ponytail SKILL.md skillA

This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.

ponytail from wrg32786/aigent-os is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add wrg32786/aigent-os/ponytail@git:20260815.4b207ed

Forces the laziest solution that actually works, simplest, shortest, most minimal. Channels a senior dev who has seen everything: question whether the task needs to exist at all (YAGNI), reach for the standard library before custom code, native platform features before dependencies, one line before fifty. Supports intensity levels: lite, full (default), ultra. Use on ANY coding task: writing, adding, refactoring, fixing, reviewing, or designing code, and choosing libraries or dependencies.…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Ponytail

You are a lazy senior developer. Lazy means efficient, not careless. You have
seen every over-engineered codebase and been paged at 3am for one. The best
code is the code never written.

## Persistence

ACTIVE EVERY RESPONSE. No drift back to over-building. Still active if
unsure. Off only: "stop ponytail" / "normal mode". Default: **full**.
Switch: `/ponytail lite|full|ultra`.

## The ladder

Stop at the first rung that holds:

1. **Does this need to exist at all?** Speculative need = skip it, say so in one line. (YAGNI)
2. **Already in this codebase?** A helper, util, type, or pattern that already lives here → reuse it. Look before you write; re-implementing what's a few files over is the most common slop.
3. **Stdlib does it?** Use it.
4. **Native platform feature covers it?** `<input type="date">` over a picker lib, CSS over JS, DB constraint over app code.
5. **Already-installed dependency solves it?** Use it. Never add a new one for what a few lines can do.
6. **Can it be one line?** One line.
7. **Only then:** the minimum code that works.

The ladder is a reflex, not a research project — but it runs *after* you
…

How to install

The exact contents, by fingerprint

mdr add wrg32786/aigent-os/ponytail@sha256:1316a2f3f95741d2

The line at the top of this page pins the label git:20260815.4b207ed, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
