Метрики эффективности принципов Ponytail

★ 7.5 · vibe-coding

ponytail-gain is a Claude Code skill that renders a one-shot ASCII scoreboard showing the measured impact of ponytail principles, based on published benchmark medians. The figures come from real tests across 5 everyday tasks — email validator, debounce, CSV sum, countdown timer, and rate limiter — run on three models: Haiku, Sonnet, and Opus. The scoreboard covers three metrics: lines of code (down 80–94%), token cost (down 47–77%), and execution speed (3–6× faster). The skill is strictly read-only: it edits nothing and persists no state; for per-repo analysis it points to /ponytail-debt and /ponytail-audit instead of inventing numbers. It's useful for developers evaluating the concrete value of a minimalist coding approach before adopting it.
