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 | $0.00045 | $0.03071 |
| Opus 5 | $0.00023 | $0.01536 |
| Sonnet 5 | $0.00009 | $0.00614 |
| Haiku 4.5 | $0.00005 | $0.00307 |
Grade A, and why
color-tools 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 3d 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 Tools Skill
This skill helps you create accessible, harmonious color palettes and ensures your colors meet WCAG contrast requirements. I provide color calculations, palette generation, and accessibility validation.
What I Can Do
Color Contrast Checking
- Calculate contrast ratios
- Verify WCAG AA/AAA compliance
- Suggest accessible alternatives
- Check text/background combinations
Palette Generation
- Create tint/shade scales (50-900)
- Generate color harmonies
- Build complementary palettes
- Design theme variations
Color Conversions
- HEX ↔ RGB ↔ HSL
- Calculate opacity variations
- Generate CSS custom properties
- Create color tokens
Accessibility Tools
- Find accessible color pairs
- Suggest minimum contrast fixes
- Validate interactive state colors
- Check large text requirements
WCAG Contrast Requirements
Minimum Ratios
- Normal text: 4.5:1 (AA), 7:1 (AAA)
- Large text (18px+ or 14px+ bold): 3:1 (AA), 4.5:1 (AAA)
- UI components: 3:1 (AA)
- Graphical objects: 3:1 (AA)
Contrast Formula
Contrast Ratio = (L1 + 0.05) / (L2 + 0.05) Where L1 is lighter color luminance and L2 is darker
Example: Contrast Checking
You: "Check if #3b82f6 on white background is accessible"
I'll provide:
Color: #3b82f6 (Blue)
Background: #ffffff (White)
Contrast Ratio: 4.52:1
WCAG Compliance:
✓ Normal text AA (4.5:1 required) - PASS
✗ Normal text AAA (7:1 required) - FAIL
✓ Large text AA (3:1 required) - PASS
✓ Large text AAA (4.5:1 required) - PASS
✓ UI Components (3:1 required) - PASS
Recommendation:
For AAA compliance with normal text, use #2563eb (darker blue)
New contrast: 7.02:1 - Passes all requirements
Palette Generation
Tint & Shade Scale
/* Generate 50-900 scale from base color */
:root {
/* Base color: #3b82f6 */
--color-blue-50: #eff6ff; /* 90% lighter */
--color-blue-100: #dbeafe; /* 80% lighter */
--color-blue-200: #bfdbfe; /* 60% lighter */
--color-blue-300: #93c5fd; /* 40% lighter */
--color-blue-400: #60a5fa; /* 20% lighter */
--color-blue-500: #3b82f6; /* Base */
--color-blue-600: #2563eb; /* 20% darker */
--color-blue-700: #1d4ed8; /* 40% darker */
--color-blue-800: #1e40af; /* 60% darker */
--color-blue-900: #1e3a8a; /* 80% darker */
}
/* Usage guide:
* 50-100: Backgrounds, subtle highlights
* 200-300: Hover states, borders
* 400-600: Primary UI, text on light backgrounds
* 700-900: Text, emphasis, dark themes

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.

color-tools is a skill published in the GitHub repository andronics/claude-plugin-css-pro (2 stars, last pushed 10mo ago), licensed MIT. It adds 45 tokens to every session and 3,071 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 2026-08-31.
