name: lint description: Run all linters and formatters — dotnet format, ESLint, helm lint, and terraform validate. Use to verify formatting before a PR. Note that hooks auto-fix on save/commit; this skill is for explicit verification across the full codebase. allowed-tools: Bash user-invocable: true

Lint

Run all project linters and report violations. Optionally fix auto-fixable issues.

Arguments

• --fix or fix — Apply auto-fixes (default: report only)
• backend — Only lint C# code
• frontend — Only lint frontend code
• helm — Only lint Helm charts
• terraform — Only lint Terraform/Terragrunt code

If no argument is given, lint everything in report-only mode.

Backend (.NET)

Check formatting violations (report only):

dotnet format src/SignalBeam.sln --verify-no-changes --verbosity normal

Fix formatting violations:

dotnet format src/SignalBeam.sln --verbosity normal

Frontend (React/TypeScript)

Check lint violations (report only):

cd web && npm run lint

Fix auto-fixable violations:

cd web && npm run lint:fix

Check TypeScript types:

cd web && npm run type-check

Helm Charts

Lint all charts in deploy/charts/:

helm lint deploy/charts/signalbeam-infrastructure
helm lint deploy/charts/signalbeam-platform

If additional charts exist under deploy/charts/, lint those too. Use ls deploy/charts/ to discover all charts.

Template render check (catches template errors without deploying):

helm template test deploy/charts/signalbeam-infrastructure > /dev/null
helm template test deploy/charts/signalbeam-platform > /dev/null

Terraform / Terragrunt

Validate Terraform modules:

# Find all Terraform module directories and validate each
for dir in $(find infra -name "*.tf" -exec dirname {} \; | sort -u); do
  echo "=== Validating $dir ==="
  terraform -chdir="$dir" init -backend=false -input=false 2>/dev/null
  terraform -chdir="$dir" validate
done

Format check (report only):

terraform fmt -check -recursive infra

Format fix:

terraform fmt -recursive infra

Terragrunt validate (if terragrunt.hcl files exist):

find infra -name "terragrunt.hcl" -execdir terragrunt validate \;

After Running

• Report the total violation count for each tool separately.
• For failures, show file path, line number (where available), and rule name.
• If running with --fix, report how many issues were auto-fixed and how many remain.
• If TypeScript type errors exist, list them separately from lint errors.
• Summarize with a pass/fail status per category:
  • .NET Format: PASS/FAIL
  • ESLint: PASS/FAIL
  • TypeScript: PASS/FAIL
  • Helm Lint: PASS/FAIL
  • Terraform Validate: PASS/FAIL
  • Terraform Format: PASS/FAIL
