When an AI agent gives an unexpected or incorrect reply in the Agent Inbox, the fastest way to understand what went wrong is to reproduce the exact conversation in the Playground and inspect the sources used. This guide shows you how to safely reproduce a conversation, identify which instructions or sources influenced the answer, and fix the underlying issue.

​
Why reproducing conversations matters

When a reply feels incorrect, incomplete, or off-brand, the fastest way to understand why is to reproduce the exact user message in the Playground. This allows you to see exactly what the agent used to generate its answer — including:
  • Instructions
  • Connected websites
  • XML feeds
  • Uploaded files
  • Other knowledge sources
Instead of guessing, you can debug agent behavior with full transparency.

​
When should you use this?

Use this method when:
  • An answer is factually incorrect
  • The tone does not match your personality settings
  • The response is incomplete
  • The agent ignores specific product or company information
  • The agent says it doesn’t know something that should be in its sources
If you notice recurring mistakes, always reproduce the original message first before adjusting settings or retraining.
For the smoothest workflow, open Watermelon in:Two browser tabs side by side• One tab → to view the conversation in the Agent Inbox
• One tab → to reproduce the message in the PlaygroundThis allows you to compare both views in real time and quickly test adjustments.If you ever experience session or caching issues, you can optionally use an incognito window for one of the tabs to simulate a fresh session.
1

Open the conversation in the Inbox

Guides Handle Spammers
  • Navigate to the conversation where the agent’s response did not meet expectations.
  • Identify the user message that triggered the response.
  • Copy the message exactly as sent.
2

Reproduce the message in the Playground

Guides Finding Root Of Issue 1
  • Open the Playground for the same agent used in the conversation.
  • Make sure the agent configuration matches the one that was active when the conversation happened.
  • Paste the copied user message into the input field and send it.
If instructions, sources, or model settings were changed after the conversation happened, the reproduced answer may not match the original reply.
3

Inspect the sources used by the agent

  • Under the agent’s response, locate the Source: label.
  • Click one of the source chips/buttons (for example: Instructions, Website, XML feed).
Expand the dropdown to see which information was used to generate the answer.

Next Steps: Fix and Confirm

Once you’ve identified the cause:
  • Unclear instructions → Edit the agent instructions and make them more specific
  • Broken or outdated URLs → Update or remove them, then re-sync if applicable
  • Incorrect XML feed data → Validate the feed and refresh the connection
  • Unexpected sources → Remove the source or tighten instructions to restrict usage
After making changes, reproduce the same message again in the Playground to confirm the fix before monitoring future Inbox conversations.
