Bring-Your-Own-Agent

Definition

Harmony supports both pre-built opinionated agents AND custom / external agents created by customers or partners. External agents can read from and contribute to the shared brain-layer — enabling marketplace-style distribution and reducing the need to build every agent type in-house.
