What it does
PDF Compressor is an agent skill from minicoohei/ai-agent-camp. 大きなPDFファイルを圧縮するスキル。ファイルサイズを最大98%削減。 「PDFを圧縮して」「PDFを軽くして」「ファイルサイズを小さくして」等のリクエストで発動。
Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts (for example `SKILL.en.md`, `SKILL.es.md` and `agents/openai.yaml`).
It sits in Documents & Office, covering PDF. The repository describes itself as: AI Agent Camp — non-engineer-friendly AI agent training curriculum. Lessons, skills, commands, and hooks for Claude Code, Cursor, and Codex.
When your agent uses it
- Tasks that involve PDF
Example prompts
- “/pdf-compressor”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Convert PDF pages to images at specified DPI
- Resize images to target width (maintaining aspect ratio)
- Compress as JPEG with quality setting
- Rebuild PDF from compressed images
What it can do on your machine
Read from SKILL.md and the folder at commit 048ba4c. 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 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pythonbrewapt-get
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
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 Compressor loads about 544 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 161 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 161 words (~544 tokens).
“Compress PDF files by converting pages to optimized images and rebuilding the PDF.”
