fix: improve Claude CLI detection and add installation selector

[AndyMik90]

Summary

This PR addresses the "Claude Code not found" error when starting tasks by improving CLI path detection across all platforms.

Backend changes:

• Add cross-platform find_claude_cli() function in client.py that checks:
  • CLAUDE_CLI_PATH environment variable for user override
  • System PATH via shutil.which()
  • Homebrew paths on macOS
  • NVM paths for Node.js version manager installations
  • Platform-specific standard locations (Windows: AppData, Program Files; Unix: .local/bin)
• Pass detected cli_path to ClaudeAgentOptions in both create_client() and create_simple_client()
• Improve Windows .cmd/.bat file execution using proper cmd.exe flags (/d, /s, /c) and correct quoting for paths with spaces

Frontend changes:

• Add IPC handlers for scanning all Claude CLI installations and switching active path
• Update ClaudeCodeStatusBadge to show current CLI path and allow selection when multiple installations are detected
• Add writeSettingsFile() to settings-utils for persisting CLI path selection
• Add translation keys for new UI elements (English and French)

Test plan

• Test on macOS with Claude CLI installed via npm global
• Test on macOS with Claude CLI installed via Homebrew
• Test on Windows with Claude CLI in AppData
• Test on Windows with Claude CLI in Program Files
• Test with multiple Claude CLI installations and verify switching works
• Verify the CLI path is displayed in the ClaudeCodeStatusBadge popup

Closes #1001

Summary by CodeRabbit

• New Features

  • Added Claude CLI discovery to detect multiple installations on your system
  • Enable switching between different Claude CLI installations with a new installation selector
  • Display active installation path and version in the status badge

📝 Walkthrough

Walkthrough

The PR implements cross-platform Claude CLI detection, validation, and user-selectable installation management. The backend adds thread-safe caching and discovery across PATH, Homebrew, NVM, and platform-specific locations. The frontend introduces IPC handlers for scanning installations, validating paths, persistent settings storage, and UI components for switching between detected CLI versions with i18n support.

Through NVM trees and Homebrew's mark,
Cached with locks so thread-safe and sound,
The best Claude CLI installation found! ✨
Switch it quick with a warning's guard,
Settings saved—our work's not hard. 🎯

🤖 Fix all issues with AI agents

In @apps/backend/core/client.py:
- Around line 136-174: The _get_claude_detection_paths function currently omits
several Unix candidate paths present in the frontend; update it to include
additional platform_paths entries for "~/.npm-global/bin/claude",
"~/.yarn/bin/claude", "~/.claude/local/claude", and "~/node_modules/.bin/claude"
(expand via Path.home()) so the returned dict (keys "homebrew", "platform",
"nvm_versions_dir") matches the frontend scanClaudeInstallations behavior.

In @apps/frontend/src/main/ipc-handlers/claude-code-handlers.ts:
- Around line 150-165: The NVM scanning loop may iterate all Node versions
(versionDirs) causing slow startup; after obtaining and sorting versionDirs via
sortNvmVersionDirs, limit the list to the top N (e.g., const MAX_NVM_VERSIONS =
5; const limited = versionDirs.slice(0, MAX_NVM_VERSIONS)) and iterate over that
limited array when calling addInstallation(nvmClaudePath, 'nvm'), keeping
sortNvmVersionDirs and addInstallation unchanged; add a small comment explaining
the limit and make MAX_NVM_VERSIONS a constant so it can be tuned.
- Around line 167-187: The platform-specific paths array (platformPaths) is
incorrectly labelled with source 'system-path' when passed to addInstallation;
change those addInstallation calls to use a new source like 'standard-location'
(or 'platform-default') instead of 'system-path', and update the
ToolDetectionResult['source'] type union to include 'standard-location' so the
compiler accepts the new value; ensure all usages of addInstallation that truly
mean PATH discovery still use 'system-path' and update any related tests/types
if present.

