cpm

cpm is a skill for Claude Code, Codex from CUHK-AIM-Group/NeuroClaw. It costs 60 tokens per session (660 once invoked), scanned A, original, MIT.

A Connectome Predictive Modeling workflow for predicting categories or numbers from brain connectivity data. It selects useful connections separately inside each training fold to reduce biased results.

In plain words
What is it for?
Use it for classification or regression with connectivity matrices or edge lists, labelled subjects, fold-based training, and saved model outputs.
Why use it?
It provides a repeatable way to prepare connectivity data, train models, and avoid using test-fold information during feature selection.

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

cpm 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 1 executable file (scripts/train_reference.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.

CPM Skill

Overview

cpm is the canonical NeuroClaw implementation of Connectome Predictive Modeling. Edge selection is repeated independently inside every training fold.

Task Input Output
Classification subject FC matrices/vectors class and probability
Regression subject FC matrices/vectors continuous prediction

Installation

pip install numpy pandas scipy scikit-learn joblib

Workflows

1. Prepare data

connectomes.npz:

X:          [subjects, nodes, nodes] or [subjects, edges]
subject_id: [subjects]

labels.csv contains the same subject IDs and a target column.

2. Regression

python skills/cpm/scripts/train_reference.py \
  --connectomes connectomes.npz \
  --labels labels.csv \
  --target cognitive_score \
  --subject-col subject_id \
  --task regression \
  --p-threshold 0.01 \
  --folds 5 \
  --output-dir run_models_output/cpm

3. Classification

python skills/cpm/scripts/train_reference.py \
  --connectomes connectomes.npz \
  --labels labels.csv \
  --target diagnosis \
  --task classification \
  --p-threshold 0.01 \
  --output-dir run_models_output/cpm_classification

If p-threshold is tuned, use nested validation or training-only selection.

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.

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.

cpm is a skill published in the GitHub repository CUHK-AIM-Group/NeuroClaw (84 stars, last pushed 3d ago), licensed MIT. It adds 60 tokens to every session and 660 once invoked, about $0.0003 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.
