+# Merge Conflict Checker
+
+This composite GitHub Action checks for Git merge conflict markers in files changed in pull requests.
+
+## Purpose
+
+Automatically detects leftover merge conflict markers (`<<<<<<<`, `=======`, `>>>>>>>`) in pull request files to prevent them from being merged into the codebase.
+
+## Usage
+
+### In a Workflow
+
+```yaml
+- name: Check for merge conflict markers
+  uses: "./.github/actions/infrastructure/merge-conflict-checker"
+```
+
+### Complete Example
+
+```yaml
+jobs:
+  merge_conflict_check:
+    name: Check for Merge Conflict Markers
+    runs-on: ubuntu-latest
+    if: github.event_name == 'pull_request'
+    permissions:
+      pull-requests: read
+      contents: read
+    steps:
+      - name: checkout
+        uses: actions/checkout@v5
+
+      - name: Check for merge conflict markers
+        uses: "./.github/actions/infrastructure/merge-conflict-checker"
+```
+
+## How It Works
+
+1. **File Detection**: Uses GitHub's API to get the list of files changed in the pull request
+2. **Marker Scanning**: Reads each changed file and searches for the following markers:
+   - `<<<<<<<` (conflict start marker)
+   - `=======` (conflict separator)
+   - `>>>>>>>` (conflict end marker)
+3. **Result Reporting**: 
+   - If markers are found, the action fails and lists all affected files
+   - If no markers are found, the action succeeds
+
+## Outputs
+
+- `files-checked`: Number of files that were checked
+- `conflicts-found`: Number of files containing merge conflict markers
+
+## Behavior
+
+- **Event Support**: Only works with `pull_request` events
+- **File Handling**:
+  - Checks only files that were added, modified, or renamed
+  - Skips deleted files
+  - Skips binary/unreadable files
+  - Skips directories
+
+## Example Output
+
+When conflict markers are detected:
+
+```
+❌ Merge conflict markers detected in the following files:
+  - src/example.cs
+    Markers found: <<<<<<<, =======, >>>>>>>
+  - README.md
+    Markers found: <<<<<<<, =======, >>>>>>>
+
+Please resolve these conflicts before merging.
+```
+
+When no markers are found:
+
+```
+✅ No merge conflict markers found
+```
+
+## Integration
+
+This action is integrated into the `linux-ci.yml` workflow and runs automatically on all pull requests to ensure code quality before merging.

+# Guidelines for PowerShell Code Organization
+
+## When to Move Code from YAML to PowerShell Modules
+
+PowerShell code in GitHub Actions YAML files should be kept minimal. Move code to a module when:
+
+### Size Threshold
+- **More than ~30 lines** of PowerShell in a YAML file step
+- **Any use of .NET types** like `[regex]`, `[System.IO.Path]`, etc.
+- **Complex logic** requiring multiple nested loops or conditionals
+- **Reusable functionality** that might be needed elsewhere
+
+### Indicators to Move Code
+1. Using .NET type accelerators (`[regex]`, `[PSCustomObject]`, etc.)
+2. Complex string manipulation or parsing
+3. File system operations beyond basic reads/writes
+4. Logic that would benefit from unit testing
+5. Code that's difficult to read/maintain in YAML format
+
+## Which Module to Use
+
+### ci.psm1 (`tools/ci.psm1`)
+**Purpose**: CI/CD-specific operations and workflows
+
+**Use for**:
+- Build orchestration (invoking builds, tests, packaging)
+- CI environment setup and configuration
+- Test execution and result processing
+- Artifact handling and publishing
+- CI-specific validations and checks
+- Environment variable management for CI
+
+**Examples**:
+- `Invoke-CIBuild` - Orchestrates build process
+- `Invoke-CITest` - Runs Pester tests
+- `Test-MergeConflictMarker` - Validates files for conflicts
+- `Set-BuildVariable` - Manages CI variables
+
+**When NOT to use**:
+- Core build operations (use build.psm1)
+- Package creation logic (use packaging.psm1)
+- Platform-specific build steps
+
+### build.psm1 (`build.psm1`)
+**Purpose**: Core build operations and utilities
+
+**Use for**:
+- Compiling source code
+- Resource generation
+- Build configuration management
+- Core build utilities (New-PSOptions, Get-PSOutput, etc.)
