Once a team has run a few workflows, a pattern shows up: the same handful of agent roles keep reappearing. A planner that decomposes goals the way you like. A reviewer with your quality bar baked into its prompt. Copying those definitions between workflows means every tweak has to be made in a dozen places — and inevitably they drift apart.
Roles as first-class, reusable objects#
The Agent Hub makes an agent role something you define once and reuse everywhere. A hub agent carries its role, system prompt, default model, and tool permissions. Drop it into a workflow and it behaves exactly as defined; update it in the hub and every workflow that uses it picks up the change.
We ship a library of prebuilt roles to start from — planners, researchers, writers, reviewers, classifiers — and you can save your own tuned versions alongside them.
Composition without copy-paste#
This is the difference between a prompt you paste around and a component you import. Workflows become assemblies of well-understood parts, and the work of improving an agent compounds across every place it runs instead of being stranded in one. When a reviewer misbehaves, there's a single definition to inspect and fix — not six near-identical copies that have quietly diverged.
