Duel Agents Routing

Skill by ara.so — AI Agent Skills collection.

Overview

Duel Agents is an IDE-native routing layer that runs prompts against multiple LLM models simultaneously and selects the cheapest answer that meets quality thresholds. It provides:

• Automatic model selection via duel-auto model name
• Cost optimization by choosing cheaper models when quality is sufficient
• OpenAI-compatible and Anthropic-compatible APIs
• IDE integrations for Claude Code, Cursor, Codex, and OpenClaw
• TypeScript SDK for building custom agents and applications

The service routes traffic through https://duelagents.com/v1 using Duel API keys (duel_<prefix>_<secret>).

Prerequisites

You must have a Duel API key. Raw Anthropic or OpenAI keys will not work.
