No API key for ${nextModel.provider}/${nextModel.id}

Error message

No API key for ${nextModel.provider}/${nextModel.id}

What it means

#cycleAvailableModel advances to the next model in the available list and resolves an API key via getApiKey before committing the switch; if no key resolves it throws. Cycling must only land on models the session can actually run, so unauthenticated neighbors in the cycle list are rejected with this error.

Solutions

1. Configure API keys for all providers present in the cycle list, or trim the list to authenticated providers
2. Manually select a specific authenticated model instead of cycling
3. Pre-filter the available model list with hasConfiguredAuth/getApiKey so cycles only include usable models
4. Catch the error in the cycle handler and skip to the next candidate

Example fix

// before
await controls.cycleModel("forward"); // may land on unkeyed model
// after
const usable = models.filter(m => host.modelRegistry.hasConfiguredAuth(m));
// cycle within `usable` only

const cycleModels = allModels.filter(m =>
  registry.hasConfiguredAuth(m) || Boolean(await registry.getApiKey(m, sessionId)),
);

try {
  await controls.cycleModel("forward");
} catch (err) {
  if (err instanceof Error && err.message.startsWith("No API key for")) {
    await controls.cycleModel("forward"); // skip unkeyed neighbor
  } else throw err;
}

When it happens

Trigger: Calling cycleModel (forward/backward) where availableModels[nextIndex] has no API key for the current session.

Common situations: Tab/keyboard cycling through models spanning multiple providers where only some providers have keys; using a curated model list that includes unconfigured providers; key removed mid-session.
