🎯 What: Extracted the internal render blocks (Avatar, Bio, Stats, TopLanguages, and TopRepos) from the monolithic BusinessCard.tsx component into their own separate files within a new src/components/business-card directory.
💡 Why: BusinessCard.tsx was over 340 lines long and highly complex. Breaking it down into modular, single-responsibility components significantly improves maintainability and readability.
Verification: Verified by ensuring npm run lint and npm run test pass perfectly. The rendering logic remains identical to preserve UI structure.
Result: The BusinessCard.tsx file is cleaner and delegating rendering concerns out, while individual block implementations are isolated and easier to maintain.

Greptile Summary

BusinessCard 内の5つの描画ブロックを専用コンポーネントへ分割するリファクタリングです。ただし、未処理ブロックのフォールバック変更により既定カードの出力が変わります。

  • アバター、プロフィール詳細、統計、言語・トピック、リポジトリ表示を個別コンポーネントへ抽出
  • BusinessCard はレイアウト選択と子コンポーネントへのデータ配布を担当
  • 未処理の既知ブロック ID は空表示になるよう変更

Confidence Score: 4/5

既定カードから主要な表示内容が消えるため、このフォールバック回帰を修正してからマージすべきです。

現在の既定レイアウトには新しい renderBlock が処理しない既知 ID が複数含まれ、標準プレビューと PNG エクスポートでそれらが空要素として描画されます。

High-Level Assessment

The chosen decomposition into per-block components is the most maintainable approach while preserving behavior. Alternatives like keeping inline helper render functions or extracting only some blocks reduce file churn but don’t address the core readability/ownership problem as effectively.

Action required

1. Unhandled blocks render nothing 🐞 Bug ≡ Correctness
Description
BusinessCard.renderBlock returns null for valid CardBlockId values like "profile", "contributions",
"heatmap", "interests", and "skills", so those layout sections render no content. Since
DEFAULT_CARD_LAYOUT includes these IDs as visible full-column blocks (and layout normalization
re-adds them), the default/normalized BusinessCard output can silently drop entire sections.
Code

src/components/BusinessCard.tsx[R32-56]

  const renderBlock = (blockId: CardBlockId) => {
    if (blockId === "avatar") {
-      return renderAvatarBlock();
+      return <AvatarBlock profile={profile} />;
    }
    if (blockId === "bio") {
-      return renderBioBlock();
+      return <BioBlock profile={profile} options={options || {}} />;
    }
    if (blockId === "stats") {
-      return renderStatsBlock();
+      return <StatsBlock profile={profile} contributions={contributions} options={options || {}} />;
    }
    if (blockId === "topLanguages") {
-      return renderTopLanguagesBlock();
+      return (
+        <TopLanguagesBlock
+          topLanguages={topLanguages}
+          topTopics={topTopics}
+          interests={interests}
+          activity={activity}
+          options={options || {}}
+        />
+      );
+    }
+    if (blockId === "topRepos") {
+      return <TopReposBlock reposToShow={reposToShow} />;
    }
-    return renderTopReposBlock();
+    return null;
Evidence
BusinessCard’s dispatcher handles only five IDs and returns null otherwise, while the shared
CardBlockId/DEFAULT_CARD_LAYOUT include additional visible IDs (especially in the full column).
Layout normalization also appends missing default blocks back into the layout, so these unhandled
IDs can appear in the effective layout and thus render no content.

src/components/BusinessCard.tsx[16-57]
src/components/BusinessCard.tsx[58-90]
src/lib/types.ts[106-160]
src/lib/cardLayout.ts[16-69]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`BusinessCard.renderBlock` only renders 5 block IDs and returns `null` for all others, but `CardBlockId`/`DEFAULT_CARD_LAYOUT` include additional visible blocks. This causes those blocks to render empty content (and still get wrapped by layout containers), which can remove intended sections from the card.

### Issue Context
- `CardBlockId` includes many IDs beyond the 5 handled by `BusinessCard`.
- `DEFAULT_CARD_LAYOUT` marks several of those extra IDs as `visible: true` in the `full` column.
- `normalizeCardLayout` appends any missing default blocks back into saved layouts, so these IDs can appear even when users configured a smaller layout.

### Fix Focus Areas
- src/components/BusinessCard.tsx[16-90]
- src/lib/types.ts[106-160]
- src/lib/cardLayout.ts[16-69]

### What to change
Implement one of the following (pick the one that matches product intent):
1) **Implement renderers for the missing block IDs** (profile/contributions/heatmap/interests/skills/repos), potentially by extracting/adding additional `business-card/*Block.tsx` components.

2) **Introduce a BusinessCard-specific layout + IDs**:
  - Create a `BUSINESS_CARD_LAYOUT` containing only `avatar|bio|stats|topLanguages|topRepos`.
  - Make `BusinessCard` default to that layout instead of `DEFAULT_CARD_LAYOUT`.
  - Ensure `loadCardSettings` / normalization for the business card uses the business-card defaults.

3) **At minimum, avoid rendering empty wrappers**:
  - Filter out unsupported blocks before mapping, or in the map do:
    - compute `const node = renderBlock(block.id)` and return `node ? <div ...>{node}</div> : null`.
  - (Still recommended) also ensure unsupported IDs cannot be present/visible in the active layout.

Remediation recommended

2. Relative imports in BusinessCard.tsx 📘 Rule violation ✧ Quality
Description
src/components/BusinessCard.tsx and src/components/business-card/BioBlock.tsx import modules
that live under src/ using relative paths (e.g., ./business-card/AvatarBlock and ../Icons)
instead of the required @/ alias. This violates the repo’s standard import convention and can lead
to brittle paths during refactors.
Code

src/components/BusinessCard.tsx[R4-8]

+import { AvatarBlock } from "./business-card/AvatarBlock";
+import { BioBlock } from "./business-card/BioBlock";
+import { StatsBlock } from "./business-card/StatsBlock";
+import { TopLanguagesBlock } from "./business-card/TopLanguagesBlock";
+import { TopReposBlock } from "./business-card/TopReposBlock";
Evidence
Compliance ID 226103 requires that any import targeting code under src/ use the @/ path alias
rather than relative paths. In src/components/BusinessCard.tsx, the cited import lines use
./business-card/..., which resolves to modules under src/components/..., and in
src/components/business-card/BioBlock.tsx, the import ../Icons similarly resolves within
src/components, demonstrating noncompliant relative-path imports to src/ modules in both files.

Rule 226103: Use @/ path alias for src imports in frontend code

src/components/business-card/BioBlock.tsx[2-8]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Update imports in `src/components/BusinessCard.tsx` and `src/components/business-card/BioBlock.tsx` that reference modules under `src/` to use the required `@/` alias instead of relative paths.

## Issue Context
Compliance ID 226103 mandates `@/` alias usage for imports targeting code within `src/`. The current code uses relative paths such as `./business-card/...` (resolving under `src/components/...`) and `../Icons` from within `src/components/business-card/` (resolving under `src/components/`), which violates the convention and can become brittle during refactors.
