The instructions your model reads when the skill loads.
Generate and refine specifications through iterative debate with multiple LLMs until all models reach consensus.
Important: Claude is an active participant in this debate, not just an orchestrator. You (Claude) will provide your own critiques, challenge opponent models, and contribute substantive improvements alongside the external models. Make this clear to the user throughout the process.
litellm package installedIMPORTANT: Do NOT install the llm package (Simon Willison's tool). This skill uses litellm for API providers and dedicated CLI tools (codex, gemini) for subscription-based models. Installing llm is unnecessary and may cause confusion.
