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

Use this skill for the Standardized Centralized Alzheimer's and Related Dementias Neuroimaging (SCAN) cohort, including NACC access planning, approved-export inventory, DICOM/NIfTI staging, BIDS organization, phenotype linkage, and MRI/PET processing. Trigger on 'SCAN dataset', 'NACC SCAN', 'ADRC imaging', 'SCAN MRI', 'SCAN PET', or requests to process a local SCAN export.
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
# SCAN Skill (Dataset-Orchestration Layer) ## Overview Use this skill to turn an approved SCAN export into an auditable multimodal workflow. Keep access control, identifier handling, staging, phenotype linkage, and modality processing explicit. SCAN means **Standardized Centralized Alzheimer's and Related Dementias Neuroimaging**. It combines standardized MRI and PET from Alzheimer's Disease Research Centers with longitudinal NACC clinical and cognitive data. Research use only. ## Access gate - Request SCAN data through the [NACC Quick Access File system](https://scan.naccdata.org/). - Access is free but is not anonymous: NACC records a project proposal and approves the request. - Defaced images, QC fields, imaging summaries, and analysis variables are available through the request system. Availability varies because images must complete defacing and QC before release. - Do not automate account creation, approval, or authenticated scraping. Begin execution only after the user has placed an approved export on local storage. - Never ask the user to paste credentials into commands, logs, chat, or repository files. ## Intake contract Before processing, identify: …

How to install
mdr add cuhk-aim-group/neurodiscovery/scan-skill@sha256:2e9a2625bc13889dThe line at the top of this page pins the label git:20260825.f7533a2, 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.
