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?"
Quick reference for all GitNexus MCP tools, resources, and the knowledge graph schema.
For any task involving code understanding, debugging, impact analysis, or refactoring:
gitnexus://repo/{name}/context — codebase overview + check index freshnessIf 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 |
| 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 |
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 |
