🚨Breaking: Someone just open sourced a knowledge graph engine for your codebase and it's terrifying how good it is.
It's called GitNexus. And it's not a documentation tool.
It's a full code intelligence layer that maps every dependency, call chain, and execution flow in your repo -- then plugs directly into Claude Code, Cursor, and Windsurf via MCP.
Here's what this thing does autonomously:
→ Indexes your entire codebase into a graph with Tree-sitter AST parsing
→ Maps every function call, import, class inheritance, and interface
→ Groups related code into functional clusters with cohesion scores
→ Traces execution flows from entry points through full call chains
→ Runs blast radius analysis before you change a single line
→ Detects which processes break when you touch a specific function
→ Renames symbols across 5+ files in one coordinated operation
→ Generates a full codebase wiki from the knowledge graph automatically
Here's the wildest part:
Your AI agent edits UserService.validate().
It doesn't know 47 functions depend on its return type.
Breaking changes ship.
GitNexus pre-computes the entire dependency structure at index time -- so when Claude Code asks "what depends on this?", it gets a complete answer in 1 query instead of 10.
Smaller models get full architectural clarity. Even GPT-4o-mini stops breaking call chains.
One command to set it up:
`npx gitnexus analyze`
That's it. MCP registers automatically. Claude Code hooks install themselves.
Your AI agent has been coding blind. This fixes that.
