Data Analyzer

Data Analyzer is a skill for Claude Code, Codex from eddiebelaval/squire. It costs 19 tokens per session (3,093 once invoked), scanned A, original, MIT.

A data analysis assistant for finding patterns, unusual values, relationships, and useful conclusions in structured or unstructured data. It also supports statistical analysis and explaining findings clearly.

In plain words
What is it for?
Use it for exploratory analysis, data quality checks, statistical tests, performance analysis, research validation, and decision support.
Why use it?
It helps turn raw datasets into understandable evidence instead of requiring you to inspect every value manually.

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 →

    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.

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

Data Analyzer 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 7d 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.

Data Analyzer

Expert data analysis agent that processes structured and unstructured datasets to extract meaningful insights, identify patterns, detect anomalies, and generate data-driven recommendations. Specializes in exploratory data analysis, statistical testing, correlation analysis, and insight storytelling.

This skill applies rigorous analytical frameworks, statistical methods, and data visualization best practices to transform raw data into actionable intelligence. Perfect for business analytics, research validation, performance analysis, and decision support.

Core Workflows

Workflow 1: Exploratory Data Analysis (EDA)

Objective: Understand dataset structure, quality, and preliminary patterns

Steps:

  1. Data Profiling

    • Dataset dimensions (rows, columns)
    • Column types and formats
    • Data completeness (missing values, nulls)
    • Unique values and cardinality
    • Data ranges and distributions
    • Generate summary statistics (mean, median, mode, std dev)
  2. Data Quality Assessment

    • Missing data patterns (MCAR, MAR, MNAR)
    • Duplicate records
    • Outliers and anomalies
    • Data consistency issues
    • Format and type mismatches
    • Document data quality issues with severity ratings
  3. Univariate Analysis

    • Distribution analysis for each variable
    • Identify skewness and kurtosis
    • Detect outliers (IQR, Z-score methods)
    • Visualize distributions (histograms, box plots, density plots)
  4. Bivariate Analysis

    • Correlation analysis (Pearson, Spearman)
    • Scatter plots for continuous variables
    • Cross-tabulations for categorical variables
    • Identify strong relationships and dependencies
  5. Multivariate Analysis

    • Correlation matrices
    • Dimensionality assessment
    • Feature importance preliminary analysis
    • Cluster tendency analysis
  6. Initial Insights

    • Key patterns and trends
    • Surprising findings
    • Hypotheses for further investigation
    • Data limitations and caveats

Data Analyzer is a skill published in the GitHub repository eddiebelaval/squire (21 stars, last pushed 25d ago), licensed MIT. It adds 19 tokens to every session and 3,093 once invoked, about $0.0001 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.
