nemotron-customize

nemotron-customize is a plugin for Claude Code from NVIDIA-NeMo/Nemotron. Its manifest loads nothing; the 1 skill it bundles cost 35 tokens per session together, scanned A, original, Apache-2.0.

A set of workflows for adapting NVIDIA Nemotron models to new data and tasks. It covers cleaning and translating datasets, fine-tuning, continued pretraining, alignment, benchmarking, evaluation, checkpoint conversion, and optimization.

In plain words
What is it for?
Use it to plan or configure data preparation, training, fine-tuning, reinforcement-learning alignment, benchmark runs, model conversion, optimization, and end-to-end Nemotron pipelines.
Why use it?
It helps organize model customization around the repository’s existing steps, configurations, and environment profiles instead of assembling the process from scratch.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

nemotron-customize 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 5d 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 installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 35 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
