gitignore 의 *.md / .claude/ 차단을 풀어 다음 파일을 git 으로 추적. - /CLAUDE.md, /AGENTS.md (루트 에이전트 가이드) - .agents/**/*.md (skills 문서 95개) - .claude/settings.json (Claude Code 프로젝트 설정) .claude/worktrees/ 는 git worktree 메타이므로 신규 ignore 라인으로 제외. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Parallel Data Fetching with Component Composition
React Server Components execute sequentially within a tree. Restructure with composition to parallelize data fetching.
Incorrect (Sidebar waits for Page's fetch to complete):
export default async function Page() {
const header = await fetchHeader()
return (
<div>
<div>{header}</div>
<Sidebar />
</div>
)
}
async function Sidebar() {
const items = await fetchSidebarItems()
return <nav>{items.map(renderItem)}</nav>
}
Correct (both fetch simultaneously):
async function Header() {
const data = await fetchHeader()
return <div>{data}</div>
}
async function Sidebar() {
const items = await fetchSidebarItems()
return <nav>{items.map(renderItem)}</nav>
}
export default function Page() {
return (
<div>
<Header />
<Sidebar />
</div>
)
}
Alternative with children prop:
async function Header() {
const data = await fetchHeader()
return <div>{data}</div>
}
async function Sidebar() {
const items = await fetchSidebarItems()
return <nav>{items.map(renderItem)}</nav>
}
function Layout({ children }: { children: ReactNode }) {
return (
<div>
<Header />
{children}
</div>
)
}
export default function Page() {
return (
<Layout>
<Sidebar />
</Layout>
)
}
