pdf-reader

pdf-reader is a skill for Claude Code, Codex from phanghonghao/THU-Awesome-Skills. It costs 85 tokens per session (2,454 once invoked), scanned A, original, MIT.

A PDF text-extraction guide using PyMuPDF, a Python library for reading PDF files. It supports plain text, formatted HTML, and structured output containing layout details.

In plain words
What is it for?
Use it to extract text from PDFs, retain headings and tables as HTML, or collect font, position, and layout data for conversions to formats such as TeX or Word.
Why use it?
It provides a consistent way to read PDFs when the standard file-reading tool is unsuitable. Different extraction modes help preserve either simple content or document formatting.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pdf-reader scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PDF Reader Skill (PyMuPDF)

Use PyMuPDF (import fitz) to read PDF files. Supports 3 extraction modes with increasing fidelity. Handles Chinese text, multi-page PDFs, and image-based PDFs.

When to Use

  • Any time you need to read a .pdf file — always use this instead of the native Read tool
  • User mentions: "read PDF", "读取PDF", "PDF内容", "提取PDF", "PDF text", "open PDF"
  • User provides a file path ending in .pdf
  • Any task requiring PDF content extraction

Extraction Modes

Choose the mode based on the downstream task:

Mode Method Output Best for
text (default) get_text() Plain text Simple reading, summarization
html get_text("html") HTML with CSS formatting High-fidelity intermediate format, preserving bold/italic/font size/color
dict get_text("dict") Structured JSON-like dict Maximum fidelity — font name, size, color, position, flags; ideal for PDF → .tex conversion

Mode selection guide:

  • Just need to read content? → text
  • Need to preserve formatting (bold, italic, headings, tables)? → html
  • Converting PDF to .tex/.docx and need font size / layout info? → dict
  • Not sure? → Use dict (most complete, can derive everything else)

Implementation

Step 1: Check PyMuPDF Installation

python -m pip install PyMuPDF 2>&1 | tail -3

Step 2: Extract PDF Content

Always set PYTHONIOENCODING=utf-8 to avoid GBK encoding issues on Windows.


Mode: text (default — plain text extraction)
PYTHONIOENCODING=utf-8 python -c "
import fitz, sys
pdf_path = sys.argv[1]
doc = fitz.open(pdf_path)
print(f'Total pages: {len(doc)}')
for page in doc:
    text = page.get_text()
    if text.strip():
        print(f'--- Page {page.number + 1} ---')
        print(text)
    else:
        print(f'--- Page {page.number + 1}: [empty/image-only] ---')
doc.close()
" "<PDF_PATH>"

With page range:

PYTHONIOENCODING=utf-8 python -c "
import fitz, sys
pdf_path = sys.argv[1]
start, end = int(sys.argv[2]) - 1, int(sys.argv[3])
doc = fitz.open(pdf_path)
print(f'Total pages: {len(doc)}, extracting pages {start+1}-{end}')
for i in range(start, min(end, len(doc))):
    text = doc[i].get_text()
    if text.strip():
        print(f'--- Page {i + 1} ---')
        print(text)
    else:
        print(f'--- Page {i + 1}: [empty/image-only] ---')
doc.close()
" "<PDF_PATH>" "<START>" "<END>"

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