In @apps/frontend/src/main/settings-utils.ts:
- Around line 53-57: The existsSync(dir) pre-check is redundant and can be
removed because mkdirSync(dir, { recursive: true }) already creates the
directory if missing and does not error if it exists; update the block around
settingsPath/dir to call mkdirSync(path.dirname(settingsPath), { recursive: true
}) directly (remove the existsSync and its conditional) so only mkdirSync is
used, keeping path.dirname, mkdirSync, and settingsPath references intact.

In @apps/frontend/src/renderer/components/ClaudeCodeStatusBadge.tsx:
- Around line 580-588: The Windows path issue is that
installation.path.split('/') only handles POSIX slashes; update the display
logic in ClaudeCodeStatusBadge (where installation.path is sliced to last two
segments) to split on both forward and backslashes (e.g., use a regex like
/[\\/]/) and trim empty segments before taking slice(-2), then join with the
original separator or '/' for display, falling back to installation.path if no
segments found so the last-two-segment extraction works cross-platform.
- Around line 550-594: The label element is not associated with the Select
control; add an explicit association by giving the Select an id (e.g.,
id={`installation-select`}) and set the label’s htmlFor to the same id, or if
the Select component does not forward id props, wrap the Select (Select +
SelectTrigger/SelectValue) inside the label or use aria-labelledby to point to
the label id; update the JSX around the Select, SelectTrigger and SelectValue
accordingly and keep handleInstallationSelect/selectedInstallation behavior
unchanged.

apps/frontend/src/main/settings-utils.ts (1)

12-12: LGTM!

Import additions are appropriate for the new writeSettingsFile function.

apps/frontend/src/shared/constants/ipc.ts (1)

510-511: LGTM!

The new IPC channels follow the established naming conventions and are logically placed within the Claude Code CLI operations section.

apps/frontend/src/shared/types/cli.ts (1)

52-76: LGTM!

The new types are well-documented, properly typed, and appropriately handle edge cases (nullable version for validation failures, nullable activePath when no installation is configured). Reusing ToolDetectionResult['source'] ensures consistency with existing detection sources.

apps/frontend/src/shared/types/ipc.ts (1)

772-773: LGTM!

The new API method signatures are correctly typed, follow the established patterns for Claude Code operations, and properly use the IPCResult wrapper for consistent error handling.

apps/frontend/src/shared/i18n/locales/en/navigation.json (1)

44-69: LGTM!

The new translation keys are well-named and provide clear, user-friendly text. The warning descriptions appropriately inform users about the behavior when switching installations.

apps/frontend/src/shared/i18n/locales/fr/navigation.json (1)

44-69: LGTM!

French translations are complete and match all the new English keys. The translations are grammatically appropriate and consistent with the existing French locale style. Based on learnings, both EN and FR locales are correctly updated.

apps/frontend/src/main/ipc-handlers/claude-code-handlers.ts (3)

36-81: LGTM! Well-structured async CLI validation with proper Windows handling.

The implementation correctly:

• Uses ComSpec or falls back to SystemRoot\System32\cmd.exe for Windows GUI launch edge cases (per PR objective)
• Applies proper /d /s /c flags and double-quoting for paths with spaces
• Sets a 5-second timeout to prevent hangs
• Augments PATH with the CLI directory for proper resolution

---

87-113: LGTM! Clean deduplication and validation logic.

The addInstallation helper properly normalizes paths via path.resolve(), checks for duplicates, validates executability before adding, and correctly marks the active installation.

---

956-996: LGTM! Robust path activation with proper validation and persistence.

The handler correctly:

• Validates existence before proceeding
• Validates the CLI is executable via validateClaudeCliAsync
• Persists to settings via writeSettingsFile
• Updates the CLI tool manager cache via configureTools
• Provides clear error messages

apps/frontend/src/preload/api/modules/claude-code-api.ts (2)

56-75: LGTM! Consistent result type definitions.

The new result interfaces follow the established pattern with success, data?, and error? fields, matching other result types in this file.

---

103-138: LGTM! Clean API surface extension.

