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

Error message

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

What it means

ModelControls.setModel refuses to switch the session's model when the model registry has no configured authentication for the target model (hasConfiguredAuth(model) is false). This guards the persistent model switch so a turn never starts against a provider the user cannot authenticate to. The message names the provider/model that lacks a key.

Solutions

1. Configure auth for the target provider (set its API key env var or add credentials via `omp` auth/config) before switching
2. Pick a different model on a provider that already has configured auth
3. Check hasConfiguredAuth(model) on the registry before calling setModel
4. If auth should exist, verify the correct provider profile/config file is loaded and the key is present in the environment

Example fix

// before
await controls.setModel({ model: anthropicModel }); // throws if no key
// after
if (host.modelRegistry.hasConfiguredAuth(anthropicModel)) {
  await controls.setModel({ model: anthropicModel });
} else {
  await controls.setModel({ model: fallbackModel });
}

if (!session.modelRegistry.hasConfiguredAuth(model)) {
  console.warn(`Skipping ${model.provider}/${model.id}: no API key configured`);
  return;
}
await controls.setModel({ model });

try {
  await controls.setModel({ model });
} catch (err) {
  if (err instanceof Error && err.message.startsWith("No API key for")) {
    // prompt user to configure provider auth or pick another model
  } else throw err;
}

When it happens

Trigger: Calling setModel({ model, ... }) (directly or via applyRoleModel) with a Model whose provider has no API key / auth configured in the registry.

Common situations: Selecting a model from a provider that was never configured (no env var like ANTHROPIC_API_KEY, no models.json auth entry, no logged-in provider); switching roles to a model on an unconfigured provider; key was removed or expired from config before the switch.
