Introducing Nexa Code — Harness Native AI Assistant

The first AI coding assistant built on the Harness six-tuple H=(E,T,C,S,L,V). Not a framework — a language property. Interactive REPL with autoloop, @tool, with_context, snapshot, reflect, and verify.

From Zero to MVP — Building the First Transpiler

How we built the Nexa transpiler in 6 weeks: Lark parser, Earley algorithm, AST transformer with ambiguity scoring, and a Python code generator that turns .nx files into runnable code.