The new methods are properly typed and follow the existing IPC invocation pattern. The interface documentation clearly describes the purpose of each method.

apps/frontend/src/renderer/components/ClaudeCodeStatusBadge.tsx (5)

69-75: LGTM! Well-organized state declarations for installation management.

The new state variables follow the established patterns in this component and properly handle loading, error, and selection states.

---

130-152: LGTM! Consistent data fetching pattern.

The fetchInstallations callback follows the same pattern as fetchVersions, with proper loading state management, error handling, and API availability checks.

---

242-274: LGTM! Clean path switching implementation.

The performPathSwitch function properly:

• Guards against null selection
• Manages loading state
• Clears errors before operation
• Refreshes both version and installations after success
• Handles errors with clear messages

---

682-708: LGTM! Well-structured path change confirmation dialog.

The dialog properly:

• Uses i18n translation keys for all text (per coding guidelines)
• Shows the selected path for user confirmation
• Clears selection on cancel
• Triggers the switch on confirm

---

173-178: Verify the refresh behavior after path switch to ensure the updated active installation is properly reflected.

The effect only fetches installations when installations.length === 0. After performPathSwitch() calls fetchInstallations(), the installations array becomes populated. If the user closes the popover and reopens it later, the effect won't refetch since the array is no longer empty, potentially displaying stale data if the system's installations change. While the active status is updated immediately after a path switch via the fetchInstallations() call at line 262, subsequent reopens of the popover won't show updates unless the user switches paths again.

Consider either:

• Clearing the installations array when path switch completes (calling setInstallations([]) before the timeout in performPathSwitch)
• Using a needsRefresh flag that forces a refetch independent of array length, similar to how manual refresh works via the Refresh button

apps/frontend/src/renderer/lib/browser-mock.ts (1)

263-280: LGTM! Appropriate mock implementation for browser development.

The mock responses correctly match the ClaudeInstallationList and ClaudeInstallationInfo type shapes, enabling UI development and testing without Electron.

apps/backend/core/simple_client.py (2)

29-29: LGTM! Correct import of CLI detection function.

Importing find_claude_cli from core.client follows the established pattern and ensures consistent CLI detection across both create_client and create_simple_client factories.

---

88-106: LGTM! Clean integration of CLI path detection.

The implementation correctly:

• Calls find_claude_cli() to detect the CLI path
• Builds options as a dictionary for flexibility
• Only adds cli_path when found (avoiding None values)
• Follows the same pattern established in core.client.create_client

This aligns with the coding guidelines requiring use of the Claude Agent SDK via create_client() patterns.

apps/backend/core/client.py (6)

126-134: LGTM! Well-structured cache with thread safety.

The CLI cache follows the same pattern as the project index cache above, using a dedicated lock for thread-safe access. The comment clearly explains the purpose and references frontend consistency.

---

177-237: LGTM! Robust CLI validation with proper Windows handling.

The validation function correctly:

• Uses ComSpec environment variable or constructs the default cmd.exe path
• Applies /d /s /c flags for safe command execution
• Uses CREATE_NO_WINDOW to prevent console window flashing
• Sets a 5-second timeout to avoid hangs

This properly addresses the PR objective of fixing Windows GUI-launch edge cases where cmd.exe is not resolvable from PATH.

240-350: LGTM! Comprehensive CLI detection with proper priority order.

The find_claude_cli function implements the detection priority correctly:

1. Environment variable override (user control)
2. System PATH (most common case)
3. Homebrew paths (macOS-specific)
4. NVM paths (Node version manager)
5. Platform-specific standard locations

The caching with thread-safe access ensures efficient repeated calls, and the warning message guides users on installation.

---

353-357: LGTM! Cache invalidation utility.

The clear_claude_cli_cache function provides a clean way to force re-detection, which is useful after installation or configuration changes.

---

1019-1026: LGTM! Helpful diagnostic output for CLI detection.

The print statements provide clear feedback about CLI detection status, helping with debugging installation issues.

