yolo-datasets skillA

yolo-datasets is agent-read markdown (skill) from ultralytics/skills: Use when uploading, annotating, building, converting, analyzing, or debugging datasets in Ultralytics Platform or local YOLO — Platform dataset management and Smart Annotation, data.yaml, YOLO label .txt formats, COCO/DOTA/mask conversion, auto-labeling, splits, validation, and errors like "no labels found" or mAP near 0. Covers detect, segment, semantic, depth, classify, pose, and OBB data..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Ultralytics YOLO datasets

The #1 cause of silent training failure is a malformed dataset — validate before training.

## Fastest route: prepare data in Platform

1. Open [Platform](https://platform.ultralytics.com), create a dataset under
   **Annotate**, and choose its task.
2. Upload images, videos, ZIP/TAR archives, or NDJSON. Existing YOLO labels and COCO JSON
   can be imported; cloud-storage integrations can keep supported data in place.
3. Open an image in the fullscreen editor. Use manual tools for detect, segment,
   semantic, classify, pose, or OBB. For detect, segment, semantic, and OBB, switch to
   **Smart** mode to label with SAM or predictions from a compatible official/custom YOLO
   model.
4. Review the **Classes**, **Charts**, and **Errors** tabs, fix the split, and create a
   numbered dataset version before important runs.

Platform datasets cover all seven YOLO tasks. Depth targets are imported rather than
drawn in the editor. See
[Platform Data](https://docs.ultralytics.com/platform/data) and the
[Annotation Editor](https://docs.ultralytics.com/platform/data/annotation).

How to install

Latest version
mdr add ultralytics/skills/yolo-datasets@git:20260904.9c3b8ec
Exact content
mdr add ultralytics/skills/yolo-datasets@sha256:6f2cb591af58a454

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
