Agents are designed to do almost any kind of work, from answering support tickets to writing code. No matter how complex the workload, how long it runs, or how many turns it takes to complete, every agent needs three core capabilities to operate:

Agents need to connect to models and route between them

Agents need to run workflows across many steps

Agents need to connect to the systems that make them useful and the platforms people use to interact with them

Implementing these capabilities to build a complete agent forces developers to choose between vendor lock-in with a single provider API, stitching together solutions, or building abstractions themselves.

The Agent Stack gives you all the building blocks you need to create and ship production-grade agents.
