lost-rob0t Ponytail Gain
External import of Ponytail by Dietrich Gebert and contributors, adapted from upstream v4.9.0 under MIT.
Goal
Show Ponytail's published benchmark impact without pretending it measures the current repository.
Output
Render this compact scoreboard:
ponytail gain upstream benchmark median · 5 tasks · 3 models
Lines of code no-skill 100%
ponytail 6–20% down 80–94%
Cost no-skill 100%
ponytail 23–53% down 47–77%
Speed ponytail 3–6x faster
Then point repository-specific follow-up to ponytail-debt for counted deferrals and ponytail-audit for currently cuttable complexity.
Rules
- These are upstream benchmark medians, not measurements of the current repository.
- Never invent a per-repo savings number: the unbuilt baseline does not exist.
- One-shot display only; do not change Ponytail mode or repository state.
