## What it does

This skill guides agents through public NVIDIA Nemotron embedding and reranking retrieval recipes. It routes retrieval failures based on the exact problem: when relevant documents are absent from the candidate pool and Recall@k is low, it targets the `nemotron embed` bi-encoder flow; when candidates are retrieved but ordered poorly with low nDCG, it targets the `nemotron rerank` cross-encoder flow. It also tracks model profiles like `default` (`Nemotron-3-Embed-1B-BF16`) and `llama` (`llama-nemotron-embed-1b-v2`) to prevent mixing incompatible artifacts.

The agent relies on the local repository checkout rather than static memory to inspect CLI commands and stage configs under `src/nemotron/recipes/`. It starts with dry-run commands like `uv run nemotron <family> <stage> -c <profile> -d` before proposing actual runs. GPU execution, remote Slurm tasks, and external API requests are blocked until explicitly approved, protecting both compute resources and secrets.

Launching recipes without running `uv sync --all-extras` first is bound to fail because the CLI tools and stage dependencies will be missing. Stage 0 synthetic data generation requires `NVIDIA_API_KEY`, training stages need working CUDA drivers with sufficient VRAM, and Stage 5 deployment relies on Docker with vLLM or NIM containers.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill nemotron-retrieval-recipes -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-retrieval-recipes/SKILL.md

## When to use it
- Route retrieval failures between embedding and reranker fine-tuning
- Preview stage commands with dry runs using `nemotron run -d`
- Configure Stage 0 synthetic data generation with `NVIDIA_API_KEY`
- Plan model export to NeMo Export-Deploy or deployment with Docker and vLLM

## Example prompts
- Run $nemotron-retrieval-recipes to diagnose low nDCG in our reranker pipeline
- Generate dry-run commands for nemotron embed stage 1 using the default profile
- Check prerequisites for exporting nvidia/llama-nemotron-embed-1b-v2

# Nemotron Retrieval Recipes

Invocation: `$nemotron-retrieval-recipes`.

## Purpose

Use this skill to work with public Nemotron embedding and reranking retrieval recipes in a source checkout or installed package. Prefer the current checkout over memory, because the recipe CLI, configs, containers, and output paths are actively changing. Treat each recipe family as available only after its recipe directory and matching CLI files are present.

This is a public product skill, not contributor-only guidance. Its value over static docs is to make an agent route the user's retrieval failure to the right recipe family, reconcile docs with the current checkout, avoid accidental long-running launches, preserve secrets, and return concrete preview/execution/run-report commands.

Use it only for tasks tied to the public Nemotron `embed` or `rerank` recipe flow. If the request is unrelated retrieval theory, generic vector database selection, generic benchmark advice, or non-recipe Docker/Slurm/NIM troubleshooting, stop with a short scope note and do not inspect recipe files in that turn.

## Security Notes

Use `Bash` for repo-scoped inspection, help, dry-run, and user-approved execution commands. Do not run API, GPU, Docker, Slurm, NIM, or other long-running work unless the user explicitly asks for it. Before Stage 0 SDG for either family, confirm the user's data-governance policy permits sending corpus content to the configured inference endpoints; otherwise use an approved private or air-gapped path. Never run broad environment dumps or commands that expose secret values. Prefer dotlist overrides and config review over editing recipe defaults.

## Source Priority
