Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 33 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.01219 |
| Opus 5 | $0.00046 | $0.00609 |
| Sonnet 5 | $0.00018 | $0.00244 |
| Haiku 4.5 | $0.00009 | $0.00122 |
Grade A, and why
scan-skill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.
- 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:
- approved request or release identifier
- export root and whether images are DICOM, NIfTI, or already BIDS-like
- requested modalities and subject/session subset
- NACC clinical/UDS tables supplied with the export
- available stable identifiers and visit/date fields
- local storage, compute, and DUA restrictions
Do not assume every participant has every optional sequence. Build modality availability from the files and QC tables, not from cohort-level descriptions.

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 9d ago First seen · 115 lines · 91 tokens per session scan A 2e9a2625bc13
scan-skill is a skill published in the GitHub repository CUHK-AIM-Group/NeuroClaw (85 stars, last pushed 6d ago), licensed MIT. It adds 91 tokens to every session and 1,219 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
