npm run sync-marketplaceautomatically - Validates with
jqandpython3 scripts/check-frontmatter.py - Follows same standards as CI/CD
Skills run the same checks as GitHub Actions:
.github/workflows/validate-plugins.ymlchecks- Security scans match CI patterns
- Validation matches CI requirements
- Fix issues before CI fails
- Claude Code CLI with Skills support (October 2025+)
- Working in
claude-code-pluginsrepository - Node.js for
npm run sync-marketplace - Python 3 for frontmatter validation
jqfor JSON validation
Say: "Create a security plugin, validate it, and add to marketplace" → All 3 skills activate automatically in sequence
Say: "Is everything ready to commit?" → Validator runs comprehensive check
Say: "Full audit for featured plugin status" → Auditor runs with higher quality thresholds
Say: "Bump to minor and update marketplace" → Version Bumper + Marketplace Manager work together
