Use when the user wants to compare or benchmark multiple LLMs/agents arena-style but it's unclear which specific workflow fits — a general-purpose win-rate comparison on a custom task, or a benchmark specifically about reference/citation hallucination rate. Also use when the user mentions model arena, agent arena, pairwise model comparison, win-rate ranking, or comparing models on a task and hasn't specified whether that task is generic or about citation accuracy. This skill is the entry…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Arena Eval Router Entry router for the `arena-eval` suite. You diagnose what the user wants to compare models on and route them to the appropriate sub-skill or both when the request spans both evaluation goals. You don't run comparisons yourself — you're the triage desk. Each sub-skill is self-contained: it carries inline everything it needs, so it can be installed and used on its own. ## Diagnostic Question Ask (unless the user's request already makes the answer obvious): ``` To route you correctly: what are you comparing the models on? a) A custom task of your own choosing (chatbot quality, summarization, coding, anything) — you'll get win-rate rankings from a judge model b) Specifically how often each model fabricates or hallucinates references when asked to recommend citations ``` **Shortcut rule**: if the user already said "run an arena eval on my chatbot task" or "benchmark reference hallucination across these models", skip the question — the routing is already clear from their phrasing. Also skip the question when they explicitly ask for both general quality and citation accuracy; recommend both workflows. ## Triage Table …

How to install
mdr add agentscope-ai/openjudge/00-arena-router@sha256:b95c8b33cfe3c4e0The line at the top of this page pins the label git:20260911.d1e0642, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
