name: content-layer description: "This skill should be used when the user asks to 'create an article', 'add a blog post', 'modify frontmatter', 'add a category', or 'update content schema'. Provides guidance for MDX articles, content-collections, and static content data in content/articles/.mdx, content/data/.ts, content-collections.ts."

Content Layer Skill

Scope

• content/articles/*.mdx - MDX article files
• content/data/*.ts - Static content data (categories, roles, projects, testimonials)
• content-collections.ts - Article schema configuration
• lib/content/articles.ts - Article fetching utilities

Decision Tree

Creating a new article?

1. Choose numeric prefix: Check existing articles in content/articles/ and use next sequential number (e.g., 0005-)
2. Create file: content/articles/[NNNN]-[slug].mdx
3. Add frontmatter with ALL required fields (see template below)
4. Use only valid categories from content/data/categories.ts
5. Add cover image to Cloudinary first, use public ID

Adding a new category?

1. Edit content/data/categories.ts: Add to CATEGORYTITLES array
2. Verify alphabetical sorting is maintained in code (array auto-sorts)
3. Update any affected articles if needed

Modifying article schema?

1. Read content-collections.ts first
2. Update Zod schema in schema function
3. Update transform if new computed fields needed
4. Run build to verify all articles pass validation

Quick Templates

Article Frontmatter (Required Fields)

Copy---
isPublished: false
title: "Article Title Here"
author: Suneet Misra
date: YYYY-MM-DD
updatedAt: YYYY-MM-DD
description: A brief description of the article (used in meta tags and previews)
coverImage: cloudinary-public-id_suffix
keywords: ["keyword1", "keyword2", "keyword3"]
categories: ["node", "typescript"]
---

Article with Series Section

Copy---
# ... frontmatter ...
---

<SuspendedArticleImage
  src="cloudinary-public-id"
  alt="descriptive alt text"
/>

<SeriesSection
  seriesDescription="This article is part of a series..."
  seriesEntries={[
    { id: 1, title: "Part 1", slug: "article-slug-1", isCurrent: true },
    { id: 2, title: "Part 2", slug: "article-slug-2" },
  ]}
/>

## Content starts here...

New Category Entry

Copy// In content/data/categories.ts
export const CATEGORYTITLES = [
  // ... existing categories (alphabetically sorted in output)
  "new-category",
] as const;

Mistakes

• ❌ z.string().uuid() - articles don't have UUIDs
• ❌ Missing required frontmatter fields (build will fail)
• ❌ Categories not in CATEGORYTITLES array
• ❌ Skipping numeric prefix in filename (breaks slug generation)
• ❌ isPublished: true before article is ready
• ❌ Wrong date format (must be YYYY-MM-DD)

Validation

After changes, run:

Copy.claude/skills/content-layer/scripts/validate-content-patterns.sh <file>
pnpm build  # Full validation of all content

File Naming Convention

Articles: [NNNN]-[descriptive-slug].mdx

• NNNN: 4-digit zero-padded number (0001, 0002, etc.)
• descriptive-slug: kebab-case title slug
• Example: 0005-building-a-nextjs-blog.mdx
