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 | $0.00078 | $0.01801 |
| Opus 5 | $0.00039 | $0.00901 |
| Sonnet 5 | $0.00016 | $0.00360 |
| Haiku 4.5 | $0.00008 | $0.00180 |
Grade A, and why
uiux-frontend-engineering 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.

UIUX Frontend Engineering
Core Rule
Treat UI as a tested product interface, not decoration: connect user goals, business goals, interaction model, visual system, implementation constraints, and validation evidence before shipping screens or components.
First Pass
- Classify the task: UX strategy, research, persona, UX mapping, IA/sitemap, user flow, wireframe, prototype, mockup, UI pattern selection, visual UI, design system, frontend stack/library selection, frontend implementation, responsive/mobile, accessibility, redesign/review, handoff, or XR/spatial interface.
- Identify target surface: web, mobile web, native mobile, desktop web app, kiosk, embedded screen, WebXR, VR, AR, MR, or spatial computing.
- Name users, context, primary jobs, failure modes, conversion or task metric, platform constraints, input method, and trust/safety concerns.
- Decide fidelity: sketch/flow, low-fidelity wireframe, clickable prototype, high-fidelity visual, coded prototype, production component, or XR graybox.
- Select validation before implementation: heuristic review, accessibility audit, responsive screenshots, usability test, click/first-impression test, A/B test, performance check, or XR comfort review.

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.
