● The Problem

Technical documentation rots. Links break, screenshots show old UIs, API examples use deprecated endpoints, and style guide rules are ignored. Docs drift from reality faster than anyone can manually audit.

● The Solution

A CI tool that lints your documentation. Checks for broken links, validates code examples, compares screenshots against live UI, and enforces style rules (terminology, formatting, voice). Runs on every PR.
