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 | $0.00123 | $0.03052 |
| Opus 5 | $0.00062 | $0.01526 |
| Sonnet 5 | $0.00025 | $0.00610 |
| Haiku 4.5 | $0.00012 | $0.00305 |
Grade A, and why
color-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 12d 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.

Color in Motion
Choose, pair, and animate color for motion design: building restrained palettes, constructing gradients that read as premium, interpolating colors in perceptually-uniform spaces, and grading a piece for mood and consistency. Produces palettes with exact OKLCH/hex values, gradient CSS/code, and transition parameters.
When to use
- Picking or pairing a palette for a motion or video piece.
- Building gradient backgrounds (mesh, noise, animated drift).
- Animating color transitions (button states, theme switch, loaders).
- Grading a video for mood, or fixing dull/gray gradient interpolation.
- Fixing washed-out, gamma-shifted, or platform-inconsistent After Effects renders, and choosing correct per-platform export/color tags.
Core techniques
1. Build a restrained palette
Limit hues. A strong motion palette is 1 primary + 1 accent + 2-3 neutrals. Derive contrast and depth from lightness and chroma, not from adding more hues. Extra hues fight for attention and read as amateur.
In dark scenes, make the accent pop with low-to-moderate chroma and high lightness rather than maximum saturation — a blown-out saturated accent vibrates and looks cheap on dark backgrounds.
Use OKLCH to reason about color: oklch(L C H) where L is perceptual lightness (0-1), C is chroma (0 ≈ 0.37 max), H is hue angle (0-360). Holding L and C constant while rotating H gives hues of genuinely equal visual weight — impossible to do reliably in HSL.
Primary: oklch(0.62 0.19 264) /* confident blue */
Accent: oklch(0.78 0.17 50) /* warm amber, lighter so it pops */
Neutral-0: oklch(0.97 0.005 264) /* near-white, faint hue tint */
Neutral-1: oklch(0.55 0.01 264)
Neutral-2: oklch(0.18 0.015 264) /* near-black, same hue family */
Tinting neutrals slightly toward the primary hue (tiny chroma) unifies the frame; pure gray neutrals next to colored elements look disconnected.
2. Interpolate in OKLCH or Lab — never raw sRGB
Linearly interpolating two colors in sRGB passes through a desaturated, often gray or muddy midpoint (blue->yellow goes through gray; blue->red through muddy purple). Perceptual spaces (OKLCH, OKLab, CIE Lab) keep midpoints vivid and lightness even.
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.
- 12d ago First seen · 176 lines · 123 tokens per session scan A 8c7fcf06c25e
color-motion is a skill published in the GitHub repository iart-ai/motion-design-skills (29 stars, last pushed 2mo ago), licensed MIT. It adds 123 tokens to every session and 3,052 once invoked, about $0.0006 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.
