Model registry unavailable in current session.

Error message

Model registry unavailable in current session.

What it means

#runAgentCreationArchitect needs the session's model registry to list and refresh available models before spawning the architect sub-session. If this.#modelContext.modelRegistry is unset (e.g. the hub is rendered in a context without model registry wiring), it throws this error instead of proceeding.

Solutions

1. Start a normal interactive session so the model registry is populated before opening the agents hub
2. Ensure the component is constructed with a valid modelContext containing modelRegistry
3. Initialize/await model context setup before triggering agent creation
4. Retry after session initialization completes

Example fix

// before
await hub.runAgentCreationArchitect(desc) // modelContext.modelRegistry === null
// after
if (!hub.modelContext?.modelRegistry) await session.initializeModelContext()
await hub.runAgentCreationArchitect(desc)

if (!session.modelContext?.modelRegistry) {
  await session.initialize(); // or surface a clear setup error
}

function hasModelRegistry(ctx: unknown): ctx is { modelRegistry: NonNullable<typeof ctx extends { modelRegistry: infer R } ? R : never> } {
  return typeof ctx === "object" && ctx !== null && "modelRegistry" in ctx && (ctx as any).modelRegistry != null;
}

try {
  await hub.runAgentCreationArchitect(desc);
} catch (err) {
  if (err instanceof Error && err.message.includes("Model registry unavailable")) {
    // re-open hub after session model context is ready
  } else throw err;
}

When it happens

Trigger: Invoking the agent creation flow while this.#modelContext.modelRegistry is null/undefined — typically when the AgentsHubComponent was constructed without a model context or in a session type that does not supply one.

Common situations: Running the hub before the session fully initializes model context; embedding the component in tests or SDK usage without providing modelContext; session started in an offline/degraded mode where the registry was never attached.
