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.

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 | $0.00045 | $0.00732 |
| Opus 5 | $0.00023 | $0.00366 |
| Sonnet 5 | $0.00009 | $0.00146 |
| Haiku 4.5 | $0.00005 | $0.00073 |
Grade A, and why
motion-choreography-patterns 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 yesterday.
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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Motion Choreography Patterns
How multiple moving parts coordinate in time and space to communicate
interaction intent. Mechanism selection and tokens live in motion-systems;
this skill owns sequencing.
Choreography Model
Treat each sequence as three actor layers:
- Primary actor - the element representing the state change
- Supporting actors - nearby elements that reinforce context
- Environment actors - backdrop, scrim, container, page-level continuity
Animate primary first, then supporting, then environment unless the interaction model requires the reverse.
Timing Architecture
Use predictable beat structure:
- Lead beat (
0-80ms) - immediate acknowledgment - Primary beat (
120-240ms) - main state change - Follow beat (
20-60msoffset) - supporting context update - Settle beat (
80-180ms) - final stabilization
Favor asymmetry: exits slightly faster than enters.
Core Choreography Principles
- One dominant axis per beat (avoid conflicting direction signals)
- Keep simultaneous high-amplitude motions limited
- Use stagger only when it improves scan order and hierarchy
- Keep rhythm consistent across similar components
- Preserve spatial anchors during reflow/reorder transitions
Pattern Library

For reusable stagger utilities, see:
Input-to-Motion Mapping
- Tap/click: immediate visual response in under
80ms - Press/hold: include press state before commitment transition
- Drag: motion follows pointer directly; settle animation occurs only on drop/commit
- Keyboard navigation: preserve focus continuity and avoid disorienting travel
Reduced Motion Choreography
When reduced motion is requested:
- Remove spatial travel when possible
- Keep sequencing logic with opacity/state changes
- Preserve hierarchy with contrast, layering, and timing rather than movement distance
- Ensure state change remains obvious and immediate
What ships with it
4 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-choreography-patterns is a skill published in the GitHub repository scott-fryxell/brayness (120 stars, last pushed 2d ago), licensed MIT. It adds 45 tokens to every session and 732 once invoked, about $0.0002 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.
