  • 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.

  • 4 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by niki914 on GitHub. Read the source before you install it.

Installation

Install the Host Command Bridge 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/niki914/zafiro/tree/main/.agents/skills/host-command-bridge
  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/niki914/zafiro.git /tmp/zafiro
mkdir -p .claude/skills
cp -r /tmp/zafiro/.agents/skills/host-command-bridge .claude/skills/host-command-bridge
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Host Command Bridge 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 Host Command Bridge 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 Host Command Bridge 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.

Host Command Bridge

Delegates heavy compilation tasks or visual presentation from the Linux VM to the Mac Host.

Boundaries (MUST FOLLOW)

  • Allowed:
    • Heavy compilation or test tasks (e.g. mac-run ./gradlew assembleDebug, mac-run ./gradlew testDebugUnitTest).
    • Presenting visual files/artifacts to the user on Mac (e.g. mac-run open path/to/report.html).
  • Forbidden:
    • All routine tasks (git, file inspection, search, normal CLI commands) MUST run locally in this Lima VM. Minimize mac-run usage.
    • Strictly forbidden from reading or writing host data outside ~/.vm/.monet (~/shared).

Usage

Check if the daemon is reachable:

bash
curl -s http://host.lima.internal:9876/health

Run commands from within any project directory under ~/shared:

bash
mac-run ./gradlew assembleDebug
mac-run open doc/report.html

Daemon Troubleshooting

The Mac host runs the HTTP daemon server; the Linux VM is only a client (mac-run). If health check fails or connection is refused:

Do NOT attempt to start the server inside the Linux VM. Prompt the user to start the daemon on their Mac host:

bash
# On Mac Host (run by user):
python3 ~/.vm/mac_command_daemon.py

If setting up for the first time on Mac:

bash
# On Mac Host (run by user):
mkdir -p ~/.vm
cp ~/.vm/.monet/repo/zafiro/.agents/skills/host-command-bridge/scripts/mac_command_daemon.py ~/.vm/mac_command_daemon.py
python3 ~/.vm/mac_command_daemon.py

To ensure mac-run is available in the Linux VM:

bash
# In Linux VM:
mkdir -p ~/.local/bin
cp ~/shared/repo/zafiro/.agents/skills/host-command-bridge/scripts/mac-run ~/.local/bin/mac-run
chmod +x ~/.local/bin/mac-run

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Host Command Bridge AI skill do?

Delegate heavy compilation/testing or opening visual artifacts on the host Mac from the Linux VM. Keep all other tasks inside the VM.

Why use Host Command Bridge on TypingMind?

Because you install it once and use it with any model. Host Command Bridge 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 Host Command Bridge in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/niki914/zafiro/tree/main/.agents/skills/host-command-bridge. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Host Command Bridge?

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 Host Command Bridge?

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

Is the Host Command Bridge AI skill free?

Yes. It is published on GitHub by niki914 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.
