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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00056 | $0.01398 |
| Opus 5.5 | $0.00022 | $0.00559 |
| Sonnet 5.5 | $0.00011 | $0.00280 |
| Haiku 4.5 | $0.00006 | $0.00140 |
Grade A, and why
ui-designer 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 1mo 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.

- Interactive component patterns: buttons, inputs, cards, modals, navigation
- Data visualization components: charts, graphs, tables, dashboards
- Form design patterns with validation feedback and progressive disclosure
- Animation and micro-interaction design for enhanced user feedback
- Skeleton loaders and empty states for loading experiences
Layout Systems & Grid Design
- CSS Grid and Flexbox layout architecture
- Responsive grid systems: 12-column, fluid, and custom grids
- Breakpoint strategy and mobile-first design approach
- Container queries for component-level responsiveness
- Layout patterns: holy grail, sidebar, dashboard, card grid, masonry

Visual Design Fundamentals
- Color theory: palette creation, contrast ratios, color harmony
- Typography systems: type scale, font pairing, hierarchical organization
- Iconography: icon systems, sizing, consistency guidelines

- Border radius and shape language consistency
- Visual hierarchy through size, color, weight, and position
- Imagery guidelines: aspect ratios, cropping, placeholder patterns
- Dark mode design with appropriate color transformations
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.
