Create Spine 2D skeletal animations from pre-existing character assets (separated body-part PNGs, atlas spritesheet, or a full character image).

- SKILL.md covers Step 0: Set Up Scripts, What You Need From the User and Full Pipeline

What it does
Spine Animation is an agent skill from GenielabsOpenSource/spine-animation-ai. Create Spine 2D skeletal animations from pre-existing character assets (separated body-part PNGs, atlas spritesheet, or a full character image). Use this skill whenever the user wants to animate a 2D character, create Spine JSON from existing art assets, rig a character with bones, build walk/idle/run/attack animations, produce an interactive Spine Web Player preview, or generate Spine-compatible export files (.json + .atlas + .png). Also trigger when the user mentions "Spine animation", "2D rigging", "skeletal…
Its SKILL.md is about 17k tokens, which your agent loads only when the skill is triggered. The skill folder holds 145 other files, including scripts and reference files (for example `.github/workflows/build-skill.yml`, `.github/workflows/pages.yml` and `CONTRIBUTING.md`).
It sits in Game Development, covering Game development and Sprites and pixel art. It works with Python. The repository describes itself as: AI-powered Claude skill for Spine 2D skeletal animation — auto-rig, animate, and preview characters.
When your agent uses it
- The user wants to animate a 2D character
- Create Spine JSON from existing art assets
- Rig a character with bones
- Build walk/idle/run/attack animations
Example prompts
- “Spine animation”
- “2D rigging”
- “skeletal animation”
- “/spine-animation”
Requirements
- Python 3
- A credential in GEMINI_API_KEY
What it can do on your machine
Read from SKILL.md and the folder at commit 702b716. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
python3pippython
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
aistudio.google.comunpkg.comen.esotericsoftware.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
GEMINI_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Spine Animation loads about 17k tokens when it runs, and up to ~18k if it reads all its reference files. Until then it costs about 215 tokens; SKILL.md has 822 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Its licence (CC-BY-NC-4.0) doesn't allow us to republish the file, so here is its outline and opening line. It has 822 words (~17,424 tokens).
