Memory Agent demo logs are verbose and misleading #473
Description
When running the Mem0 Memory Agent example from the corresponding sample code, the logging output is confusing and misleading.
For most queries, including the accompanying demo, the example prints the following very large and visually dominant message:
╭──────────────────────────────────────── No Matches ────────────────────────────────────────╮
│ No memories found matching the query. │
╰────────────────────────────────────────────────────────────────────────────────────────────╯
Immediately after that, a valid response or result is still produced, but it is far less visible. This gives the false impression that the agent failed, even though it actually succeeded.
Additionally, the demo repeatedly logs messages such as Error processing memory action....... From a user perspective, these look like hard errors, even though the agent continues functioning correctly.
Together, these logs make the example noisy, misleading, and harder to understand for new users. The example is presented as a reference implementation, so this behavior sets incorrect expectations about failure and success paths.
The expected behavior would be quieter defaults, clearer separation between real errors and expected empty-memory states, and logs that emphasize the actual agent output rather than internal bookkeeping.
Full logs from a clean demo run are attached below.

Thank you for sharing your travel plans with me. I've stored the information about your trip to Japan in February 2026 using business class.
It seems I don't have any previous information about your travel preferences or past trips to Japan. However, I'd be happy to help you plan this exciting journey. Here are some initial thoughts and questions to get us started:
1. Duration: How long are you planning to stay in Japan?
2. Specific cities: Are there particular cities or regions in Japan you'd like to visit?
3. Interests: Are you interested in any specific activities, such as visiting historical sites, experiencing modern Japanese culture, or enjoying nature?
4. Accommodation preferences: Do you have any preferences for accommodation, such as luxury hotels or traditional ryokans?
5. Airline: Do you have a preferred airline for your business class travel?
Regarding your business class travel:
- February is still winter in Japan, so business class will provide extra comfort for the long flight.
- Many airlines offer excellent business class services to Japan, including JAL, ANA, and international carriers like United, Delta, or Emirates, depending on your departure location.
- Business class will typically include priority check-in, lounge access, lie-flat seats, and enhanced dining options.
Is there any specific aspect of your trip to Japan that you'd like to focus on first? I'm here to help you plan and make the most of your journey!
> What do you know about me?
To provide you with the most accurate and up-to-date information about what I know about you, let me retrieve all the stored memories I have. I'll use the mem0_memory tool to list all the information associated with your user ID.

Based on the results I've received, it appears that I have very limited information about you at the moment. The only piece of information I have stored is what you just told me in our previous interaction. Here's what I know:
1. You are planning a trip to Japan in February 2026.
2. You intend to travel in business class for this trip.
Apart from this recent travel plan, I don't have any other stored information about you, such as your name, age, occupation, preferences, or past interactions.
This limited information suggests that we haven't had many conversations before, or if we have, the information wasn't permanently stored in my memory system.
Is there anything else you'd like to share about yourself that might be helpful for future interactions? I'm here to assist you and can store any relevant information you're comfortable sharing, which could help me provide more personalized assistance in the future. Remember, you're in control of what information you want to share.
> list my preferences
Certainly! I'll use the mem0_memory tool to retrieve and list all the preferences we have stored for you. Let me do that now.

I apologize, but it appears that I don't have any specific preferences stored for you in my memory system. The search for preferences, likes, dislikes, and favorites didn't return any results.
The only information I have about you is what we discussed in our previous interaction:
1. You are planning a trip to Japan in February 2026.
2. You prefer to travel in business class for this trip.
These could be considered preferences, but they're quite specific to your upcoming travel plans rather than general preferences.
If you'd like, we can start building a list of your preferences now. This could include things like:
1. Travel preferences (e.g., preferred airlines, accommodation types, travel styles)
2. Food preferences
3. Hobbies and interests
4. Preferred communication style
5. Work or study preferences
6. Entertainment preferences (music, movies, books, etc.)
Would you like to share any preferences in these or other categories? Once you share them, I can store this information to provide more personalized assistance in the future. Remember, you're in control of what information you want to share, and you can always update or remove this information later.
