What it does
PDF is an agent skill from flonat/flonat-research. Read, create, combine, split, rotate, OCR, watermark, secure, or extract content from PDF files. Use when a PDF is a primary input or requested output. Not for LaTeX source editing or Word and spreadsheet deliverables.
Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including scripts and reference files (for example `forms.md`, `reference.md` and `references/pdf-recipes.md`).
It sits in Documents & Office, covering PDF, LaTeX and Excel spreadsheets. It works with LaTeX and pypdf. The repository describes itself as: Shareable Claude Code + Codex infrastructure for PhD researchers — skills, agents, hooks, and rules for academic workflows.
When your agent uses it
- A PDF is a primary input
- Requested output
Example prompts
- “/pdf”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Bash(uv*, pdftotext*, qpdf*, pdftk*, mkdir*, ls*), Read, Write
What it can do on your machine
Read from SKILL.md and the folder at commit da27600. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash(uv*pdftotext*qpdf*pdftk*mkdir*ls*)ReadWrite
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 8 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
qpdf
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
PDF loads about 488 tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 157 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Its licence (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 157 words (~488 tokens).
“This guide covers essential PDF processing operations using Python libraries and command-line tools. For advanced features, JavaScript libraries, and detailed examples, see REFERENCE.md. If you need to fill out a PDF form, read FORMS.md and follow its instructions.”

When should I use PDF?
PDF fits situations like: A PDF is a primary input; requested output.
How do I install PDF in Claude Code?
Run `npx skills add flonat/flonat-research --skill pdf -a claude-code`. Or copy the skill folder (skills/pdf in flonat/flonat-research) into .claude/skills/pdf in your project. Claude Code loads it when a task matches its description.
How do I install PDF in Codex?
Run `npx skills add flonat/flonat-research --skill pdf -a codex`. Or copy the skill folder (skills/pdf in flonat/flonat-research) into .agents/skills/pdf in your project. Codex loads it when a task matches its description.
Can I use PDF in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add flonat/flonat-research --skill pdf -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/pdf, .gemini/skills/pdf, .github/skills/pdf and .opencode/skills/pdf in your project.
What does PDF need to run?
Going by SKILL.md and its folder, PDF needs Python for the scripts in its folder and the command-line tools its instructions call (qpdf). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Bash(uv*, pdftotext*, qpdf*, pdftk*, mkdir*, ls*), Read, Write.
Does PDF access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is PDF safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does PDF use?
PDF carries a proprietary licence (declared in SKILL.md). It is published on GitHub, but it is not open source: read the licence file before using or sharing it.
How many tokens does PDF use?
About 488 tokens (SKILL.md is roughly 2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.6k tokens, read only when the agent opens those files.
What are the alternatives to PDF?
Skills that share tags, products or a category with PDF: Mineru (Nebutra/MinerU-Skill, 122 stars), Scientific Report PDF (lamm-mit/scienceclaw, 244 stars), Lov Any2pdf (lovstudio/any2pdf, 211 stars) and Mineru (Nebutra/MinerU-Skill, 122 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
