Contributing a New Skill

To kickstart a new skill for this repo:

1. Initialize: Create a new skill from the template

   ./scripts/init_skill.sh my-skill-name appsec
   

2. Develop: Fill in SKILL.md and add bundled resources

   • scripts/ - Executable security tools
   • references/ - Security framework documentation
   • assets/ - Templates and configurations

3. Validate: Run the validation script

   ./scripts/validate_skill.py skills/appsec/my-skill-name
   

4. Update Documentation:

   • Add your skill to the README.md (this file) under the appropriate category
   • Update .claude-plugin/marketplace.json with your skill path

5. Submit: Open a PR with the [skill] tag

See CONTRIBUTE.md for detailed guidelines including the exact format for README.md entries.
