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 with one mobile screenshot, red handwritten design notes, a text tool, and a 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.