+- Bootstrap operations
+- Cross-platform build helpers
+
+**Examples**:
+- `Start-PSBuild` - Main build function
+- `Start-PSBootstrap` - Bootstrap dependencies
+- `New-PSOptions` - Create build configuration
+- `Start-ResGen` - Generate resources
+
+**When NOT to use**:
+- CI workflow orchestration (use ci.psm1)
+- Package creation (use packaging.psm1)
+- Test execution
+
+### packaging.psm1 (`tools/packaging/packaging.psm1`)
+**Purpose**: Package creation and distribution
+
+**Use for**:
+- Creating distribution packages (MSI, RPM, DEB, etc.)
+- Package-specific metadata generation
+- Package signing operations
+- Platform-specific packaging logic
+
+**Examples**:
+- `Start-PSPackage` - Create packages
+- `New-MSIPackage` - Create Windows MSI
+- `New-DotnetSdkContainerFxdPackage` - Create container packages
+
+**When NOT to use**:
+- Building binaries (use build.psm1)
+- Running tests (use ci.psm1)
+- General utilities
+
+## Best Practices
+
+### Keep YAML Minimal
+```yaml
+# ❌ Bad - too much logic in YAML
+- name: Check files
+  shell: pwsh
+  run: |
+    $files = Get-ChildItem -Recurse
+    foreach ($file in $files) {
+      $content = Get-Content $file -Raw
+      if ($content -match $pattern) {
+        # ... complex processing ...
+      }
+    }
+
+# ✅ Good - call function from module
+- name: Check files
+  shell: pwsh
+  run: |
+    Import-Module ./tools/ci.psm1
+    Test-SomeCondition -Path ${{ github.workspace }}
+```
+
+### Document Functions
+Always include comment-based help for functions:
+```powershell
+function Test-MyFunction
+{
+    <#
+    .SYNOPSIS
+        Brief description
+    .DESCRIPTION
+        Detailed description
+    .PARAMETER ParameterName
+        Parameter description
+    .EXAMPLE
+        Test-MyFunction -ParameterName Value
+    #>
+    [CmdletBinding()]
+    param(
+        [Parameter(Mandatory)]
+        [string] $ParameterName
+    )
+    # Implementation
+}
+```
+
+### Error Handling
+Use proper error handling in modules:
+```powershell
+try {
+    # Operation
+}
+catch {
+    Write-Error "Detailed error message: $_"
+    throw
+}
+```
+
+### Verbose Output
+Use `Write-Verbose` for debugging information:
+```powershell
+Write-Verbose "Processing file: $filePath"
+```
+
+## Module Dependencies
+
+- **ci.psm1** imports both `build.psm1` and `packaging.psm1`
+- **build.psm1** is standalone (minimal dependencies)
+- **packaging.psm1** imports `build.psm1`
+
+When adding new functions, consider these import relationships to avoid circular dependencies.
+
+## Testing Modules
+
+Functions in modules should be testable:
+```powershell
+# Test locally
+Import-Module ./tools/ci.psm1 -Force
+Test-MyFunction -Parameter Value
+
+# Can be unit tested with Pester
+Describe "Test-MyFunction" {
+    It "Should return expected result" {
+        # Test implementation
+    }
+}
+```
+
+## Migration Checklist
+
+When moving code from YAML to a module:
+
+1. ✅ Determine which module is appropriate (ci, build, or packaging)
+2. ✅ Create function with proper parameter validation
+3. ✅ Add comment-based help documentation
+4. ✅ Use `[CmdletBinding()]` for advanced function features
+5. ✅ Include error handling
+6. ✅ Add verbose output for debugging
+7. ✅ Test the function independently
+8. ✅ Update YAML to call the new function
+9. ✅ Verify the workflow still works end-to-end

+# PowerShell Automatic Variables - Naming Guidelines
+
+## Purpose
+
+This instruction provides guidelines for avoiding conflicts with PowerShell's automatic variables when writing PowerShell scripts and modules.
+
+## What Are Automatic Variables?
+
+PowerShell has built-in automatic variables that are created and maintained by PowerShell itself. Assigning values to these variables can cause unexpected behavior and side effects.
+
+## Common Automatic Variables to Avoid
+
+### Critical Variables (Never Use)
+
+- **`$matches`** - Contains the results of regular expression matches. Overwriting this can break regex operations.
+- **`$_`** - Represents the current object in the pipeline. Only use within pipeline blocks.
+- **`$PSItem`** - Alias for `$_`. Same rules apply.
+- **`$args`** - Contains an array of undeclared parameters. Don't use as a regular variable.
+- **`$input`** - Contains an enumerator of all input passed to a function. Don't reassign.
