motion-pipeline SKILL.md skillA
motion-pipeline from notque/vexjoy-agent is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add notque/vexjoy-agent/motion-pipeline@git:20260919.28d30f9Pins git:20260919.28d30f9 in mdr.lock. Pin the fingerprint instead.

CPU-only motion data processing pipeline for game animation: BVH import, contact detection, root decomposition, motion blending, FABRIK IK. No GPU required.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Motion Pipeline Skill
CPU-only motion data processing pipeline for game animation, inspired by Meta's
ai4animationpy framework (CC BY-NC 4.0). All operations run on numpy and scipy
with no GPU or PyTorch required.
## Why standalone implementations?
ai4animationpy's `Math/Tensor.py` imports `torch` unconditionally at the top
level, which propagates through every module (Animation, Import, IK, Math).
This means zero ai4animationpy modules are importable without PyTorch installed.
The standalone implementations in `scripts/motion-pipeline.py` replicate the
key algorithms from their source code using only numpy + scipy.
## Environment setup
```bash
# Create venv (one-time)
python3 -m venv /home/feedgen/vexjoy-agent/motion-pipeline-env/
# Install CPU-only deps
motion-pipeline-env/bin/pip install numpy scipy pygltflib Pillow
# Verify
motion-pipeline-env/bin/python -c "import numpy; import scipy; import pygltflib; print('OK')"
```
The venv is gitignored. The skill documents setup; it does not commit the venv.
## Commands
All commands output JSON to stdout. Errors go to stderr with exit code 1.
### import-bvh
Parse a BVH mocap file and print a motion summary.
```bash

How to install
mdr add notque/vexjoy-agent/motion-pipeline@sha256:34fa2ab7d3a00909The line at the top of this page pins the label git:20260919.28d30f9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
