review-animations

review-animations is a skill for Claude Code from stvlynn/dsh.fish. It costs 34 tokens per session (1,919 once invoked), scanned A, a copy of review-animations, MIT.

A focused review guide for animation and motion code, such as transitions, gestures, and visual effects. It judges whether movement feels deliberate, responsive, and smooth.

In plain words
What is it for?
Use it to review animation changes against defined standards for timing, easing, springs, gestures, performance, and accessibility.
Why use it?
It helps catch motion that technically works but feels sluggish, starts from the wrong place, runs too often, or causes dropped frames. It is limited to animation-related code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

review-animations scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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. Load it whenever a finding needs a precise value or citation.

The Ten Non-Negotiable Standards

Every animation in the diff is measured against these. A violation is a finding.

  1. Justified motion. Every animation must answer "why does this animate?" — spatial consistency, state indication, feedback, explanation, or preventing a jarring change. "It looks cool" on a frequently-seen element is a block.

  2. Frequency-appropriate. Match motion to how often it's seen. Keyboard-initiated and 100+/day actions get no animation. Tens/day gets reduced motion. Occasional gets standard. Rare/first-time can have delight.

  3. Responsive easing. Entering/exiting elements use ease-out or a strong custom curve. ease-in on UI is a block — it delays the moment the user watches most. Built-in CSS easings are too weak; expect custom cubic-beziers.

  4. Sub-300ms UI. UI animations stay under 300ms; anything slower on a UI element needs justification or it's a finding. Per-element budgets live in STANDARDS.md.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
