What it does

Gitnexus Guide is an agent skill from aws-samples/sample-kolya-br-proxy, published by the product's own GitHub organization. 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?"

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Knowledge Management, covering Knowledge graphs. It works with Model Context Protocol. The licence is MIT-0.

When your agent uses it

  • The user asks about GitNexus itself — available tools
  • How to query the knowledge graph
  • Workflow reference

Example prompts

  • “What GitNexus tools are available?”
  • “How do I use GitNexus?”
  • “/gitnexus-guide”

Requirements

  • Node.js

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  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

What it can do on your machine

Read from SKILL.md and the folder at commit 9c3dcee. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Gitnexus Guide loads about 867 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 241 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~867

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
