Corrections Applied

Frontmatter Fixes

1. Name Corrections:

   • vercel-deploy-claimable: Fixed name from "vercel-deploy" to "vercel-deploy-claimable"
   • using-neon: Fixed name from "neon-postgres" to "using-neon"

2. Metadata Cleanup:

   • Removed unnecessary metadata, author, version fields where present
   • Standardized to required fields: name, description, source, risk
   • Added missing risk: safe to all skills

Content Improvements

1. Added "When to Use" Sections:

   • All 24 skills now have proper "## When to Use" sections
   • Sections include clear trigger scenarios
   • Based on skill descriptions and functionality

2. Content Quality:

   • Removed all HTML document structure (DOCTYPE, html, head, body tags)
   • Removed GitHub navigation elements
   • Removed GitHub asset links (CSS, JS)
   • Preserved actual skill content and instructions

Validation Results

All 24 converted skills pass strict validation:

• ✅ Valid frontmatter with required fields
• ✅ "When to Use" section present

Technical Details

HTML Detection

Skills were identified as having HTML content if they contained:

• <!DOCTYPE html> declarations
• <html> tags
• GitHub asset links (github.githubassets.com)
• GitHub navigation elements

Conversion Process

1. Parse frontmatter - Extract and preserve metadata
2. Build raw URL - Convert GitHub tree/blob URLs to raw URLs
3. Download raw - Attempt to download markdown file
4. Extract from HTML - If raw unavailable, extract from HTML structure
5. Create minimal - If extraction fails, create from description
6. Validate - Ensure compliance with quality standards

URL Conversion Patterns

• github.com/org/repo/tree/main/path → raw.githubusercontent.com/org/repo/main/path/SKILL.md
• github.com/org/repo/blob/main/path/SKILL.md → raw.githubusercontent.com/org/repo/main/path/SKILL.md

Issues Resolved
