Drive a desktop app and prove what happened

A desktop app reaches its backend over IPC, not HTTP. Patching fetch/XHR cannot see that, so a browser-shaped tool is blind to every backend call the app makes: the network log reads empty, an action has no in-flight request to settle on, and asserting on the network is vacuously true. That is a false green by construction.

Reticle observes the renderer and the IPC boundary, so a desktop verdict means what a web one does. Not set up? Follow the reticle skill: it installs Reticle, asks the user before init changes the app's files, and proves one flow.

Electron: two lines, none in your app code

// vite.config.ts — desktop:true lets connect() start in a packaged renderer (NODE_ENV=production).
// A default (production-mode) `vite build` ships no Reticle code; to drive a packaged
// renderer with no dev server, build it with `vite build --mode development`
export default defineConfig({
  base: './', // file:// needs relative asset paths
  plugins: [react(), reticle({ desktop: true })],
});
