frontend-guidelines

frontend-guidelines is a skill for Claude Code, Codex from Oriolshhh/runware-image-mcp. It costs 22 tokens per session (779 once invoked), scanned A, original, MIT.

A set of guidelines for building and reviewing rendered frontend interfaces, including components, forms, navigation, client state, responsive behavior, accessibility, and browser interactions.

In plain words
What is it for?
Use it when implementing or reviewing frontend UI, including loading, empty, success, error, permission, offline, validation, responsive, animation, and accessibility states.
Why use it?
It helps prevent tangled components, incomplete loading or error handling, keyboard problems, and interfaces that conflict with the product's design system.

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-guidelines 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 5d 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.

Frontend Guidelines

Purpose

Keep frontend implementation usable, accessible, maintainable, and coherent with the product's design system instead of accumulating fragile component spaghetti.

When to use it

  • Implementing or reviewing rendered UI, routes, components, client state, forms, navigation, design-system usage, or visual behavior.
  • Changing loading, empty, error, success, permission, or offline states.
  • Adding responsive behavior, animation, browser interactions, or accessibility behavior.
  • Improving an existing interface through /frontend-design, /improve-ui-ux, /ui-review, or frontend tasks inside /implement.

Instructions

  1. Reuse existing design tokens, primitives, layout patterns, and component conventions before creating new styles or components.
  2. Separate responsibilities: data loading, state transitions, presentation, form validation, and side effects should not collapse into one tangled component when they change for different reasons.
  3. Model the full state matrix: loading, empty, success, error, validation, permission, disabled, optimistic/pending, and long-content states.
  4. Build semantic, keyboard-operable UI first. Controls need names, roles, focus order, visible focus, labels, error association, and recoverability.
  5. Make layout content-driven and responsive. Verify mobile, tablet/desktop, zoom/reflow, long text, missing media, and narrow containers.
  6. Keep client state minimal and colocated. Lift state only when multiple owners truly need it; avoid duplicating server/cache state in local component state.
  7. Preserve performance basics: avoid unnecessary rerenders, unbounded effects, layout thrash, oversized bundles, and client-only work that could stay server side in the repository's framework.
  8. Use motion only when it communicates state or improves comprehension. Respect reduced motion and avoid blocking interaction.
  9. Validate in a real browser for user-facing changes. Check relevant viewports, states, keyboard paths, console errors, network failures, and screenshots when visual quality matters.
  10. Add tests where stable: component/interaction tests for behavior, integration tests for flows, and visual/browser evidence for presentation-sensitive work.

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.
