What is processing-pdfs?

A set of tools and recipes for working with PDF files, including reading text and tables, creating documents, filling forms, and changing or combining files.

Use it to extract content, process batches, handle scanned PDFs with OCR, fill forms, add watermarks, encrypt files, or merge and split documents.

It removes the need to choose and wire together separate PDF libraries for common document tasks.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 57 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 537 The whole file, excluding the scripts and references it only reads on demand.

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.

Model	Per session	Once invoked
Fable 5	$0.00057	$0.00537
Opus 5	$0.00028	$0.00269
Sonnet 5	$0.00011	$0.00107
Haiku 4.5	$0.00006	$0.00054

Security

Grade A, and why

processing-pdfs 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 2d ago.

The scan reads SKILL.md. This mod also ships 8 executable files (scripts/check_bounding_boxes_test.py, scripts/check_bounding_boxes.py, scripts/check_fillable_fields.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

PDF Processing

Essential PDF operations using Python libraries and CLI tools.

Decision Matrix

Task	Best Tool	Reference
Merge / split / metadata / rotate	pypdf	recipes.md
Extract text (layout preserved)	pdfplumber	recipes.md
Extract tables	pdfplumber	recipes.md
Create new PDF	reportlab	recipes.md
Batch CLI ops	qpdf / pdftk	recipes.md
OCR scanned PDFs	pytesseract + pdf2image	advanced.md
Add watermark / extract images / encrypt	pypdf / pdfimages	advanced.md
Fill PDF forms	pdf-lib / pypdf	FORMS.md
Advanced pypdfium2 / pdf-lib JS	—	REFERENCE.md

Quick Start

from pypdf import PdfReader
reader = PdfReader("document.pdf")
print(f"Pages: {len(reader.pages)}")
text = "".join(page.extract_text() for page in reader.pages)

Workflow

Identify task — text extraction? table? creation? form? Pick row from matrix above.
Load reference — recipes.md covers 90% of tasks; advanced.md for OCR / encrypt; FORMS.md for forms.
Implement — copy-adapt recipe; verify output.
Validate — open in a viewer or grep extracted text.

Library Selection

Library	Use for
pypdf	Merge, split, metadata, encryption, rotation
pdfplumber	Text extraction with layout, tables
reportlab	Generate PDFs programmatically
pdf2image + pytesseract	OCR scanned documents
qpdf / pdftk (CLI)	Batch ops, no Python needed

Files

What ships with it

12 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

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.
