 ## Planned Enhancements
 
 ### 1. Automated Cluster Setup (High Priority)
-- [ ] Add GitHub Actions workflows with workflow_dispatch triggers
-- [ ] Implement automated terragrunt command execution for cluster building
+- [x] Add GitHub Actions workflows with workflow_dispatch triggers
+- [x] Implement automated terragrunt command execution for cluster building
+  - [x] Support for plan/apply/destroy commands
+  - [x] Environment-specific execution
+  - [x] Automated testing framework
 - [ ] Configure workflows to run on specific runners for credential management
 - [ ] Create templatized GitHub Actions workflow files
 - [ ] Enable direct cluster creation without manual repository cloning
