SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Developers using GitNexus need a single reference for its MCP tools, resources, and graph schema before they can query a codebase's knowledge graph effectively. This Skill provides that quick reference and routes each task type to the correct workflow. ## Core Features & Use Cases - Tools Reference: Documents the seven GitNexus MCP tools including query, context, impact, detect_changes, rename, cypher, and list_repos. - Resources Reference: Lists lightweight gitnexus:// resources for repo context, clusters, processes, and schema navigation. - Graph Schema: Defines node types (File, Function, Class, Method) and edge relations (CALLS, IMPORTS, EXTENDS) with example Cypher queries. - Use Case: When asked "What breaks if I change this function?", the Skill directs you to read the repo context resource, then follow the impact-analysis workflow using the impact tool. ## Quick Start Ask the assistant which GitNexus tools are available and how to query the knowledge graph for your indexed repository.

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

GitNexus provides seven MCP tools: query for process-grouped code intelligence, context for 360-degree symbol views, impact for blast radius analysis, 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 understand node and edge types, then use the cypher tool. For example, match CodeRelation edges of type CALLS to find all callers of a specific function.

What should I do before running GitNexus impact analysis?▼

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

Which GitNexus skill handles debugging and refactoring tasks?▼

Use gitnexus-debugging to trace bugs and understand why code fails, and gitnexus-refactoring for rename, extract, split, and other restructuring tasks. Architecture questions map to gitnexus-exploring and blast radius questions to gitnexus-impact-analysis.

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.
