Arbitrage

Arbitrage is a Claude Code skill that optimizes AI token usage by routing expensive frontier-model tokens only to judgment tasks (planning, architecture, review) while dispatching all code-writing to the cheaper Codex agent running in the background. It includes a visual validation loop for frontend work and an escape hatch that falls back to the premium model after two failed Codex attempts. Think of it as cost-aware orchestration for agentic coding workflows.

Ponytail

A skill system for AI coding agents that enforces minimal, necessary code. Before writing anything the agent walks a decision ladder (does it need to exist, is it already in the codebase, can stdlib handle it) and only writes new code as a last resort. Reports roughly 54% fewer lines, 20% lower cost, and 27% faster runs versus baseline.
