frontend-design

frontend-design is a skill for Claude Code, Codex from AnthonyPoschen/agent-skills. It costs 137 tokens per session (4,543 once invoked), scanned A, original, MIT.

A guide for designing and building polished web interfaces such as apps, dashboards, tools, landing pages, and responsive components.

In plain words
What is it for?
It helps with frontend design, redesigns, visual reviews, responsive workflows, design systems, and recording important design decisions in DESIGN.md.
Why use it?
It ties layout, styling, typography, color, and interface structure to the user's task instead of treating isolated components as a finished design.

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.

How it starts

The opening of the file, as written. The whole thing — 411 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Frontend Design

Create interfaces that make a real task easy to understand and complete. Make visual choices serve the product and its users; do not treat a collection of components as a finished design.

Design Consultation

When consulted before implementation, establish the few decisions that coding cannot safely infer. Do not block a small, reversible change for a full brief; use repository evidence and state reasonable assumptions. Ask only when an unknown would materially change the workflow, content priority, or visual direction.

Treat DESIGN.md in the target project as the durable record of design knowledge. Look for it before making a material design decision. At the first substantive design consultation, create it if it does not exist. Update it when user feedback, repository evidence, testing, or a design review changes an assumption, constraint, priority, or decision. Record the decision and its reason, not a transcript of the conversation.

Capture these decisions when the work is substantial, likely to span multiple sessions, or needs handoff to another implementer:

  • Outcome and success: the user outcome, the primary action or decision, and how the team will know the design worked.
  • Audience and context: who uses it, their familiarity and urgency, the device or environment, and any access needs that shape the interaction.
  • Primary workflow: entry point, happy path, key alternatives, and the feedback or recovery needed after success, failure, or interruption.
  • Content and data: the real information, its relative importance, expected density, long or empty values, and any content that must remain visible.
  • States and rules: permissions, validation, loading, empty, error, destructive, selected, and time-sensitive states that change what a person can see or do.
  • Constraints: existing design system or product conventions, technical limits, supported viewports and input methods, accessibility requirements, brand constraints, and licensed assets or fonts.
  • Visual direction: a few concrete adjectives, comparable product references, and anti-references that clarify the desired character without copying another product.
  • Scope and tradeoffs: what is deliberately out of scope, what can be a sensible default, and which unresolved questions need a prototype or user decision.

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.
