What it does

Protomotions is an agent skill from VectorSpaceLab/AREX-Skill. Use this skill for ProtoMotions 3 humanoid simulation, motion-learning, retargeting, simulator-backend, training, inference, and deployment workflows.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts and reference files (for example `references/cli-and-config.md`, `references/install-and-backends.md` and `references/quick-reference.md`).

It sits in DevOps & Cloud, covering Deployment. The repository describes itself as: A Skill Library for Automated Machine Learning. The licence is Apache-2.0.

When your agent uses it

  • ProtoMotions 3 humanoid simulation
  • Motion-learning
  • Simulator-backend
  • Deployment workflows

Example prompts

  • “/protomotions”

Requirements

  • Python 3

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. ProtoMotions intentionally uses separate environments per simulator backend. Do not install all extras into one environment.
  2. IsaacGym and IsaacLab must be imported before importing torch; use protomotions.utils.simulator_imports.import_simulator_before_torch() in…
  3. The wheel/package ships Python modules and most robot assets, but examples, checkpoints, MotionLib data, and some conversion helpers are…
  4. SMPL/SMPL-H body-model assets are intentionally excluded from built distributions. Use a complete licensed asset tree and set…
  5. resolved_configs.pt and resolved_configs_inference.pt are the source of truth for trained runs; YAML sidecars are human-readable only.
  6. Cross-simulator transfer is not automatic. It is expected mainly for policies explicitly trained with transfer-oriented domain…

What it can do on your machine

Read from SKILL.md and the folder at commit ac3fe1a. 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), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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

Protomotions loads about 1.1k tokens when it runs, and up to ~6.4k if it reads all its reference files. Until then it costs about 41 tokens; SKILL.md has 397 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~6.4k

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.

ProtoMotions

Use this repo skill when a task involves ProtoMotions 3 (protomotions), a Python framework for GPU-accelerated humanoid and character simulation, motion imitation, retargeting, reinforcement-learning experiments, and G1 deployment workflows.

Fast routing

  • Install/import/backend issue: read sub-skills/installation-and-backends/SKILL.md, then references/troubleshooting.md if assets or simulator imports fail.
  • Simulator, robot, terrain, scene, or tutorial-style construction: read sub-skills/simulator-foundations/SKILL.md.
  • Training, inference, experiment configs, checkpoints, domain randomization, SLURM, or GPC/PEFT: read sub-skills/training-and-experiments/SKILL.md.
  • MotionLib, AMASS/PHUMA/SEED/Kimodo data conversion, PyRoki retargeting, contacts, FPS, or motion filters: read sub-skills/retargeting-and-motion-data/SKILL.md.
  • ONNX export, standalone MuJoCo deployment, G1 real-robot integration, custom robots, MJCF/USD, or tracker input semantics: read sub-skills/deployment-and-robots/SKILL.md.

What to know before acting

  1. ProtoMotions intentionally uses separate environments per simulator backend. Do not install all extras into one environment.
  2. IsaacGym and IsaacLab must be imported before importing torch; use protomotions.utils.simulator_imports.import_simulator_before_torch() in custom scripts.
  3. The wheel/package ships Python modules and most robot assets, but examples, checkpoints, MotionLib data, and some conversion helpers are source-checkout assets. A source checkout with Git LFS is required for packaged examples or pretrained artifacts.
  4. SMPL/SMPL-H body-model assets are intentionally excluded from built distributions. Use a complete licensed asset tree and set PROTOMOTIONS_ASSET_ROOT when those assets are missing.
  5. resolved_configs.pt and resolved_configs_inference.pt are the source of truth for trained runs; YAML sidecars are human-readable only.
  6. Cross-simulator transfer is not automatic. It is expected mainly for policies explicitly trained with transfer-oriented domain randomization, especially the documented G1 deployment tracker.

Minimal install and inspection checks

After selecting a backend environment, run:

bash
protomotions info --json
protomotions train-agent --help
protomotions inference-agent --help

For a Python smoke without starting a simulator:

python
from protomotions.robot_configs.factory import robot_config
from protomotions.simulator.factory import get_simulator_config_class
from protomotions.components.motion_lib import MotionLibConfig

print(robot_config("g1").number_of_actions)
print(get_simulator_config_class("mujoco").__name__)
print(MotionLibConfig().motion_file)

The bundled script scripts/inspect_protomotions_install.py performs the same checks and emits JSON.

Repo-level references

  • references/quick-reference.md: compact command, object, and file-artifact cheat sheet.
  • references/install-and-backends.md: backend environment choices and simulator compatibility summary.
  • references/cli-and-config.md: train/inference CLI conventions and resolved-config lifecycle.
  • references/troubleshooting.md: cross-cutting failures for imports, assets, data, checkpoints, simulator backends, and deployment.
  • references/repo-provenance.md: source commit, version, evidence paths, and verification baseline for this generated skill.
  • references/repo-routing-metadata.json: structured scenario metadata used by repo-skill import tooling.

Safety and scope boundaries

  • Treat full training, simulator rollout, PyRoki retargeting, ONNX deployment, IsaacLab conversion, and real-robot control as hardware/data-dependent operations. Prefer parser/import/config checks before long runs.
  • Do not run real-robot commands without explicit human authorization and an emergency-stop plan.
  • Do not mutate a user's existing backend environment without permission; create a separate backend-specific environment when dependencies conflict.
  • When using a package-only install, do not assume source-checkout examples or large Git LFS assets are present.
