What it does

Ponytail Gain is an agent skill from hashgraph-online/awesome-codex-plugins. 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".

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.

Example prompts

“ponytail gain”

What it can do on your machine

Read from SKILL.md and the folder at commit 3e1456a. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ponytail Gain loads about 501 tokens when it runs. Until then it costs about 81 tokens; SKILL.md has 170 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~81
When it runs · the whole SKILL.md, loaded when a task matches: ~501

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: ponytail-gain
description: 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%
  Lines of code   █████████···········   46%   ▼ 54%
  Tokens          ████████████████····   78%   ▼ 22%
  Cost            ████████████████····   80%   ▼ 20%
  Time            ███████████████·····   73%   ▼ 27%
  Safety kept     100%  (validation, error handling, security)

  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.
