VS Code extension for inspecting Helm values across environments. Hover, go-to-definition, and completion for .Values references; template definition hover and go-to-definition for include calls. Orphan diagnostics for unresolved refs and unused keys.
Features
Values hover: Hover over .Values.x.y.z in templates/**/*.{yaml,yml,tpl} → inline table of resolved values across all environments. Works in {{ .Values.x }}, {{ coalesce .Values.a .Values.b "default" }}, {{ or .Values.a .Values.b }}, {{ default "x" .Values.foo }}, {{ .Values.foo | default .Values.bar }}, {{ ternary .Values.a .Values.b .Values.flag }}, etc. Values that differ from the base are bold; missing keys show ⚠ not set.
Go to definition: Ctrl+click (or F12) on .Values.x.y.z → jumps to the key in values files. Ctrl+click on {{ include "template.name" . }} → jumps to the define block.
Completion: Type . after .Values or inside include " → suggests value paths and template names.
Template definition hover: Hover over {{ include "template.name" . }} → shows the define block source (file + full definition).
Orphan diagnostics: Squiggly lines for .Values paths not defined in any values file (Error); hint for value keys not referenced in templates (Hint). Right-click any orphan diagnostic → Add 'prefix' to orphan exclude list to add to helmValues.excludeOrphanPrefixes (e.g. secrets for .Values.secrets.*). Values passed to dependency charts are considered used if the subchart's templates reference them. When Chart.yaml lists dependencies not found in charts/, an informational diagnostic appears with a Quick Fix to run helm dependency update. Command palette: Helm: Refresh Diagnostics, Helm: Update Dependencies.
Supported layouts
Helmfile: helmfile.yaml at workspace root with explicit environments. Value layers: chart base → env values → secrets → system.
Override-folder: helm/*/values.yaml + helm/*/overrides/*.yaml. Environments inferred from override filenames.
Standalone: Plain chart with values.yaml only. Single "default" environment.
Custom: Set helmValues.environments and helmValues.valuesFilePattern to use explicit env list and a pattern like values/values-{env}.yml. Base path via helmValues.valuesBasePath. Takes precedence over helmfile/override-folder when both are set.

Description
helmValues.helmfilePath
Path to helmfile.yaml (default: helmfile.yaml)
helmValues.chartPath
Override chart path when multiple charts exist (e.g. nolo or helm/sample-gitops-2)
helmValues.baseValuesFile
Base values filename relative to chart root (default: values.yaml)
helmValues.overridesDir
Overrides directory relative to chart root (override-folder layout, default: overrides)
helmValues.secretsFilePath
Override for git-ignored secrets file
helmValues.environments
Explicit env list. With valuesFilePattern, enables custom layout
helmValues.valuesBasePath
Base path for value files (default: .). Used with custom layout
helmValues.valuesFilePattern
Pattern with {env} placeholder (e.g. values/values-{env}.yml)
helmValues.excludeOrphanPrefixes
Path prefixes to exclude. Use * for one segment (e.g. secrets.*). Examples: ["global.images","secrets"]
