Author shares real-world results for Ponytail 5 (benchmarked on 5,700+ Claude Code sessions, 39 tasks): 53% less code, 41% faster completion, 26% cheaper, 45% fewer tokens — while 98% of risky logic still ships with a test (vs 68% without).
The philosophy isn't reckless deletion: before writing, it asks whether the code needs to exist, whether it's already available, whether the browser/language natively covers it, and whether it can be one clear line.
