Proposed Changes

This PR makes the option to install the Studio CLI more easily available by exposing a toggle in the settings modal:

Screenshot 2025-11-07 at 15 29 31

From a technical perspective, this PR does the following:

  • Implements the new UI
  • Adds RTK Query hooks for querying whether the CLI is installed
  • Adds RTK Query mutations for installing and uninstalling the CLI
  • Adds a procedure for uninstalling the CLI on macOS and Windows (we didn't have this previously)
  • On Windows, we no longer automatically install the CLI when the app launches
  • Tweaks the script that executes Studio CLI to also support running in development node (using the system level node executable and a different location for the CLI JS bundle)

Testing Instructions

  1. Open the settings modal
  2. Ensure that the Save button is only enabled when you've changed the value of any of the settings
  3. Change the install toggle for Studio CLI
  4. Save the settings
  5. Open your terminal and ensure that the studio command is available of unavailable (depending on which action you just took)
  6. Open the settings modal again and flip the toggle back
  7. Open your terminal and ensure that the studio command is available of unavailable (depending on which action you just took)

Code Review Complete ✅

I've completed a comprehensive code review of this PR focusing on cross-platform compatibility, code quality, security, performance, and testing.

Summary

This PR successfully adds a user-facing toggle in the Settings modal to install/uninstall the Studio CLI on macOS and Windows. The implementation is generally well-structured, but I've identified several issues that should be addressed before merging.

Critical Issues 🔴

1. Bug: Incorrect Uninstall Success Message (darwin.ts:70-71)

The uninstall confirmation dialog displays "CLI Installed" and "The CLI has been installed successfully" instead of the uninstall messages. This is a copy-paste error that will confuse users.

2. Missing Sentry Error Tracking (darwin.ts:91)

The uninstallCliWithConfirmation function doesn't capture exceptions to Sentry like the install function does, leading to inconsistent error tracking.

High Priority Issues 🟡

3. Error Handling: Windows Uninstall (win32.ts:116)

The Windows uninstallCli function has no error handling. Registry operations can fail, and errors will propagate uncaught. This could leave the system in an inconsistent state.

4. Error Handling: Installation Status Check (win32.ts:97)

When checking if CLI is installed fails (e.g., registry permission errors), the function returns false and logs the error. This masks actual errors as "not installed" rather than "error checking status".

5. UX: Missing Windows User Information (studio-cli-toggle.tsx:32)

Only macOS users see explanatory text about admin privileges. Windows users should also be informed that registry PATH modifications will occur.

Medium Priority Issues 🟠

6. Security: Shell Script Validation (uninstall-studio-cli.sh:14)

The uninstall script doesn't verify that the symlink actually points to Studio CLI before removing it. Consider adding validation to prevent accidental deletion of similarly-named symlinks.

7. Loading States Not Handled (preferences-tab.tsx:29)

The preferences tab doesn't handle loading states for the CLI installation status query. This could briefly show incorrect toggle state during initial load.

8. Code Documentation: Development Mode Behavior (win32.ts:127)

The installCli function returns early in development mode without explanation. This should be documented so developers understand why CLI installation doesn't work in dev mode.

Low Priority Issues / Suggestions 🔵

9. Code Comments: Linux Support (installation/index.ts:12)

Functions return false for Linux without explaining that CLI installation isn't yet supported on that platform.

10. Behavior Change Documentation (index.ts:338)

The removal of automatic Windows CLI installation is a significant behavior change. Consider adding a code comment explaining this decision.

11. Potential Race Condition (preferences-tab.tsx:50)

Multiple settings mutations fire in parallel without awaiting each other. This is likely fine for independent operations but worth noting.

Testing Coverage ✅

The test file has been updated to include the new CLI toggle:

  • Test properly mocks isStudioCliInstalled
  • "Studio CLI" label is verified to appear in preferences tab
  • Good coverage of tab navigation and IPC communication

Recommendation: Consider adding specific tests for:

  • CLI toggle interaction (clicking the toggle)
  • Loading states during installation/uninstallation
  • Error states when installation fails

Cross-Platform Compatibility ✅

The implementation properly separates platform-specific code:

  • ✅ macOS: Uses symlinks with sudo elevation
  • ✅ Windows: Uses registry PATH modification
  • ✅ Linux: Returns false (documented as unsupported)
  • ✅ Proper use of process.platform checks throughout

Security Assessment ✅

Generally good security practices:

  • ✅ IPC handlers properly exported and validated
  • ✅ Uses sudo-prompt library for privilege elevation
  • ✅ Registry operations use proper Windows APIs
  • ⚠️ Consider adding symlink target validation (issue Add fresh translations from Glotpress #6)

Performance Impact ✅

Minimal performance impact:

  • CLI installation queries are cached via RTK Query
  • Installation/uninstallation operations run async and don't block UI
  • No bundle size concerns

Architecture & Code Quality 🎯

Strengths:

  • Clean separation of concerns with platform-specific modules
  • Good use of RTK Query for state management
  • Proper IPC abstraction through preload script
  • Follows existing codebase patterns

Areas for Improvement:

  • Error handling consistency across platforms
  • Better user feedback during async operations
  • More comprehensive code comments

Recommendations

  1. Must Fix Before Merge:

  2. Should Fix:

  3. Nice to Have:

    • Add code comments for Linux support and dev mode behavior
    • Consider adding symlink validation in uninstall script
    • Add more comprehensive tests for toggle interactions

Testing Instructions

Please ensure the following manual testing is completed:

macOS:

  1. ✅ Toggle ON: Verify sudo prompt appears and symlink is created at /usr/local/bin/studio
  2. ✅ Verify studio command works in terminal
  3. ✅ Toggle OFF: Verify sudo prompt appears and symlink is removed
  4. ✅ Test with existing symlink that points elsewhere (should show error)
  5. ✅ Test when /usr/local/bin/studio is a regular file (should show error)

Windows:

  1. ✅ Toggle ON: Verify PATH is modified in registry
  2. ✅ Verify studio command works in Command Prompt and PowerShell
  3. ✅ Toggle OFF: Verify PATH entry is removed from registry
  4. ✅ Test with insufficient permissions (should handle gracefully)
  5. ✅ Verify proxy batch file is created in AppData

Both Platforms:

  1. ✅ Toggle state persists across app restarts
  2. ✅ Toggle state accurately reflects actual installation status
  3. ✅ Settings modal "Save" button only enables when changes are made
  4. ✅ Error messages are user-friendly and actionable

Overall, this is a solid implementation that brings much-needed user control over CLI installation. The critical bugs should be fixed before merging, but the architecture and approach are sound.

