# Helm Version Upgrade Skill ## Purpose Manages Helm chart version upgrades across Terraform+Helm platforms. Handles an **atomic multi-file update** pattern: the Terraform file containing Helm module blocks + each module's variable file + any version-tracking documentation. ## Activation This skill activates when the user requests: - Checking for outdated Helm charts - Upgrading a specific Helm chart version - Upgrading all Helm charts - Checking version consistency across module files ## Step 0: Discover Repository Layout **Do NOT assume any hardcoded file names or paths.** Discover the repo structure at runtime: ### 0a: Find the Helm Module Orchestrator File Search for Terraform files containing Helm module blocks: ```bash grep -rl 'source\s*=.*modules.*helm\|module.*helm\|helm_release' --include="*.tf" . | grep -v '.terraform/' ``` This identifies the orchestrator file(s) (e.g., `3-gke-package.tf`, `main.tf`, `helm.tf`, etc.). ### 0b: Discover Module Directories Parse the orchestrator file(s) for `module` blocks. Extract `source` paths to find module directories: - Pattern: `source = "./modules/helm/<name>"` or `source = "../modules/<name>"` or any relative path - Verify each discovered directory exists ### 0c: Discover Module Variable Files For each module directory, find the variable file: - Check for `variable.tf` (singular), `variables.tf` (plural), or any `.tf` file containing `variable "install_version"` blocks - Pattern: `grep -l 'variable.*install_version\
