npm run test:ps
```

## Usage

All scripts are designed to run both locally and in GitHub Actions workflows. They support common parameters like `-Verbose` and `-Debug` for troubleshooting.

### Local Testing

```powershell
# Test PSScriptAnalyzer on changed files
./scripts/linting/Invoke-PSScriptAnalyzer.ps1 -ChangedFilesOnly -Verbose

# Validate markdown frontmatter
./scripts/linting/Validate-MarkdownFrontmatter.ps1 -Verbose

# Check for language paths in URLs
./scripts/linting/Invoke-LinkLanguageCheck.ps1 -Verbose
```

### GitHub Actions Integration

All scripts automatically detect GitHub Actions environment and provide appropriate output formatting (annotations, summaries, artifacts).

## Contributing

When adding new scripts:

1. Follow PowerShell best practices (PSScriptAnalyzer compliant)
2. Include the entry point guard pattern (see below)
3. Support `-Verbose` and `-Debug` parameters
4. Add GitHub Actions integration using `LintingHelpers` module functions
5. Include inline help with `.SYNOPSIS`, `.DESCRIPTION`, `.PARAMETER`, and `.EXAMPLE`
6. Document in relevant README files
7. Test locally before creating PR

### Entry Point Guard Pattern

All production scripts use a dot-source guard that enables Pester tests to import functions without executing main logic. Extract main logic into an `Invoke-*` orchestrator function and wrap direct execution in a guard block:

```powershell
#region Functions

function Invoke-ScriptMain {
    [CmdletBinding()]
    param( <# script params #> )
    # Main logic here
}

#endregion Functions

#region Main Execution
if ($MyInvocation.InvocationName -ne '.') {
    try {
        Invoke-ScriptMain @PSBoundParameters
        exit 0
    }
    catch {
        Write-Error -ErrorAction Continue "ScriptName failed: $($_.Exception.Message)"
        Write-CIAnnotation -Message $_.Exception.Message -Level Error
        exit 1
    }
}
#endregion Main Execution
```

Key rules:

* The `if` guard wraps `try`/`catch` (not the reverse)
* Name the orchestrator `Invoke-*` matching the script noun
* Use `#region Functions` and `#region Main Execution` markers
* See [Package-Extension.ps1](extension/Package-Extension.ps1) for a canonical example
