Agent-as-a-Router Coding Skill

Skill by ara.so — AI Agent Skills collection.

ACRouter is an agentic model routing system that intelligently selects backend models for coding tasks, balancing performance and cost. It uses verifier feedback and escalation strategies to route problems through a hierarchy of models (cheap → strong), stopping when a solution passes verification. This skill covers installation, reproduction of benchmark results, runtime integration, and custom inference patterns.

What ACRouter Does

• Agentic Routing: Routes coding tasks to different models (cheap-first, escalate on failure)
• CodeRouterBench: Public benchmark with ID (in-distribution) and OOD176 (out-of-distribution) tasks
• Verifier-Driven: Uses test execution or static analysis to validate solutions before escalating
• Cost-Performance Tradeoff: Optimizes for high performance per dollar spent
• Runtime Integration: Ships with plugins for Claude Code Router, cc-switch, and generic OpenRouter-compatible APIs
