This is a static analysis tool that parses your codebase once and generates a compressed context map so Claude, Cursor, or Copilot can understand your project structure without burning thousands of tokens on file exploration. It extracts routes, database models, components, and dependencies using AST parsing for TypeScript and regex for 13 other languages, then outputs either a single CODESIGHT.md file or a wiki-style knowledge base split by domain. The MCP server mode is the interesting part: it gives Claude Code 13 direct tools to query your codebase on demand instead of dumping everything into context. Most useful at session start or before refactoring shared files, where the blast radius command shows you exactly what breaks if you touch a specific module.
