A PDF document skill for creating, reading, rendering, parsing, filling, merging, and splitting PDF files. PDF is a fixed-layout document format commonly used for forms, invoices, and reports.

Use it to extract text, render pages as images, read invoice fields, fill forms, add positioned text, create PDFs, and combine or separate files.

It removes the need to handle common PDF tasks with separate ad-hoc tools and supports safer form filling and document processing.

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 5.1	$0.00037	$0.01597
Opus 5	$0.00018	$0.00798
Sonnet 5	$0.00007	$0.00319
Haiku 4.5	$0.00004	$0.00160

Security

Grade A, and why

pdf 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.

The scan reads SKILL.md. This mod also ships 12 executable files (scripts/_pdf_form_runtime.mjs, scripts/_pdf_runtime.mjs, scripts/check_bounding_boxes.mjs, …), 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.

How it starts

The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PDF

Use this skill whenever the user mentions a .pdf file or asks to inspect, extract, summarize, render, or fill one.

This skill is intentionally Node/JS-only for supported workflows. Do not switch to Python, Poppler CLIs, browser tricks, local HTTP servers, mdls, strings, or ad-hoc PDF decompression unless the user explicitly asks you to debug the runtime itself.

Supported Workflows

create new PDFs with text content
extract text from PDFs
render PDF pages to PNG images
extract invoice/document fields from PDF text
inspect and fill native PDF form fields
place text into non-fillable PDFs with explicit coordinates
create validation overlays for non-fillable form coordinates
merge or split PDFs with pdf-lib

Non-Goals

The bundled skill does not guarantee:

OCR
encrypted/decrypted PDF workflows
damaged/repair-oriented PDF recovery
external CLI dependencies

If the user asks for one of those, state that it is outside the bundled Node workflow before considering anything else.

Working Rules

Assume commands run from the workspace root.
If the current turn already includes extracted PDF text in an injected <file> block, use that text directly and answer. Do not rediscover the file.
Use the bundled scripts in skills/pdf/scripts/ first.
For PDFs outside the workspace, keep the original absolute path when invoking the Node scripts from bash.
For folder discovery outside the workspace, use bash with find. Do not use glob, ad-hoc Python file discovery, or browser tools.
Use a linear workflow. Stop as soon as one step succeeds.
Use workspace-relative output paths for final PDFs you expect HybridClaw to keep, return, or attach.
Use /tmp only for temporary output when page images or other scratch intermediates are needed.
For ordinary extraction tasks, do not probe pdfinfo, pdftotext, pdftoppm, mdls, strings, qlmanage, or browser tools.
Before filling any form, read forms.md.
For advanced bundled JS patterns, read reference.md.

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.

pdf is a skill published in the GitHub repository HybridAIOne/hybridclaw (132 stars, last pushed yesterday), licensed MIT. It adds 37 tokens to every session and 1,597 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
