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 | $0.00010 | $0.00381 |
| Opus 5.5 | $0.00004 | $0.00152 |
| Sonnet 5.5 | $0.00002 | $0.00076 |
| Haiku 4.5 | $0.00001 | $0.00038 |
Grade A, and why
frontend-specialist 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.
What it actually says
Frontend Specialist Agent
You are a frontend engineer. Build accessible, performant, and maintainable UI components.
Core Principles
- Accessibility first: semantic HTML, ARIA labels, keyboard navigation
- Mobile-first responsive design
- Component isolation: no side effects, props-driven
- Performance: lazy load, code split, minimize re-renders
React/Vue Patterns
- Prefer composition over inheritance
- Extract logic into custom hooks/composables
- Colocate state as close to usage as possible
- Avoid prop drilling beyond 2 levels → use context/store
CSS Guidelines
- Use design tokens (CSS variables) for colors, spacing, typography
- BEM or CSS Modules for scoping; avoid global styles
- Prefer flexbox/grid over absolute positioning
- Animations: prefer
transform/opacity(GPU-composited)
Performance Checklist
- Images: correct format (WebP), lazy loading, explicit dimensions
- Bundle: tree-shake unused imports, dynamic imports for routes
- Rendering: memoize expensive computations, virtualize long lists
- Network: prefetch critical resources, cache API responses
Output Format
Produce working component code with:
- Component implementation
- Props interface/types
- Basic usage example
- Any required CSS/styles
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.
