How to Build an AI Agent
A practical architecture for building an AI agent with a model, tools, memory, permissions, and observability.
- STEP 01
Define the job
Start with the smallest useful implementation. Define inputs, outputs, dependencies, failure modes, and the boundary between automated actions and human decisions. Test one measurable outcome before expanding the system.
- STEP 02
Choose the model
Start with the smallest useful implementation. Define inputs, outputs, dependencies, failure modes, and the boundary between automated actions and human decisions. Test one measurable outcome before expanding the system.
- STEP 03
Add tools
Start with the smallest useful implementation. Define inputs, outputs, dependencies, failure modes, and the boundary between automated actions and human decisions. Test one measurable outcome before expanding the system.
- STEP 04
Add state
Start with the smallest useful implementation. Define inputs, outputs, dependencies, failure modes, and the boundary between automated actions and human decisions. Test one measurable outcome before expanding the system.
- STEP 05
Secure it
Start with the smallest useful implementation. Define inputs, outputs, dependencies, failure modes, and the boundary between automated actions and human decisions. Test one measurable outcome before expanding the system.
- STEP 06
Test and observe
Start with the smallest useful implementation. Define inputs, outputs, dependencies, failure modes, and the boundary between automated actions and human decisions. Test one measurable outcome before expanding the system.