+- **`$LastExitCode`** - Exit code of the last native command. Don't overwrite unless intentional.
+- **`$?`** - Success status of the last command. Don't use as a variable name.
+- **`$$`** - Last token in the last line received by the session. Don't use.
+- **`$^`** - First token in the last line received by the session. Don't use.
+
+### Context Variables (Use with Caution)
+
+- **`$Error`** - Array of error objects. Don't replace, but can modify (e.g., `$Error.Clear()`).
+- **`$PSBoundParameters`** - Parameters passed to the current function. Read-only.
+- **`$MyInvocation`** - Information about the current command. Read-only.
+- **`$PSCmdlet`** - Cmdlet object for advanced functions. Read-only.
+
+### Other Common Automatic Variables
+
+- `$true`, `$false`, `$null` - Boolean and null constants
+- `$HOME`, `$PSHome`, `$PWD` - Path-related variables
+- `$PID` - Process ID of the current PowerShell session
+- `$Host` - Host application object
+- `$PSVersionTable` - PowerShell version information
+
+For a complete list, see: https://learn.microsoft.com/powershell/module/microsoft.powershell.core/about/about_automatic_variables
+
+## Best Practices
+
+### ❌ Bad - Using Automatic Variable Names
+
+```powershell
+# Bad: $matches is an automatic variable used for regex capture groups
+$matches = Select-String -Path $file -Pattern $pattern
+
+# Bad: $args is an automatic variable for undeclared parameters
+$args = Get-ChildItem
+
+# Bad: $input is an automatic variable for pipeline input
+$input = Read-Host "Enter value"
+```
+
+### ✅ Good - Using Descriptive Alternative Names
+
+```powershell
+# Good: Use descriptive names that avoid conflicts
+$matchedLines = Select-String -Path $file -Pattern $pattern
+
+# Good: Use specific names for arguments
+$arguments = Get-ChildItem
+
+# Good: Use specific names for user input
+$userInput = Read-Host "Enter value"
+```
+
+## Naming Alternatives
+
+When you encounter a situation where you might use an automatic variable name, use these alternatives:
+
+| Avoid | Use Instead |
+|-------|-------------|
+| `$matches` | `$matchedLines`, `$matchResults`, `$regexMatches` |
+| `$args` | `$arguments`, `$parameters`, `$commandArgs` |
+| `$input` | `$userInput`, `$inputValue`, `$inputData` |
+| `$_` (outside pipeline) | Use a named parameter or explicit variable |
+| `$Error` (reassignment) | Don't reassign; use `$Error.Clear()` if needed |
+
+## How to Check
+
+### PSScriptAnalyzer Rule
+
+PSScriptAnalyzer has a built-in rule that detects assignments to automatic variables:
+
+```powershell
+# This will trigger PSAvoidAssignmentToAutomaticVariable
+$matches = Get-Something
+```
+
+**Rule ID**: PSAvoidAssignmentToAutomaticVariable
+
+### Manual Review
+
+When writing PowerShell code, always:
+1. Avoid variable names that match PowerShell keywords or automatic variables
+2. Use descriptive, specific names that clearly indicate the variable's purpose
+3. Run PSScriptAnalyzer on your code before committing
+4. Review code for variable naming during PR reviews
+
+## Examples from the Codebase
+
+### Example 1: Regex Matching
+
+```powershell
+# ❌ Bad - Overwrites automatic $matches variable
+$matches = [regex]::Matches($content, $pattern)
+
+# ✅ Good - Uses descriptive name
+$regexMatches = [regex]::Matches($content, $pattern)
+```
+
+### Example 2: Select-String Results
+
+```powershell
+# ❌ Bad - Conflicts with automatic $matches
+$matches = Select-String -Path $file -Pattern $pattern
+
+# ✅ Good - Clear and specific
+$matchedLines = Select-String -Path $file -Pattern $pattern
+```
+
+### Example 3: Collecting Arguments
+
+```powershell
+# ❌ Bad - Conflicts with automatic $args
+function Process-Items {
+    $args = $MyItems
+    # ... process items
+}
+
+# ✅ Good - Descriptive parameter name
+function Process-Items {
+    [CmdletBinding()]
+    param(
+        [Parameter(ValueFromRemainingArguments)]
+        [string[]]$Items
+    )
+    # ... process items
+}
+```

+## Summary
+
+**Key Takeaway**: Always use descriptive, specific variable names that clearly indicate their purpose and avoid conflicts with PowerShell's automatic variables. When in doubt, choose a longer, more descriptive name over a short one that might conflict.
