chore: bump version to 1.0.0-beta.13

 ## [Unreleased]
 
+## [1.0.0-beta.13] - 2025-01-08
+
+### Added
+- Comprehensive local-only test framework for testing actual screenshot functionality
+- SwiftUI test host application for controlled testing environment
+- Screenshot validation tests including content validation and visual regression
+- Performance benchmarking tests for capture operations
+- Multi-display capture tests
+- Test infrastructure for permission dialog testing
+
+### Improved
+- The `list` tool with `item_type: 'running_applications'` now intelligently filters its results to only show applications that have one or more windows. This provides a cleaner, more relevant list for a screenshot utility by default, hiding background processes that have no user interface.
+- Test coverage with local-only tests that can validate actual capture functionality
+- Test organization with new tags: `localOnly`, `screenshot`, `multiWindow`, `focus`
+
+### Fixed
+- Fixed a bug where calling the `image` tool without any arguments would incorrectly result in a "Failed to write to file" error. The tool now correctly creates and uses a temporary file, returning the capture as Base64 data as intended.
+- The `list` tool's input validation is now more lenient. It will no longer error when an empty `include_window_details: []` array is provided for an `item_type` other than `application_windows`.

+# Local-Only Tests for Peekaboo
+
+This directory contains tests that can only be run locally (not on CI) because they require:
+- Screen recording permissions
+- Accessibility permissions (optional)
+- A graphical environment
+- User interaction (for permission dialogs)
+
+## Test Host Application
+
+The `TestHost` directory contains a simple SwiftUI application that serves as a controlled environment for testing screenshots and window management. The test host app:
+
+- Displays permission status
+- Shows a known window with identifiable content
+- Provides various test patterns for screenshot validation
+- Logs test interactions
+
+## Running Local Tests
+
+To run the local-only tests:
+
+```bash
+cd peekaboo-cli
+./run-local-tests.sh
+```
+
+Or manually:
+
+```bash
+# Enable local tests
+export RUN_LOCAL_TESTS=true
+
+# Run all local-only tests
+swift test --filter "localOnly"
+
+# Run specific test categories
+swift test --filter "screenshot"
+swift test --filter "permissions"
+swift test --filter "multiWindow"
+```
+
+## Test Categories
+
+### Screenshot Validation Tests (`ScreenshotValidationTests.swift`)
+- **Image content validation**: Captures windows with known content and validates the output
+- **Visual regression testing**: Compares screenshots to detect visual changes
+- **Format testing**: Tests PNG and JPG output formats
+- **Multi-display support**: Tests capturing from multiple monitors
+- **Performance benchmarks**: Measures screenshot capture performance
+
+### Local Integration Tests (`LocalOnlyTests.swift`)
+- **Test host window capture**: Captures the test host application window
+- **Full screen capture**: Tests screen capture with test host visible
+- **Permission dialog testing**: Tests permission request flows
+- **Multi-window scenarios**: Tests capturing multiple windows
+- **Focus and foreground testing**: Tests window focus behavior
+
+## Adding New Local Tests
+
+When adding new local-only tests:
+
+1. Tag them with `.localOnly` to ensure they don't run on CI
+2. Use the test host app for controlled testing scenarios
+3. Clean up any created files/windows in test cleanup
+4. Document any special requirements
+
+Example:
+```swift
+@Test("My new local test", .tags(.localOnly, .screenshot))
+func myLocalTest() async throws {
+    // Your test code here
+}
+```
+
+## Permissions
+
+The tests will automatically check for required permissions and attempt to trigger permission dialogs if needed. Grant the following permissions when prompted:
+
+1. **Screen Recording**: Required for all screenshot functionality
+2. **Accessibility**: Optional, needed for window focus operations
+
+## CI Considerations
+
+These tests are automatically skipped on CI because:
+- The `RUN_LOCAL_TESTS` environment variable is not set
+- CI environments typically lack screen recording permissions
+- There's no graphical environment for window creation
+
+The `.enabled(if:)` trait ensures these tests only run when explicitly enabled.
