Huzzah wants your intent in a file, not a chat log. The prototype hasn't got there yet.
Daniel Vaughn's experimental editor treats pseudocode as the durable artifact and generated source as output. The public build sends the whole spec to a model and shows read-only code.

What happened
- Daniel Vaughn has published Huzzah, an experimental AI coding editor built around persistent, developer-written pseudocode, and the project's source code is public on GitHub.
- Huzzah tests whether human-authored intent can remain a durable software artifact instead of disappearing inside coding-agent chats.
- Huzzah's current public prototype is much narrower than its premise: it sends a full pseudocode input to OpenAI and displays read-only generated code, without reconciliation, review states or accept-or-reject controls.
- Vaughn's complaint is that chat records a sequence of requested changes while source code becomes the lasting artifact, so a developer's original intent can end up scattered across discarded sessions, repeated instructions and implementation details authored by a model.
- Huzzah grew from Vaughn's frustration with spending increasing amounts of time describing code changes in longform English, even as coding agents became capable enough to handle much of the implementation.

Why it matters
Daniel Vaughn has published Huzzah, an experimental AI coding editor built around persistent, developer-written pseudocode, with its source public on GitHub [1]. The bet is that human-authored intent can stay a durable software artifact instead of disappearing inside coding-agent chats [2], and the current public prototype is considerably narrower than that bet: it sends a full pseudocode input to OpenAI and displays read-only generated code, with no reconciliation, review states or accept-or-reject controls [3].
The diagnosis is the strongest part. Chat records a sequence of requested changes, while source code becomes the lasting artifact, so the original intent ends up scattered across discarded sessions, repeated instructions and implementation details written by a model [4]. Vaughn says Huzzah grew from frustration at spending increasing time describing changes in longform English even as agents became capable enough to do the implementation [5]. His article contrasts agent prompts, which he calls "longform, imperative, and transient", with a workflow he describes as "pseudocode, declarative, and persistent" [6]. Vaughn positions the tool as an alternative interface to large language models, not a replacement for coding agents [7]. He identifies himself as a design engineer and Head of UX at Dreadnode, an AI security company whose team page lists him as Head of UX/UI, with roughly 12 to 15 years of web experience [8].
The mechanics are deliberately loose. A developer writes a specification in a file ending in .hz, and Vaughn prescribes no grammar: it can be terse, verbose or organised around whatever concepts suit the author [9]. In his demonstration, a six-line fizz buzz spec generates an implementation; changing fizz_buzz() to fizz_buzz(n) and loop 100 to loop n is meant to produce a variable-iteration version [10]. Vaughn's article says Huzzah captures the pseudocode diff, uses it as the model prompt and regenerates the affected source [11]. Shopping-cart and todo-list examples describe data structures and operations such as adding an item, calculating a checkout total and toggling a task's completion state, and Vaughn argues a language-agnostic specification could eventually support several languages or execution environments [12].
That diff step is the load-bearing claim, and it is the one the public build does not demonstrate: full-document submission and read-only output is a different mechanism from diff-guided regeneration of affected source, and without review states there is nothing to reconcile a spec edit against code a model has already changed [13]. The repository describes the project as an experimental interface for editing persistent pseudocode and synchronising it with an AI-generated implementation, running locally on Node.js 22.19 or newer against a model provider supported by the Pi coding-agent framework [14]. Documented providers include Anthropic, OpenAI, Google, Azure OpenAI, Amazon Bedrock, Ollama, LM Studio and vLLM, which is broader plumbing than the demonstration exercises [15]. The reports establish no production deployments, usage metrics or hosted service [16].
Watch for three things: whether pseudocode diffs actually drive regeneration rather than full resubmission, whether accept-or-reject controls arrive so the two artifacts can diverge and be merged, and whether one .hz file ever produces implementations in more than one language [11][3][12]. Vaughn has circled this boundary before with Matry, a design-tooling project described in an earlier profile as an attempt to build a programming language for designers [17].
