What it does
Character Rigging is an agent skill from calesthio/OpenMontage. Build data-driven 2D character rigs for local animation: parts, pivots, layers, constraints, views, and reusable rig packages.
Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Video production. The repository describes itself as: World's first open-source, agentic video production system. 12 production pipelines, 100+ tools, 700+ agent skill and production-knowledge files. Turn your AI coding assistant… The licence is MIT.
When your agent uses it
- Tasks that involve Video production
Example prompts
- “/character-rigging”
What it can do on your machine
Read from SKILL.md and the folder at commit 9327439. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
gsap.comremotion.dev
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Character Rigging loads about 460 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 163 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); files beside SKILL.md are not scanned.

Character Rigging
Use this skill when building OpenMontage rig_plan artifacts or renderer input
for local 2D character animation.
Proven Patterns
- Keep runtime code generic; make each character a data package.
- Split characters into independently transformable parts.
- Define pivots in the same coordinate space as the artwork.
- Store constraints on moving parts to prevent impossible rotations.
- Keep layer order explicit; do not rely on SVG source order after generation.
- Start with one view and add views only when the shot list requires them.
Rig Package
{
"character_id": "mouse",
"rig_type": "svg_rig",
"parts": [
{ "id": "body", "kind": "torso", "layer": 10 },
{ "id": "head", "kind": "head", "layer": 30, "parent": "body" },
{ "id": "arm_right", "kind": "limb", "layer": 40, "parent": "body" }
],
"joints": {
"head": { "pivot": [320, 180], "rotation": [-20, 20] },
"arm_right": { "pivot": [390, 310], "rotation": [-70, 95] }
}
}Quality Checklist
- Every moving part has a pivot.
- Every child part has a parent where hierarchy matters.
- Mouth shapes are separate assets or separate path groups.
- Eyes and pupils are separate when gaze needs to change.
- Props are separate if the character touches or carries them.
Sources
- SVG transform-origin behavior is browser-defined and can be sensitive to
coordinate space; prefer explicit SVG-coordinate pivots when using GSAP
