gitnexus-guide	Use when the user asks about GitNexus itself — available tools, how to query the knowledge graph, MCP resources, graph schema, or workflow reference. Examples: "What GitNexus tools are available?", "How do I use GitNexus?"

GitNexus Guide

Quick reference for all GitNexus MCP tools, resources, and the knowledge graph schema.

Always Start Here

For any task involving code understanding, debugging, impact analysis, or refactoring:

1. Read gitnexus://repo/{name}/context — codebase overview + check index freshness
2. Match your task to a skill below and read that skill file
3. Follow the skill's workflow and checklist

If step 1 warns the index is stale, run npx gitnexus analyze in the terminal first.

Skills

Task	Skill to read
Understand architecture / "How does X work?"	gitnexus-exploring
Blast radius / "What breaks if I change X?"	gitnexus-impact-analysis
Trace bugs / "Why is X failing?"	gitnexus-debugging
Rename / extract / split / refactor	gitnexus-refactoring
Tools, resources, schema reference	gitnexus-guide (this file)
Index, status, clean, wiki CLI commands	gitnexus-cli

Tools Reference

Tool	What it gives you
query	Process-grouped code intelligence — execution flows related to a concept
context	360-degree symbol view — categorized refs, processes it participates in
impact	Symbol blast radius — what breaks at depth 1/2/3 with confidence
detect_changes	Git-diff impact — what do your current changes affect
rename	Multi-file coordinated rename with confidence-tagged edits
cypher	Raw graph queries (read gitnexus://repo/{name}/schema first)
list_repos	Discover indexed repos

Resources Reference

Lightweight reads (~100-500 tokens) for navigation:

Resource	Content
gitnexus://repo/{name}/context	Stats, staleness check
gitnexus://repo/{name}/clusters	All functional areas with cohesion scores
gitnexus://repo/{name}/cluster/{clusterName}	Area members
gitnexus://repo/{name}/processes	All execution flows
gitnexus://repo/{name}/process/{processName}	Step-by-step trace
gitnexus://repo/{name}/schema	Graph schema for Cypher

Graph Schema

Nodes: File, Function, Class, Interface, Method, Community, Process Edges (via CodeRelation.type): CALLS, IMPORTS, EXTENDS, IMPLEMENTS, DEFINES, MEMBER_OF, STEP_IN_PROCESS

MATCH (caller)-[:CodeRelation {type: 'CALLS'}]->(f:Function {name: "myFunc"})
RETURN caller.name, caller.filePath
