Code Review — PR #321

Summary

This PR adds a new SEO article (multi-agent-workflow-patterns.mdx) and 7 SVG diagrams. The content itself is well-written, but the article will not appear in the blog due to metadata format and missing required fields.

---

Critical Issues

1. Wrong metadata format — article won't load

The article uses YAML frontmatter (--- blocks), but the blog system loads metadata via:

// src/web/src/lib/blog/posts/import-mdx.ts
const mod = await import(`@/content/${slug}.mdx`);
return mod.metadata;

Without remark-frontmatter + remark-mdx-frontmatter plugins (not configured in next.config.ts), YAML frontmatter is NOT exported as mod.metadata. The working articles in this repo use:

export const metadata = { slug: '...', title: '...', ... };

See why-we-built-alook.mdx, ai-agent-team.mdx, personal-ai-company.mdx for the correct format.

Fix: Replace the YAML frontmatter with export const metadata = { ... };

2. Missing required fields — validateMetadata will skip the post

BlogPost type (src/web/src/lib/blog/types.ts) requires: slug, title, date, author, excerpt, readingTime.

The article is missing:

• excerpt (has description instead — wrong field name)
• readingTime

Even if the metadata format were fixed, validateMetadata() would log a warning and skip the article.

---

Minor Issues

3. No newline at end of files — all 8 added files are missing trailing newlines (\ No newline at end of file).

4. Inconsistent asset path convention — existing blog images use subdirectories (/blog/ai-agent-team/hero.png), but these SVGs are flat in /blog/ (/blog/workflow-1-dev-team-pipeline.svg). Not a bug but breaks the pattern.

5. Extra fields unused — keywords, canonical, image in frontmatter aren't part of the BlogPost type. If you want SEO meta tags, that's a separate feature — these fields currently go nowhere.

---

Checklist

• Functionality: Article will NOT appear — metadata is unparseable
• Code Quality: Content is well-structured and readable
• Security: SVGs are clean (no scripts/event handlers)
• Tests: Should verify the article loads in the blog index after fixing metadata
• Project Syncing: Asset directory convention not followed
