From Prompt Soup to Tools: Designing Agents That Act
Published Sep 21, 2025 • by XAIAGENT Team
Most agents fail not because the models are weak, but because we ask them to do too much with too little structure. In this post, we explore how to wire your agent with **function calling**, **SQL memory**, and **confidence bands** so it behaves like an operator, not a parrot.
Why Actions > Words
When an AI agent is integrated with tools (databases, calendars, APIs), it can solve real tasks. Otherwise, it risks producing text that sounds good but does nothing. Here’s how we solved this in SalesRadarAI.
Key Takeaways
- Always give your agent a "don’t guess" option.
- Use lightweight SQL memory to prevent context rot.
- Evaluate on success metrics (appointments booked, leads found) not just BLEU scores.
