Show ponytail measured impact as a scoreboard: less code, less cost, more speed, from the agentic benchmark averages. One-shot display.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Ponytail Gain Display this scoreboard when invoked. One-shot: do NOT change mode, write flag files, or persist anything. The figures are the published agentic benchmark of Ponytail 5: headless Claude Code (Opus 5.5, default effort) on 39 tasks (feature tickets in a real FastAPI + React repo, bug fixes, security and privacy cases, small apps), 5 runs each, against the same agent without the skill. 18 of the tasks have hidden checks for correctness and safety. Each figure is the geometric mean of the per-task medians. They are measured, not computed from the current repo. Source: `benchmarks/results/2026-10-07-agentic.md` and the README. ## Scoreboard Render plain ASCII bars. The bar length shows ponytail as a share of the no-skill baseline; the label carries the exact figure: ``` ponytail gain benchmark · 39 tasks × 5 runs · Opus 5.5 no-skill ████████████████████ 100% Lines of code █████████··········· 47% ▼ 53% Output tokens ███████████········· 55% ▼ 45% Cost ███████████████····· 74% ▼ 26% Time ████████████········ 59% ▼ 41% Hidden checks passed 97% (no-skill 96%) …

How to install
mdr add dietrichgebert/ponytail/ponytail-gain@sha256:40efb084e29bfaaaThe line at the top of this page pins the label git:20261015.84740e3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
