GroundRules: Skill for Claude Code

.agents/skills/awwwards-animations/SKILL.md

awwwards-animations is a skill for Claude Code, Codex from chama-x/GroundRules. It costs 27 tokens per session (351 once invoked), scanned A, original, MIT.

A set of rules for making website motion and animations feel polished, covering timing, easing, scrolling effects, and interactive responses.

In plain words
What is it for?
Use it when building premium-style website animations, such as page transitions, parallax scrolling, hover feedback, or buttons that respond to the pointer.
Why use it?
It gives an agent concrete standards to follow when ordinary animation defaults are not good enough, while helping avoid distracting or uncomfortable motion.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is chama-x/GroundRules's own configuration. It tells Claude Code and Codex how to work on GroundRules itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything GroundRules configures →

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

awwwards-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 8d 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.

What it actually says

Premium Motion Configuration

This is a configuration profile, not a textbook. You already know how to write animations. When the user requests Awwwards-level quality, enforce these specific constraints:

Easing & Timing

  1. Never use defaults: linear, ease-in, ease-out are forbidden.
  2. Custom curves: Default to power3.out, power4.out, or custom cubic-bezier curves (0.76, 0, 0.24, 1) for premium tension.
  3. Duration: Entrances should be snappier (0.6s - 1.2s). Exits should be faster (0.3s - 0.5s).

Scroll & Parallax

  1. Smooth Scroll: If full-page scroll effects are requested, mandate a virtual scroll hijacking library like Lenis. Native scroll is not sufficient for premium parallax.
  2. Parallax depth: Use subtle transform-y offsets (e.g., -10% to 10%). Avoid extreme parallax that induces motion sickness.

Interactions

  1. Latency: Micro-interactions (hover, click) must trigger visual feedback within 100ms.
  2. Magnetic effects: If implementing magnetic buttons, calculate distance from center using getBoundingClientRect() and apply spring physics, not linear lerping.

Transitions

  1. Overlap: Page transitions must overlap. The outgoing page should start animating out before the incoming page finishes animating in.

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.

awwwards-animations is a skill published in the GitHub repository chama-x/GroundRules (5 stars, last pushed 24d ago), licensed MIT. It adds 27 tokens to every session and 351 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
