Add Cloud Infrastructure Expert custom agent

[Copilot]

Implements a specialized custom agent for delegating cloud infrastructure, containerization, and deployment tasks within GitHub Copilot.

Changes

New Custom Agent Infrastructure

• .github/agents/cloud.agent.md - Cloud Infrastructure Expert agent with:

  • 7 tools (search, fetch, githubRepo, bash, view, edit, create)
  • Expertise in Docker containerization, Kubernetes orchestration, cloud platforms (AWS/Azure/GCP), and CI/CD
  • Handoff workflows to default agent for code review and implementation
  • References to 1,595 lines of existing instruction files for Docker, Kubernetes, and GitHub Actions best practices

• .github/agents/README.md - Documentation covering:

  • Usage guide for selecting and delegating to custom agents
  • Agent creation guidelines
  • Example queries and workflows

Usage

Users can now delegate infrastructure tasks by selecting "Cloud Infrastructure Expert" from the agents dropdown in VS Code Copilot Chat:

@cloud-infrastructure-expert Create a production-ready Kubernetes deployment 
for a Node.js API with health checks, resource limits, and autoscaling

The agent provides expertise in:

• Multi-stage Docker builds with security hardening
• Kubernetes manifests (Deployments, Services, Ingress, ConfigMaps, Secrets)
• Cloud infrastructure design (AWS ECS/EKS, Azure AKS, GCP GKE)
• GitHub Actions CI/CD pipelines for container deployment

Integration

Agent references existing best practices:

• _instructions/containerization-docker-best-practices.instructions.md (681 lines)
• _instructions/kubernetes-deployment-best-practices.instructions.md (307 lines)
• .github/instructions/github-actions-ci-cd-best-practices.instructions.md (607 lines)

Original prompt

Delegate: "Delegate to cloud agent"
