web-preview-guide

web-preview-guide is an agent for coding agents from Dannykkh/skill-olympus. It costs 52 tokens per session (4,567 once invoked), scanned A, original, MIT.

A legacy reference guide for web preview mode, written in Korean.

In plain words
What is it for?
Use it only when someone explicitly asks for this guide while working on web preview mode.
Why use it?
It provides background for older preview workflows, but the description says current work should follow the project’s AGENTS.md and DESIGN.md files first.

Agent

Part of the skill-olympus plugin — 13 skills, 2 commands, 41 agents shipped together

Install

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.

agentmods
npx agentmods add agents/dannykkh/skill-olympus/web-preview-guide
Clone the repo
git clone --depth 1 https://github.com/Dannykkh/skill-olympus

Or install skill-olympus, the plugin that ships this one along with the rest of its 13 skills, 2 commands, 41 agents.

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

web-preview-guide 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 3d 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.

Web Preview Mode Development Guide (Legacy Reference)

현재 정본은 루트 AGENTS.md의 프론트엔드 가드레일과 프로젝트 DESIGN.md입니다. 이 문서는 과거 PreviewPanel 상세 흐름이 필요한 경우에만 참고합니다. 웹 프리뷰 모드(채팅 모드 + dev server + PreviewPanel)에서 개발할 때 아래 순서를 따릅니다. 사용자가 다른 순서를 명시적으로 요청하면 그에 따릅니다.


Phase 0: Design DNA (디자인 토큰 먼저)

100개 이상 화면에서 일관성을 유지하려면, 토큰 없이 바로 화면부터 시작하면 안 된다. 아토믹 단위의 디자인 DNA를 먼저 제작해야 한다.

젭마인 연동: claude-interview.md의 Category B(디자인 비전)에서 수집한 벤치마킹 URL, 톤/무드, 색상 선호가 있으면 그것을 입력으로 사용합니다. 젭마인은 "어떤 느낌을 원하는가"를 수집하고, 여기서는 그 레퍼런스의 실제 시각 요소(색상, 간격, 그림자)를 추출하여 토큰으로 만듭니다.

Step 0. 디자인 방향성 잡기 (리서치)

프로젝트의 산업/목적에 맞는 디자인 방향성을 검색해서 결정합니다.

0-1. 산업별 트렌드 검색:

WebSearch로 "{산업} website design trends 2025" 검색
→ 해당 산업에서 어떤 스타일이 주류인지 파악
→ 예: "SaaS dashboard design trends" / "뷰티 스파 웹사이트 디자인"

0-2. 경쟁사/벤치마킹 사이트 탐색:

WebSearch로 "{산업} best website examples" 검색
→ top 3~5개 사이트 URL 확보
→ Playwright로 각 사이트에 접속해서 스크린샷 자동 캡처:

  browser_navigate → "{경쟁사 URL}"
  browser_take_screenshot → "competitor-1.png"

0-3. 방향성 결정표 작성:

항목 리서치 방법 예시
UI 스타일 검색 트렌드 + 경쟁사 분석 Glassmorphism, Soft UI, Minimalism 등
컬러 무드 경쟁사 스크린샷에서 추출 SaaS → 블루/퍼플, 헬스케어 → 그린/화이트
타이포그래피 Google Fonts 트렌드 검색 Pretendard + Inter, Noto Sans KR + Roboto
레이아웃 패턴 경쟁사 공통 패턴 분석 Hero-Centric, Feature Showcase, Dashboard
안티패턴 산업별 부적절한 것 금융앱에 네온 컬러, AI 제품에 보라+핑크 그라디언트

참고: ui-ux-pro-max 스킬이 설치되어 있으면 --design-system 옵션으로 산업별 100개 규칙 기반 자동 생성 가능.

Step 1. 레퍼런스 수집 + 디자인 토큰 생성

1-1. 레퍼런스 이미지 수집 (3가지 경로):

경로 방법
사용자 제공 리뉴얼 대상, 영감 이미지를 직접 전달
자동 캡처 Step 0에서 찾은 경쟁사/벤치마킹 사이트를 Playwright로 스크린샷
디자인 갤러리 검색 WebSearch로 Dribbble, Behance, Awwwards에서 "{산업} UI" 검색 → 상위 결과 참고
# 자동 캡처 예시 (Playwright MCP)
browser_navigate → "https://경쟁사1.com"
browser_take_screenshot → fullPage: true, filename: "ref-competitor-1.png"

browser_navigate → "https://레퍼런스사이트.com"

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.
