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 | $0.00045 | $0.03893 |
| Opus 5 | $0.00023 | $0.01946 |
| Sonnet 5 | $0.00009 | $0.00779 |
| Haiku 4.5 | $0.00005 | $0.00389 |
Grade A, and why
design-tokens-structure 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 13d 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.

Design Tokens Structure
Overview
Establish the architectural foundation for a scalable design token system. Defines the three-layer token hierarchy (primitive → semantic → component) that enables theming, multi-brand support, and maintainable design systems.
When to Use
- Starting a new design system from scratch
- Restructuring an existing token system
- Adding multi-theme or multi-brand support
- Converting hardcoded values to tokens
- Creating a token governance strategy
Implementation Checklist
Copy this checklist when architecting a token system:
Token Architecture Setup:
- [ ] Audit existing values and establish naming conventions
- [ ] Define primitive tokens (raw values, context-free)
- [ ] Define semantic tokens (purpose-based, reference primitives)
- [ ] Create theme overrides (dark.json, brand variants)
- [ ] Add component tokens for complex stateful components
- [ ] Configure build output (CSS variables, Tailwind, JSON)
Quick Reference: Token Layers
| Layer | Also Called | Purpose | Example |
|---|---|---|---|
| Primitive | Core, Base, Global | Raw values, context-free | blue-500: #3b82f6 |
| Semantic | Alias, Purpose, Role | Meaning-based references | color-primary: {blue-500} |
| Component | Specific, Local | Component-scoped tokens | button-bg: {color-primary} |

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.

design-tokens-structure is a skill published in the GitHub repository dylantarre/design-system-skills (43 stars, last pushed 8mo ago), licensed MIT. It adds 45 tokens to every session and 3,893 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 2026-08-30.