---

1051-1053: LGTM! Proper conditional CLI path injection.

The cli_path is only added to options when found, avoiding passing None to the SDK. This follows the same pattern used in simple_client.py.

🧹 Nitpick | 🔵 Trivial

Minor inconsistency: Backend missing some platform paths that frontend has.

The frontend's scanClaudeInstallations includes additional paths like ~/.npm-global/bin/claude, ~/.yarn/bin/claude, ~/.claude/local/claude, and ~/node_modules/.bin/claude for Unix systems. Consider adding these for consistency.

Additional Unix paths to consider

     else:
         platform_paths = [
             str(home_dir / ".local" / "bin" / "claude"),
             str(home_dir / "bin" / "claude"),
+            str(home_dir / ".npm-global" / "bin" / "claude"),

🧹 Nitpick | 🔵 Trivial

Consider limiting NVM version scanning for performance.

The NVM scanning iterates through all Node version directories and validates each Claude CLI found. On systems with many NVM versions, this could be slow. Consider adding a limit (e.g., top 5 most recent versions) similar to how the frontend limits npm version fetching.

Suggested optimization

         const versionDirs = sortNvmVersionDirs(entries);
-        for (const versionName of versionDirs) {
+        // Limit to 5 most recent NVM versions to avoid slow scans
+        for (const versionName of versionDirs.slice(0, 5)) {
           const nvmClaudePath = path.join(nvmDir, versionName, 'bin', 'claude');

⚠️ Potential issue | 🟡 Minor

Incorrect source attribution for platform-specific paths.

Platform-specific standard locations (lines 168-183) are being attributed as 'system-path', but this is semantically incorrect. These are user-specific or known install locations, not paths discovered via the system PATH. Consider using a more accurate source like 'standard-location' or 'platform-default'.

Suggested fix

   for (const p of platformPaths) {
-    await addInstallation(p, 'system-path');
+    await addInstallation(p, 'standard-location');
   }

Note: This would require adding 'standard-location' to the ToolDetectionResult['source'] type union in apps/frontend/src/shared/types/cli.ts.

🧹 Nitpick | 🔵 Trivial

Redundant existence check before mkdirSync({ recursive: true }).

The existsSync(dir) check is unnecessary—mkdirSync with { recursive: true } already handles existing directories without throwing an error. This also introduces a minor TOCTOU window (though not a practical concern here).

♻️ Suggested simplification

-  // Ensure the directory exists
-  const dir = path.dirname(settingsPath);
-  if (!existsSync(dir)) {
-    mkdirSync(dir, { recursive: true });
-  }
+  // Ensure the directory exists

⚠️ Potential issue | 🟡 Minor

Fix accessibility: Label must be associated with a control.

The static analysis correctly identifies that the label at line 553-555 is not associated with a form control. While the Select component immediately follows, the <label> element needs an explicit association.

Suggested fix using htmlFor and id

           <div className="space-y-1.5">
-            <label className="text-xs text-muted-foreground">

             <Select
+              id="installation-selector"
               value={selectedInstallation || ""}

Note: If the Select component from your UI library doesn't forward the id prop, you may need to wrap the label around the control or use aria-labelledby instead.

CLI tool config replacement loses other tool paths

Medium Severity

The call to configureTools({ claudePath: cliPath }) passes only the claudePath property. However, the configure() method in cli-tool-manager.ts performs a full replacement of userConfig rather than a merge. If the user had previously configured custom paths for other tools (python, git, gh), those configurations are lost when switching Claude CLI installations. The handler needs to preserve existing tool configurations by reading the current config and merging the new claudePath into it.

🟡 [a8b29ba9864e] [MEDIUM] Windows cmd.exe command line may be vulnerable to injection via malicious paths

📁 apps/backend/core/client.py:208

The _validate_claude_cli() function constructs a command line string that is passed to subprocess.run(). While the path is double-quoted, the /s flag combined with double-double-quote quoting can be exploited. A path containing characters like quote-ampersand-malicious_command could break out of quotes. The path comes from CLAUDE_CLI_PATH environment variable or detection paths.

