Agent runtime and orchestration
An agent is a definition — a prompt, a model, and the tools it is allowed to touch. The orchestrator runs it as a loop, and can delegate to other agents as though they were tools.
A hard-coded chain answers one shape of question; anything else means another chain. Making the agent a record rather than a code path is what turns one workflow into a platform, and delegation is what lets a long job be composed out of short ones.
Agents are authored at organisation or personal scope against a tool registry with graded privileges. A run can be triggered from chat, from the API, or on a schedule described in plain language and confirmed before it is set.
