Last Friday, my boss threw an 87-page product requirements document at me and said: "Extract all API endpoints into a table, give it to me by end of day."

I opened the PDF and froze.

It was a scanned document—text was embedded in images. Copy manually? That'd take until midnight.

Then I remembered: our lab has a pdf skill installed.

What Does This Skill Do?

In one sentence: let AI directly read PDF files and extract text, tables, and image information.

Two modes supported:

1. Text extraction: for text-based PDFs (copyable text)
2. OCR recognition: for scanned PDFs (text in images)

Installation and Configuration

# Install the skill
clawhub install pdf

Verify installation
openclaw skills list | grep pdf

That's it. No API keys, no extra dependencies.

Real-World Usage: Three Scenarios

Scenario 1: Extract Text from PDF

pdf --path ./product-requirements.pdf \
    --prompt "Extract all API endpoint definitions, including paths, methods, parameters"

Scenario 2: OCR for Scanned PDFs

Our lab's old contracts are all scanned. Using the pdf skill:

pdf --path ./contract-2024-scanned.pdf \
    --prompt "Identify all amounts, dates, and party names in the contract"

Test results: 87-page scanned PDF, 45 seconds, 95%+ accuracy.

Scenario 3: Batch Processing Multiple PDFs

We have 50+ technical documents to process.

Common Pitfalls and Solutions

Pitfall 1: Large File Timeout

Problem: PDFs over 200 pages timeout halfway.

Solution: Extend timeout or process page by page.

Pitfall 2: Table Extraction Format Issues

Problem: Tables extracted as plain text, rows/columns misaligned.

Solution: Specify output format in prompt: "Extract as Markdown table, preserve all rows and columns."

How SFD Lab Uses It

Our 15 Agents' daily workflow:

• Little Raccoon 🦝 (PM): Read PRD docs, extract requirement lists
• Little Octopus 🐙 (Backend): Read API docs, generate interface definitions
• Little Eagle 🦅 (Security): Audit security docs, check compliance
• Little Hedgehog 🦔 (QA): Read test reports, extract bug lists
• Little Fox 🦊 (Content): Read reference materials, extract quotes

SFD Editor's Note

Back to that 87-page requirements document from the beginning.

I used the pdf skill to extract all API endpoints in 48 seconds, organized them into a table, and sent it to my boss at 10 AM.

Boss replied: "That fast? I thought you'd be working overtime."

I said: "I have 14 AI colleagues, not just me."

Honestly, I didn't use this skill much in the first month after installation. Thought "it's just reading a PDF, I can do it manually."

Until that 87-page document last week, I realized: AI's value isn't helping you do simple things—it's turning the impossible into possible.

Manually copying 87 pages? I might've quit.
