Ponytail: dev-built tool cuts AI agent code by 80-94%, making it 3-6x faster and 47-77% cheaper
anthara_ai · x · 2026-11-09
Frustrated by agents writing 500 lines for a 5-line problem, a developer built Ponytail — named after that veteran engineer who silently replaces your fifty lines with one. The tool makes agents look for a reason NOT to write code first. Benchmarked across Haiku, Sonnet, and Opus (median of 10 runs): 80-94% less code, 47-77% cheaper, 3-6x faster. MIT licensed, works with 10 agents, 1.3k stars.
"The best code is the code you never wrote."
