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 | $0.00099 | $0.02081 |
| Opus 5 | $0.00049 | $0.01040 |
| Sonnet 5 | $0.00020 | $0.00416 |
| Haiku 4.5 | $0.00010 | $0.00208 |
Grade A, and why
colors 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 4d 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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Color that carries meaning
OKLCH is a perceptually uniform color space where lightness, chroma, and hue are useful design controls. Use it when the project already uses OKLCH, when creating a new color system, or when the user asks for conversion or palette work. Otherwise preserve the project's established tokens and notation: a consistent hex or RGB token system is better than introducing a second color representation for an isolated fix.
Core Principles
1. Use a Perceptual Color Space
- Respect the existing system. Do not convert notation merely because this skill was loaded. Reuse the project's semantic tokens and authoring format unless the task includes a color-system migration.
- Color carries one meaning. A hue that means "link" cannot also be decoration, and a semantic token is never borrowed by value for a role it doesn't name. →
references/color-usage.md— semantic-token roles, one-meaning-per-color, primary-action emphasis, and light/dark appearance variants, read when this change assigns a color to a role or adds a control's color treatment. - Perceptual uniformity. Equal L steps = equal brightness.
oklch(0.5 ...)is visually mid. HSL'slightness: 50%varies wildly by hue. - Stable hue. HSL blue shifts toward purple as lightness changes. OKLCH hue stays constant across the full lightness range.
- Independent chroma. Chroma is an absolute measure of colorfulness that doesn't depend on lightness. HSL saturation does.
- Finite gamut. Not every oklch value maps to a displayable sRGB color. High-chroma values at certain hues will clip; gamut awareness is required.
2. Write and Format OKLCH Consistently
oklch(L C H)
oklch(L C H / alpha)
| Channel | Range | Description |
|---|---|---|
| L (Lightness) | 0–1 | 0 = black, 1 = white. Perceptually uniform. |
| C (Chroma) | 0–~0.4 | Colorfulness. 0 = gray. Max depends on L and H. |
| H (Hue) | 0–360 | Hue angle in degrees. |
| alpha | 0–1 | Optional transparency. Slash syntax. |
What ships with it
5 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.

colors is a skill published in the GitHub repository PrabhdeepSingh/claude-plugins (3 stars, last pushed 5d ago), licensed MIT. It adds 99 tokens to every session and 2,081 once invoked, about $0.0005 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 2026-08-31.
