Data Science

Provides tool selection guidance for code analysis using rg, ast-grep, jq, Glob, Read, and Sequential Thinking. Use when analyzing .ts, .js, .py, or other source files and need to choose the right search/analysis tool, combine multiple tools for complex workflows, or handle edge cases in code refactoring. Mention 'which tool', 'search vs grep', 'ast-grep vs ripgrep', or 'combine tools' to trigger. Primary consumers are code analysis agents.

This skill should be used when the user asks to analyze BAM/SAM/CRAM alignment files from WGS/WES sequencing. Triggers include requests to extract reads from specific regions, identify insertions and deletions, calculate coverage statistics, or export read data as JSON for downstream analysis.

CRITICAL for ALL mathematical and numerical operations including arithmetic, percentages, averages, and DATE/CALENDAR calculations (day of week, date differences, time calculations). MANDATORY when user asks to calculate, compute, solve expressions, determine dates, or perform any numeric analysis.

This skill should be used when writing test cases, fixing bugs, analyzing code for potential issues, or improving test coverage for JavaScript/TypeScript applications. Use this for unit tests, integration tests, end-to-end tests, debugging runtime errors, logic bugs, performance issues, security vulnerabilities, and systematic code analysis.

Lightning-fast DataFrame library written in Rust for high-performance data manipulation and analysis. Use when user wants blazing fast data transformations, working with large datasets, lazy evaluation pipelines, or needs better performance than pandas. Ideal for ETL, data wrangling, aggregations, joins, and reading/writing CSV, Parquet, JSON files.

Check data freshness and age for DST tables in DuckDB. Use when determining if data needs refreshing or validating data currency before analysis.

Presentation creation, editing, and analysis. When Claude needs to work with presentations (.pptx files) for: (1) Creating new presentations, (2) Modifying or editing content, (3) Working with layouts, (4) Adding comments or speaker notes, or any other presentation tasks

Use when the user asks to run Codex CLI (codex exec, codex resume) or references OpenAI Codex for code analysis, refactoring, or automated editing

This skill generates an interactive infographic visualization using p5.js that read vis-network compatible JSON data. Use this skill when creating educational infographics with nodes, edges, and hover interactions where users can explore relationships between concepts. Each infographic displays shapes with labels, shows tooltips on hover, and displays detailed descriptions in a control panel below the drawing area. The nodes are placed in absolute coordinates. The output is not a responsive design.
