Compare agents on one task

In this example, four agents on four of your accounts get the same task at once, and you read their answers side by side.

Project
launch-site
Agents
Four on your accounts, with any coding agent or API key
Prompt
Find why checkout.spec.ts fails on Safari

You open Compare agents

In the project, + Agent has Compare agents…, in your browser and in the Mac app.

  • You write the prompt once.
  • Every account that can start an agent in the project is on the list, from any provider, coding CLI or API key.
  • You tick two or more. In your browser, you also choose the model for an API key.

Each account gets the same prompt

Miko starts a new agent in the project on each account you ticked and gives it the exact same prompt.

  • Each agent has its own card, which says when the prompt is delivered.
  • The card shows the agent's latest output as it works.
  • The agents work in the same project, so they share its files.

Ran npx playwright test checkout.spec.ts
2 failed in WebKit: the card form times out.
Cause: the card iframe posts its ready message after the 5 s wait.
Fix: wait for the frame's ready event instead (+6 −2).

Open agent
Explored tests/checkout.spec.ts, src/checkout/CardForm.tsx
Cause: CardForm mounts the iframe only after the fonts load, and WebKit fires that late.
Fix: mount the iframe at once and show a skeleton (+11 −4).

Read tests/checkout.spec.ts
Cause: Safari blocks the third-party cookie the card frame sets, so the form never loads.
Fix: serve the frame from our own domain in tests (+8 −1).

You pick the answer you want

You read each agent's answer and ask the one you agree with to make its fix.

  • In your browser, Open agent takes you to that agent. On the Mac, each card has the agent's conversation.
  • Nothing picks a winner. You compare the answers yourself.
  • Each one is an ordinary agent in the project, which you can keep working with.

What you end up with

  • Four answers to the same prompt
  • Each agent on its own account
  • One card per agent, side by side
  • The fix you pick, made by the agent that found it

Good to know

  • Works with Claude Code, Codex, Cursor and every other coding agent, plus any API key.
  • Each agent runs on your own account or API key, which it uses as it always does. Miko doesn't sell AI usage.
  • In your browser, one comparison takes up to eight accounts.
  • On the Mac, you check the message and the accounts once more before it goes out.
