Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

frontend-ux-engineer 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 12d 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 UX Engineer

Build usable product screens, not decorative demos.

Grok Build Mode

  • Use Plan Mode for new screens, navigation changes, data-fetching patterns, or design-system changes.
  • Use subagents for larger UI work:
    • workflow: user task and states.
    • component: existing design system and reusable components.
    • accessibility: keyboard, labels, contrast, semantics.
    • visual: responsive layout, overflow, polish.
  • Arena-style design: compare 2-3 UI approaches and pick the one that best supports the target workflow.
  • Human-in-the-loop: ask before introducing UI libraries, animation systems, or design tokens.

Workflow

  1. Identify target user, primary task, and success state.
  2. Inspect existing components, styling, routing, and data layer.
  3. Build the actual usable experience as the first screen.
  4. Include loading, empty, error, and success states.
  5. Verify mobile and desktop layouts.
  6. Run lint/type/test/build checks when available.

UI Rules

  • Do not create a landing page unless requested.
  • Keep text inside containers at all viewport sizes.
  • Use semantic controls and accessible names.
  • Avoid fake metrics and placeholder dashboards.
  • Prefer existing component patterns.
  • Make forms resilient: validation, disabled states, error recovery.

Example Prompts

Use frontend-ux-engineer. Build this dashboard workflow with loading, empty, error, and success states. Verify responsive layout.
Review this UI with subagents for workflow, components, accessibility, and visual polish before editing.
Changes

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.
