Graphify is a CLI tool and library that extracts structural and semantic knowledge graphs from source code across 36+ programming languages. It parses files using tree-sitter grammars, builds a graph of nodes (functions, classes, modules, etc.) and edges (calls, imports, inheritance, etc.), performs community detection via Leiden/Louvain, and generates reports, wikis, and exports to formats like Obsidian, Neo4j, and FalkorDB. The system integrates with AI coding assistants through an MCP server (stdio/HTTP), skill files (SKILL.md, CLAUDE.md), and git hooks for automatic graph updates. Key entry points include `graphify extract`, `graphify query`, `graphify serve`, and `graphify install`. External dependencies include tree-sitter grammars, LLM APIs (OpenAI, Anthropic, Gemini, Ollama), and optional databases. The architecture is modular: per-language extractors in `graphify/extractors/`, graph assembly in `build.py`, clustering in `cluster.py`, and export in `export.py`. The codebase demonstrates strong engineering practices with extensive tests, atomic file writes, security validation (SSRF, path traversal), and cross-platform support.
