
+
+<Bad>
+Chỉ nói "Tôi đọc được nội dung PDF" mà không trích xuất thông tin cụ thể.
+</Bad>
+
+## Limitations
+- Large PDFs (>100 pages) may be truncated — check tool limits
+- Scanned PDFs require OCR — ensure OCR tool is available
+- Password-protected PDFs need password first
+
+## Verification Checklist
+- [ ] PDF file exists and is accessible
+- [ ] Extracted text is complete (no truncation)
+- [ ] Structured data is accurate
+- [ ] Page numbers/references are correct if cited
+- [ ] For tables, formatting is preserved
