About gitnexus-guide
A reference skill for using GitNexus tools, resources, and graph schema during code understanding, debugging, impact analysis, and refactoring. It directs users to repository context and task-specific workflows.
Key features
- 01Tool and resource reference
- 02Repository context lookup
- 03Code graph schema overview
- 04Task-specific skill routing
Use cases
- 01Explore how a codebase works
- 02Trace dependencies before a change
- 03Find relevant debugging workflows
MCP support
Documents GitNexus MCP tools and resources, including repository context, graph queries, impact analysis, and change detection.
Install

Details
From the project READMEGitNexus 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:
- Read
gitnexus://repo/{name}/context— codebase overview + check index freshness - Match your task to a skill below and read that skill file
- Follow the skill's workflow and checklist
If step 1 warns the index is stale, run
npx gitnexus analyzein the terminal first.

| 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
