Safely reclaim disk space on macOS without touching personal or agent data. Use when the user asks to free disk space, clear caches, or investigate a nearly full Mac.

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by OutThisLife on GitHub. Read the source before you install it.

Installation

Install the Free Disk Space AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/OutThisLife/brooklyn-skills/tree/main/skills/free-disk-space
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/OutThisLife/brooklyn-skills.git /tmp/brooklyn-skills
mkdir -p .claude/skills
cp -r /tmp/brooklyn-skills/skills/free-disk-space .claude/skills/free-disk-space

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Free Disk Space in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Free Disk Space on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Free Disk Space is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Free Disk Space

Investigate first. Delete only regenerable data the user has authorized.

Safety

Never inspect, delete, or modify the data of the IDE or agent you're running inside — its application-support dir, caches, globalStorage, databases, extensions, or logs — unless the user explicitly names it as a cleanup target. On macOS that lives under ~/Library/Application Support/<app>/ (e.g. .../Cursor/).
Never delete browser history, extensions, cookies, credentials, local storage, IndexedDB, bookmarks, passwords, or user-created files.
Ask before destructive cleanup such as deleting Docker images, containers, volumes, or virtual disks.

Workflow

Record current usage from the macOS data volume:

bash
df -h /System/Volumes/Data

Find the largest consumers before deleting anything. Use du, package manager diagnostics, and application-specific storage commands. Do not descend into protected agent/IDE data.
Explain what is large, whether it is regenerable, and the expected impact.
Clean only safe targets:
- contents of ~/Library/Caches/
- unused package-manager cache entries, such as pnpm store prune
- known browser model/GPU caches, never browser profile data
For sparse files such as Docker's virtual disk, report actual disk use from du, not apparent size from ls.
Record usage again and report space freed.

Do not represent the sealed / system volume as the Mac's usable data-volume capacity.

Frequently asked questions

What does the Free Disk Space AI skill do?

Safely reclaim disk space on macOS without touching personal or agent data. Use when the user asks to free disk space, clear caches, or investigate a nearly full Mac.

Why use Free Disk Space on TypingMind?

Because you install it once and use it with any model. Free Disk Space is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Free Disk Space in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/OutThisLife/brooklyn-skills/tree/main/skills/free-disk-space. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Free Disk Space?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Free Disk Space?

As many as you like. As long as a model supports skills, you can use Free Disk Space with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Free Disk Space AI skill free?

Yes. It is published on GitHub by OutThisLife under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
