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 | $0.02485 |
| Opus 5 | $0.00011 | $0.01242 |
| Sonnet 5 | $0.00004 | $0.00497 |
| Haiku 4.5 | $0.00002 | $0.00248 |
Grade A, and why
motion-principles 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.
This is a copy
98% identical to motion-principles — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Motion Principles
The foundation. Loaded by every creative skill invocation. Concise rules here. Deep-dive in
references/.
Timing Rules
| Context | Duration | Why |
|---|---|---|
| Micro-interaction (toggle, hover, focus) | 100-150ms | Instant feedback, no perceived delay |
| UI transition (modal, drawer, tab switch) | 200-300ms | Smooth but never sluggish |
| Page/route transition | 300-500ms | Establishes spatial narrative |
| Scroll-driven / 3D | Free (progress-based) | Tied to user input, no fixed duration |
Frequency rule: The more often an animation plays, the shorter and subtler it must be. A button hover (1000x/day) = 100ms opacity. An onboarding reveal (1x ever) = 600ms+ full choreography.
Easing Cheat Sheet
| Action | Easing | Why |
|---|---|---|
| Element enters | ease-out / spring |
Decelerates into resting position (natural arrival) |
| Element exits | ease-in |
Accelerates away (gets out of the way) |
| Element moves between states | ease-in-out |
Smooth start and stop |
| Scroll-synced | linear / none |
Matches 1:1 with input, no lag perception |
| Bouncy/playful | spring (underdamped) | Overshoot creates life |
| Snappy UI | cubic-bezier(0.2, 0, 0, 1) |
Fast start, smooth land |
Exit is always more subtle than enter. Enter: 300ms ease-out, full choreography. Exit: 200ms ease-in, opacity only.
Native easing equivalents (cross-platform)
| Web (CSS / JS) | SwiftUI | Compose |
|---|---|---|
cubic-bezier(0.2, 0, 0, 1) |
.spring(response: 0.4, dampingFraction: 0.85) or .snappy |
spring(stiffness = Spring.StiffnessMedium, dampingRatio = 0.85f) |
ease-out |
.easeOut(duration: 0.3) |
tween(durationMillis = 300, easing = LinearOutSlowInEasing) |
ease-in |
.easeIn(duration: 0.2) |
tween(durationMillis = 200, easing = FastOutLinearInEasing) |
| spring (bouncy) | .bouncy (iOS 17+) |
spring(stiffness = Spring.StiffnessLow, dampingRatio = Spring.DampingRatioMediumBouncy) |
| spring (smooth) | .smooth (iOS 17+) |
spring(stiffness = Spring.StiffnessMedium, dampingRatio = Spring.DampingRatioNoBouncy) |
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

motion-principles is a skill published in the GitHub repository Kenyi001/oraculo-radiohead (0 stars, last pushed 12d ago), licensed MIT. It adds 22 tokens to every session and 2,485 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 98% identical to motion-principles, differing in 2 lines, and is treated as a copy.
