Context.md — The Repository Context Layer

A proposed standard for AI project context: one markdown file, versioned with the code, that agents consult before planning and update after executing — under human review. Git stores what changed; Repository Context stores what the project knows. Ships with a minimal spec, an example, and a short whitepaper.

Why I Built Discovery Quest

A father of three on turning screen time into a curiosity engine: a voice-first learning world guided by Luna the owl, with an AI-native open-core engine where courses are data an AI can draft and a validator can prove.
