What does this agent skill do?

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%

  Hidden checks passed   97%  (no-skill 96%)
  Tests where the logic needs one   98%  (no-skill 68%)

  This repo:  /ponytail-debt  (shortcuts you deferred)
              /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.

How can the creator link this skill?

Add the canonical catalog link to the repository README so users can inspect current installs and available audits. The publishing guide covers the complete discovery path.
