What is gsap-animation-suite?

An animation guide for websites and apps built with GSAP, a JavaScript library for creating browser animations. It covers timelines, plugins, SVG effects, and animation settings.

It helps build multi-step animations, coordinate plugins, animate SVG paths and icons, and organise hero-section motion.

It helps prevent choppy motion, layout changes, and competing animations in complex sequences.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00022	$0.00570
Opus 5	$0.00011	$0.00285
Sonnet 5	$0.00004	$0.00114
Haiku 4.5	$0.00002	$0.00057

Security

Grade A, and why

gsap-animation-suite 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 7d 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

CIEL ADAPTATION: GSAP Animation Suite (The Motion Layer)

This skill manages complex animation sequencing and visual polish. it prioritizes performance-safe transforms over layout-heavy properties.

The Motion Mandates

Compositor First: Animate x, y, rotation, and opacity. Prohibit animating width, height, top, or left unless layout reflow is explicitly required.
Timeline Discipline: Prefer gsap.timeline() for multi-step sequences. Use the Position Parameter ("<", "+=0.2") instead of chaining delay.
Plugin Registration: Register every plugin (Flip, Draggable, MorphSVG) ONCE at the application root.

Architecture & Sequencing

Defaults: Set gsap.defaults({ duration: 0.5, ease: "power2.out" }) to ensure consistent "feel."
Nesting: Break complex "Hero" animations into nested timelines for maintainability.
Overwrite: Use overwrite: "auto" to prevent conflicting animations from fighting over the same property.

Visual Integrity (SVG)

DrawSVG: Use for "path writing" effects. requires stroke-width in CSS.
MorphSVG: Use for icon transitions. Convert primitives to paths via MorphSVGPlugin.convertToPath() early.
Origins: Use svgOrigin for rotation around a global SVG point; transformOrigin for local center.

Anti-Patterns

Delay Chaining: Building a sequence by manually calculating delay: 1.5, delay: 2.0 (brittle).
Invisible Tweens: Failing to use autoAlpha: 0 for hidden elements, leaving them clickable.
Jittery CSS: Mixing GSAP transforms with CSS Transitions on the same element.

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.
