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 | $0.00055 | $0.01696 |
| Opus 5 | $0.00028 | $0.00848 |
| Sonnet 5 | $0.00011 | $0.00339 |
| Haiku 4.5 | $0.00006 | $0.00170 |
Grade A, and why
ckm:design-system 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 9d 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.
This is a copy
100% identical to design-system — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Design System
Token architecture, component specifications, systematic design, slide generation.
When to Use
- Design token creation
- Component state definitions
- CSS variable systems
- Spacing/typography scales
- Design-to-code handoff
- Tailwind theme configuration
- Slide/presentation generation
Token Architecture
Load: references/token-architecture.md
Three-Layer Structure
Primitive (raw values)
↓
Semantic (purpose aliases)
↓
Component (component-specific)
Example:
/* Primitive */
--color-blue-600: #2563EB;
/* Semantic */
--color-primary: var(--color-blue-600);
/* Component */
--button-bg: var(--color-primary);
Quick Start
Generate tokens:
node scripts/generate-tokens.cjs --config tokens.json -o tokens.css
Validate usage:
node scripts/validate-tokens.cjs --dir src/

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.

ckm:design-system is a skill published in the GitHub repository S3YED/appie-kit (9 stars, last pushed 17d ago), licensed MIT. It adds 55 tokens to every session and 1,696 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to design-system, differing in 6 lines, and is treated as a copy.
