1
Define the task
Set boundaries, completion criteria and human checkpoints.
Agent engineering
AI Agent Development
Build tool-using agents with MCP, function calling, retrieval, memory and reliable multi-step execution patterns.
Move from a prompt demo to an observable agent workflow.
Structured learning path
Learn in the order developers build.
Start with the decision, move into implementation and finish with production checks.
2
Connect tools
Use tool calling or MCP with strict schemas and permissions.
3
Add context
Combine retrieval, memory and stable cached instructions.
4
Evaluate runs
Measure completion, corrections, latency and cost per task.

Frequently asked questions
What makes an AI agent different from a chatbot?
An agent can choose and execute tools across multiple steps while tracking state toward a defined outcome.
When should an agent use memory?
Use memory only when information must persist across steps or sessions; keep transient reasoning and durable user facts separate.
