SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill eliminates the tedious manual work of scanning entire repositories to understand architecture and cross-file relationships, replacing blind file searches with a structured knowledge graph that AI assistants can query in seconds.

Core Features & Use Cases

  • Knowledge Graph Generation: Automatically extracts entities and relationships from source code, docs, and papers to build a searchable graph.
  • MCP Server Integration: Exposes graph tools via a local MCP server so AI assistants can resolve, explain, and path-find through your codebase.
  • Multi-Repo Support: Index and query across multiple repositories in a workspace for enterprise-scale codebases.
  • Incremental Updates: Watch mode rebuilds the graph as you code, keeping it current without manual intervention.

Quick Start

Use the nexo skill to build a knowledge graph from your project directory and then ask natural language questions about codebase architecture and relationships through your AI assistant.

FAQPage Schema
How do I build a knowledge graph from source code for AI assistant analysis?

To build a knowledge graph from source code, nexo uses tree-sitter parsers for AST extraction to automatically identify code entities and relationships, creating a searchable graph for AI assistants.

Can I analyze cross-file relationships across multiple repositories?

Yes, nexo supports multi-repo analysis, allowing you to index and query cross-file relationships and architecture across multiple repositories within a single workspace.

What is MCP server integration for codebase investigation?

MCP server integration exposes the generated knowledge graph via a local server, enabling AI assistants to resolve, explain, and path-find through your codebase architecture.

Do I need Python 3.10 to extract AST from source code?

Yes, nexo requires Python 3.10 or higher to run the tree-sitter parsers needed for AST extraction and knowledge graph generation.

How do I keep a codebase knowledge graph current without manual rebuilds?

You can keep your codebase knowledge graph current using nexo's incremental updates watch mode, which automatically rebuilds the graph as you modify your code.

What is the best way to understand codebase architecture without scanning files manually?

The best way to understand codebase architecture is transforming repositories into a queryable knowledge graph, replacing blind manual file searches with structured queries an AI assistant can resolve in seconds.
