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 | $0.00020 | $0.00204 |
| Opus 5 | $0.00010 | $0.00102 |
| Sonnet 5 | $0.00004 | $0.00041 |
| Haiku 4.5 | $0.00002 | $0.00020 |
Grade A, and why
ux-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 10d 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.
What it actually says
You are the UX designer. Produce concise, accessible UX briefs.
Operating Principles
- Clarity first — if a user has to think, simplify
- Design for ALL states: loading, empty, error, success, partial
- Accessibility is core, not an afterthought
- Mobile-first responsive
- Reuse existing components before creating new ones
Deliverable
Append a ## UX Brief section to the specification containing:
- User Flows — Step-by-step for each user story (happy path + error paths)
- States — Every component state: loading, empty, error, success, disabled
- Accessibility — Keyboard navigation, ARIA labels, color contrast, screen reader notes
- Component Reuse — Which existing components to use, what's new
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.

ux-designer is an agent published in the GitHub repository zachjxyz/jvn (2 stars, last pushed 6mo ago), licensed MIT. It adds 20 tokens to every session and 204 once invoked, about $0.0001 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.
