What it does
Pillow is an agent skill from VectorSpaceLab/AREX-Skill. Use this repo skill when working with Pillow (PIL fork) image processing: opening/saving images, transforms, formats, metadata, drawing/text, fonts, and custom image plugins.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `references/installation-and-features.md`, `references/repo-provenance.md` and `references/repo-routing-metadata.json`).
It works with Python. The repository describes itself as: A Skill Library for Automated Machine Learning.
Example prompts
- “/pillow”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit ac3fe1a. 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:
python
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
Pillow loads about 1.2k tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 45 tokens; SKILL.md has 415 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 (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 415 words (~1,247 tokens).
“Use this skill when an agent needs to write, debug, or explain Pillow code for image processing in Python. Pillow imports as PIL and centers on PIL.Image.Image objects created by Image.open() or Image.new().”

Questions about Pillow
What does Pillow do?
Use this repo skill when working with Pillow (PIL fork) image processing: opening/saving images, transforms, formats, metadata, drawing/text, fonts, and custom image plugins. Pillow is an agent skill from VectorSpaceLab/AREX-Skill. Use this repo skill when working with Pillow (PIL fork) image processing: opening/saving images, transforms, formats, metadata, drawing/text, fonts, and custom image plugins.
How do I install Pillow in Claude Code?
Run `npx skills add VectorSpaceLab/AREX-Skill --skill pillow -a claude-code`. Or copy the skill folder (skills/repositories/repo-skills/pillow in VectorSpaceLab/AREX-Skill) into .claude/skills/pillow in your project. Claude Code loads it when a task matches its description.
How do I install Pillow in Codex?
Run `npx skills add VectorSpaceLab/AREX-Skill --skill pillow -a codex`. Or copy the skill folder (skills/repositories/repo-skills/pillow in VectorSpaceLab/AREX-Skill) into .agents/skills/pillow in your project. Codex loads it when a task matches its description.
Can I use Pillow 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 VectorSpaceLab/AREX-Skill --skill pillow -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/pillow, .gemini/skills/pillow, .github/skills/pillow and .opencode/skills/pillow in your project.
What does Pillow need to run?
Going by SKILL.md and its folder, Pillow needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.
Does Pillow 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 Pillow 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 Pillow use?
Pillow has a licence file (declared in SKILL.md) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Pillow use?
About 1.2k tokens (SKILL.md is roughly 5k 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 2.2k tokens, read only when the agent opens those files.
What are the alternatives to Pillow?
Skills that share tags, products or a category with Pillow: MCP Server Builder (anthropics/skills, 180k stars), PDF Processing (anthropics/skills, 180k stars), NotebookLM Research Assistant (PleasePrompto/notebooklm-skill, 7.8k stars) and Manim Video Production (browser-use/video-use, 29k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Pillow?
VectorSpaceLab (a GitHub organization) maintains it in VectorSpaceLab/AREX-Skill, which has 331 GitHub stars. The repository holds 157 skills in this directory. The repository was last updated on September 3, 2026.
