## What is this?

Agent Skills are packaged instructions that extend AI coding agents (Claude Code, Cursor, Copilot, etc.) with domain-specific expertise. This repository provides skills for ClickHouse databases and chdb — covering schema design, query optimization, data ingestion patterns, and in-process analytics with Python.

When an agent loads these skills, it gains knowledge of ClickHouse best practices and chdb APIs, and can apply them while helping you design tables, write queries, analyze data, or troubleshoot performance issues.

Skills follow the open specification at [agentskills.io](https://agentskills.io).
