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