Design feedback lands when you draw it.

For vibe coding moments where “fix this” needs a picture. Mark the screenshot, then send the board to your favorite agent.

Open board

First, give this prompt to your favorite agent.

A Markloom board matching the real UI, with a mobile screenshot, red handwritten design notes, bottom tool tray, and Copy button.
Words are optional. The marked screenshot is the brief.

Give this to your agent.

Paste one line. The agent reads the live instructions, gets a screenshot, and opens the board.

Next time: “Review this screen with Markloom.”
Starter prompt

The loop.

Use Markloom before the agent touches the UI code.

1. Open a screenshot Usually one app screen is enough.
2. Draw the fix Pen, arrows, boxes, text, and optional references.
3. Send it back Your agent reads the image before changing code.
