Worldcup

A general best-of-N selection engine wearing a World Cup-style tournament. Any time a task is "mass-produce many candidates and keep the single best" (or the user hands over a field of them), stage 32 teams (8 groups of 4) or 48 teams (12 groups, 2026 format) through a head-to-head round-robin group stage into a single-elimination knockout, judged by taste-calibrated LLM panels, and emit a World Cup-flavored HTML report of the final bracket graph. The "teams" can be anything comparable: essay or copy variants, taglines, names, API or UI designs, prompts, configs, plans, generated code solutions. Essays/prose are one supported profile, not the required shape. This skill should be used when the user wants to bracket a field and crown a winner with real rigor, or whenever a task reduces to "make N variants and pick the best." Triggers: "/worldcup", "run a worldcup", "tournament these", "bracket these 32", "best of N", "mass-produce and pick the best", "stage 48 variants and crown a winner", "group stage then knockout". Requires the ultracode Workflow tool. The judge is the point: domain profiles plug in a fatal-flaw/fabrication gate, a fact-ledger truth anchor (the original competes as one of the N when you want it judged), calibrated pairwise seeding, diverse-lens panels, Elo rating confirmation, and optional cross-model (agentify) jurors for the finals.
