What it does

Ponytail Gain is an agent skill from usenotra/notra. Show ponytail's measured impact as a compact scoreboard: less code, less cost, more speed, from the benchmark medians.

Example prompts

What it can do on your machine

Read from SKILL.md and the folder at commit dceb2a7. 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 457 tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 147 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~79
When it runs · the whole SKILL.md, loaded when a task matches: ~457

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 benchmark medians. 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 benchmark medians (5 everyday tasks: email validator, debounce, CSV sum, countdown timer, rate limiter; three models: Haiku, Sonnet, Opus). They are measured, not computed from the current repo. Source: benchmarks/ and the README.

Scoreboard

Render plain ASCII bars. The bar length shows the measured range; the label carries the exact figure:

  ponytail gain                     benchmark median · 5 tasks · 3 models

  Lines of code   no-skill  ████████████████████  100%
                  ponytail  ██▌·················    6–20%   ▼ 80–94%
  Cost            no-skill  ████████████████████  100%
                  ponytail  █████▌··············   23–53%  ▼ 47–77%
  Speed           ponytail  ▸ 3–6× faster

  This repo:  /ponytail-debt  (shortcuts you deferred)
              /ponytail-audit (what's still cuttable)

Honesty boundary

These are benchmark medians, 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.
