Review Summary

Hey @Andiveli! Thanks for the NestJS skill - the content looks solid. However, there are some issues that need fixing:

1. Wrong Directory (Security Check will fail)

You're adding to curated/nestjs/SKILL.md but community contributions must go in the community/ folder:

❌ curated/nestjs/SKILL.md      # Maintainers only
✅ community/nestjs/SKILL.md    # Community contributions

2. PR Title Format

For community skills, please use this title format:

❌ feat(nestjs): add NestJS enterprise patterns skill
✅ [Community Skill] NestJS Enterprise Patterns

3. Missing Labels

The community-skill and voting labels weren't added because:

1. Wrong directory (not in community/)
2. Wrong title format (no [Community Skill] prefix)

How to Fix

1. Move your file: community/nestjs/SKILL.md
2. Update PR title to: [Community Skill] NestJS Enterprise Patterns
3. Push the changes

What's Good

• Great content structure
• Proper conventional commit
• Excellent code examples and anti-patterns

Looking forward to the updated PR!

Hey @Andiveli, this looks really solid 👏

The PR is failing due to repository rules (not the content). To fix it:

1. Update the PR title:
   [Community Skill] NestJS Enterprise Patterns

2. Move the file to the correct path:
   community/nestjs/SKILL.md

   (Currently it's in curated/, which is restricted to maintainers only.)

After these changes, the CI checks should pass and the PR will enter the voting process 👍
