What is json-schemas?

This repository is a collection of structured templates, called JSON schemas, that Microsoft uses to make sure configuration files are formatted correctly. Think of a schema as a blueprint or set of rules that defines what a file should look like, what fields are required, what's optional, and what types of information are valid. When a developer tool checks a file against one of these schemas, it can catch typos or missing pieces before they cause problems. The schemas are hosted on Microsoft's website and organized in this repository by folder. However, you wouldn't normally visit that URL directly in your browser to read them. Instead, various Microsoft tools and services automatically point to the exact schema file they need behind the scenes, using the structure here as the source of truth. The people who would interact with this repository directly are Microsoft employees maintaining or updating these schemas across different product teams. For everyone else, developers using Microsoft tools, the benefit is indirect but practical: their editor or tooling can auto-complete fields, validate inputs, and flag errors based on the rules defined here. For example, if you're configuring a Microsoft service and forget a required setting, the tool can warn you immediately because it checked the file against the relevant schema. The README doesn't go into detail about which specific products or schemas are included, or how the publishing pipeline works. What's clear is that this is an internal-facing publishing mechanism, Microsoft teams contribute schemas here, and the files are served at a predictable URL so that tools can reference them reliably. It's essentially the behind-the-scenes plumbing that makes "smart" configuration validation possible across Microsoft's ecosystem.
