What this skill does

# Harness Code Integration Skill

Manage Harness Code repositories, triggers, PR pipelines, and GitOps workflows.

## Use For
- Repository setup, branch protection, PR validation pipelines
- Triggers (push, PR, tag), GitOps workflows, code policies

## Repository Structure for EKS Deployments

```