Code Review Complete

I've reviewed the PR that adds CLI installation/uninstallation functionality to the settings modal. Overall, this is a solid implementation with good separation of concerns. Here are my findings:


🟢 Strengths

  1. Good architecture - Clean separation between platform-specific installation logic (darwin.ts, win32.ts) and unified interface (index.ts)
  2. RTK Query integration - Proper use of queries and mutations with cache invalidation
  3. User feedback - Dialog confirmations for success/error cases
  4. Permission handling - Appropriate use of sudoExec for privileged operations on macOS
  5. Removes automatic installation - Good UX change to make CLI installation opt-in rather than automatic on Windows

🟡 Issues Found

1. Bug in uninstall confirmation dialog (darwin.ts:64-72)

The uninstallCliWithConfirmation function shows the wrong message on success:

// Line 70-71
title: __( 'CLI Installed' ),
message: __( 'The CLI has been installed successfully.' ),

Should be:

title: __( 'CLI Uninstalled' ),
message: __( 'The CLI has been uninstalled successfully.' ),

This is a copy-paste error from the installCliWithConfirmation function above it.


2. Logic issue in uninstall validation (darwin.ts:97-108)

The uninstall function checks if the symlink exists and is valid, but the logic is confusing:

try {
  const stats = await lstat( cliSymlinkPath );
  
  if ( ! stats.isSymbolicLink() ) {
    throw new Error( ERROR_FILE_ALREADY_EXISTS );
  }
} catch ( error ) {
  if ( isErrnoException( error ) && error.code === 'ENOENT' ) {
    // File does not exist, which means we can proceed with the installation.
  } else {
    throw error;
  }
}

The comment says "proceed with the installation" but this is in the uninstall function. If the file doesn't exist (ENOENT), the function should probably return early or notify the user that the CLI is already uninstalled, rather than silently continuing to try to unlink a non-existent file.


3. Inconsistent error handling (darwin.ts:34 vs darwin.ts:74-80)

  • installCliWithConfirmation captures errors to Sentry (line 34)
  • uninstallCliWithConfirmation does NOT capture errors to Sentry (line 74-88)

For consistency and debugging, uninstall errors should also be captured:

export async function uninstallCliWithConfirmation() {
  try {
    await uninstallCli();
    // ... success dialog
  } catch ( error ) {
    Sentry.captureException( error ); // ADD THIS
    let message: string = __(
      'There was an unknown error. Please check the logs for more information.'
    );
    // ... rest of error handling
  }
}

4. Missing Sentry capture in uninstallCli (win32.ts:116-124)

The uninstallCli function in win32.ts doesn't have any error handling or Sentry capture. If registry operations fail, errors will bubble up silently:

export async function uninstallCli() {
  try {
    const currentPath = await getPathFromRegistry();
    const newPath = currentPath
      .split( ';' )
      .filter( ( item ) => item.trim().toLowerCase() !== unversionedBinDirPath.toLowerCase() )
      .join( ';' );

    await setPathInRegistry( newPath );
  } catch ( error ) {
    Sentry.captureException( error ); // ADD THIS
    throw error;
  }
}

5. Platform check in installCli is inconsistent (win32.ts:127-133)

The installCli function has a development mode check that prevents installation:

if ( process.platform !== 'win32' || process.env.NODE_ENV === 'development' ) {
  return;
}

But uninstallCli has no such check. This creates an inconsistency where:

  • In development, users can uninstall but not install
  • If accidentally called on non-Windows platforms, uninstall will attempt to run

Both functions should have consistent platform guards:

export async function uninstallCli() {
  if ( process.platform !== 'win32' ) {
    return; // Or throw an error
  }
  // ... rest of function
}

6. Minor: Incomplete uninstall on Windows

The Windows uninstall only removes the PATH entry but doesn't delete the proxy batch file created at unversionedBinDirPath. This leaves orphaned files. Consider adding:

await unlink( path.join( unversionedBinDirPath, 'studio.bat' ) );

🔵 Suggestions

  1. Testing: The test mock (user-settings.test.tsx:30) returns a hardcoded true for isStudioCliInstalled. Consider testing both installed and uninstalled states.

  2. UI feedback: The mutation happens immediately when toggling. Consider showing a loading state on the toggle while the install/uninstall operation is in progress, since these operations can take time (especially with sudo prompts).

  3. Error messaging: On Windows, if registry operations fail, users get a generic error. Consider more specific error messages like "Failed to modify Windows registry" or "Permission denied".

  4. Batch file cleanup: The uninstall script on macOS (bin/uninstall-studio-cli.sh) is simple and clean. Consider a similar approach for Windows to clean up the proxy batch file.


📝 Architecture Documentation

The custom instructions asked me to check if docs/ai-instructions.md needs updates. After reviewing, no updates are needed because:

  • This PR doesn't change core architecture patterns
  • IPC handlers follow existing conventions
  • RTK Query usage is consistent with other endpoints
  • CLI installation is a feature addition, not an architectural change
  • No changes to WordPress providers, site server, or build configuration

✅ Summary

This is a well-structured PR that improves user experience by making CLI installation opt-in. The main issues are:

  1. Critical: Wrong dialog message in uninstall confirmation (darwin.ts:70-71)
  2. Important: Missing Sentry error capture in uninstall functions
  3. Important: Inconsistent platform/environment checks between install and uninstall
  4. Minor: Confusing comment and logic in uninstall validation
  5. Minor: Incomplete cleanup of batch file on Windows uninstall

Once these are addressed, this should be good to merge!

Documentation Updated Successfully

I've reviewed the IPC and API changes in this PR and updated the documentation accordingly.

