What it does
00 Arena Router is an agent skill from agentscope-ai/OpenJudge. 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 router for the arena-eval…
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Research & Science, covering Citation management. The repository describes itself as: OpenJudge: A Unified Framework for Holistic Evaluation and Quality Rewards. The licence is Apache-2.0.
When your agent uses it
- The user wants to compare
- A benchmark specifically about reference/citation hallucination rate
- The user mentions model arena
- Pairwise model comparison

What it can do on your machine
Read from SKILL.md and the folder at commit d1e0642. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
00 Arena Router loads about 1k tokens when it runs. Until then it costs about 164 tokens; SKILL.md has 380 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- 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 router for the arena-eval suite: it asks one diagnostic question when needed, then recommends the workflow or workflows needed to cover the request.
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 citationsShortcut 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
| User says / has | Use workflow | What it does |
|---|---|---|
| "Compare/benchmark/rank these models on [any custom task]" | 01-auto-arena | Generates queries from a task description, collects responses, auto-generates rubrics, runs pairwise judge comparisons, produces win-rate rankings |
| "Which model hallucinates citations least?" / "benchmark reference recommendation accuracy" | 02-ref-hallucination-arena | Runs reference-recommendation queries per model, verifies every returned citation against CrossRef/PubMed/arXiv/DBLP, ranks by verified accuracy |
| "Compare general helpfulness AND citation accuracy" | 01-auto-arena, then 02-ref-hallucination-arena | Runs separate evaluations for judge preference and verified citation accuracy, preserving both goals |
| "I want to review one paper's existing bibliography, not compare models" | — | Not this suite — see the academic-eval suite's 01-paper-review / 02-bib-verify instead |

Key distinction
Both workflows produce model rankings from head-to-head-style evaluation, but differ in what "correct" means:
01-auto-arena: correctness is judge opinion — an LLM judge scores pairwise which response is better for an arbitrary task. Works for any task, needs no ground truth.02-ref-hallucination-arena: correctness is externally verifiable — every cited reference is checked against real bibliographic databases (CrossRef/PubMed/arXiv/DBLP), so the ranking reflects factual accuracy, not judge preference. Narrower scope (citation recommendation only) but higher ground-truth confidence.
If the user cares only about citation accuracy, prefer
02-ref-hallucination-arena over 01-auto-arena even if they phrase it as
"which model is better."
Output
Recommended workflow: `[skill-name]`
Why: [one sentence tying the user's request to the triage table row]Recommend one workflow when it covers the request. If the user asks for both
general quality and citation accuracy, recommend 01-auto-arena followed by
02-ref-hallucination-arena as separate runs (or follow the user's requested
order). Explain that the two runs measure different things and report their
results separately; neither ranking substitutes for the other.
