Simple chatbots answer questions — AI agents take actions. If you need something that can look up data, call APIs, complete multi-step tasks, or make decisions based on context, I build custom AI agents using OpenAI, Claude, or open-source models with tool-calling and memory. I scope the actual capability you need first, since "AI agent" means different things for different use cases, and start with the smallest reliable version before adding complexity. What's included:  • Agent capability scoping  • Tool/function calling setup (APIs, databases, etc.)  • Memory/context handling if needed  • Testing across real scenarios  • Documentation for maintaining or extending the agent
