dwi-skill SKILL.md skillB

dwi-skill from cuhk-aim-group/neurodiscovery is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add cuhk-aim-group/neurodiscovery/dwi-skill@git:20260506.86420c0

Pins git:20260506.86420c0 in mdr.lock. Pin the fingerprint instead.

Use this skill whenever the user wants to preprocess diffusion MRI / DWI data, compute diffusion metrics (FA/MD/AD/RD, etc.), extract ROI-wise diffusion features, or run tractography/connectome-related workflows. Triggers include: 'DWI', 'DTI', 'diffusion MRI', 'FA', 'MD', 'AD', 'RD', 'eddy', 'topup', 'QSIPrep', 'tractography', 'connectome', 'TBSS', 'white matter microstructure'. This is the NeuroClaw modality-layer interface: it plans WHAT to do and delegates execution to tool skills.

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

# DWI Skill (Modality Layer)

## Overview
`dwi-skill` is the NeuroClaw **modality-layer** interface skill responsible for diffusion MRI (DWI/DTI) preprocessing and feature extraction.

It strictly follows NeuroClaw hierarchical design principles:
- This skill defines **WHAT needs to be done** and **which tool skill to delegate to**.
- It contains **no implementation code** and **no concrete shell commands**.
- All concrete execution is delegated to tool skills and routed through `claw-shell`.- Reference implementations (MATLAB, Python) are provided for user understanding but should be wrapped via tool skills in production workflows.
**Core workflow (never bypassed):**
1. Identify input type (DICOM / NIfTI / BIDS), single-shell vs multi-shell, reverse phase-encoded b0/fieldmaps availability.
2. Generate a **numbered execution plan** (steps, tools, outputs, runtime, risks).
3. Present the plan and wait for explicit user confirmation (“YES” / “execute” / “proceed”).
4. On confirmation, delegate each step to the relevant tool skill via `claw-shell`.
5. Save outputs into `dwi_output/`.

How to install

The exact contents, by fingerprint

mdr add cuhk-aim-group/neurodiscovery/dwi-skill@sha256:13ccfa76ed2db0fd

The line at the top of this page pins the label git:20260506.86420c0, 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.
