  • 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 rmyndharis on GitHub. Read the source before you install it.

Installation

Install the Antigravity Skills Manager 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.
  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.
2

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/rmyndharis/antigravity-skills.git /tmp/antigravity-skills
mkdir -p .claude/skills
cp -r /tmp/antigravity-skills/skills/antigravity-skills-manager .claude/skills/antigravity-skills-manager
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Antigravity Skills Manager 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 Antigravity Skills Manager 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 Antigravity Skills Manager 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.

📦 Antigravity Skills Manager (rmyndharis/antigravity-skills)

The antigravity-skills-manager skill empowers Google Antigravity agents and users to discover, search, install, and manage over 300+ agent skills from the open-source repository rmyndharis/antigravity-skills.

Use this skill when

  • Searching or exploring available agent skills in the antigravity-skills catalog.
  • Installing a new skill into the global Antigravity configuration directory (~/.gemini/antigravity/skills/<skill_id>/).
  • Listing locally installed skills to check system capabilities.
  • Managing skill updates or auditing active agent tools.

Do not use this skill when

  • Performing general domain coding tasks that do not involve discovering or managing skills.
  • Working on tasks outside the scope of Antigravity skill management.

Instructions

  • Prefer the /skills-manager (or /skills) slash commands. They work wherever the plugin is registered and need no path resolution.
  • skills_cli.py does not sit next to this file. Installing this skill copies only SKILL.md into the skills directory; the script lives at the root of the checkout or npm package it came from — agy plugin install clones the repo, so it is at the clone root, and the npm package puts it at node_modules/@rmyndharis/antigravity-skills/skills_cli.py. Locate it before invoking it, and run it from there; python3 skills_cli.py <cmd> from this skill's own directory will not find it.
  • If neither the repo nor the npm package is on disk, use npx @rmyndharis/antigravity-skills (the ag-skills CLI) instead — it covers the same four operations.
  • Ensure skill installations save to ~/.gemini/antigravity/skills/<skill_id>/SKILL.md, or to AG_SKILLS_DIR when that is set.
  • All underlying commands must use standard Python library features (urllib.request, json, os, sys) without third-party dependencies.

Safety

  • install writes instructions that every future Antigravity session loads automatically. Confirm the skill id with the user before installing, and show them what search returned rather than picking on their behalf.
  • install replaces an existing installation of the same skill id, discarding local edits under that directory. Say so before overwriting.
  • Never install a skill id the user did not ask for, and never install one that is absent from the catalog.
  • install writes under the resolved skills directory — AG_SKILLS_DIR when set, otherwise ~/.gemini/antigravity/skills. Report the exact path back to the user rather than assuming the default.

Purpose

Provide a unified, lightweight, pure standard-library interface for managing Google Antigravity agent skills across platforms (Windows, macOS, Linux).

Available Commands & Usage

1. List Catalog Skills

Lists catalog skills with their categories and descriptions. An unfiltered listing is capped at the first 40 entries with a count of the remainder; add a filter to see a complete result set:

bash
python3 skills_cli.py list

Slash command equivalent: /skills-manager list (or /skills list)

2. Search Catalog Skills

Filters skills by matching keywords in skill id, name, description, category, tags, or triggers. Multi-word queries match skills containing every term, in any order, and results are never truncated:

bash
python3 skills_cli.py search <term>

Example:

bash
python3 skills_cli.py search flutter

Slash command equivalent: /skills-manager search flutter (or /skills search flutter)

3. Install Skill

Installs the whole skill folder into the global skills directory (~/.gemini/antigravity/skills/<skill_id>/), copying from the catalog shipped beside the script when present and downloading from GitHub otherwise. Any existing installation of the same id is replaced. Exits non-zero if some files could not be retrieved:

bash
python3 skills_cli.py install <skill_id>

Example:

bash
python3 skills_cli.py install flutter-expert

Slash command equivalent: /skills-manager install flutter-expert (or /skills install flutter-expert)

4. List Installed Skills

Inspects local ~/.gemini/antigravity/skills/ directory and lists installed skills:

bash
python3 skills_cli.py installed

Slash command equivalent: /skills-manager installed (or /skills installed)

Local Installation Storage Path

Skill files installed via this skill are placed in: ~/.gemini/antigravity/skills/<skill_id>/SKILL.md

On Windows: C:\Users\<user>\.gemini\antigravity\skills\<skill_id>\SKILL.md

Newly installed skills are automatically discovered by Google Antigravity upon session initialization or refresh.

Frequently asked questions

What does the Antigravity Skills Manager AI skill do?

Global skills manager for Google Antigravity. Explore, search, install, and manage 300+ agent skills from the rmyndharis/antigravity-skills catalog using pure stdlib CLI tools.

Why use Antigravity Skills Manager on TypingMind?

Because you install it once and use it with any model. Antigravity Skills Manager 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 Antigravity Skills Manager in TypingMind?

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

Which AI models can use Antigravity Skills Manager?

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 Antigravity Skills Manager?

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

Is the Antigravity Skills Manager AI skill free?

Yes. It is published on GitHub by rmyndharis 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.
