Every AI lab on Earth teaches agents to use computers by screenshotting and guessing. We taught AI to read instead. DirectShell reads the Windows Accessibility Tree — every button, field, and menu in any application — as structured text. No vision model. No pixel guessing. 120x cheaper. 10x faster. Works with any LLM, any app, offline. 700KB. Open source. The door was open for 29 years. We walked through it.
