Usage
Loaded automatically when its description matches the active task. The body below provides the working context.
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:
- 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 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
