  • 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 open-fox on GitHub. Read the source before you install it.

Installation

Install the Blob0 AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

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.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/open-fox/agents/tree/main/skills/blob0
  4. 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/open-fox/agents.git /tmp/agents
mkdir -p .claude/skills
cp -r /tmp/agents/skills/blob0 .claude/skills/blob0
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Blob0 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 Blob0 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 Blob0 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.

Blob0

Before every storage task, run the Blob0 executable below with the arguments skills print blob0, read the full output, and follow it. Quote the path literally for your shell; always pass a subcommand (no arguments opens the desktop app).

json
"/Applications/Blob0.app/Contents/MacOS/blob"

The printed instructions ship with the installed app and update with it, so read them again for each task and never replace this file with them. If the command fails, stop and ask the user to check the Blob0 install path.

Frequently asked questions

What does the Blob0 AI skill do?

Operate Cloudflare R2 or S3-compatible storage through the local Blob0 app. Use to browse, upload, download, organize, share, audit, or safely clean up storage.

Why use Blob0 on TypingMind?

Because you install it once and use it with any model. Blob0 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 Blob0 in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/open-fox/agents/tree/main/skills/blob0. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Blob0?

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 Blob0?

As many as you like. As long as a model supports skills, you can use Blob0 with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Blob0 AI skill free?

It is published on GitHub by open-fox. Check the repository for licensing terms. 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.