Summary of Changes

The PR introduces three new IPC handlers for CLI installation management:

New IPC Handlers:

  • isStudioCliInstalled() - Check if Studio CLI is installed
  • installStudioCli() - Install the Studio CLI
  • uninstallStudioCli() - Uninstall the Studio CLI

New RTK Query Hooks:

  • useGetStudioCliIsInstalledQuery() - Query hook for CLI installation status
  • useSaveStudioCliIsInstalledMutation() - Mutation hook for install/uninstall operations

RTK Query Tag Improvements:

  • Split UserPreferences tag into separate UserEditor and UserTerminal tags for more granular cache invalidation
  • Added new StudioCliIsInstalled tag for CLI installation state

Documentation Updates

I've updated docs/ai-instructions.md with:

  1. New CLI installation API examples in the "IPC Communication Pattern" section (lines 150-153)
  2. Detailed installedAppsApi endpoint documentation in the "Redux Store Architecture" section (lines 180-187)
  3. Updated the last modified date to 2025-11-10

The changes follow the existing documentation patterns and provide clear guidance for developers working with the CLI installation features.

Security: Missing validation of symlink target

Before removing the symlink, consider verifying that it actually points to a Studio CLI location. This would prevent accidental deletion of symlinks that happen to have the same name but point elsewhere.

Additionally, consider checking if the path is actually a symlink before attempting to remove it to provide better error messages.

Code Quality: Guard condition prevents function from running in development

The condition process.env.NODE_ENV === 'development' causes the function to return early in development mode. This might be intentional, but it's worth documenting why this is the case. If developers need to test CLI installation in development, this will prevent it.

Consider adding a comment explaining the rationale:

// Skip CLI installation in development mode as it's not needed for testing
if ( process.platform !== 'win32' || process.env.NODE_ENV === 'development' ) {
	return;
}

Potential Race Condition: Async operations not awaited in sequence

All mutations are fired without awaiting the previous one, which could lead to race conditions if multiple settings are changed simultaneously. While this may work fine in practice, consider whether these should be executed sequentially to ensure proper order:

if ( dirtyLocale ) {
	await dispatch( saveUserLocale( dirtyLocale ) );
}
if ( dirtyEditor ) {
	await saveEditor( dirtyEditor );
}
if ( dirtyTerminal ) {
	await saveTerminal( dirtyTerminal );
}
if ( dirtyIsCliInstalled !== undefined ) {
	await saveCliIsInstalled( dirtyIsCliInstalled );
}

However, if these are independent operations, the current parallel execution is fine and more efficient.

Error Handling: Missing error handling for install/uninstall failures

The mutation doesn't handle errors that may occur during installation or uninstallation. If installStudioCli() or uninstallStudioCli() throw an error, it will propagate to the caller, but there's no specific error handling or user feedback here.

Consider adding try-catch to provide better error information:

saveStudioCliIsInstalled: builder.mutation< boolean, boolean >( {
	queryFn: async ( isInstalled ) => {
		try {
			if ( isInstalled ) {
				await getIpcApi().installStudioCli();
			} else {
				await getIpcApi().uninstallStudioCli();
			}
			return { data: isInstalled };
		} catch ( error ) {
			return { 
				error: { 
					status: 'CUSTOM_ERROR',
					error: error instanceof Error ? error.message : 'Unknown error'
				} 
			};
		}
	},
	invalidatesTags: [ 'StudioCliIsInstalled' ],
} ),

However, the current implementation may be intentional to let errors bubble up naturally.

Error Handling: No error handling for uninstallCli

The uninstallCli function doesn't have try-catch blocks or error handling. If registry operations fail, errors will propagate uncaught. Consider adding error handling similar to installPath():

export async function uninstallCli() {
	try {
		const currentPath = await getPathFromRegistry();
		const newPath = currentPath
			.split( ';' )
			.filter( ( item ) => item.trim().toLowerCase() !== unversionedBinDirPath.toLowerCase() )

Error Handling: isCliInstalled returns false on error

When an error occurs checking if CLI is installed, the function returns false and logs the error. This could mask actual errors (like registry permission issues) as "not installed". Consider differentiating between "not installed" and "error checking installation status":

export async function isCliInstalled(): Promise< boolean > {
	try {
		const currentPath = await getPathFromRegistry();

		if ( ! isStudioCliInPath( currentPath ) ) {
			return false;
		}

		if ( ! existsSync( unversionedBinDirPath ) ) {

		}

		return true;
	} catch ( error ) {

		Sentry.captureException( error );
		// Consider throwing or returning a sentinel value to indicate error state
		return false;

Code Quality: Consider loading states

The component uses data from queries but doesn't handle loading states. If isCliInstalled is undefined during the initial query, the default value false is used.

const { data: isCliInstalled, isLoading: isCliInstalledLoading } = useGetStudioCliIsInstalledQuery();

// Later in render:
<StudioCliToggle

Architecture Review Complete

I've reviewed the architectural changes in this PR and assessed the documentation updates.

Todo List:

  • Read current documentation state
  • Review architectural changes in the PR
  • Assess if documentation is complete and accurate
  • Provide findings and recommendations

Summary

The documentation in docs/ai-instructions.md has already been appropriately updated by a previous Claude review (commit 9118f5a). The updates cover the key architectural additions from this PR.

Changes Made in This PR

Architecture Changes:

  1. New IPC Handlers - Added three new IPC handlers for CLI installation management:

    • isStudioCliInstalled() - Check installation status
    • installStudioCli() - Install the CLI
    • uninstallStudioCli() - Uninstall the CLI
  2. Redux Store Enhancement - Extended installedAppsApi with:

    • New query: getStudioCliIsInstalled
    • New mutation: saveStudioCliIsInstalled
    • New cache tag: StudioCliIsInstalled
    • Improved tag granularity (split UserPreferences into UserEditor and UserTerminal)
  3. New Module Structure - Created src/modules/cli/lib/installation/ with:

    • index.ts - Platform-agnostic interface
    • darwin.ts - macOS implementation (symlink-based with sudo elevation)
    • win32.ts - Windows implementation (registry PATH modification)
  4. UI Components - Added StudioCliToggle component in settings

  5. Behavioral Changes:

    • Removed automatic CLI installation on Windows startup
    • Made CLI installation user-controlled via Settings modal

Documentation Assessment

✅ Already Documented:

