Repo Prompt: AI Code Context Builder for Efficient Project Understanding
By
Chris Messina
Yesterday's bagel. Skim it, don't savour it.
Summary
Repo Prompt is a tool that helps AI models understand codebases efficiently by analyzing projects and selecting only relevant files and functions to build dense context that fits within model token limits. It works with existing AI subscriptions like Claude MAX, ChatGPT Plus, and Gemini without additional API costs, and includes an MCP server that enables context analysis and discovery for development tools like Claude Code, Cursor, and Codex.
