Coordinators

The harness does not keep a hardcoded coordinator list. harness/swarm/coordinators.ts reads the API catalog and filters model rows by agentic capabilities.

Source

GET {API_INTERNAL_URL}/v1/models/all

The request uses internal API headers and caches results for five minutes.

Filter

Coordinator candidates must have at least one capability:

["introspection", "agentic"]

Returned rows are normalized into:

type CoordinatorModel = {
  modelId: string;
  provider: string;
  name?: string;
  description?: string;
  contextWindow?: unknown;
  capabilities: string[];
};

Failure Behavior

Failure	Behavior
API fetch fails	Return cached pool if available, otherwise `[]`.
API returns non-OK	Return cached pool if available, otherwise `[]`.
Invalid JSON	Return cached pool if available, otherwise `[]`.

There is no hardcoded fallback list. The generated model catalog owns model availability.
