## What it does

This skill converts training and evaluation goals into execution graphs across existing Nemotron repository steps. It handles configs for data preparation, SFT workflows, and ModelOpt optimization. The skill creates YAML files without fabricating missing steps. If a required runner does not exist in the catalog, it flags the gap in Explorer mode.

Execution requires a local clone of the Nemotron repository with `src/nemotron/steps/` present. Commands run through `uv` from the repository root. Remote runs rely on a matching `env*.toml` profile, while hosted endpoints expect credentials such as `NVIDIA_API_KEY` exported in the shell.

The agent will not guess execution parameters. When dataset paths or GPU counts are missing, it stops with a `Blocked` status. This means you must supply concrete hardware and file details upfront. Tasks involving frontend code or web dashboards fall strictly outside its scope.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill nemotron-customize -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/nemotron-customize/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/nemotron-customize/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill nemotron-customize -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/nemotron-customize/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill nemotron-customize -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/nemotron-customize/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install NVIDIA/skills nemotron-customize
```

2. **Manually: put the files in place**
- File: `.github/skills/nemotron-customize/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill nemotron-customize -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/NVIDIA/skills --path skills/nemotron-customize
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/nemotron-customize/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill nemotron-customize -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/NVIDIA/skills/tree/HEAD/skills/nemotron-customize/SKILL.md

## When to use it
- generate valid YAML configs for Nemotron SFT and PEFT runs
- wire DAG artifact dependencies between data curation and alignment steps
- configure checkpoint evaluation commands for `eval/model_eval`
- validate environment profile settings before remote job submission

## Example prompts
- Build a DAG pipeline for Nemotron SFT using my dataset path and generate the YAML configs.
- Generate an evaluation command for `eval/model_eval` targeting my deployed endpoint.
- Check artifact compatibility between the curation output and DPO alignment step.

# nemotron-customize

IMPORTANT: Read this file before answering any `nemotron-customize`,
Nemotron customization, Curator curation, translation, SFT, PEFT, RL,
conversion, optimization, checkpoint or existing/hosted-endpoint evaluation, or
multi-step pipeline request. This applies whether the user names one step or
asks you to compose several steps into a pipeline.

Evaluation requests count even when no training is involved: "evaluate",
"benchmark", "smoke test", or "score" an existing/hosted endpoint, an API/model
ID, or a deployed model all route to `eval/model_eval`. Read this skill for
those too.

## Purpose

Turn a model-customization request into a repo-native Nemotron step pipeline.
Plan the DAG, validate artifact wiring, and create only the YAML/config files
needed to run existing steps.

Use this skill only for inspecting, configuring, validating, running, or
submitting existing Nemotron steps or multi-step training/customization
pipelines. For frontend, dashboard, visualization, generic ML advice,
billing/access, or unrelated coding tasks, stop with a short scope note and do
not inspect the step catalog or edit files in that turn.

## Prerequisites

- A checkout of the Nemotron repo with `src/nemotron/steps/` present; run from
  the repo root.
- `uv` available to invoke `uv run nemotron steps ...`.
- For remote execution: an env profile TOML (`NEMOTRON_ENV_FILE` or
  `env*.toml`) with a section matching the selected step.
- For hosted services (translation, hosted eval): the auth environment variable
  expected by the step (for example `NVIDIA_API_KEY`), exported in the
  environment — never inlined or committed.
- User-provided concrete values (model/checkpoint, data paths, output dir,
  hardware/GPU count) before any command is presented as runnable.

## Limitations
