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 installed? RETICLE_INSTALL_SOURCE=npx_skill npx @reticlehq/server@latest init, then the install-and-verify skill.

Electron: two lines, none in your app code

// vite.config.ts — desktop:true also runs the plugin for `vite build`, because a packaged
// renderer is a production build with no dev server
export default defineConfig({
  base: './', // file:// needs relative asset paths
  plugins: [react(), reticle({ desktop: true })],
});
