How to Edit Prompts Smartly in Media Agents

Editor’s Media Agents combine image generation and text generation to create visual drafts such as Instagram Stories, social posts, thumbnails, and more.
While you can modify prompts inside the Agent Editor, the fastest and most powerful way to refine your agent output is by using Edit Prompt inside any draft.

This guide walks you through adjusting both the image prompt and the text prompt to get exactly the visuals and copy you want.

1. Understanding Your Media Agent

In the example from the video, the Instagram Story Media Agent contains:

• A logo at the top

• The copy (text) at the bottom

• A generated image

• A mask layer behind the image for stylistic effect

We start by applying this Media Agent to an article about the U.S. government shutdown and generating a draft.

2. Accessing the Edit Prompt Feature

Once the draft is created:

1. Open the Draft

2. Click Edit Prompt

3. You will see:

   • Left side: Your editable prompt

   • Right side: A real-time preview of the image + text output

This allows you to iterate instantly and see the changes without modifying your main agent yet.

3. Fixing Incorrect or Irrelevant Image Outputs

Sometimes your previous prompt instructions may accidentally influence a new request.
In the example, the generated image incorrectly showed:

• An airport

• Random flights

• Irrelevant context

This happened because the agent still contained leftover instructions from a previous draft.

To fix this:

1. Remove the irrelevant lines inside the image prompt ("airport", "flights", etc.)

2. Add new logic, for example:

If the article speaks about political issues, show an image of the president of the country.
Also include a very famous monument of that country so the reader understands which country the article is about.

3. Click Rerun

The new output is immediately better—Trump signing documents, relevant to the political story.

4. Improving the Image Even Further

If you want a better alternative, simply:

• Press Rerun Image again

• Generate unlimited variations until the style fits your needs

In the video, one of the reruns produced an image with the White House behind Trump—perfect for posting.

5. Editing the Copy (Text Prompt)

The copy may sometimes be too long or too dense for social media formats.

In the tutorial:

• The text was set to 200 characters

• The creator wanted something shorter

To adjust:

1. Edit the instruction:

   Limit the output to 100 characters.
   

2. Press Rerun

3. The copy regenerates instantly with the new limit.

This is useful for:

• Instagram Stories

• Reels

• TikTok overlays

• Twitter/X headlines

• Carousel slides

6. Applying the Agent to a New Article

After refining the prompts, the creator applies the Media Agent to a new article about:

Dallas Mavericks firing GM Nico Harrison

The generated image contains unwanted text and numbers.

7. Using Edit Prompt to Refine the Image Rules

To fix this:

1. Open Edit Prompt

2. Add a new instruction:

   Never showcase dimensions, numbers, characters, or letters inside the generated image.
   

3. Press Rerun

The new image is clean, aesthetic, and social-media ready.

Final Tips

• The Edit Prompt feature is the fastest way to iterate both visuals and copy.

• Use real-time reruns to get the best image without editing the global agent until you are ready.

• When your prompt is perfected, copy your improved instructions back into the Media Agent for consistent future results.

• Use clear, simple, direct instructions for maximum control over AI-generated visuals.
