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 | $0.00075 | $0.02413 |
| Opus 5.5 | $0.00030 | $0.00965 |
| Sonnet 5.5 | $0.00015 | $0.00483 |
| Haiku 4.5 | $0.00007 | $0.00241 |
Grade A, and why
canon-motion 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 2mo 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 — 216 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CANON · Motion Design
Motion communicates causality, hierarchy, and feedback. Bad motion either distracts (too much) or feels broken (too little). The defaults below produce motion that reads as designed.
Quantified Rules
Duration
| Type | Duration | Source |
|---|---|---|
| Tiny state change (hover, focus) | 100–150ms | Material 3 |
| Small (toggle, accordion item) | 200–300ms | Material 3 |
| Medium (modal open, drawer slide) | 250–400ms | Material 3 |
| Large (page transition, full-screen reveal) | 400–600ms | Material 3 |
| Loading skeleton pulse | 1000–2000ms | Common practice |
Rules:
- Smaller elements move faster. Larger elements move slower.
- Exit animations are 20–30% faster than entrances. Users want to dismiss faster than they want to receive.
- Anything over 600ms feels slow. If a transition needs to be longer, break it into stages.
- Anything under 80ms feels jarring. Below this threshold, the brain doesn't see the transition.
Easing
Default to non-linear easing for every transition. Linear easing only applies to looping animations (rotation, progress bars).
| Easing | When to use | Curve |
|---|---|---|
ease-out |
Element entering screen | cubic-bezier(0.16, 1, 0.3, 1) (sharper than CSS default) |
ease-in |
Element exiting screen | cubic-bezier(0.7, 0, 0.84, 0) |
ease-in-out |
Element moving on screen | cubic-bezier(0.65, 0, 0.35, 1) |
linear |
Loading, progress, infinite | none |
| Custom spring | Playful UI, drag-release | depends |
Why ease-out for entrances: starts fast, slows to a stop. Mimics physical objects decelerating. Element is visible quickly.
Why ease-in for exits: starts slow, accelerates away. Element is visible while leaving, then quickly gone.
Banned Easings
| Easing | Why it fails |
|---|---|
bounce, elastic |
Feels dated, distracts, overused 2014–2018 |
Default CSS ease |
Symmetric, lifeless |
linear on UI transitions |
No personality, feels mechanical |
| Long custom springs (>800ms) | Hijacks attention |
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.

canon-motion is a skill published in the GitHub repository Dragoon0x/canon (6 stars, last pushed 6mo ago), licensed MIT. It adds 75 tokens to every session and 2,413 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.
