lerobot

lerobot is a skill for Claude Code, Codex from robium-ai/robium. It costs 162 tokens per session (6,708 once invoked), scanned B, a copy of lerobot, MIT.

A guide to Hugging Face LeRobot, a library for teaching robots physical actions from recorded demonstrations and evaluating those actions in simulation.

In plain words
What is it for?
Use it to record or load robot-arm demonstrations, train imitation-learning policies, test them in simulation, or control a robot remotely.
Why use it?
It brings the robot dataset format, training process, simulation, and teleoperation steps into one workflow.

Token cost

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.

Security

Grade B, and why

lerobot scanned grade B with 1 finding 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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (examples/load-dataset-snippet.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

lerobot

The manipulation-vertical core tool skill for robium: the LeRobotDataset format, loading and recording episodes, training imitation-learning and VLA policies (ACT, Diffusion, Pi0/Pi0.5/SmolVLA and others), evaluating in simulation, and teleoperation. LeRobot (huggingface/lerobot, PyPI package lerobot, version 0.6.0 as of 2026-07-12 (PyPI-verified; re-check: this number goes stale fast), requires-python >=3.12) is HuggingFace's end-to-end robot-learning library; this skill embeds the robotics-specific glue (dataset shape, training/eval CLI, sim envs, teleoperation) and delegates hub mechanics (auth, upload/download, model cards) to the huggingface skill's territory. LeRobot moves fast; every command below is either a direct upstream docstring/doc example fetched on 2026-07-10 or marked with how it was verified; re-check before relying on exact flags in a real project.

When to use this skill

  • Any manipulation/imitation-learning task: loading or recording a LeRobotDataset, training a policy (ACT, Diffusion, Pi0-family, SmolVLA, ...), evaluating a policy in simulation, teleoperating a robot arm.
  • The trigger phrases in the description: 'lerobot', 'manipulation policy', 'imitation learning', 'train a robot arm policy', 'ACT', 'diffusion policy'.
  • Cross-references: go to the sibling skill instead when the question is:
    • Hub auth, dataset/model upload-download, model cards, repo management → the huggingface skill's territory; LeRobot's own hf auth login/ hf upload commands are shown here only where a lerobot workflow requires them inline.
    • Whether to use uv or Docker, GPU passthrough, headless/remote display → environments (load first if not already decided; see Key directives).
    • Deciding which dataset(s) to source or combine for a task → the data umbrella skill's territory.
    • Rendering/inspecting recorded episodes in depth → the rerun skill; LeRobot's own --viz extra and lerobot-dataset-viz script wrap Rerun directly, cross-referenced here by name, not re-taught.
    • Classical motion planning (no learned policy) → out of scope repo-wide; this skill and the manipulation vertical are learning-based only.
    • The NVIDIA Isaac Lab RL stack (GPU-parallel RL/IL training environments, prebuilt tasks, policy export) → isaac-lab.
    • The whole-stack decision this feeds into → architect (routes here).

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

lerobot is a skill published in the GitHub repository robium-ai/robium (9 stars, last pushed 7d ago), licensed MIT. It adds 162 tokens to every session and 6,708 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). It is 97% identical to lerobot, differing in 104 lines, and is treated as a copy.
