seed-iv-skill

seed-iv-skill is a skill for Claude Code, Codex from CUHK-AIM-Group/NeuroClaw. It costs 90 tokens per session (1,697 once invoked), scanned A, original, MIT.

A guided workflow for working with the SEED-IV dataset, a research collection of EEG recordings labelled with four emotions. It covers data checks, signal preparation, feature extraction, and emotion classification.

In plain words
What is it for?
Use it to validate SEED-IV files, preprocess EEG signals, extract measurable features, and build emotion-recognition analyses.
Why use it?
It organises the steps needed to turn raw emotion-related EEG recordings into analysis results and requires confirmation before processing starts.

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

seed-iv-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.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/classify_seed_iv.py, scripts/extract_seed_iv_features.py, scripts/validate_seed_iv.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.

SEED-IV Skill (Dataset-Orchestration Layer)

Overview

seed-iv-skill is the NeuroClaw orchestration skill for the SEED-IV (SJTU Emotion EEG Dataset - 4 emotions) dataset, developed by the BCMI Lab at Shanghai Jiao Tong University.

It strictly follows the NeuroClaw hierarchical design principles:

  • This skill only describes WHAT needs to be done and which tool skill to delegate to.
  • It contains no implementation code or concrete commands.
  • All concrete execution is delegated to existing base/tool skills via claw-shell.
  • Companion scripts in scripts/ provide reference implementations for EEG validation, feature extraction, and classification.

Core workflow (never bypassed):

  1. Identify input SEED-IV data and target analysis.
  2. Generate a numbered execution plan clearly stating WHAT needs to be done and which tool skill will handle each step.
  3. Present the full plan, estimated runtime, resource requirements, and risks to the user and wait for explicit confirmation ("YES" / "execute" / "proceed").
  4. On confirmation, delegate every step to the appropriate skill via claw-shell.
  5. After execution, save all outputs in a clean directory structure (seed_iv_output/).

Research use only.

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.

seed-iv-skill is a skill published in the GitHub repository CUHK-AIM-Group/NeuroClaw (85 stars, last pushed 6d ago), licensed MIT. It adds 90 tokens to every session and 1,697 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.
