Fusion-Fable: a panel of AI models that double-check each other

A Claude Code skill that asks several frontier models the same question, lets them work independently, then has Opus 4.8 weigh their answers and fuse the best into one. Built for moments when a confident-but-wrong reply would actually cost you.

Fusion-Fable is a Claude Code skill that turns a single question into a small panel of AI models. It sends the same prompt to several frontier models — configurations include two Opus 4.8 runs, Opus paired with GPT-5.5, or a three-way mix that adds Gemini 3.1 Pro — and each one works independently with web search and shell access. Opus 4.8 then acts as a judge, mapping out where they agree, where they contradict, and what unique points each surfaced, before writing one synthesized answer.

Why a vibe-coder should care

If you've ever shipped something based on an AI answer that sounded sure and turned out wrong, this is the cure: a second and third opinion baked into one command, plus an audit trail showing how the verdict was reached. It costs more tokens and time, so it's meant for the hard, high-stakes questions rather than everyday chatter.
