 > **Why doesn't Orchestrator auto-call Council more often?** This is intentional. Council runs multiple models at once, so automatic delegation is kept strict because it is usually the highest-cost path in the system. In practice, Council is meant to be used manually when you want it, for example: <code>@council compare these two architectures</code>.

 > [!NOTE]
 > **Why a separate agent?** If your Orchestrator model is not multimodal, enable Observer to handle images, screenshots, PDFs, and other visual files. Observer is disabled by default and gives the Orchestrator a dedicated multimodal reader without forcing you to change your main reasoning model. Set `disabled_agents: []` and an `observer` model in your configuration.
