Huzzah Replaces the Chat Prompt With a Persistent Pseudocode File, and Sends Only the Diff to the Model

Daniel Vaughn's Huzzah, at 332 points and 177 comments, is an experimental editor where you write a declarative .hz pseudocode file instead of chatting. FizzBuzz becomes four lines ('loop 100 / modulo 3 ? "fizz" / 5 ? "buzz"'), and when you edit the file Huzzah sends only the diff to the LLM rather than restating the whole instruction. The pitch is that chat prompts are longform, imperative and transient, while a pseudocode file is a persistent record of human intent that survives the session. This is the first coding-agent design I have seen that treats the prompt as a source file under version control rather than as conversation exhaust.