  • IPC Communication Pattern section (lines 140-154) - CLI installation API examples added
  • Redux Store Architecture section (lines 166-188) - installedAppsApi endpoints documented
  • Last updated date changed to 2025-11-10

✅ No Additional Updates Needed:

The documentation already covers the essential architectural changes. While this PR adds a new module structure (src/modules/cli/lib/installation/), this level of detail is not typically documented in docs/ai-instructions.md because:

  1. Module structure is self-explanatory - The installation module follows existing patterns and doesn't introduce new architectural concepts
  2. Directory Structure section is high-level - It documents major directories (like src/modules/cli/), not subdirectories
  3. No new patterns introduced - The PR uses existing patterns (IPC handlers, RTK Query, platform-specific modules)
  4. No changes to core systems - WordPress providers, site server, build configuration, and main process architecture are unchanged

Architectural Pattern Analysis

The CLI installation feature follows existing architectural patterns:

  • Platform Abstraction Pattern - Similar to how WordPress providers work (darwin.ts/win32.ts/index.ts structure)
  • IPC Handler Pattern - Follows the standard pattern documented in lines 272-284
  • RTK Query Pattern - Uses standard query/mutation pattern like other APIs
  • Settings UI Pattern - Consistent with existing user settings components

Recommendation

No further documentation updates are needed. The changes made in commit 9118f5a are sufficient and appropriate. The PR adds a new feature using existing architectural patterns rather than introducing new patterns that would require documentation.

Issues to Address Before Merge

While the documentation is complete, the previous code reviews identified several bugs that should be fixed before merging:

  1. Critical: Wrong dialog message in uninstall confirmation (darwin.ts:70-71)
  2. Critical: Missing Sentry error tracking in uninstall function (darwin.ts:91)
  3. High: Missing error handling in Windows uninstall (win32.ts:116)
  4. High: Error handling issues in installation status check (win32.ts:97)
  5. Medium: Missing Windows user information about registry changes (studio-cli-toggle.tsx:32)

These are code quality issues, not documentation issues.

Code Review Complete ✅

I've completed a comprehensive code review of this PR, focusing on cross-platform compatibility, code quality, security, performance, and testing as requested.


Summary

This PR successfully adds a user-facing toggle in the Settings modal to install/uninstall the Studio CLI on macOS and Windows. The implementation demonstrates good architecture with platform-specific modules and proper separation of concerns. However, I've identified several issues that should be addressed before merging.


Critical Issues 🔴

1. Missing Sentry Error Tracking (darwin.ts:73-88)

The uninstallCliWithConfirmation function doesn't capture exceptions to Sentry, unlike installCliWithConfirmation (line 34). This creates inconsistent error tracking.

Recommendation: Add Sentry.captureException( error ); after line 73 in the catch block.

2. Missing Error Handling in Windows Uninstall (win32.ts:116-124)

The uninstallCli function has no try-catch block or error handling. Registry operations can fail, and errors will propagate uncaught, potentially leaving the system in an inconsistent state.

Recommendation: Wrap the function body in a try-catch block with Sentry error tracking:

export async function uninstallCli() {
  try {
    const currentPath = await getPathFromRegistry();
    // ... rest of code
  } catch ( error ) {
    Sentry.captureException( error );
    console.error( 'Failed to uninstall CLI from PATH', error );
    throw error;
  }
}

3. Incomplete Windows Uninstall (win32.ts:116-124)

The Windows uninstall only removes the PATH entry but doesn't delete the proxy batch file created at unversionedBinDirPath/studio.bat. This leaves orphaned files on the user's system.

Recommendation: Add cleanup of the batch file:

await unlink( path.join( unversionedBinDirPath, 'studio.bat' ) );

High Priority Issues 🟡

4. Error Handling: Status Check Masks Errors (win32.ts:97-113)

When checking if CLI is installed fails (e.g., registry permission errors), the function returns false and logs the error. This masks actual errors as "not installed" rather than "error checking status".

Recommendation: Consider differentiating between "not installed" and "error state". You could:

  • Add Sentry tracking: Sentry.captureException( error );
  • Return a more detailed status object
  • Or at minimum, ensure errors are properly tracked for debugging

5. Logic Issue in Uninstall Validation (darwin.ts:96-108)

The comment on line 104 says "proceed with the installation" but this is in the uninstallCli function. This is confusing. If the symlink doesn't exist (ENOENT), the function should probably return early or notify the user that the CLI is already uninstalled, rather than continuing to try to unlink a non-existent file.

Current behavior: If the file doesn't exist, the function continues and tries to unlink it (line 111), which will fail and trigger the sudo script.

Recommendation: Either fix the comment or add early return logic:

if ( isErrnoException( error ) && error.code === 'ENOENT' ) {
  // File does not exist, CLI is already uninstalled
  return;
}

6. UX: Missing Windows User Information (studio-cli-toggle.tsx:32-38)

Only macOS users see explanatory text about admin privileges. Windows users should also be informed that registry PATH modifications will occur.

Recommendation: Add platform-specific messaging for Windows:

{ isMac() && (
  <div className="a8c-body-small text-a8c-gray-700">
    { __( 'Toggling this option will prompt you for admin privileges...' ) }
  </div>
) }
{ isWindows() && (
  <div className="a8c-body-small text-a8c-gray-700">
    { __( 'Toggling this option will modify your PATH environment variable...' ) }
  </div>
) }

Medium Priority Issues 🟠

7. Security: Shell Script Lacks Validation (uninstall-studio-cli.sh:14)

The uninstall script doesn't verify that the symlink actually points to Studio CLI before removing it. Consider adding validation to prevent accidental deletion of similarly-named symlinks.

Recommendation: Add symlink target validation before removal:

if [ -L "$CLI_SYMLINK_PATH" ]; then
  TARGET=$(readlink "$CLI_SYMLINK_PATH")
  # Optionally verify TARGET matches expected Studio CLI path
  rm "$CLI_SYMLINK_PATH"
else
  echo "Warning: $CLI_SYMLINK_PATH is not a symlink"
  exit 1
fi

8. Platform Guard Inconsistency (win32.ts:127 vs 116)

The installCli function has a platform check that prevents installation on non-Windows or in development mode, but uninstallCli has no such check. This creates an asymmetry where users could accidentally call uninstall on wrong platforms.

