Error message

model provider not configured

What it means

errModelProviderNotConfigured is a sentinel error returned by coordinator.run (line 261), Summarize (line 1240), and runSubAgent (line 1425) when the provider named by the active model's ModelCfg.Provider is not found in the resolved Providers config. The provider config is required to build API credentials/options (mergeCallOptions, token refresh), so the run is aborted.

Solutions

1. Add the missing provider block to your crushrc so it matches the model's provider id.
2. Update the model selection (large/small model settings) to a model whose provider is configured.
3. Check config load logs for provider merge/load failures and fix the source config.

Example fix

// before
provider "openai" { ... }
model "anthropic/claude-sonnet-4" // provider missing
// after
provider "anthropic" {
  api_key env.ANTHROPIC_API_KEY
}
model "anthropic/claude-sonnet-4"

model := coord.CurrentModel()
if _, ok := cfg.Providers.Get(model.ModelCfg.Provider); !ok {
    return fmt.Errorf("provider %q for selected model %q is not configured", model.ModelCfg.Provider, model.ID)
}

result, err := coord.Run(ctx, sessionID, prompt)
if errors.Is(err, errModelProviderNotConfigured) {
    // add the provider block or switch models, then retry the run
}

When it happens

Trigger: Run/Summarize/runSubAgent invoked after UpdateModels resolved a model whose Provider string has no matching entry in cfg.Config().Providers — e.g. the model came from a different config layer, the provider block was removed, or the provider id is misspelled.

Common situations: Deleting or renaming a provider block while models still reference it; env-specific config overlays dropping a provider; OAuth providers whose config failed to load; switching models to one whose provider was never set up.
