Actually, that approach may work for a demo, but production support needs much more.

When a customer asks to check an order, change a reservation, or request a refund, the system needs to manage 𝙨𝙩𝙖𝙩𝙚, 𝙩𝙤𝙤𝙡𝙨, 𝙥𝙚𝙧𝙢𝙞𝙨𝙨𝙞𝙤𝙣𝙨, 𝙫𝙖𝙡𝙞𝙙𝙖𝙩𝙞𝙤𝙣, 𝙖𝙣𝙙 𝙚𝙭𝙚𝙘𝙪𝙩𝙞𝙤𝙣.

A solid architecture looks like this:

✅ 𝙆𝙚𝙚𝙥 𝙨𝙩𝙖𝙩𝙚 𝙤𝙪𝙩𝙨𝙞𝙙𝙚 𝙩𝙝𝙚 𝙇𝙇𝙈: your application should manage session data, transactions, authentication, and tool results.

✅ 𝙐𝙨𝙚 𝙩𝙝𝙚 𝙇𝙇𝙈 𝙖𝙨 𝙖 𝙧𝙤𝙪𝙩𝙚𝙧: let the model understand intent, choose the right tool, and extract parameters.

For example:

𝚐𝚎𝚝_𝚘𝚛𝚍𝚎𝚛_𝚜𝚝𝚊𝚝𝚞𝚜(𝚘𝚛𝚍𝚎𝚛_𝚒𝚍)
𝚒𝚗𝚒𝚝𝚒𝚊𝚝𝚎_𝚛𝚎𝚏𝚞𝚗𝚍(𝚘𝚛𝚍𝚎𝚛_𝚒𝚍)

The backend should handle the actual database operations and business rules.

✅ 𝙆𝙚𝙚𝙥 𝙚𝙭𝙚𝙘𝙪𝙩𝙞𝙤𝙣 𝙙𝙚𝙩𝙚𝙧𝙢𝙞𝙣𝙞𝙨𝙩𝙞𝙘: tools should return structured results. Your runtime decides what happens next.

If validation fails, permissions are missing, or human intervention is required, your application should handle it with explicit rules.

The key separation is simple:

𝑳𝑳𝑴 → 𝒓𝒆𝒂𝒔𝒐𝒏𝒊𝒏𝒈 & 𝒓𝒐𝒖𝒕𝒊𝒏𝒈
𝑩𝒂𝒄𝒌𝒆𝒏𝒅 → 𝒃𝒖𝒔𝒊𝒏𝒆𝒔𝒔 𝒍𝒐𝒈𝒊𝒄 & 𝒆𝒙𝒆𝒄𝒖𝒕𝒊𝒐𝒏
𝑹𝒖𝒏𝒕𝒊𝒎𝒆 → 𝒔𝒕𝒂𝒕𝒆 & 𝒐𝒓𝒄𝒉𝒆𝒔𝒕𝒓𝒂𝒕𝒊𝒐𝒏

That separation is what makes an AI agent more predictable, auditable, and reliable in production.

An AI support agent isn't just a chatbot with a better prompt; 𝙄𝙩'𝙨 𝙖 𝙨𝙤𝙛𝙩𝙬𝙖𝙧𝙚 𝙨𝙮𝙨𝙩𝙚𝙢 𝙬𝙞𝙩𝙝 𝙖𝙣 𝙇𝙇𝙈 𝙞𝙣𝙨𝙞𝙙𝙚 𝙞𝙩.
