Mimikyu: Instructions file for Codex

AGENTS.md

Mimikyu AGENTS.md is an instructions file for Codex, OpenCode from 3x-haust/Mimikyu. It costs 3,811 tokens per session, scanned A, a copy of Mimikyu CLAUDE.md, MIT.

Project instructions for recreating Figma designs as React and Tailwind CSS interfaces. Figma is a design tool; pixel comparison checks whether the result looks like the design.

In plain words
What is it for?
They guide Figma data extraction, React and Tailwind implementation, screenshots, and image-based visual checks.
Why use it?
They give an agent a defined workflow and project conventions instead of making it decide how to extract, build, and compare the design each time.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is 3x-haust/Mimikyu's own configuration. It tells Codex and OpenCode how to work on Mimikyu itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Mimikyu configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is PORT=<port> npx tsx ../../scripts/screenshot.ts screenshots/v1.png <width> <height>.

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

Mimikyu AGENTS.md scanned grade A with 1 finding 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 yesterday.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Mimikyu (따라큐) - Figma Pixel Perfect Publisher

개요

Figma 디자인을 픽셀 퍼펙트하게 React + Tailwind CSS로 재현하는 도구. Figma MCP (Framelink + 공식)로 디자인 데이터를 추출하고, Playwright + PIL로 픽셀 단위 검증 루프를 돌린다.

프로젝트 구조

Mimikyu/
├── scripts/           # 공용 스크립트 (screenshot.ts, compare.py, mimikyu.ts, verify.ts)
└── <각 프로젝트>        # 폴더 구조 강제 없음 (아래 참조)

폴더 구조를 강제하지 않는다.

  • 사용자가 경로/기존 프로젝트/폴더 규칙을 주면 → 그대로 따른다 (기존 컨벤션을 존중, 엉뚱한 폴더 추가 금지).
  • 아무 정보가 없으면 → AI가 합리적인 구조를 스스로 정하고 진행한다. 물어보지 않고 진행 (예: 스택 네이티브 스캐폴드 + 앱 옆 designs/screenshots/diffs).
  • 사용자 정보 > AI 자율 판단.

기술 스택

  • React 19 + TypeScript + Tailwind CSS v4 (@tailwindcss/vite) + Vite
  • Playwright (headless Chromium 스크린샷)
  • Python PIL/Pillow (픽셀 비교 + 히트맵)
  • pnpm
  • Figma MCP 서버:
    • Framelink (framelink-figma) — get_figma_data, download_figma_images
    • 공식 Figma (figma) — view_node, add_figma_file, read_comments

워크플로우

Phase 1: Figma 디자인 데이터 추출 및 저장

MCP 도구를 사용하여 Figma 데이터를 가져오고, designs/figma-data.json에 저장한다. 이후 검증 루프에서는 MCP를 다시 호출하지 않고 이 파일을 참조하여 수정한다.

1. Framelink MCP — 디자인 구조 + 스타일 데이터
mcp__framelink-figma__get_figma_data(
  fileKey: "<FILE_KEY>",
  nodeId: "<NODE_ID>"    // URL의 node-id 파라미터
)
  • 레이아웃 구조, 스타일, 좌표, 타이포그래피 등 전체 디자인 데이터 반환
  • depth 옵션으로 트리 탐색 깊이 제어 가능
2. Framelink MCP — 이미지 에셋 다운로드
mcp__framelink-figma__download_figma_images(
  fileKey: "<FILE_KEY>",
  nodeId: "<NODE_ID>",
  outputDir: "public/assets/"
)
  • 아이콘, 일러스트 등 이미지 에셋을 로컬에 다운로드
3. 공식 Figma MCP — 노드 시각 확인
mcp__figma__view_node(
  file_key: "<FILE_KEY>",
  node_id: "<NODE_ID>"   // "1:46" 형식
)
  • 특정 노드의 썸네일 이미지 확인용
Figma URL 파싱
https://www.figma.com/design/<FILE_KEY>/Title?node-id=<NODE_ID>

추출할 데이터:

  • absoluteBoundingBox → 각 요소의 정확한 x, y, width, height
  • fills → 배경색, 그라디언트
  • style → font-family, font-size, font-weight, line-height, letter-spacing
  • cornerRadius → border-radius
  • effects → box-shadow
  • strokes → border

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.
