## What it does

The skill checks which source and target formats the installed CLI accepts, then runs `tao-daft convert` with the required options. Format names are positional arguments; `--path` and `--output` specify the input and destination. The input can be one dataset or a parent directory containing several.

You need Python 3.10+, the `nvidia-tao-daft` package, and a DAFT dataset on local disk. The skill consults the CLI help before choosing a format pair because available pairs and flags depend on the installed version. An unsupported pair fails, while incorrect conversion options can produce output that looks valid but has the wrong meaning.

The CLI performs the conversion; the skill does not reimplement it in Python. You can check the result with the separate `tao-validate-dataset-format` skill. This converter is for DAFT data only.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- convert a DAFT dataset to another supported format
- prepare DAFT data for VLM training
- convert datasets beneath a parent directory
- check valid conversion options for the installed CLI

## Example prompts
- Convert my DAFT dataset to a supported format for VLM training.
- Check which target formats this DAFT dataset can use, then convert it.
- Convert the DAFT datasets in this folder and save them to the destination I provide.

# Convert 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 convert <source-format> <target-format> --path <input> --output <output>
```

Source and target are positional subcommands; `--path` and `--output` are flags.
Discover the supported formats and per-pair flags from 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 CLI surface before choosing format slugs, then run the
leaf conversion command with explicit `--path` and `--output` flags:

```bash
tao-daft --version
tao-daft convert --help
tao-daft convert <source-format> --help
tao-daft convert <source-format> <target-format> --path /path/to/daft --output /path/to/converted
```

## Purpose

Drives `tao-daft convert` to transform a DAFT dataset (or a tree of
them) between supported formats. The CLI does the real work; the
skill picks the right source/target pair and flags, then explains the
result.

Trigger on: converting a DAFT dataset, packaging DAFT QA /
summarization / temporal tasks for VLM training, producing a
`meta.json`-style training set, or the command `tao-daft convert`. Do
**not** trigger for non-DAFT → DAFT conversion (COCO, YOLO, Data
Factory JSONL) — redirect to the upstream `nvidia-tao-daft` repo's
converter skills.

If the user opens ambiguously, run a few `--help` calls first.

## Prerequisites

- `nvidia-tao-daft` installed (wheel only, not the source repo).
  Confirm with `tao-daft --version`.
- A DAFT dataset, or a parent directory containing many, on local
  disk.

## Instructions

### CLI conventions

`tao-daft` is nested argparse subcommands. The conventions below are
stable across versions even when format names or flags change, so
**always discover the current surface from `--help`** rather than
relying on names this doc happens to mention.

1. **Source and target are both positional subcommands**, not
