Implementation Process

Phase 1: Analysis ✅

Created scripts/analyze_voltagent_repo.py to:

• Fetch and parse the VoltAgent README.md
• Extract all skill references (format: **[org/skill-name](url)**)
• Normalize skill names to kebab-case
• Compare with existing skills in data/catalog.json

Result: Identified 53 new skills not present in the current collection.

Phase 2: Source Validation ✅

Created scripts/validate_voltagent_sources.py to:

• Verify GitHub URL accessibility
• Check for SKILL.md file presence
• Validate license compatibility
• Identify official vs community skills

Result:

• ✅ 49 skills validated successfully
• ❌ 4 skills failed (URL 404 errors)

Phase 3: Implementation ✅

Created scripts/implement_voltagent_skills.py to:

• Download SKILL.md files from GitHub repositories
• Ensure frontmatter compliance (name, description, source, risk)
• Add "When to Use" sections where missing
• Create minimal SKILL.md for skills without downloadable files

Result: All 49 validated skills successfully implemented.

Phase 4: Catalog Update ✅

• Updated data/skills_index.json: 609 skills total
• Updated data/catalog.json: 602 skills total
• Updated CATALOG.md: Regenerated catalog documentation
