ds-ai-coding-skills
A router document and a set of skills for using Claude Code, GitHub Copilot and Codex on data science projects, covering Python, SQL, data processing, visualization and statistical review conventions.
ds-ai-coding-skills is a collection of router documents and skills for data scientists using AI coding assistants. The same rules are provided through CLAUDE.md for Claude Code and AGENTS.md for GitHub Copilot and Codex, kept identical below a shared "Hard Rules" section and checked in continuous integration with a sync script.
Detailed skills are shared across tools, with Codex reading them through a symlink, covering Python project operations, safe data handling, SQL analysis and review, Python style, Polars dataframe work, visualization, file paths and I/O, notebook workflows, and statistical or machine-learning review. A separate family of diagnostics skills defines which chart and value a method must always produce together, so a regression is not reported without also showing its residuals.
Setup requires Python 3.11 and the uv tool, and the project is run with a single sync command.