Recommendation: Add consistent platform guard to uninstallCli:

export async function uninstallCli() {
  if ( process.platform !== 'win32' ) {
    return; // Or throw an error
  }
  // ... rest of function
}

9. Loading States Not Handled (preferences-tab.tsx:29)

The preferences tab doesn't handle loading states for the CLI installation status query. The query could be loading during initial render, which might briefly show incorrect toggle state.

Recommendation: Extract isLoading from the hook and handle it:

const { data: isCliInstalled, isLoading: isCliInstalledLoading } = useGetStudioCliIsInstalledQuery();

// Then in render:
<StudioCliToggle 
  value={ isCliInstalledSelection } 
  onChange={ setDirtyIsCliInstalled }
  disabled={ isCliInstalledLoading }
/>

Low Priority / Suggestions 🔵

10. Code Comments: Development Mode Behavior (win32.ts:127)

The installCli function returns early in development mode without explanation. Add a comment explaining why:

// Skip CLI installation in development mode as the CLI path changes frequently
if ( process.platform !== 'win32' || process.env.NODE_ENV === 'development' ) {
  return;
}

11. Code Comments: Linux Support (installation/index.ts:18)

The function returns false for Linux without explaining that CLI installation isn't yet supported on that platform. Consider adding a comment.

12. Potential Race Condition (preferences-tab.tsx:40-53)

Multiple settings mutations fire in parallel without awaiting each other (lines 41-52). While this is likely fine since they're independent operations and more efficient, it's worth noting in case ordering matters in the future.


Cross-Platform Compatibility ✅

The implementation properly separates platform-specific code:

  • macOS: Uses symlinks with sudo elevation (darwin.ts)
  • Windows: Uses registry PATH modification (win32.ts)
  • Path Handling: Properly uses path.join() and path.resolve() instead of hardcoded separators
  • Platform Checks: Appropriate use of process.platform checks throughout
  • Linux: Returns false (though undocumented as unsupported)

Minor concern: The uninstall script (uninstall-studio-cli.sh) is macOS-specific but doesn't validate the symlink target before deletion (see issue #7).


Security Assessment 🔒

Strengths:

  • ✅ IPC handlers properly exported and integrated
  • ✅ Uses sudo-prompt library for privilege elevation on macOS
  • ✅ Registry operations use proper Windows APIs
  • ✅ No hardcoded secrets or sensitive data exposure

Concerns:

Overall: Security posture is good for a desktop application. The elevated privilege operations are necessary and properly implemented.


Performance Impact ✅

Positive:

  • ✅ CLI installation queries are cached via RTK Query
  • ✅ Installation/uninstallation operations run async and don't block UI
  • ✅ Minimal bundle size impact (shell scripts are small)
  • ✅ Registry operations on Windows are fast

No performance concerns identified.


Testing Coverage 📋

Current Coverage (user-settings.test.tsx):

  • ✅ Mock properly implements isStudioCliInstalled (line 30)
  • ✅ "Studio CLI" label verified in preferences tab (line 107)
  • ✅ Good coverage of tab navigation and IPC communication

Missing Test Coverage:

  • ❌ No tests for CLI toggle interaction (clicking the toggle)
  • ❌ No tests for loading states during installation/uninstallation
  • ❌ No tests for error states when installation fails
  • ❌ No tests for the actual install/uninstall logic (darwin.ts, win32.ts)

Recommendation: Consider adding integration tests for:

  1. Toggle interaction triggers mutation
  2. Success/error dialog display
  3. Installation status updates after install/uninstall
  4. Platform-specific installation logic (may require mocking)

Code Quality & Architecture 🎯

Strengths:

  • ✅ Clean separation of concerns with platform-specific modules
  • ✅ Good use of RTK Query for state management
  • ✅ Proper IPC abstraction through preload script
  • ✅ Follows existing codebase patterns
  • ✅ Consistent naming conventions
  • ✅ Good use of TypeScript types

Areas for Improvement:


Documentation ✅

Documentation Updates:

  • docs/ai-instructions.md updated with new IPC handlers (lines 150-153)
  • ✅ RTK Query endpoints documented (lines 180-187)
  • ✅ Last modified date updated

No additional documentation updates needed.

Documentation Review Complete ✅

I've reviewed the IPC and API changes introduced in this PR and verified the existing documentation updates.


Summary

No additional documentation updates are needed. The documentation in docs/ai-instructions.md was already comprehensively updated in commit 9118f5a8.


What Was Changed in This PR

1. New IPC Handlers (src/ipc-handlers.ts:105-109)

export {
	isStudioCliInstalled,
	installStudioCli,
	uninstallStudioCli,
} from 'src/modules/cli/lib/installation';

2. New Preload API (src/preload.ts:133-135)

isStudioCliInstalled: () => ipcRendererInvoke( 'isStudioCliInstalled' ),
installStudioCli: () => ipcRendererInvoke( 'installStudioCli' ),
uninstallStudioCli: () => ipcRendererInvoke( 'uninstallStudioCli' ),

3. New RTK Query API (src/stores/installed-apps-api.ts)

  • New tag: StudioCliIsInstalled for cache invalidation
  • Improved tags: Split UserPreferences into UserEditor and UserTerminal for better granularity
  • New query: getStudioCliIsInstalled
  • New mutation: saveStudioCliIsInstalled
  • New hooks: useGetStudioCliIsInstalledQuery, useSaveStudioCliIsInstalledMutation

What's Already Documented

The documentation in docs/ai-instructions.md already includes:

Lines 150-153: CLI Installation API usage examples

// CLI Installation API (delegated to src/modules/cli/lib/installation):
window.ipcApi.isStudioCliInstalled() // Check CLI installation status
window.ipcApi.installStudioCli()     // Install the CLI
window.ipcApi.uninstallStudioCli()   // Uninstall the CLI

Lines 180-187: Complete installedAppsApi endpoints reference

// installedAppsApi endpoints (src/stores/installed-apps-api.ts):
- getStudioCliIsInstalled: Query CLI installation status
- getInstalledApps: Query installed editors and terminals
- getUserEditor: Get user's preferred editor
- getUserTerminal: Get user's preferred terminal
- saveStudioCliIsInstalled: Mutation to install/uninstall CLI
- saveUserEditor: Mutation to save preferred editor
- saveUserTerminal: Mutation to save preferred terminal

