Stop regenerating.
Start converging.

RHA Wrapper compiles a prompt into a frozen test contract before any implementation exists, builds each feature against it, and repairs failures inside bounded node boundaries. Iterate while progress is being made; escalate — never regenerate — when it stalls. Works with Claude, or the model already loaded in your LM Studio / Ollama.

Launch App Get the Provider Vault extension

The doctrine — three levels

Setup — the extension comes first, keys stay on your machine

1. Download the Provider Vault extension and extract it somewhere permanent.
2. Open chrome://extensions ⧉ (click to copy, paste into Chrome's address bar — Chrome blocks direct links to its own pages).
3. Enable Developer mode (top-right switch at chrome://extensions ⧉), click Load unpacked, pick the extracted folder.
4. Create your vault (AES-256-GCM, PBKDF2 — the key never leaves the extension's memory).
5. Add a provider. RHA Wrapper works with ChatGPT, Claude, and Gemini, local LMs (LM Studio / Ollama), and any other provider that complies with the OpenAI-compatible schema. Paste an API key (or a local server URL, e.g. http://localhost:1234/v1) and the model name — local servers auto-detect. Set Active — the server hot-reloads, no restart.
6. Launch the app and paste an already-defined feature spec — author the features with your LLM of choice (ChatGPT, Claude, …): one feature per line, observable behavior + edge cases. You don't describe an idea here; you paste a spec. Compile.

Run it locally — no jargon

Everything runs on your own computer. Nothing is uploaded, nothing phones home, and the files stay on your drive for as long as you want them. Here is the whole thing, step by step.

1. Unzip it. You get a folder. Put it wherever you like — Desktop is fine. It just sits there; that folder is the app.
2. Install Node.js once, from nodejs.org (free, official — click the big green button, run it, click Next). It's the engine that runs the app.
   what is Node.js?

   The standard, open-source runtime for JavaScript apps — the same thing that runs a huge share of the web. Installing it does not change your system; it just lets your computer run programs like this one.
3. Open the app — double-click the one file named for your system:
   • Mac: double-click run.command
   • Windows: double-click run.bat
   • Linux: run ./run.sh
   You do not hunt for a .js file — it's the one named run. The first launch spends a minute getting the pieces it needs; after that it's instant.
   “getting the pieces it needs” — what pieces? (nothing scary)

   A handful of well-known open-source building blocks, downloaded once into the folder:

   • Express — the tiny local web server that serves the app to your browser.
   • React — the interface you click around in.
   • Vite — builds that interface.
   • TypeScript / tsx — runs the code.
   • Vitest — runs the frozen tests that verify generated code (the whole point of RHA).
   • Anthropic SDK — only used if you pick Claude as your model.

   That's the entire list. None of it talks to us; all of it lives in your folder.
4. Your browser opens to the app at http://localhost:4100. Bookmark that page — it's your permanent door in. Any time you want RHA later, double-click the same run file again and your bookmark loads it.
5. Rather not double-click anything? Open your computer's Terminal (Mac/Linux) or Command Prompt (Windows), drag the unzipped folder onto the window and press Enter, type npm run dev and press Enter — then open http://localhost:4100 in any browser yourself. Exact same result, fully by hand.

What did it just do? The launcher started RHA as a small web server on your machine and pointed your browser at it — that's all. No account, no upload, no background installer. Close the window to stop it; double-click run to start it again. The folder can live on your hard drive forever.

It self-updates — even as a downloaded clone

A copy on your disk is not a dead snapshot. From the owner admin panel you can Check for updates against the origin (rha.software), see the version and hash, and click once to apply a verified patch. Updates are never silent: HTTPS only, sha256-matched, and only after an explicit click. You can also revert to any of the last 5 patches. A reverted install shows as RHAWrapper Legacy (yellow/orange) until you update forward again.
