bold5000-skill

bold5000-skill is a skill for Claude Code, Codex from CUHK-AIM-Group/NeuroClaw. It costs 103 tokens per session (1,821 once invoked), scanned A, original, MIT.

A workflow for downloading and preparing the BOLD5000 research dataset, which contains brain scans from people viewing 5,000 images. It organizes the data in BIDS, a common folder and naming standard for brain-imaging research, then passes it to structural and functional MRI processing workflows.

In plain words
What is it for?
Use it to download BOLD5000 from OpenNeuro, validate its organization, and coordinate processing of structural MRI and task-based functional MRI data.
Why use it?
It gives researchers a defined path from the original dataset to consistently organized data ready for analysis.

Token cost

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.

Security

Grade A, and why

bold5000-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 10d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/bold5000_qc_summary.py, scripts/extract_bold5000_stimulus.py, scripts/reorganize_bold5000.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

BOLD5000 Skill (Dataset-Orchestration Layer)

Overview

bold5000-skill is the NeuroClaw orchestration skill for the BOLD5000 dataset.

BOLD5000 is a high-density repeated visual fMRI dataset with 8 participants performing 5,000-image visual recognition tasks. It is designed for studying visual object recognition and scene understanding.

It coordinates a fixed three-phase workflow:

  1. Download BOLD5000 data from the OpenNeuro repository.
  2. Prepare and validate BIDS-style data organization for downstream processing.
  3. Delegate modality pipelines to smri-skill and fmri-skill.

This skill follows NeuroClaw 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.


Download Stage (Mandatory First Step)

Source

BOLD5000 data is available on OpenNeuro:

Supported BOLD5000 Data Packages

  • Imaging data: T1w structural, task-fMRI (NIfTI format)
  • Stimulus data: 5,000 natural images with category labels and image metadata
  • Behavioral data: Recognition memory judgments, response times
  • Participants: 4 participants x ~1250 images each (high-density repeated measures)

Delegation Rules for Download

  • Environment/setup checks: dependency-planner + conda-env-manager
  • OpenNeuro dataset download: claw-shell (via openneuro CLI or datalad)
  • Optional raw-data organization to BIDS-style staging: bids-organizer

Download Inputs to Confirm in Plan

  • Target subset (all subjects, specific subjects)
  • Whether to include stimulus images
  • Destination directory with sufficient disk space

Narrow Path: BOLD5000 Raw NIfTI -> BIDS Staging

Use this path when the task only asks to reorganize raw BOLD5000 NIfTI files into a BIDS-style dataset and does not require preprocessing or downstream analysis.

Changes

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.

bold5000-skill is a skill published in the GitHub repository CUHK-AIM-Group/NeuroClaw (84 stars, last pushed 4d ago), licensed MIT. It adds 103 tokens to every session and 1,821 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 2026-08-30.
