Antigravity Agent c24165b8bc refactor(topics): 멀티 에이전트용 지식 재편 — _Common(공통 기본기) + Domain_* 구조
에이전트 8종(대화형/프로그래머 C·S/디자이너/설계자/기획자/QA/PD/PM)에게
[공통 기본 능력 + 롤별 Specialty] 2층으로 지식을 주입하기 위한 재분류.
문서 내용·포맷은 무수정, 폴더 이동만 (6,372개 문서 수 보존 확인).

- Topic_Programming → Domain_Programming (내부 구조 보존)
- Topic_Graphic → Domain_Design
- Topic_Business → Domain_Product
- Topic_General → Domain_General
- _Common 신설: Math(구 Topic_Math_Specialty), Reasoning(구 General/From_Thinking & Reasoning),
  Reasoning_Creativity(구 General/From_창의성), Communication(Poetic_Blog_Writing + From_writing)
- 타 도메인의 From_* 폴더는 유지 (출처 표기일 뿐, 이미 도메인에 맞게 분류된 문서)
- 빈 폴더 정리 (memory/procedures)
- 에이전트→폴더 매핑은 workspace의 .astra/agent-knowledge-map.json (9개 에이전트)

Interaction to Next Paint (INP)

매 한 줄

"매 user input → 매 next visible paint 의 latency". 2024-03 의 의 의 FID 의 replace. 매 Core Web Vitals member. 매 < 200ms 'good', < 500ms 'needs improvement'.

매 핵심

매 measurement

  • 매 매 page session 의 of 의 모든 interaction 의 worst (P98).
  • 매 input delay + processing + presentation delay.

매 응용

  • SEO (Google ranking).
  • UX.
  • Form / button responsiveness.

💻 패턴

Measure

import { onINP } from 'web-vitals';
onINP(({ value, rating }) => {
  analytics.track('INP', { value, rating });  // 매 rating: 'good' | 'needs-improvement' | 'poor'
});

Optimize: yield to main thread

button.addEventListener('click', async () => {
  await scheduler.yield();  // 매 modern API
  // 매 매 chunk 의 의 의 yield
  for (let i = 0; i < items.length; i++) {
    if (i % 100 === 0) await scheduler.yield();
    process(items[i]);
  }
});

Web Worker (heavy work)

const worker = new Worker('heavy.js');
button.addEventListener('click', () => {
  worker.postMessage(data);
});
worker.onmessage = e => updateUI(e.data);

Debounce / throttle

function debounce(fn, ms) {
  let timer;
  return (...args) => {
    clearTimeout(timer);
    timer = setTimeout(() => fn(...args), ms);
  };
}

input.addEventListener('input', debounce(handleSearch, 300));

React 18 useDeferredValue

function Search({ query }) {
  const deferredQuery = useDeferredValue(query);
  const results = expensiveCompute(deferredQuery);
  return <Results items={results} />;
}

Long Animation Frames API (debug)

new PerformanceObserver(list => {
  for (const entry of list.getEntries()) {
    if (entry.duration > 50) {
      console.warn('Long task', entry);
    }
  }
}).observe({ type: 'long-animation-frame', buffered: true });

Code splitting

const HeavyComponent = lazy(() => import('./HeavyComponent'));
// 매 only loaded on demand

매 결정 기준

상황 Approach
Heavy compute Worker
Long task scheduler.yield
Search input Debounce + useDeferredValue
Initial bundle Code split

기본값: 매 measure with web-vitals + 매 yield + 매 worker for heavy + 매 < 200ms target.

🔗 Graph

🤖 LLM 활용

언제: 매 web product. 매 SEO. 언제 X: 매 backend.

안티패턴

  • Synchronous heavy work on main thread: 매 INP 폭발.
  • No measurement: 매 invisible.
  • setTimeout(0) only: 매 still on main.

🧪 검증 / 중복

  • Verified (web.dev, web-vitals.js docs).
  • 신뢰도 A.
