retargeting

retargeting is a skill for Claude Code, Codex from nebius/nebius-physical-ai. It costs 38 tokens per session (362 once invoked), scanned A, original, Apache-2.0.

A workflow for converting already-retargeted robot-motion files into the PKL format used by SONIC locomotion training. Retargeting adapts motion made for one skeleton or robot to another.

In plain words
What is it for?
Use it to run, monitor, list, and inspect retargeting jobs, with motion inputs and outputs stored in S3. Raw BVH files need an external retargeter first.
Why use it?
It prevents training jobs from receiving the wrong file format or incomplete placeholder outputs.

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

retargeting 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 2d 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.

What it actually says

Retargeting

Retargeting converts already-retargeted SOMA/G1/Bones motion artifacts into the real motion-lib PKL schema consumed by SONIC locomotion training.

Interfaces

CLI:

npa workbench sonic retargeting run
npa workbench sonic retargeting workflow
npa workbench sonic retargeting status
npa workbench sonic retargeting list

SkyPilot YAML:

  • workflows/testing/retargeting.yaml
  • workflows/testing/sonic-locomotion-finetuning.yaml

Routing And Data Flow

Retargeting is CPU-only by default.

Inputs and outputs use S3 paths:

  • --input-path: source motion prefix or object.
  • --output-path: retargeted motion output prefix.
  • --retarget-map: optional map artifact.

The result artifacts are real .pkl motion-lib files plus retargeting_result.json metadata. Do not replace this with a manifest-only shim.

Raw BVH inputs can be converted to upstream SONIC SOMA skeleton PKLs with extract_soma_joints_from_bvh.py, but upstream SONIC does not bundle a raw BVH-to-G1 robot retargeter. Use external SOMA Retargeter/GMR before the final SONIC motion-lib conversion when starting from raw BVH.

Workflow Constraint

Keep orchestration logic in SkyPilot YAML. Do not add a Python runner script for the SONIC locomotion fine-tuning path.

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.

retargeting is a skill published in the GitHub repository nebius/nebius-physical-ai (27 stars, last pushed today), licensed Apache-2.0. It adds 38 tokens to every session and 362 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.
