Documents the expected behavior and ensures browser helper filtering works correctly:
- Tests browser-specific error messages when main browser isn't running
- Verifies successful capture when main browser is found (not helpers)
- Documents the problem this fixes (no more confusing 'no capturable windows' errors)
- Ensures non-browser applications continue to work normally

Adds support for capturing the frontmost window of the frontmost application
instead of falling back to screen capture mode.
Changes:
- Added 'frontmost' case to CaptureMode enum in Swift CLI
- Implemented captureFrontmostWindow() method using NSWorkspace.shared.frontmostApplication
- Updated TypeScript to use --mode frontmost instead of defaulting to screen mode
- Added comprehensive test coverage for frontmost functionality
- Updated existing tests to reflect new behavior
The frontmost mode now:
1. Detects the currently active application
2. Captures only its frontmost window (index 0)
3. Returns a single image file with proper metadata

Fixes issue where item_type: '' was not properly defaulting to the correct operation.
Empty strings and whitespace-only strings now fall back to the proper default logic:
- If app is provided: defaults to 'application_windows'
- If no app: defaults to 'running_applications'

- Make window specifiers case-insensitive (WINDOW_TITLE, window_title, Window_Title)
- Add comprehensive test coverage for empty/null provider_config scenarios
- Improve error handling to prevent spread operator failures on undefined _meta

Addresses critical edge case where malformed app targets with multiple leading colons
(e.g., "::::::::::::::::Finder") created empty app names that would match ALL system
processes. This could potentially expose sensitive information or cause unintended
system-wide captures.
Key improvements:
- Enhanced app target parsing to validate non-empty app names
- Added fallback logic to extract valid app names from malformed inputs
- Default to screen mode when all parts are empty (security-first approach)
- Comprehensive test coverage for edge cases
- Improved backward compatibility with hidden path parameters

When users search for windows with URLs containing ports (e.g., 'http://example.com:8080'),
the system now provides much better debugging information when the window isn't found.
Key improvements:
- Enhanced window not found errors now list all available window titles
- Added specific guidance for URL-based searches (try without protocol)
- New CaptureError.windowTitleNotFound with detailed debugging info
- Comprehensive test coverage for colon parsing in app targets
- Better error messages help users understand why matching failed
Example improved error:
"Window with title containing 'http://example.com:8080' not found in Google Chrome.
Available windows: 'example.com:8080 - Google Chrome', 'New Tab - Google Chrome'.
Note: For URLs, try without the protocol (e.g., 'example.com:8080' instead of 'http://example.com:8080')."
This addresses the common issue where browsers display simplified URLs in window titles
without the protocol, making it easier for users to find the correct matching pattern.

Previously, path traversal attempts like `../../../../../../../etc/passwd` were incorrectly
reported as screen recording permission errors instead of file system errors.
Changes:
- Modified ScreenCapture error handling to distinguish between CaptureError types and ScreenCaptureKit errors
- CaptureError.fileWriteError now bypasses screen recording permission detection
- Added path validation in OutputPathResolver to detect and log path traversal attempts
- Added logging for system-sensitive path access attempts
- Comprehensive test coverage for various path traversal patterns and error scenarios
This ensures users get accurate error messages that guide them to the actual problem
(invalid paths, missing directories, file permissions) rather than misleading
screen recording permission prompts.

When multiple applications have exact matches (e.g., "claude" and "Claude"), the system now:
- Captures all windows from all matching applications instead of throwing an ambiguous match error
- Maintains sequential window indices across all matched applications
- Preserves original application names in saved file metadata
- Only returns errors for truly ambiguous fuzzy matches
This provides more useful behavior for common scenarios where users have multiple apps with
similar names (different case, etc.) and want to capture windows from all of them.
Updates:
- Added `captureWindowsFromMultipleApps` method to handle multi-app capture logic
- Modified error handling in both single window and multi-window capture modes
- Updated documentation (spec.md, CHANGELOG.md) to reflect new behavior
- Comprehensive test suite covering various multiple match scenarios

- Invalid screen index (e.g., screen:99) now properly falls back to capturing all screens with unique filenames
- String "null" in path parameter is now correctly treated as undefined instead of literal path
- Added fallback-aware filename generation to prevent file overwrites when screen index is out of bounds
- Comprehensive test coverage for both edge cases

Implements robust handling for invalid image formats (like 'bmp', 'gif', 'webp') that bypass schema validation:
- Added defensive format validation in image tool handler
- Automatic path correction to ensure file extensions match actual format used
- Warning messages in response when format fallback occurs
- Comprehensive unit and integration test coverage for edge cases
This ensures invalid formats automatically fall back to PNG as requested, preventing
Swift CLI rejection and incorrect file extensions in output paths.

- Add preprocessing to handle JSON string arrays from MCP clients
- Support multiple input formats: JSON string, comma-separated, single value
- Handle empty strings and null/undefined values gracefully
- Add comprehensive test coverage for all parsing scenarios
- Fixes "Expected array, received string" error when MCP clients send JSON string arrays
This resolves the issue shown in the test screenshot where include_window_details
was sent as '["ids", "bounds", "off_screen"]' (JSON string) instead of a proper array.