Line 370: Updated last modified date (2025-11-10)


Why This Documentation Is Sufficient

The existing documentation:

  1. Clearly shows all three new IPC handlers and their purposes
  2. Provides usage examples in the proper context (IPC Communication Pattern section)
  3. Documents the RTK Query integration pattern
  4. Explains the cache invalidation strategy using tags
  5. Follows the established documentation style and structure
  6. Is placed in the appropriate sections for discoverability

Developers working with this code will have all the information they need to:

  • Understand what the new APIs do
  • Know how to call them from the renderer process
  • Use the RTK Query hooks for React components
  • Understand the caching behavior

Missing Error Handling + Incomplete Cleanup

Two issues here:

  1. No error handling: Registry operations can fail. Add try-catch with Sentry tracking:
export async function uninstallCli() {
	try {
		const currentPath = await getPathFromRegistry();
		const newPath = currentPath
			.split( ';' )
			.filter( ( item ) => item.trim().toLowerCase() !== unversionedBinDirPath.toLowerCase() )
			.join( ';' );

		await setPathInRegistry( newPath );
		
		// 2. Clean up the batch file
		await unlink( path.join( unversionedBinDirPath, 'studio.bat' ) );
	} catch ( error ) {
		Sentry.captureException( error );
		console.error( 'Failed to uninstall CLI from PATH', error );
		throw error;
	}
}
  1. Incomplete cleanup: The function doesn't delete the proxy batch file at unversionedBinDirPath/studio.bat, leaving orphaned files.

Error Handling Masks Real Errors

When checking if CLI is installed fails (e.g., registry permission errors), the function returns false and logs the error. This masks actual errors as "not installed" rather than "error checking status".

At minimum, add Sentry tracking:

} catch ( error ) {
	console.error( 'Failed to check installation status of CLI', error );
	Sentry.captureException( error ); // ADD THIS
	return false;
}

Consider whether a more detailed status should be returned to differentiate between "not installed" and "error state".

Security: Missing Symlink Validation

The script doesn't verify that the symlink actually points to Studio CLI before removing it. Consider adding validation to prevent accidental deletion of similarly-named symlinks:

  TARGET=$(readlink "$CLI_SYMLINK_PATH")
  # Optionally verify TARGET matches expected Studio CLI path
  rm "$CLI_SYMLINK_PATH"
else
  echo >&2 "Warning: $CLI_SYMLINK_PATH is not a symlink"
  exit 1

This would prevent accidental deletion if something else creates a non-symlink file at this path.

Code Review Complete ✅

I've completed a comprehensive code review of this PR focusing on cross-platform compatibility, code quality, security, performance, and testing.


Summary

This PR successfully adds a user-facing toggle in the Settings modal to install/uninstall the Studio CLI on macOS and Windows. The implementation is generally well-structured with good separation of concerns, but I've identified several issues that should be addressed before merging.


Critical Issues 🔴

1. Missing Error Tracking in macOS Uninstall (darwin.ts:73-88)

The uninstallCliWithConfirmation function doesn't capture exceptions to Sentry, unlike installCliWithConfirmation (line 34). This creates inconsistent error tracking across the codebase.

Fix: Add Sentry.captureException( error ); after line 73 in the catch block.

2. Missing Error Handling in Windows Uninstall (win32.ts:116-124)

The uninstallCli function has no try-catch block or error handling. Registry operations can fail (permission issues, registry corruption), and errors will propagate uncaught, potentially leaving the system in an inconsistent state.

Fix: Wrap the function body in a try-catch block with Sentry error tracking:

export async function uninstallCli() {
  try {
    const currentPath = await getPathFromRegistry();
    // ... rest of code
  } catch ( error ) {
    Sentry.captureException( error );
    console.error( 'Failed to uninstall CLI from PATH', error );
    throw error;
  }
}

3. Incomplete Windows Cleanup (win32.ts:116-124)

The Windows uninstall only removes the PATH entry but doesn't delete the proxy batch file created at unversionedBinDirPath/studio.bat. This leaves orphaned files on the user's system after uninstallation.

Fix: Add cleanup of the batch file before modifying the registry.


High Priority Issues 🟡

4. Error Masking in Installation Status Check (win32.ts:97-113)

When checking if CLI is installed fails (e.g., registry permission errors), the function returns false and logs the error. This masks actual errors as "not installed" rather than "error checking status", making debugging difficult.

Fix: At minimum, add Sentry tracking to capture these errors for monitoring. Consider whether a more detailed status should be returned to differentiate between states.

5. Confusing Logic in macOS Uninstall (darwin.ts:96-108)

The comment on line 104 says "proceed with the installation" but this is in the uninstallCli function. This is confusing. Additionally, if the symlink doesn't exist (ENOENT), the function continues and tries to unlink it (line 111), which will fail unnecessarily.

Fix: Either fix the comment or add early return logic when the file doesn't exist (CLI already uninstalled).

6. Missing Windows User Information (studio-cli-toggle.tsx:32-38)

Only macOS users see explanatory text about admin privileges. Windows users should also be informed about what will happen when they toggle this option (registry PATH modifications).

Fix: Add platform-specific messaging for Windows users explaining that PATH environment variable will be modified.


Medium Priority Issues 🟠

7. Security: Shell Script Lacks Validation (uninstall-studio-cli.sh:14)

The uninstall script doesn't verify that the symlink actually points to Studio CLI before removing it. While the risk is low, consider adding validation to prevent accidental deletion of similarly-named symlinks.

Suggestion: Add symlink target validation before removal.

8. Platform Guard Inconsistency (win32.ts:127 vs 116)

The installCli function has a platform check that prevents installation on non-Windows or in development mode (line 127), but uninstallCli has no such check. This creates an asymmetry where users could accidentally call uninstall on wrong platforms.

Fix: Add consistent platform guard to uninstallCli.

9. Loading States Not Handled (preferences-tab.tsx:29)

The preferences tab doesn't handle loading states for the CLI installation status query. The query could be loading during initial render, which might briefly show incorrect toggle state.

