jcodemunch-mcp: jCodeMunch MCP is a highly token-efficient server that leverages tree-sitter AST parsing to provide precise GitHub source code retrieval. It drastically cuts AI token costs by allowing agents to fetch only the exact code snippets they need, rather than reading entire files.; 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.
Significantly reduce AI token costs in retrieval-heavy development workflows, especially for LLM-powered agents.
