Our review

This skill provides a structured workflow for processing PDF files, including text extraction, form filling, and result validation.

Strengths

  • Clear workflow with progress checklist
  • Modular scripts for analysis, extraction, and validation
  • Built-in error handling in scripts
  • Detailed dependency installation instructions

Limitations

  • Requires a Python environment with pypdf and pdfplumber libraries
  • Does not handle scanned PDFs without OCR
  • Validation is limited to checking for text presence
When to use it

When you need to automate data extraction or form filling from PDF documents.

When not to use it

For complex image-based PDFs or when a simple manual approach suffices.

# PDF Processing

## Quick start

Extract text:
```bash
python scripts/extract_text.py input.pdf > output.txt

Workflow

Copy this checklist:

Progress:
- [ ] Step 1: Analyze PDF structure
- [ ] Step 2: Extract content
- [ ] Step 3: Validate output

Step 1: Analyze PDF

python scripts/analyze.py input.pdf

Output shows page count, form fields, and structure.

Step 2: Extract content

python scripts/extract_text.py input.pdf > output.txt

Step 3: Validate

python scripts/validate.py output.txt

Fix any issues before proceeding.

## scripts/analyze.py 예시

```python

Usage:
    python analyze.py input.pdf

Output:
    - Page count
    - Form fields
    - Text/image ratio

핵심 포인트

  1. 워크플로우 체크리스트: 진행 추적
  2. 피드백 루프: 검증 → 수정 → 재검증
  3. 스크립트 문서화: Usage, Output 명시
  4. 에러 직접 처리: Claude에 떠넘기지 않기
  5. 의존성 명시: pip install 명령 포함
