Highlights

  • Watch mode for auto-rebuild on file changes
  • Git hooks for automatic analysis on commit/checkout
  • Neo4j Cypher and Obsidian vault export formats
  • Path finding and token benchmark commands

Added

New Commands

  • TOON export format with 98% token reduction vs JSON for AI agents
  • MCP server for AI agent integration with 5 graph query tools

Added

CLI Commands

  • graphize init - Create graph database directory structure
  • graphize add <repo> - Track repositories with git commit hashes
  • graphize status - Show sources with staleness detection
  • graphize analyze - Extract AST graph from Go sources
  • graphize query - BFS/DFS traversal with depth control and edge filters
  • graphize export html - Cytoscape.js interactive visualization
  • graphize export json - Cytoscape JSON format
  • graphize export toon - Token-efficient agent output
  • graphize summary - Markdown summary for agents
  • graphize report - God nodes, communities, surprises analysis
  • graphize enhance - Prepare files for LLM semantic extraction
  • graphize merge - Merge LLM-extracted semantic edges
  • graphize serve - MCP server for AI agent integration

AST Extraction

  • Go AST extraction: packages, files, functions, methods, types, imports, calls
  • SHA256-based per-file caching
  • --no-cache flag to bypass cache
  • Cache hit/miss statistics

Analysis

  • God nodes: most connected entities (excluding file-level hubs)
  • Community detection: Louvain algorithm with cohesion scores
  • Surprising connections: cross-file, cross-community edges
  • Isolated nodes: potential documentation gaps
  • Package statistics: files, functions, types, imports per package
  • Edge confidence breakdown: EXTRACTED, INFERRED, AMBIGUOUS

Semantic Extraction

  • Edge types: inferred_depends, rationale_for, similar_to, implements_pattern, shared_concern
  • LLM output parsing and validation
  • Claude Code skill for extraction workflow

MCP Server

  • query_graph - BFS/DFS traversal from search terms
  • get_node - Node details by ID or label
  • get_neighbors - Adjacent nodes with edge info
  • get_community - List community members
  • graph_summary - Stats, god nodes, suggested questions

Analysis Insights

  • Suggested questions generation:
  • Ambiguous edges needing verification
  • Bridge nodes connecting communities
  • Inferred relationships to verify
  • Isolated nodes (documentation gaps)
  • Low cohesion communities
