 "title": "Verify a bug fix by reading live component state",
 "page_title": "How to verify a bug fix by reading live component state with Medula",
 "summary": "Let an agent read and check a running app's component state after a fix, without editing source files.",
 "who": "A developer or coding agent fixing a production bug in a Vue, React, Svelte, or Solid web app, who needs to confirm the fix at the verification step.",
 "problem": "Checking a bug fix often means clicking through the running app by hand to see what state the components hold, which is slow and easy to miss.",
 "outcome": "The agent reports the current component tree and state of the running page, so the fix can be confirmed against what the app actually holds.",
 "steps": [
  "Install Medula and Vite DevTools with `pnpm add -D medula @vitejs/devtools`.",
  "In vite.config.ts, set `devtools: true` and add `medula()` next to your framework plugin.",
  "Add the MCP server to your agent's configuration with command `npx` and args `devframe connect`.",
  "Start your dev server, open the app in your browser, and complete any DevTools connection code prompt.",
  "Keep the app tab visible while the agent works, then ask it to show the components on the page and their current state."
 ],
 "agent_prompt": "Using the medula MCP tools from the medula repo, connect to the running dev server for <app-port> and list the components on the current page with their state. Expected output: a list of components with their state values. Verify that the values match what the open browser tab shows.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "Changes affect only the running page and do not edit your source files, so any real fix still has to be made in code.",
 "category": "Software and DevOps",
 "tags": [
  "Software and DevOps"
 ],
 "lang": "typescript",
 "requirements": [
  "A web app built with Vue 3, React, Svelte 5, or Solid, run through Vite 8, Nuxt (with Nuxt DevTools 4), or Next.js (App Router)",
  "pnpm and Node.js available to install the package",
  "An MCP-capable coding agent to connect to devframe",
  "A browser tab open to the running app"
