Gitnexus Guide

This is your reference card for the GitNexus MCP server itself. It maps six task types (exploring architecture, impact analysis, debugging, refactoring, CLI ops, and general reference) to their corresponding skill files, then provides a quick lookup table for all seven tools (query, context, impact, detect_changes, rename, cypher, list_repos) and the MCP resources you can read. The graph schema section shows you the node types and relationship edges if you need to write raw Cypher queries. Think of it as the index page: when you're using GitNexus and forget which tool does what or which skill file to consult for a refactoring job, you come here. It won't teach you workflows, but it will point you to the right skill that will.

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:

Bind the repository once — use a confirmed registry name/path or configured default; call list_repos if unknown. Read hot-tool staleness; use gitnexus://repo/{name}/context when an overview is needed.
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 node .gitnexus/run.cjs analyze in the terminal first. On query / context / impact / cypher, read staleness.status and staleness.branch/lastCommit before using the answer. Re-analyze only for behind or diverged.
