yam-simulation-transfer

yam-simulation-transfer is a skill for Claude Code, Codex from NVlabs/ASPIRE. It costs 35 tokens per session (226 once invoked), scanned A, original, Apache-2.0.

Guidance for adapting grasping and manipulation ideas from LIBERO and robosuite, robot-learning simulation environments, to the physical YAM robot. It transfers strategies rather than simulator-specific coordinates or APIs.

In plain words
What is it for?
Use it for YAM grasping, handovers, pouring, placement, rack, or bin tasks that may benefit from approaches found in LIBERO or robosuite.
Why use it?
Simulation code can suggest useful action sequences but does not directly match a physical robot's sensors, frames, grippers, or motion planner. This guidance focuses on converting those ideas and checking them before real retries.

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 A, and why

yam-simulation-transfer 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (references/robosuite_two_arm_handover.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.

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.

What it actually says

YAM Simulation Transfer

Borrow strategy, not simulator coordinates/API/constants.

The physical-robot implementation lives in aspire/real; the source simulation workspace is its sibling aspire/sim (../sim when working from the real workspace). Inspect simulation code and agent guidance there, then convert the strategy into YAM-native behavior here.

  • references/robosuite-two-arm-handover.md
  • references/robosuite_two_arm_handover.py
  • references/drawer-libero-transfer.md

Convert ideas into YAM-native detections, frames, gripper geometry, planner previews, and artifact checks before physical retries.

Files

What ships with it

7 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.

yam-simulation-transfer is a skill published in the GitHub repository NVlabs/ASPIRE (139 stars, last pushed 8d ago), licensed Apache-2.0. It adds 35 tokens to every session and 226 once invoked, about $0.0002 per session on Opus 5. 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.
