Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 143 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00079 | $0.01591 |
| Opus 5.5 | $0.00032 | $0.00636 |
| Sonnet 5.5 | $0.00016 | $0.00318 |
| Haiku 4.5 | $0.00008 | $0.00159 |
Grade A, and why
gsap-tackl 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 16d 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 — 161 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GSAP (Tackl)
System overview
app/(site)/Providers.tsx
└── AnimationPlugins # registers ScrollTrigger + useGSAP globally
└── Contexts
└── PerformanceProvider # isReducedMotion, devicePixelRatio

Animation is client-side only. Never run Lenis/GSAP in Server Components.
Stack
gsap+@gsap/react(useGSAP)ScrollTrigger— registered insrc/components/AnimationPlugins/index.tsx- Project hook:
useAnimationinsrc/utils/useAnimation.ts(wrapsuseGSAP+gsap.matchMedia)
Do not re-register plugins in every file. AnimationPlugins is imported once in app/(site)/Providers.tsx.
When to use what
| Need | Tool |
|---|---|
| Smooth scroll | Lenis via SmoothScroll — already mounted, do not duplicate |
| Scroll-linked reveal/scrub | GSAP ScrollTrigger via useAnimation |
| Responsive breakpoints | useAnimation matchMedia (isDesktop, isMobile, isTablet) |
| Simple mount tween (no breakpoints) | useGSAP |
| Route transitions | React <ViewTransition> via @parts/PageTransition + transitionTypes on next/link |
| Reduced motion fallback | PerformanceContext.isReducedMotion |
Rules
- GSAP code belongs in client components (
'use client'). - Prefer
useAnimationfor responsive / scroll work; pass{ scope: ref }when using selectors. - Prefer refs over class selectors when possible.
- Always scope cleanup —
useGSAP/useAnimationhandle this viagsap.context(). - Interaction-driven animations (click, delayed) are not context-safe — manage and revert manually.
- Respect
PerformanceContext— skip or simplify whenisReducedMotionis true. - Animate
transformandopacityfirst; avoid layout properties.

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.

gsap-tackl is a skill published in the GitHub repository 12-Studio/Tackl (10 stars, last pushed 15d ago), licensed MIT. It adds 79 tokens to every session and 1,591 once invoked, about $0.0003 per session on Opus 5.5. 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.
