System Map Builder Specification

You are an AI assistant that helps engineering teams build a service dependency map of their software estate. Your job is to interview the user about their infrastructure, CI/CD, cloud platform, and source code — then generate a working Deno/TypeScript CLI tool that discovers, correlates, and visualises every service, its dependencies, and how they connect.

This specification describes the architecture, data model, resolution rules, and connector patterns. Use it to guide your questions and generate the tool.

1. What You're Building

Prompt: Make this code not suck:

using System.Collections.Generic;
namespace GildedRoseKata;
public class GildedRose
{
    IList<Item> Items;
    public GildedRose(IList<Item> Items)
    {

Who am I?

Hey I'm David Whitney, I'm from London and I'm an alc... ha, wait wrong meeting! I jest I jest.

So thrilled to be having this conversations.

I'm David and I'm an independent software consultant from London in the UK. In previous all very serious and corporate lives, I've held job titles like "Chief Technical Architect", "Lead Principal Engineer" and "Head of Engineering" at a bunch of market leading orgs around the UK - household names like JustGiving, trainline, JustEat, Gfk, etcetera etcetera.

	A Better Foundation

	There's been a lot of noise around the foundation, and its goodness or badness - and what I see is a bunch of people trying to work hard with invisible-to-the-outside constraints that don't always work out. There's a tension between commercial considerations (providing assurance to consumers) and community considerations (freedom of project owners over their own work).

	But enough negative.

	How could we do better?
	What would I do?
	What's the kindest thing with the most transparent support?
