nurec-index

nurec-index is a skill for Claude Code, Codex from NVIDIA/nurec-skills. It costs 93 tokens per session (4,722 once invoked), scanned B, original, Apache-2.0.

A routing guide for NVIDIA NuRec-related work. NuRec is a set of tools and workflows for reconstructing 3D scenes from sensor or video data; this guide chooses a more specific guide for the task.

In plain words
What is it for?
It is for routing tasks such as finding NVIDIA datasets, converting sensor data to NCore V4, training or rendering 3DGUT reconstructions, extracting 3D Gaussian Splat objects, and cleaning rendered frames.
Why use it?
It prevents an agent from choosing the wrong workflow when a task involves several related 3D reconstruction, data conversion, rendering, or asset-extraction steps.

About the project

NVIDIA NuRec Skills is a set of agent instructions for running neural reconstruction and rendering workflows in NVIDIA Omniverse NuRec. It targets autonomous-vehicle and robotics simulation, guiding agents across the public containers, repositories, and artifacts that make up the NuRec stack.

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

nurec-index 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 11d 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

NuRec Skills Index

A routing skill. It decides which sibling skill to read next for a NuRec / Neural Reconstruction task. Five siblings cover the full pipeline:

  • physical-ai-datasets — find an existing NVIDIA dataset.
  • ncore — convert raw sensor data into NCore V4.
  • nre — train a 3DGUT reconstruction and render novel views from NCore V4 (or a pre-trained USDZ).
  • asset-harvester — extract per-object 3D Gaussian Splat assets from sparse AV-clip views.
  • nurec-fixer — clean up artifacts in already-rendered frames.

Use this index when the user mentions NuRec / NRE / 3DGUT / USDZ / "render this clip" / "convert this bag" / "extract objects" but the right sub-skill is not yet obvious. Always read this first.

Do NOT use this index when:

  • The right sub-skill is already obvious (open it directly).
  • The task is not a NuRec task (this skill will not help).
  • Hands-on implementation steps are needed — defer to the sub-skill this index points at.

Purpose

This skill exists so an agent never has to guess which NuRec-family skill to read next. It is a hand-curated router for the five-skill NuRec family and nothing else.

Use cases this skill is built for:

  • Disambiguate a NuRec request. The user says "render this clip", "convert this bag", "fix these frames", or "extract this car" and you need to pick the one sibling skill that owns that verb.
  • Bootstrap a multi-stage pipeline. The user's goal needs two or three siblings in a fixed order (convert → train → render, dataset → render, harvest → insert, render → harmonize). This index points you at the right starting sibling and the matching workflow A–G in references/workflows.md.
  • Translate NuRec jargon for a beginner. NuRec vs NRE, USDZ vs NCore V4, 3DGUT vs 3DGRT, NRE's built-in Fixer vs the standalone DiffusionHarmonizer — see Easy mix-ups.
  • Locate a sibling skill that is not on disk. Defer to references/discovery.md instead of guessing a path.
  • Plan disk cleanup across the family. A full NuRec workflow can leave 150 GB+ behind; defer to references/teardown.md for the documented order.

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.

nurec-index is a skill published in the GitHub repository NVIDIA/nurec-skills (38 stars, last pushed 8d ago), licensed Apache-2.0. It adds 93 tokens to every session and 4,722 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
