Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
5 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by VectorSpaceLab on GitHub. Read the source before you install it.

Installation

Install the Data Prep AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/VectorSpaceLab/AREX-Skill/tree/main/skills/repositories/repo-skills/adelai-det/sub-skills/data-prep
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/VectorSpaceLab/AREX-Skill.git /tmp/AREX-Skill
mkdir -p .claude/skills
cp -r /tmp/AREX-Skill/skills/repositories/repo-skills/adelai-det/sub-skills/data-prep .claude/skills/data-prep

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Data Prep in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Data Prep on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Data Prep is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

data-prep

Use this sub-skill when a task asks how to prepare datasets for AdelaiDet, register custom data, convert PIC/COCO/LVIS annotations, generate thing semantic masks, inspect mapper expectations, or create MEInst mask components.

Use this route for

Dataset directory layout and required annotation files.
COCO instance annotations, PIC person conversion, LVIS/COCO semantic masks, and thing_train2017-style outputs.
Custom dataset registration and DATASETS.TRAIN / DATASETS.TEST config overrides.
Text dataset annotation requirements before BAText/ABCNet training.
MEInst mask encoding/component prerequisites.
Visual sanity checks before training.

Do not use this route for

Environment/build/import failures. Use ../setup-build/SKILL.md.
Training command composition after data is ready. Use ../train-eval/SKILL.md.
Text lexicon/evaluator semantics. Use ../text-spotting/SKILL.md.
Demo rendering only. Use ../demo-visualize/SKILL.md.
Checkpoint or ONNX conversion. Use ../export-convert/SKILL.md.

Read first

references/dataset-preparation.md for conversion/preparation recipes.
references/data-formats.md for expected annotation shapes and config connections.
../../references/model-overview.md to map model family to data prerequisites.

Skill-owned scripts

scripts/prepare_thing_semantic.py — self-contained COCO/PIC-style thing semantic mask generator with explicit input/output paths.
scripts/gen_pic_person_coco.py — safer PIC instance/semantic masks to COCO person JSON conversion.
scripts/meinst_mask_encoding.py — helper for planning/checking MEInst mask-component generation inputs.

Typical workflow

Identify the model family and its dataset expectations.
Validate the raw dataset layout and annotation JSON.
Generate derived artifacts only when the selected config needs them.
Visualize a small sample with ../demo-visualize/scripts/visualize_dataset.py.
Return to train-eval for launch.

Decision points

If a task mentions scene text, Bezier control points, dictionaries, or lexicons, load text-spotting too.
If a config references missing thing_* semantic masks, use scripts/prepare_thing_semantic.py.
If FCPose/PIC person data is needed, use scripts/gen_pic_person_coco.py or follow the PIC layout reference.
If MEInst asks for components/PCA artifacts, use the MEInst notes before training.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Data Prep AI skill do?

Guides AdelaiDet COCO/PIC/LVIS/text dataset layout, semantic-mask generation, dataset registration, mapper expectations, and MEInst mask components.

Why use Data Prep on TypingMind?

Because you install it once and use it with any model. Data Prep is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Data Prep in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/VectorSpaceLab/AREX-Skill/tree/main/skills/repositories/repo-skills/adelai-det/sub-skills/data-prep. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Data Prep?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Data Prep?

As many as you like. As long as a model supports skills, you can use Data Prep with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Data Prep AI skill free?

Yes. It is published on GitHub by VectorSpaceLab under the NOASSERTION license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
