Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.07437 |
| Opus 5.5 | $0.00000 | $0.02975 |
| Sonnet 5.5 | $0.00000 | $0.01487 |
| Haiku 4.5 | $0.00000 | $0.00744 |
Grade A, and why
motion scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 20d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 614 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Motion Generation
Reconstruct a skeleton from calibrated mesh projections and sequential VLM joint annotations, then fit joints and skin weights. Generate motion from joint-position trajectories, rhythm and contact constraints through IK; refine bone orientation against the action, then export, retarget and validate on the target mesh.
Replace <...> path placeholders with actual paths; <repo_path> denotes the repository root.
Entry point: <repo_path>/pipeline/assets_gen/gen_motion/run.py.
Operator: <repo_path>/operators/gen_motion/operator.py.
Code the agent should read before changing anything: this file, then the
module docstrings under <repo_path>/operators/gen_motion/funcs/.
Prefer Vibe Motion functions
Use <repo_path>/operators/gen_motion/funcs/vibe_motion_utils/ first; fall back to
Mixamo, MoMask or Tripo only when the topology/action is unsupported or fails QA.
- Supply explicit joint-position trajectories, named rhythm events, a rest skeleton and IK constraints. Adjust this program before choosing another source.
- Check bone lengths, ground penetration, contact speed, IK residuals and skin
weights; replay the result on the target mesh. Fix reproducible function bugs
in
vibe_motion_utilsand rerun throughGenMotionOperator. - If the topology/action is unsupported or the result still fails QA, use Mixamo/local mocap or direct generation (MoMask/Tripo). Record the fallback reason, parameters and source/licence. Do not silently replace the requested motion with another preset.
Entry points and scope
| Function | Use |
|---|---|
skeleton.fit_skeleton(mesh, config=...) |
Fit a rig using complete, explicit fitting settings |
skinning.skin_mesh(mesh, rig, config=...) |
Generate weights using explicit kernel, bone convention and smoothing settings |
motion.build_plan(skeleton, rhythm=..., program=...) |
Validate a complete trajectory program and bind named joint chains |
motion.generate_clip(plan) |
Sample positions and solve joint motion through IK |
generate_vibe_motion(config=..., mesh=...) |
Produce BVH, joints, targets, residuals and optional rig/skin/GLB artifacts |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

motion is a skill published in the GitHub repository OpenDCAI/GameFactory-3A (928 stars, last pushed 5d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 7,437 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
