corr-insight

corr-insight is a skill for Claude Code, Codex from serejaris/kimi-skills. It costs 73 tokens per session (1,408 once invoked), scanned A, original, MIT.

A data-analysis tool that measures how strongly columns in a table move together. Pearson and Spearman correlation measure different kinds of relationships, while partial correlation checks whether a relationship remains after accounting for other columns.

In plain words
What is it for?
Use it to analyze CSV files, create correlation matrices, compare Pearson and Spearman results, and flag possible false correlations.
Why use it?
It helps distinguish a genuine association from a misleading one caused by another variable. It also provides significance values and plain-language explanations.

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

corr-insight 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/correlation_explorer.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.

correlation-explorer

相关性分析工具 —— 对表格数据计算 Pearson/Spearman 相关矩阵、偏相关矩阵,并自动识别疑似伪相关(由混淆变量导致的虚假关联)。

能力概览

功能 说明
Pearson 相关矩阵 线性相关系数 + p 值,适用于连续且近似正态的变量
Spearman 相关矩阵 秩相关系数 + p 值,适用于非线性单调关系或有序变量
偏相关矩阵 控制所有其他变量后的净相关(精度矩阵法),揭示变量间的直接关联
伪相关识别 自动对比简单相关与偏相关,标记因混淆变量导致的虚假显著相关
通俗解读 用中文对每对变量的相关强度、显著性、偏相关变化给出说明

Quick Start

# 分析所有数值列的相关性
python3 scripts/correlation_explorer.py data.csv

# 只分析指定列
python3 scripts/correlation_explorer.py data.csv -f "age,income,spending,score"

# 只算 Pearson
python3 scripts/correlation_explorer.py data.csv -m pearson

# 保存结果到 JSON
python3 scripts/correlation_explorer.py data.csv -o result.json

详细用法

基本调用

python3 scripts/correlation_explorer.py <数据文件> [选项]

选择相关系数类型

# 同时计算 Pearson 和 Spearman(默认)
python3 scripts/correlation_explorer.py data.csv -m all

# 只计算 Pearson
python3 scripts/correlation_explorer.py data.csv -m pearson

# 只计算 Spearman
python3 scripts/correlation_explorer.py data.csv -m spearman

调整伪相关检测灵敏度

# 更严格:相关系数下降 30% 即报警
python3 scripts/correlation_explorer.py data.csv -d 0.3

# 更宽松:下降 70% 才报警
python3 scripts/correlation_explorer.py data.csv -d 0.7

# 使用 0.01 显著性水平
python3 scripts/correlation_explorer.py data.csv -a 0.01

参数说明

参数 缩写 必填 默认值 说明
input 输入文件路径(CSV/TSV/Excel/JSON)
--features -f 全部数值列 要分析的列名,逗号分隔
--method -m all 相关系数类型:all / pearson / spearman
--alpha -a 0.05 显著性水平
--drop-threshold -d 0.5 伪相关判定的下降阈值(0~1,默认 50%)
--output -o 标准输出 结果 JSON 保存路径

What ships with it

2 files 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.

corr-insight is a skill published in the GitHub repository serejaris/kimi-skills (6 stars, last pushed 1mo ago), licensed MIT. It adds 73 tokens to every session and 1,408 once invoked, about $0.0004 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 2026-08-31.