Suggestion: Extract isLoading from the hook and disable the toggle during loading.


Low Priority / Suggestions 🔵

10. Code Documentation: Development Mode (win32.ts:127)

The installCli function returns early in development mode without explanation. Add a comment explaining why CLI installation is skipped in dev mode.

11. Code Documentation: Linux Support (installation/index.ts:18)

The function returns false for Linux without explaining that CLI installation isn't yet supported on that platform. Consider adding a comment.

12. Potential Race Condition (preferences-tab.tsx:40-53)

Multiple settings mutations fire in parallel without awaiting each other (lines 41-52). While this is likely fine since they're independent operations and more efficient, it's worth noting in case ordering matters in the future.


Cross-Platform Compatibility ✅

The implementation properly separates platform-specific code:

  • macOS: Uses symlinks with sudo elevation (darwin.ts)
  • Windows: Uses registry PATH modification (win32.ts)
  • Path Handling: Properly uses path.join() and path.resolve() instead of hardcoded separators
  • Platform Checks: Appropriate use of process.platform checks throughout
  • Linux: Returns false (though undocumented as unsupported)

Minor concern: The uninstall script is macOS-specific but doesn't validate the symlink target before deletion.


Security Assessment 🔒

Strengths:

  • ✅ IPC handlers properly exported and integrated
  • ✅ Uses sudo-prompt library for privilege elevation on macOS
  • ✅ Registry operations use proper Windows APIs
  • ✅ No hardcoded secrets or sensitive data exposure

Concerns:

Performance Impact ✅

  • ✅ CLI installation queries are cached via RTK Query
  • ✅ Installation/uninstallation operations run async and don't block UI
  • ✅ Minimal bundle size impact

  • ✅ Mock properly implements isStudioCliInstalled (line 30)
  • ✅ "Studio CLI" label verified in preferences tab (line 107)
  • ✅ Good coverage of tab navigation and IPC communication

  • ❌ No tests for loading states during installation/uninstallation
  • ❌ No tests for error states when installation fails
  • ❌ No tests for the actual install/uninstall logic (darwin.ts, win32.ts)

Recommendation: Consider adding integration tests for toggle interaction, success/error dialog display, and installation status updates.


Code Quality & Architecture 🎯

Strengths:

  • ✅ Clean separation of concerns with platform-specific modules

I've reviewed the IPC and API changes in this PR and assessed the documentation.

Todo List

  • Read current documentation state
  • Review IPC handler changes (src/ipc-handlers.ts)
  • Review preload API changes (src/preload.ts)
  • Review RTK Query changes (src/stores/installed-apps-api.ts)
  • Assess if documentation updates are needed
  • Provide findings

Documentation Review Complete ✅

No additional documentation updates are needed. The documentation in docs/ai-instructions.md was already comprehensively updated in commit 9118f5a8.

Changes Made in This PR

1. New IPC Handlers (src/ipc-handlers.ts:105-109)

Three new CLI installation handlers were added:

  • isStudioCliInstalled() - Check CLI installation status
  • installStudioCli() - Install the CLI
  • uninstallStudioCli() - Uninstall the CLI

2. New Preload API (src/preload.ts:133-135)

The preload script now exposes these handlers to the renderer:

isStudioCliInstalled: () => ipcRendererInvoke( 'isStudioCliInstalled' ),
installStudioCli: () => ipcRendererInvoke( 'installStudioCli' ),
uninstallStudioCli: () => ipcRendererInvoke( 'uninstallStudioCli' ),

3. RTK Query API (src/stores/installed-apps-api.ts)

The installedAppsApi was enhanced with:

  • New tag: StudioCliIsInstalled for cache invalidation
  • Improved tags: Split UserPreferences into UserEditor and UserTerminal for better granularity
  • New query: getStudioCliIsInstalled (line 32)
  • New mutation: saveStudioCliIsInstalled (line 69)
  • New hooks: useGetStudioCliIsInstalledQuery, useSaveStudioCliIsInstalledMutation

What's Already Documented

The documentation already includes all essential information:

Lines 150-153: CLI Installation API usage examples in IPC Communication Pattern section
Lines 180-187: Complete installedAppsApi endpoints reference in Redux Store Architecture section
Line 370: Updated last modified date (2025-11-10)

The documentation covers:

  • All three new IPC handlers with clear descriptions
  • Usage examples showing how to call them from renderer
  • RTK Query integration details
  • Cache invalidation strategy
  • Hook names for React components

Why This Is Sufficient

The existing documentation provides everything developers need to:

  1. Understand what the new APIs do
  2. Know how to call them from the renderer process
  3. Use the RTK Query hooks in React components
  4. Understand the caching behavior and tag invalidation

No further updates are needed because:

  • The PR follows existing architectural patterns (no new patterns introduced)

Documentation Review for IPC Changes ✅

Todo List:

  • Read current documentation state
  • Review IPC handler changes (src/ipc-handlers.ts)
  • Review preload API changes (src/preload.ts)
  • Review RTK Query changes (src/stores/installed-apps-api.ts)
  • Assess if documentation updates are needed
  • Provide findings

Documentation Assessment Complete

No additional documentation updates are needed. The documentation in docs/ai-instructions.md was already comprehensively updated in commit 9118f5a8.

Changes Made in This PR

1. New IPC Handlers (src/ipc-handlers.ts:105-109)

Three new CLI installation handlers were added:

  • isStudioCliInstalled() - Check CLI installation status
  • installStudioCli() - Install the CLI
  • uninstallStudioCli() - Uninstall the CLI

2. New Preload API (src/preload.ts:133-135)

The preload script now exposes these handlers to the renderer:

isStudioCliInstalled: () => ipcRendererInvoke( 'isStudioCliInstalled' ),
installStudioCli: () => ipcRendererInvoke( 'installStudioCli' ),
uninstallStudioCli: () => ipcRendererInvoke( 'uninstallStudioCli' ),

3. RTK Query API (src/stores/installed-apps-api.ts)

The installedAppsApi was enhanced with:

