What it does

PDF is an agent skill from jjyaoao/HelloAgents. Comprehensive PDF manipulation toolkit for extracting text and tables, creating new PDFs, merging/splitting documents, and handling forms. When GLM needs to fill in a PDF form or programmatically process, generate, or analyze PDF documents at scale.

Its SKILL.md is about 14k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including scripts (for example `forms.md`, `reference.md` and `scripts/add_zai_metadata.py`).

It sits in Documents & Office, covering PDF. The repository describes itself as: A agent framework based on the tutorial hello-agents.

What it can do on your machine

Read from SKILL.md and the folder at commit c597a7c. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 10 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- python
- qpdf
- pdftotext
- python3
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 14k tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 3,354 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~63
When it runs · the whole SKILL.md, loaded when a task matches: ~14k

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: warnings

The automated check found patterns that need a careful read before installing.

WarningTells the agent its actions are pre-authorized / not to stop for confirmationSKILL.md:639
```
This is AUTOMATIC - do not wait for user confirmation
```

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 3,354 words (~14,154 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.”

Questions about PDF

What does PDF do?

Comprehensive PDF manipulation toolkit for extracting text and tables, creating new PDFs, merging/splitting documents, and handling forms. PDF is an agent skill from jjyaoao/HelloAgents. Comprehensive PDF manipulation toolkit for extracting text and tables, creating new PDFs, merging/splitting documents, and handling forms.

When should I use PDF?

PDF fits situations like: tasks that involve PDF.

How do I install PDF in Claude Code?

Run `npx skills add jjyaoao/HelloAgents --skill pdf -a claude-code`. Or copy the skill folder (skills/pdf in jjyaoao/HelloAgents) 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 jjyaoao/HelloAgents --skill pdf -a codex`. Or copy the skill folder (skills/pdf in jjyaoao/HelloAgents) 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 jjyaoao/HelloAgents --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 (python, qpdf, pdftotext and python3). Our summary lists: Python 3.

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 flagged 1 warning(s): tells the agent its actions are pre-authorized / not to stop for confirmation. Read the flagged lines before installing; the check is not a guarantee either way. 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 14k tokens (SKILL.md is roughly 57k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to PDF?

Skills that share tags, products or a category with PDF: Markitdown (ImCa0/just-laws, 781 stars), Gzh Design (isjiamu/gzh-design-skill, 4k stars), GenOffice Document CLI (genspark-ai/genoffice, 9.2k stars) and Harness Book Best Practice (wquguru/harness-books, 3.2k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains PDF?

jjyaoao (a GitHub user) maintains it in jjyaoao/HelloAgents, which has 3,187 GitHub stars. The repository holds 11 skills in this directory. The repository was last updated on October 6, 2026.
