Findings

• [Major] Placeholder aggregateRating JSON-LD can be treated as misleading structured data and hurt search visibility. The PR adds a synthetic 5-star rating with one review while also marking it as placeholder, which should not be published metadata, evidence website/.vitepress/config.ts:87.
  Suggested fix:

  // Remove placeholder rating block until real review data exists
  // aggregateRating: {
  //   '@type': 'AggregateRating',
  //   ratingValue: '5',
  //   reviewCount: '1',
  // },

• [Minor] README contains an unresolved demo URL (watch?v=TODO), which creates a broken CTA in public docs, evidence README.md:30.
  Suggested fix:

  <!-- until demo video exists -->
  <!-- ▶ [Watch on YouTube](https://www.youtube.com/watch?v=TODO) -->

• [Minor] Chinese README has the same unresolved watch?v=TODO demo URL, evidence README.zh-CN.md:30.
  Suggested fix:

  <!-- 在真实视频发布前先移除占位链接 -->
  <!-- ▶ [在 YouTube 观看](https://www.youtube.com/watch?v=TODO) -->

Summary

• Review mode: initial
• 3 issues found on changed lines (1 Major, 2 Minor).
• Required context files docs/VISION.md and docs/PRINCIPLES.md: Not found in repo/docs.
• Hard-constraint checks in this diff: no direct provider SDK imports, no dependency/license/install-size changes detected.

Testing

• Not run (automation). Suggested coverage: add CI link-check (README + docs) and a VitePress build-time check for metadata placeholders.

Findings

• [Minor] Broken YouTube CTA in English README (watch?v=TODO) leads users to a non-existent target, evidence README.md:30.
  Suggested fix:

  <!-- Remove placeholder link until video is live -->
  <!-- ▶ [Watch on YouTube](https://www.youtube.com/watch?v=TODO) -->

• [Minor] Broken YouTube CTA in Chinese README (watch?v=TODO) has the same issue, evidence README.zh-CN.md:30.
  Suggested fix:

  <!-- 真实视频上线前先移除占位链接 -->
  <!-- ▶ [在 YouTube 观看](https://www.youtube.com/watch?v=TODO) -->

Summary

• Review mode: follow-up after new commits
• 2 issues found on changed lines (both Minor).
• Verified fixed from previous review: placeholder aggregateRating was removed from JSON-LD in website/.vitepress/config.ts.
• Required context files docs/VISION.md and docs/PRINCIPLES.md: Not found in repo/docs.
• Hard-constraint checks in this diff: no direct provider SDK imports, no dependency/license/install-size changes detected.

Testing

• Not run (automation). Suggested coverage: link-check for README/docs external CTAs.

Findings

• [Major] Global canonical points all pages to the site root canonical URL, which can cause search engines to treat /quickstart, /architecture, /roadmap, and localized pages as duplicates of home, reducing discoverability and potentially de-indexing those pages. Evidence website/.vitepress/config.ts:66.
  Suggested fix:

  // Remove the static canonical tag from `head`, then add a per-page canonical:
  transformHead: ({ pageData }) => {
    const path = pageData.relativePath
      .replace(/index\.md$/, '')
      .replace(/\.md$/, '');
  
    return [[
      'link',
      { rel: 'canonical', href: new URL(path, SITE_URL).toString() },
    ]];
  },

Summary

• Review mode: follow-up after new commits
• 1 issue found on changed lines.
• Required context docs docs/VISION.md and docs/PRINCIPLES.md: Not found in repo/docs.
• Hard-constraint checks in this diff: no direct provider SDK imports, no dependency/license/install-size changes detected, and DCO sign-off is present on commits.

Testing

• Not run (automation). Suggested coverage: build docs and verify canonical URL differs per route (home, /quickstart, /architecture, /zh/).

Findings

• [Major] README hero image paths point to a non-existent file, so the primary visual renders as a broken image on GitHub and docs previews. Evidence README.md:10, README.zh-CN.md:10.
  Suggested fix:

  <!-- Option A: point to an existing asset until hero.png is added -->
  <img src="website/public/og.svg" alt="Open CoDesign — prompt to prototype" width="900" />
  
  <!-- Option B: remove the img block until website/public/hero.png is committed -->

• [Minor] og:url is hardcoded to the site root, so non-home pages emit incorrect Open Graph canonical URL metadata. Evidence website/.vitepress/config.ts:42.
  Suggested fix:

  transformPageData(pageData) {
    const path = pageData.relativePath.replace(/index\.md$/, '').replace(/\.md$/, '');
    const canonical = `${SITE_URL}${path}`;
    pageData.frontmatter.head ??= [];
    pageData.frontmatter.head.push(['link', { rel: 'canonical', href: canonical }]);
    pageData.frontmatter.head.push(['meta', { property: 'og:url', content: canonical }]);
  },

Summary

• Review mode: follow-up after new commits
• 2 issues found on changed lines.
• Required context docs docs/VISION.md and docs/PRINCIPLES.md: Not found in repo/docs.
• Hard-constraint checks in this diff: no direct provider SDK imports, no dependency/license/install-size changes detected, and DCO sign-off is present on commits.

Testing

• Not run (automation). Suggested coverage: pnpm --filter website docs:build and inspect generated page head tags (canonical, og:url) for /, /quickstart, and /zh/quickstart.

Findings

• [Minor] og:url is still pinned to the site root, so shared links for non-home pages can publish incorrect URL metadata. Evidence website/.vitepress/config.ts:42 and canonical logic at website/.vitepress/config.ts:100-105.
  Suggested fix:

  transformPageData(pageData) {
    const path = pageData.relativePath.replace(/index\.md$/, '').replace(/\.md$/, '');
    const canonical = `${SITE_URL}${path}`;
    pageData.frontmatter.head ??= [];
    pageData.frontmatter.head.push(['link', { rel: 'canonical', href: canonical }]);
    pageData.frontmatter.head.push(['meta', { property: 'og:url', content: canonical }]);
  }
  
  // Remove the static root value from head:
  // ['meta', { property: 'og:url', content: SITE_URL }],

Summary

• Review mode: follow-up after new commits
• 1 issue found on changed lines.
• docs/VISION.md and docs/PRINCIPLES.md: Not found in repo/docs (as noted in CLAUDE.md, docs are gitignored/internal).
• Hard-constraint checks in this diff: no direct provider SDK imports, no dependency/license/install-size changes detected.

Testing

• Not run (automation). Suggested checks: build docs and inspect generated metadata for /, /quickstart, and /zh/quickstart to ensure og:url equals each page canonical URL.
