AgentDeclaration

Type, in @jr2/orchestrator/src/agent.ts. The signature of an export, or a type that it names, names this type. The Authoring surface page lists each export. This type is not an export of @jr2/orchestrator, so a workflow module does not import it by name.

type AgentDeclaration = Omit<AgentDefinition, "model"> & {
  model: string | typeof open;
};

What agent() takes: an AgentDefinition, except that model can also be open.

Fields: each field of AgentDefinition, except model, and these:

• model: string | typeof open

  The model, as <provider>/<modelId>: for example anthropic/claude-haiku-5-5. Required: there is no default model. The provider must be one that jr2.config.ts can reach.

  Or open, in a Machine that you publish as a package. Then the Instance that registers the Machine binds the model with customize(). One Turn may set another model in the invoke's input.
