Use this skill whenever the user wants an end-to-end workflow for the ABCD Study dataset, including controlled access through the NIH Brain Development Cohorts (NBDC) platform, BIDS organization, and multimodal processing of sMRI, fMRI, and dMRI. Triggers include: 'ABCD Study', 'ABCD data', 'process ABCD', 'ABCD fMRI', 'ABCD sMRI', 'ABCD diffusion', or any request to run the ABCD multimodal pipeline.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# ABCD Skill (Dataset-Orchestration Layer)

## Overview
`abcd-skill` is the NeuroRuntime orchestration skill for the **ABCD Study (Adolescent Brain Cognitive Development)** dataset.

It coordinates a fixed three-phase workflow:
1. Obtain approved ABCD data from the NBDC Data Sharing Platform.
2. Prepare and validate BIDS-style data organization for downstream processing.
3. Delegate modality pipelines to `smri-skill`, `fmri-skill`, and `dwi-skill`.

It also provides **phenotype extraction** and **QC integration** paths:
- Extract and merge ABCD phenotype tables (mental health, cognition, substance use, etc.).
- Generate per-subject QC summaries with exclusion lists.

This skill follows NeuroRuntime hierarchy:
- Defines **WHAT to do**, not low-level implementation details.
- Does **not** execute direct shell commands itself.
- Delegates all execution via `claw-shell` to base/tool skills.

**Research use only.**

How to install

The exact contents, by fingerprint

mdr add cuhk-aim-group/neurodiscovery/abcd-skill@sha256:cc95199888f1ead5

The line at the top of this page pins the label git:20261023.f74c2bd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
