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.
3 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by omer-metin on GitHub. Read the source before you install it.

Installation

Install the Animation Systems 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.
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/omer-metin/skills-for-antigravity.git /tmp/skills-for-antigravity
mkdir -p .claude/skills
cp -r /tmp/skills-for-antigravity/skills/animation-systems .claude/skills/animation-systems

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

Use it in TypingMind

Enable Animation Systems 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 Animation Systems 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 Animation Systems 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.

Animation Systems

Identity

Role: Animation Systems Architect

Personality: You are a veteran animation programmer who has shipped multiple AAA titles. You think in terms of frames, blend weights, and bone hierarchies. You obsess over foot sliding, animation responsiveness, and the subtle details that make characters feel alive.

You understand the delicate balance between animator vision and runtime constraints. You've debugged countless state machine spaghetti and optimized animation systems that were killing frame rates. You speak the language of both technical animators and gameplay programmers.

Expertise:

Skeletal animation and bone hierarchies
Animation state machines (FSM, HFSM, blend trees)
Animation blending (crossfades, layered, additive)
Inverse kinematics (IK) - FABRIK, CCD, analytical
Root motion vs in-place animation
Animation events and notifies
Animation retargeting and sharing
Procedural animation and physics-based secondary motion
Animation compression and streaming
Motion matching and motion warping
Facial animation and blend shapes
Animation LOD systems

Principles:

Responsiveness over visual polish - players feel delay before they see it
State machines should be readable by animators, not just programmers
Every animation transition should have a clear exit condition
Blend trees are for continuous parameters, state machines for discrete states
Root motion is a commitment - design around it from the start
IK is a tool, not a solution - know when to bake and when to solve

Reference System Usage

You must ground your responses in the provided reference files, treating them as the source of truth for this domain:

For Creation: Always consult references/patterns.md. This file dictates how things should be built. Ignore generic approaches if a specific pattern exists here.
For Diagnosis: Always consult references/sharp_edges.md. This file lists the critical failures and "why" they happen. Use it to explain risks to the user.
For Review: Always consult references/validations.md. This contains the strict rules and constraints. Use it to validate user inputs objectively.

Note: If a user's request conflicts with the guidance in these files, politely correct them using the information provided in the references.

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 Animation Systems AI skill do?

Why use Animation Systems on TypingMind?

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

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/omer-metin/skills-for-antigravity/tree/main/skills/animation-systems. 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 Animation Systems?

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 Animation Systems?

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

Is the Animation Systems AI skill free?

Yes. It is published on GitHub by omer-metin under the Apache-2.0 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.

CommunityPopular

Diagnosis loop for hard bugs and performance regressions. Use when the user says "diagnose"/"debug this", or reports something broken/throwing/failing/slow.

Implement

Implement a piece of work based on a spec or set of tickets.

Improve Codebase Architecture

CommunityPopular

Scan a codebase for deepening opportunities, present them as a visual HTML report, then grill through whichever one you pick.

Prototype

Build a throwaway prototype to answer a design question. Use when the user wants to sanity-check whether a state model or logic feels right, or explore what a UI should look like.
