Run the pragmatic-skeptic 'ponytail' reviewer over the current diff to surface over-engineering — code, abstractions, dependencies, files, or process steps the problem does not need. Read-only and advisory; never trims safety, security, accessibility, data-loss handling, or their tests. Use before pushing a PR, when a change feels heavier than the task warranted, or when boilerplate/a new dependency crept in. Triggers: 'ponytail review', 'is this over-engineered', 'what can I delete here'…

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 Review Skill

## What This Skill Does

Spawns the [`ponytail-reviewer`](../../agents/ponytail-reviewer.md) agent
against the current change set and returns its 6-section critique. The
reviewer is the "lazy senior dev" — it looks for the simplest thing that
could work and names what is surplus, without ever touching safety,
security, accessibility, data-loss handling, the tests that guard them,
or the release/ADR process.

It is the active companion to the passive
[`good-boy-scout`](../../rules/good-boy-scout.md) rule, and the
deliberate opposite of [`devils-advocate`](../../agents/devils-advocate.md):
devils-advocate asks "should this be built?"; ponytail asks "is this
bigger than it needs to be?"

**This skill is advisory. It proposes reductions; it never applies them.**
The human or parent agent decides what to act on.

## When to Use This Skill

- Before pushing a PR, as a bloat check.
- When a change feels heavier than the task warranted.
- When boilerplate, a new abstraction, or a new dependency crept in.
- When reviewing whether a *process* change is ceremony or signal.

Do **not** use it as a gate that blocks merges, and do **not** let it

How to install

The exact contents, by fingerprint
mdr add wildcard/caro/ponytail-review@sha256:2013c893948d4a91

The line at the top of this page pins the label v1.0.0, 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.
