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.

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 | $0.00024 | $0.00869 |
| Opus 5 | $0.00012 | $0.00434 |
| Sonnet 5 | $0.00005 | $0.00174 |
| Haiku 4.5 | $0.00002 | $0.00087 |
Grade A, and why
mobile-touch 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.

Mobile Touch Animation
Apply Disney's 12 animation principles to mobile gestures, haptics, and native app motion.
Quick Reference
| Principle | Mobile Implementation |
|---|---|
| Squash & Stretch | Rubber-banding, bounce on scroll limits |
| Anticipation | Peek before reveal, long-press preview |
| Staging | Sheet presentations, focus states |
| Straight Ahead / Pose to Pose | Gesture-driven vs preset transitions |
| Follow Through / Overlapping | Momentum scrolling, trailing elements |
| Slow In / Slow Out | iOS spring animations, Material easing |
| Arc | Swipe-to-dismiss curves, card throws |
| Secondary Action | Haptic pulse with visual feedback |
| Timing | Touch response <100ms, transitions 250-350ms |
| Exaggeration | Bounce amplitude, haptic intensity |
| Solid Drawing | Respect safe areas, consistent anchors |
| Appeal | 60fps minimum, gesture continuity |
Principle Applications
Squash & Stretch: Implement rubber-band effect at scroll boundaries. Pull-to-refresh should stretch content naturally. Buttons compress on touch.
Anticipation: Long-press shows preview before full action. Drag threshold provides visual hint before item lifts. Swipe shows edge of destination content.
Staging: Use sheet presentations to maintain context. Dim and scale background during modal focus. Hero transitions connect views meaningfully.
Straight Ahead vs Pose to Pose: Gesture-following animations (drag, pinch) are straight ahead—driven by touch input. System transitions (push, present) are pose to pose—predefined keyframes.
Follow Through & Overlapping: Content continues moving after finger lifts (momentum). Navigation bar elements animate slightly after main content. Lists items settle with stagger.
Slow In / Slow Out: iOS uses spring physics—configure mass, stiffness, damping. Android Material uses standard easing: FastOutSlowIn. Never use linear for user-initiated motion.
Arc: Thrown cards follow parabolic arcs. Swipe-to-dismiss curves based on velocity vector. FAB expand/collapse follows natural arc path.
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.

mobile-touch is a skill published in the GitHub repository dylantarre/animation-principles (80 stars, last pushed 8mo ago), licensed MIT. It adds 24 tokens to every session and 869 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 2026-08-30.