Suggested fix:

Add path sanitization before constructing the command line. Validate that paths don't contain shell metacharacters.

🟡 [3160daf5df48] [MEDIUM] IPC handler lacks path security validation before CLI execution

📁 apps/frontend/src/main/ipc-handlers/claude-code-handlers.ts:959

The CLAUDE_CODE_SET_ACTIVE_PATH IPC handler accepts a user-provided cliPath parameter and passes it directly to validateClaudeCliAsync() which executes the path. While existsSync(cliPath) is checked, there's no validation for directory traversal, shell metacharacters, or path security.

Suggested fix:

Add path security validation before executing. Consider using path normalization and checking for directory traversal or shell metacharacters.

🟡 [dd386470921a] [MEDIUM] Path display truncation uses forward slash regardless of platform

📁 apps/frontend/src/renderer/components/ClaudeCodeStatusBadge.tsx:582

The code uses installation.path.split('/').slice(-2).join('/') to display a truncated path. On Windows, paths use backslashes, so this split will fail. A Windows path will not split on '/' and will show the full path instead of the truncated version.

Suggested fix:

Split on both path separators using a regex: installation.path.split(/[\/\\]/).slice(-2).join('/')

🟡 [dea924530e26] [MEDIUM] Validation errors are silently swallowed without logging

📁 apps/frontend/src/main/ipc-handlers/claude-code-handlers.ts:78

The catch block in validateClaudeCliAsync() catches all errors but returns [false, null] without any logging. This silently hides validation failures including permission issues, timeouts, or system errors, making debugging CLI detection problems difficult.

Suggested fix:

Add error logging: console.warn('[Claude Code] CLI validation failed for', cliPath, ':', error);

🟡 [52335e227caf] [MEDIUM] Nullable version type not handled in UI rendering

📁 apps/frontend/src/renderer/components/ClaudeCodeStatusBadge.tsx:585

The ClaudeInstallationInfo.version field is typed as string | null, but in the component it's rendered as v{installation.version} without null checking. If version validation fails, this will display 'vnull' in the UI.

Suggested fix:

Add null check: {installation.version ? `v${installation.version}` : 'version unknown'}

🟠 [10359704872b] [HIGH] scanClaudeInstallations duplicates existing detection logic from cli-tool-manager

📁 apps/frontend/src/main/ipc-handlers/claude-code-handlers.ts:87

The scanClaudeInstallations() function reimplements CLI detection that already exists in cli-tool-manager.ts (detectClaude() and detectClaudeAsync()). Both enumerate the same paths and perform validation. This creates maintenance burden and risk of drift between implementations.

Suggested fix:

Refactor to extend cli-tool-manager.ts with a scanAllClaudePaths() function. Use getClaudeDetectionPaths() as the single source of truth.

🟡 [df80ec4e39be] [MEDIUM] Settings persistence pattern differs from established handler pattern

📁 apps/frontend/src/main/ipc-handlers/claude-code-handlers.ts:974

The CLAUDE_CODE_SET_ACTIVE_PATH handler uses writeSettingsFile() with readSettingsFile() || {}. The established pattern in settings-handlers.ts merges with DEFAULT_APP_SETTINGS before saving. This could lose type safety and default values.

Suggested fix:

Use established pattern: merge with DEFAULT_APP_SETTINGS before saving to preserve type safety and defaults.

🟡 [f9a389a323b7] [MEDIUM] Backend CLI detection duplicates frontend logic without shared configuration

📁 apps/backend/core/client.py:136

The backend's _get_claude_detection_paths() mirrors the frontend's getClaudeDetectionPaths() in cli-tool-manager.ts. While cross-language duplication is sometimes unavoidable, there's no mechanism to ensure they stay synchronized.

Suggested fix:

Add cross-reference comments in both files. Consider shared config file or tests verifying path lists stay synchronized.
