# Agent Arena ## Overview Agent Arena is a reusable protocol skill for AI coding agents and LLM agent harnesses. Use it when one agent is likely to be overconfident, trapped in a single framing, or missing evidence. The core idea: **independent heterogeneous agents first, debate later, evidence before consensus, dissent preserved.** Agent Arena is designed for Claude Code, OpenAI Codex, Hermes Agent, OpenClaw, OpenCode, Copilot CLI, and other autonomous coding agents or agentic workflows that support custom skills, custom instructions, or tool-driven delegation. **Capability boundary:** this skill is not an executable orchestrator. It does not install, authenticate, or automatically call external agents. Cross-agent execution requires a host agent or human operator with the relevant CLI/tool access, credentials, permissions, and network availability. ## When to Use Use this skill when the task involves: - Multi-agent debate or panel review - Codex vs Claude Code comparison - Architecture decisions or implementation plan reviews - Complex bug root-cause analysis - PR/code review with high consequence - Research synthesis that needs source checking - LLM-as-a-judge, agent judge, agent game theory, or debate workflows - Red teaming a design, prompt, implementation, benchmark, or experiment plan - Avoiding single-model-family blind spots Do **not** use full Agent Arena for: - Simple factual lookups - Translation, formatting, or summarization - One obvious local tool cal...
