A skill for working with PDF files using Qubicl's local document tools. PDF is a fixed-layout document format commonly used for forms, reports, and printable files.

Use it to create, inspect, edit, merge, split, fill, watermark, secure, render, or validate PDF files.

It provides procedures and commands for handling common PDF tasks while keeping inspection and output steps consistent. It also supports checking layout by rendering pages as images.

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	$0.00045	$0.00387
Opus 5	$0.00023	$0.00193
Sonnet 5	$0.00009	$0.00077
Haiku 4.5	$0.00005	$0.00039

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 6d ago.

The scan reads SKILL.md. This mod also ships 13 executable files (scripts/_raster.py, scripts/pdf_create.py, scripts/pdf_fill_form.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 workflows

Use Qubicl file tools to inspect inputs and save outputs under /home/qubicl. Use exec_command for the deterministic helpers bundled with this skill. Obtain this package's resourceRoot from skill_view; do not assume a client-specific skill directory.

The curated browser, computer, and workstation images provide the declared Python libraries plus Poppler. Run helpers through /opt/qubicl/skills-venv/bin/python. If a dependency is absent, report that the current preset does not support the operation; do not install packages automatically.

Common helpers beneath <resourceRoot>/scripts/:

pdf_read.py FILE --text|--tables|--meta|--fields
pdf_create.py SPEC.json -o OUTPUT.pdf
pdf_merge.py INPUT... -o OUTPUT.pdf
pdf_split.py FILE --pages 1-3,5 -o OUTPUT.pdf
pdf_page_image.py FILE --out-dir DIR
pdf_make_form.py SPEC.json -o OUTPUT.pdf
pdf_fill_form.py FILE --fields-json VALUES.json -o OUTPUT.pdf
pdf_stamp.py, pdf_watermark.py, pdf_meta.py, and pdf_secure.py

Read references/forms.md only for AcroForm work.

For inspection, extract text first and render representative pages when layout matters. Use take_screenshot only for the live desktop; use generated page images for document QA. Verify important outputs by reopening them with a read helper and, when visual fidelity matters, by rendering pages. Never overwrite the only input copy unless the user explicitly requests in-place editing.

Files

What ships with it

15 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.
