codeindex: codeindex is a dependency analyzer that builds a blast-radius impact score for every file in your repo — showing which files will break if a given file changes. It also generates a symbol index mapping every function and class to its exact file and line number, so AI tools can locate any symbol in one lookup without scanning the whole codebase. Supports 12+ languages, zero required dependencies (pure Python stdlib), and five consumption modes including CLI, MCP server, and CLAUDE.md injection.; learn-claude-code: This repository provides a hands-on tutorial to learn how modern AI agents work by building one from scratch, emphasizing the core loop of model-tool interaction. It distills complex agent concepts into simple, iterative versions, from basic Bash agents to sophisticated skill-based systems.
