motion-pipeline skillA
motion-pipeline is agent-read markdown (skill) from notque/vexjoy-agent: CPU-only motion data processing pipeline for game animation: BVH import, contact detection, root decomposition, motion blending, FABRIK IK. No GPU required..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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
…Read the whole file at its exact version.
How to install
mdr add notque/vexjoy-agent/motion-pipeline@git:20260919.28d30f9mdr add notque/vexjoy-agent/motion-pipeline@sha256:34fa2ab7d3a00909Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
