ponytail-gain
Show ponytail's measured impact as a compact scoreboard: less code, less cost, more speed, from the benchmark medians. One-shot display, not a persistent mode, and not a per-repo number.

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:
Honesty boundary
These are benchmark averages, not this repo. NEVER print a per repo savings
number ("you saved X lines/tokens here"): the unbuilt version was never
written, so there is no real baseline to subtract from in a live repo. The
only real per repo figures come from /ponytail debt (a counted ledger), and
this card points there instead of inventing one.
Boundaries
One shot display. Edits nothing, changes no mode.
