conn-tool SKILL.md skillA

conn-tool 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/conn-tool@git:20261023.f74c2bd

Pins git:20261023.f74c2bd in mdr.lock. Pin the fingerprint instead.

Use this skill whenever the user wants to perform advanced functional connectivity (ROI-to-ROI, seed-to-voxel, ICA) or effective connectivity (PPI, gPPI, DCM) analysis using the CONN Toolbox. Triggers include: 'conn', 'CONN toolbox', 'functional connectivity', 'effective connectivity', 'ROI-to-ROI', 'seed-to-voxel', 'PPI', 'gPPI', 'DCM', 'psychophysiological interaction', or any request for connectivity analysis after preprocessing.

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

# CONN Tool

## Overview

CONN is a MATLAB/SPM-based toolbox for comprehensive functional and effective connectivity analysis. It excels at ROI-to-ROI, seed-to-voxel, ICA-based network analysis, and psychophysiological interaction (PPI/gPPI) as well as Dynamic Causal Modeling (DCM).

This skill serves as the **NeuroRuntime interface-layer wrapper** for the CONN Toolbox and strictly follows the hierarchical design:

1. Check whether CONN Toolbox and dependencies (MATLAB + SPM) are installed.
2. If missing → invoke `dependency-planner` to generate a safe installation plan.
3. Verify input data (typically preprocessed BOLD from `fmriprep-tool` or `hcppipeline-tool`).
4. Generate a clear, numbered execution plan with exact commands, project setup, and analysis steps.
5. Present the plan and wait for explicit user confirmation (“YES” / “execute” / “proceed”).
6. On confirmation → delegate the entire CONN project setup and analysis to `claw-shell`.
7. After completion, summarize connectivity matrices, statistical maps, and suggest next steps (e.g., visualization or `paper-writing`).

**Research use only.**

How to install

The exact contents, by fingerprint

mdr add cuhk-aim-group/neurodiscovery/conn-tool@sha256:56ceea398afe3fbf

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.
