frontend-design

frontend-design is a skill for Claude Code, Codex from ceilf6/FrontAgent. It costs 62 tokens per session (798 once invoked), scanned A, original, MIT.

A design guide for building or restyling frontend interfaces—the screens and controls users see in a web application. It focuses on a clear visual direction, production-ready code, and respecting existing design rules.

In plain words
What is it for?
Use it for landing pages, dashboards, product pages, hero sections, marketing sites, and polished application views when visual design is part of the work.
Why use it?
It helps prevent new pages from looking generic or conflicting with the product's existing design. It also sets boundaries for changes when the project already has design specifications.

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-design 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 4d 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 Design

Use this skill to produce frontend work that feels intentionally designed rather than generic. The goal is not maximalism by default. The goal is a clear visual point of view that matches the product context and still ships as maintainable code.

Trigger

  • New frontend surfaces where look and feel matter:
    • landing pages
    • dashboards
    • product pages
    • hero sections
    • marketing sites
    • polished application views
  • Requests to beautify, restyle, refine, or modernize an existing UI
  • Cases where the code must be working and production-usable, not just a mockup

Do Not Use

  • Pure bug fixes, refactors, or backend tasks
  • Review or audit requests
  • Small code changes where the user did not ask for visual improvement
  • Existing design-system work where the user only wants strict conformance and no meaningful visual interpretation

Workflow

  1. If the request is visually underspecified, ask only the next 1-3 questions needed to clarify audience, tone, and acceptance criteria. Use requirement-interviewer when the ambiguity is material.
  2. Read references/design-direction.md to choose one clear visual direction before coding.
  3. Read references/aesthetics-guidelines.md for typography, color, motion, composition, and background treatment.
  4. Read references/integration-guardrails.md before modifying an existing codebase, design system, or shared component surface.
  5. For a new page or major redesign, use assets/templates/visual-brief.md to form a short visual brief before implementation.
  6. Implement working code that matches the chosen direction and stays within project constraints.
  7. Read references/delivery-checks.md before handing off.

Output Contract

  • State the chosen visual direction in one short sentence when it meaningfully affects implementation.
  • Produce working frontend code, not mood-board prose.
  • Keep the implementation cohesive:
    • typography should support the direction
    • color should feel intentional
    • motion should be meaningful, not noisy
    • layout should feel composed rather than assembled from defaults
  • When editing an existing product, preserve the established system unless the user explicitly wants a stronger redesign.

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.
