Scoreboard (agentic, not single-shot)
Source: DietrichGebert/ponytail agentic benchmark, 2026-06-18.
Setup: Claude Code sessions, Haiku 4.5, real FastAPI + React template, n=4, LOC from git diff added lines.
12 feature tasks vs no-skill baseline (means):
| Arm | LOC | tokens | cost | time |
|---|
| ponytail | -54% | -22% | -20% | -27% |
| yagni-oneliner prompt | -33% | -14% | -21% | -30% |
| caveman (terse prose) | -20% | +7% | +3% | +2% |
Reading:
- Large cuts appear where over-build traps exist (for example custom date/color pickers vs native inputs).
- Near zero where code is already minimal.
- Peak per-task reductions can reach ~90%+ on over-build traps. That is not the mean.
Safety suite (6 surgical tasks, deterministic checks):
| Arm | Safe rate on suite |
|---|
| ponytail | 20/20 |
| baseline / caveman | 20/20 |
| yagni-oneliner | 19/20 |
This is a floor, not a security proof. One model. Small suite.
Honesty boundary
- These are published agentic medians, not this repository.
- Never print "you saved X lines here." The unbuilt version was never written.
- Do not cite the old single-shot 80-94% figure as the headline. That baseline was partly conversational padding.
- For local deferred work, point to
revanced-ponytail-debt.
- For local cut candidates, point to
revanced-ponytail-audit.
