SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve? Understanding a large codebase's architecture is difficult when reading files one by one. This Skill indexes any git repository into a knowledge graph of symbols, call chains, and clusters, then serves an interactive web UI that can be shared remotely through a Cloudflare tunnel. ## Core Features & Use Cases - Codebase Indexing: Runs GitNexus analysis on any git repository to build a graph of symbols, dependencies, and execution flows, with optional embeddings for semantic search. - Interactive Web Visualization: Serves the GitNexus production web UI through a zero-dependency Node.js reverse proxy that unifies the UI and API on one port with no CORS issues. - Remote Sharing via Tunnel: Exposes the explorer through a Cloudflare quick tunnel so anyone with the link can browse the graph. - Use Case: A developer onboarding to an unfamiliar repo indexes it, starts the proxy and tunnel, and shares the trycloudflare.com URL with teammates so everyone can visually explore call chains and module clusters. ## Quick Start Index this repository with GitNexus and give me a shareable Cloudflare tunnel URL for the interactive knowledge graph explorer.

Frequently Asked Questions about gitnexus-explorer

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a knowledge graph of my codebase?▼

Run npx gitnexus analyze inside a git repository to build an index in the .gitnexus directory, then start npx gitnexus serve and the proxy script to explore symbols, call chains, and clusters in the web UI.

How to share a local code visualization tool with remote teammates?▼

Start the GitNexus proxy on a local port, then run cloudflared tunnel with --config /dev/null pointing at that port. Cloudflare prints a public trycloudflare.com URL that anyone with the link can open.

What are the size limits for visualizing a codebase in the browser?▼

The web UI loads the entire graph into browser memory, so repos under about 5,000 files work well. Repos with 30k or more nodes will be sluggish or crash the tab, though the CLI and MCP tools work at any scale.

Why does my Cloudflare quick tunnel return 404 errors?▼

An existing named tunnel config at ~/.cloudflared/config.yml has a catch-all ingress rule that intercepts quick tunnel requests. Pass --config /dev/null to cloudflared to bypass the existing config.

Does GitNexus support semantic search over code?▼

Yes, pass --embeddings to npx gitnexus analyze to enable semantic search and natural language queries in the AI chat panel. It takes minutes on large repos instead of seconds, so skip it for quick exploration.
