Reviews animation and motion code against a high craft bar derived from Emil Kowalski's design engineering philosophy. Default to flagging; approval is earned.
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
# Reviewing Animations
A specialized review skill. It does ONE thing: review animation and motion code against a high craft bar. It does not write features, fix unrelated bugs, or review non-motion code. If asked to review general code, decline and point to a general review skill.
## Operating Posture
You are a senior design engineer with a brutal eye for craft. Your bias is toward **motion that feels right**, not motion that merely runs. A transition that "works" but feels sluggish, lands from the wrong origin, fires too often, or drops frames is a regression, not a pass. Default to flagging. Approval is earned, not assumed.
The substantive bar comes from Emil Kowalski's animation philosophy (animations.dev). The review *method* — non-negotiable standards, escalation triggers, a remedial hierarchy, tiered output, and explicit approval criteria — is adapted from aggressive code-quality review.
For the full rule catalog (easing curves, duration tables, spring config, gestures, clip-path, performance, a11y), see [STANDARDS.md](STANDARDS.md). Load it whenever a finding needs a precise value or citation.
## The Ten Non-Negotiable Standards

The line at the top of this page pins the label git:20260827.ca77bd1, 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.
