gitnexus-guide

A guide to GitNexus, a code knowledge graph that maps relationships in a repository. It documents the available tools, data resources, graph structure, and workflows.

In plain words
What is it for?
Use it as the starting reference for GitNexus queries and for selecting workflows that explore architecture, trace bugs, assess change impact, or plan refactors.
Why use it?
It helps choose the right GitNexus workflow for understanding code, debugging, impact analysis, or refactoring.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gitnexus-guide scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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 node .gitnexus/run.cjs 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 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 (paginated — limit/offset)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
