When you're working in Claude and want a second opinion on your code or approach, this lets you query GPT, Gemini, Grok, or any of the 400+ models available through OpenRouter without leaving your environment. It's straightforward: you're deep in a Claude Code session, hit a design decision or tricky implementation, and want to see how another model would handle it. Instead of copying context to another chat interface, you invoke the deliberation server and get alternative perspectives inline. Useful when you want to validate an approach, compare reasoning styles, or just sanity check something against a different model's strengths before committing.
