## What it does

The skill chooses a format and its options, runs `tao-daft validate` against a local dataset or directory tree, then explains the outcome. The format is a positional argument; the dataset location goes after `--path`. Check `--help` for supported formats and their flags, since the available choices depend on the installed version.

You need Python 3.10+, the `nvidia-tao-daft` package, and DAFT data on local disk. A directory with `meta.json` beside `media/` and `text/` points to `cosmos-reason-v1.0`; a `contextual/` directory is a marker for `metropolis-v3.0`. Without either marker, the skill asks rather than guessing.

This skill handles DAFT only, not COCO, YOLO, or Data Factory JSONL. It covers `validate`, not `tao-daft info` or `tao-daft convert`. For CI, `--strict` turns warnings into failures, so check that this behavior matches your pipeline.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-validate-dataset-format -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-validate-dataset-format -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-validate-dataset-format -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install NVIDIA/skills tao-validate-dataset-format
```

2. **Manually: put the files in place**
- File: `.github/skills/tao-validate-dataset-format/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-validate-dataset-format -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/NVIDIA/skills --path skills/tao-validate-dataset-format
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-validate-dataset-format -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/tao-validate-dataset-format/SKILL.md

## When to use it
- validate the structure of a DAFT dataset
- catch schema errors in TAO data
- find broken cross-references in a dataset
- identify a DAFT format from directory markers
- make CI fail when validation reports warnings

## Example prompts
- Validate the DAFT dataset in `./dataset` and explain any errors.
- Infer the format from the directory layout, then check `./data`.
- Set up DAFT validation in CI so warnings cause a failure.

# Validate a TAO DAFT Dataset

> **Standalone install?** If this session was not initialized by the TAO skill bank plugin, run the `tao-setup` skill first (host preflight, credentials, cross-skill discovery).

## Quick start

```bash
tao-daft validate <format> --path <dataset-or-parent-dir>
```

`<format>` is a positional subcommand (e.g. `metropolis-v3.0`, `cosmos-reason-v1.0`);
`--path` is required. Discover supported formats and per-format flags via
`tao-daft validate --help` and the leaf `--help` (see "CLI conventions" below).

## Preflight
```bash
python -c "import nvidia_tao_daft" 2>/dev/null || {
  echo "MISSING: tao-daft not installed. Run:"
  echo "  pip install nvidia-tao-daft"
  exit 1
}
```

## Quick Start

Discover the installed validator formats before choosing a format slug, then
run validation with the target passed through `--path`:

```bash
tao-daft --version
tao-daft validate --help
tao-daft validate <format> --help
tao-daft validate <format> --path /path/to/daft-dataset
```

## Purpose

Drive `tao-daft validate` against a DAFT dataset (or a tree of them).
The CLI is the spec; the skill picks subcommand + flags and explains
the result.

Trigger when the user mentions "TAO DAFT", "DAFT format", validating a
DAFT dataset, schema/cross-reference errors, or `tao-daft validate`.
Do **not** trigger for non-DAFT layouts (COCO, YOLO, Data Factory JSONL),
or for `tao-daft info` / `tao-daft convert` — those have their own skills.

If the user's opening is ambiguous, run a few `--help` commands first
to ground yourself, then come back and confirm the task.

## Prerequisites

- `nvidia-tao-daft` installed (`pip install nvidia-tao-daft`; the wheel
  is enough, no source repo). Confirm with `tao-daft --version`.
- A DAFT dataset, or a parent directory of them, on local disk.

## Instructions

### CLI conventions

`tao-daft` is nested argparse subcommands. Names and flags drift across
versions, so **discover the current surface from `--help`** rather than
trusting any list in this doc.

1. **Format is a positional subcommand**, not `--format`:
   `tao-daft validate <format> [flags]`. List current formats via
````