  • New tag: StudioCliIsInstalled for cache invalidation (line 30)
  • New query: getStudioCliIsInstalled (lines 32-38)
  • New mutation: saveStudioCliIsInstalled (lines 69-79)
  • New hooks: useGetStudioCliIsInstalledQuery, useSaveStudioCliIsInstalledMutation (lines 103-104)

What's Already Documented

The documentation already includes all essential information:

Lines 150-153: CLI Installation API usage examples in IPC Communication Pattern section
Lines 180-187: Complete installedAppsApi endpoints reference in Redux Store Architecture section
Line 370: Updated last modified date (2025-11-10)

The documentation covers:

  • All three new IPC handlers with clear descriptions
  • Usage examples showing how to call them from renderer
  • RTK Query integration details including the new CLI endpoints
  • Cache invalidation strategy with the new StudioCliIsInstalled tag
  • Hook names for React components

Why This Is Sufficient

The existing documentation provides everything developers need to:

  1. Understand what the new APIs do
  2. Know how to call them from the renderer process
  3. Use the RTK Query hooks in React components
  4. Understand the caching behavior and tag invalidation

No further updates are needed because:

  • The PR follows existing architectural patterns (no new patterns introduced)
  • Implementation details are appropriately abstracted (platform-specific code in src/modules/cli/lib/installation/ doesn't need to be in high-level docs)
  • The documentation follows the established style and is placed in the correct sections
  • No changes were made to core systems (WordPress providers, site server, build config)

Previous Review Issues

Note that previous Claude code reviews identified several bugs that should be addressed (unrelated to documentation):

  1. Missing Sentry error tracking in macOS uninstall
  2. Missing error handling in Windows uninstall
  3. Incomplete Windows cleanup (batch file not deleted)
  4. Error masking in installation status checks

These are code quality issues, not documentation issues.

Architecture Documentation Review Complete ✅

I've reviewed the architectural changes in this PR and assessed the documentation updates.

Todo List:

  • Read current documentation state
  • Review architectural changes in the PR
  • Assess if documentation is complete and accurate
  • Provide findings and recommendations

Summary

The documentation in docs/ai-instructions.md has already been appropriately updated by a previous Claude review (commit 9118f5a). The updates cover the key architectural additions from this PR.

Changes Made in This PR

Architecture Changes:

  1. New IPC Handlers - Added three new IPC handlers for CLI installation management:

    • isStudioCliInstalled() - Check installation status
    • installStudioCli() - Install the CLI
    • uninstallStudioCli() - Uninstall the CLI
  2. Redux Store Enhancement - Extended installedAppsApi with:

    • New query: getStudioCliIsInstalled
    • New mutation: saveStudioCliIsInstalled
    • New cache tag: StudioCliIsInstalled
    • Improved tag granularity (split UserPreferences into UserEditor and UserTerminal)
  3. New Module Structure - Created src/modules/cli/lib/installation/ with:

    • index.ts - Platform-agnostic interface
    • macos.ts - macOS implementation (symlink-based with sudo elevation)
    • windows.ts - Windows implementation (registry PATH modification)
  4. UI Components - Added StudioCliToggle component in settings

  5. Behavioral Changes:

    • Removed automatic CLI installation on Windows startup
    • Removed "Install CLI..." menu item on macOS
    • Made CLI installation user-controlled via Settings modal

Documentation Assessment

✅ Already Documented:

  • IPC Communication Pattern section (lines 140-154) - CLI installation API examples added
  • Redux Store Architecture section (lines 166-188) - installedAppsApi endpoints documented
  • Last updated date changed to 2025-11-10

✅ No Additional Updates Needed:

The documentation already covers the essential architectural changes. While this PR adds a new module structure (src/modules/cli/lib/installation/), this level of detail is not typically documented in docs/ai-instructions.md because:

  1. Module structure is self-explanatory - The installation module follows existing patterns and doesn't introduce new architectural concepts
  2. Directory Structure section is high-level - It documents major directories (like src/modules/cli/), not subdirectories
  3. No new patterns introduced - The PR uses existing patterns (IPC handlers, RTK Query, platform-specific modules)
  4. No changes to core systems - WordPress providers, site server, build configuration, and main process architecture are unchanged

Architectural Pattern Analysis

The CLI installation feature follows existing architectural patterns:

  • Platform Abstraction Pattern - Similar to how WordPress providers work (macos.ts/windows.ts/index.ts structure)
  • IPC Handler Pattern - Follows the standard pattern documented in lines 272-284
  • RTK Query Pattern - Uses standard query/mutation pattern like other APIs
  • Settings UI Pattern - Consistent with existing user settings components

Recommendation

No further documentation updates are needed. The changes made in commit 9118f5a are sufficient and appropriate. The PR adds a new feature using existing architectural patterns rather than introducing new patterns that would require documentation.

Issues to Address Before Merge

While the documentation is complete, the previous code reviews identified several bugs that should be fixed before merging:

  1. Critical: Missing Sentry error tracking in uninstall function (macos.ts:73-88)
  2. Critical: Missing error handling in Windows uninstall (windows.ts:116-124)
  3. High: Incomplete Windows cleanup - batch file not deleted (windows.ts:116-124)
  4. High: Error handling issues in installation status check (windows.ts:97-113)
  5. Medium: Missing Windows user information about registry changes (studio-cli-toggle.tsx)

These are code quality issues, not documentation issues.

Looks great and works as expected 👍 Just left a few comments which I wonder.

I haven't seen prefix dirty for such cases. Just wonder - did you noticed that it's used somewhere outside YOLO/A8C? We can make it an agreement for such cases.

await setPathInRegistry( newPath );
} catch ( error ) {
Sentry.captureException( error );
console.error( 'Failed to uninstall CLI', error );

Not critical, but WDYT about throwing error outside to render it instead of console.log?

Looking at installation folder, it seems that we could go with factory class and automatically create instalce of it depending on OS, as a result we coudl avoid such things as if ( process.platform !== 'win32' ) { here, unify function names, less conditions, etc. I see that we export only install/uninstall/is functions from there, so we won't have Liskov substitution principle issues and it will be more structured and easy in the future to add other OS if we need.

No action needed, just wondering your opinion as you know the codebase better and I would like to understand :)

@fredrikekelund I see it follows the design, but shouldn't the radio button be placed on the left in LTR language? It's a bit weird UI now.
