SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? When working with GitNexus, developers need a single reference for its MCP tools, queryable resources, and graph schema before they can run code intelligence queries like impact analysis or execution flow tracing. ## Core Features & Use Cases - Tool Reference: Documents seven MCP tools including query, context, impact, detect_changes, rename, cypher, and list_repos. - Resource Navigation: Lists lightweight gitnexus:// resources for repo context, clusters, processes, and schema discovery. - Graph Schema Reference: Defines node types (File, Function, Class, Method) and edge relations (CALLS, IMPORTS, EXTENDS) with Cypher query examples. - Use Case: Before asking "what breaks if I change this function", read this guide to learn that the impact tool computes blast radius at depths 1-3, then route to the gitnexus-impact-analysis skill. ## Quick Start Ask the assistant to show what GitNexus tools are available and how to query the knowledge graph for your repository.

FAQPage Schema
What GitNexus tools are available for code analysis?▼

GitNexus provides seven MCP tools: query for execution flows, context for symbol views, impact for blast radius, detect_changes for git-diff impact, rename for multi-file renames, cypher for raw graph queries, and list_repos for discovering indexed repositories.

How do I query the GitNexus knowledge graph with Cypher?▼

Read the gitnexus://repo/{name}/schema resource first to learn node types and edge relations, then use the cypher tool. For example, match CodeRelation edges of type CALLS to find all callers of a function.

What should I do before running GitNexus queries?▼

Read the gitnexus://repo/{name}/context resource to get a codebase overview and check index freshness. If the index is stale, run npx gitnexus analyze in the terminal before querying.

Which GitNexus skill should I use for impact analysis?▼

Use gitnexus-impact-analysis for blast radius questions like what breaks if I change X. For architecture questions use gitnexus-exploring, for bug tracing use gitnexus-debugging, and for renames use gitnexus-refactoring.

What node and edge types does the GitNexus graph schema support?▼

Nodes include File, Function, Class, Interface, Method, Community, and Process. Edges are expressed via CodeRelation.type with values CALLS, IMPORTS, EXTENDS, IMPLEMENTS, DEFINES, MEMBER_OF, and STEP_IN_PROCESS.
