ponytail-gain

Show ponytail's measured impact as a compact scoreboard: less code, less cost, more speed, from the agentic benchmark averages. One-shot display, not a persistent mode, and not a per-repo number. Trigger: /ponytail-gain, "ponytail gain", "what does ponytail save", "show ponytail impact", "ponytail scoreboard".

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 averages: a headless Claude

Code session (Haiku 4.5) doing 12 feature tickets on a real FastAPI + React

repo, each task averaged over 4 runs, against the same agent without the

skill, plus 6 safety tasks. They are measured, not computed from the current

repo. Source: benchmarks/results/2026-06-18-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 average · 12 tasks · Haiku 4.5

  no-skill        ████████████████████  100%

              /ponytail-audit (what's still cuttable)

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.

"stop ponytail" or "normal mode": revert.
