This repository is a comprehensive knowledge base and reference implementation for Claude Code best practices, curated by Shayan Rais. It is not a standalone application but rather a living documentation and configuration library that demonstrates how to effectively use Claude Code CLI through agents, skills, commands, hooks, and workflows. The core architecture follows a Command → Agent → Skill orchestration pattern, with working examples such as a weather reporter system and a structured RPI (Research-Plan-Implement) development workflow. The repository includes reusable configuration patterns (YAML frontmatter schemas for agents and skills), a cross-platform Python hook script for lifecycle events, detailed changelogs that track drift against official Claude Code documentation, and extensive reference guides covering settings, environment variables, MCP servers, and startup flags. While primarily a documentation and reference project, it contains runnable Claude Code configurations that can be directly adopted or adapted by other projects.
