feat: Add script to automate Homebrew tap updates

- Add Info.plist with bundle identifier and usage descriptions
- Embed Info.plist into binary using linker flags in Package.swift
- Add Developer ID code signing to build script (with ad-hoc fallback)
- Update version to 2.0.0 in Info.plist
- Enable runtime hardening for notarization readiness

This ensures Peekaboo works properly with macOS permissions system and can be distributed via Homebrew with proper code signing.

-## [1.1.0] - 2025-06-10
-
-### Added
-- **PID-based application targeting**: Target applications by their Process ID using the `PID:XXXX` syntax
-  - Works with both `image` and `list` tools
-  - Example: `app_target: "PID:663"` to capture windows from process 663
-  - Provides clear error messages for invalid PIDs or non-existent processes
-  - Useful for targeting specific instances when multiple copies of an app are running
-
-- **Enhanced AI Provider Status Checking**: Server status now includes comprehensive AI provider diagnostics
-  - Real-time validation of OpenAI API keys and model availability
-  - Ollama server connectivity and model installation status
-  - Specific troubleshooting guidance for each provider type
-  - Network timeout detection and error reporting
-  - Detailed error messages with actionable next steps
-
-### Fixed
-- **Window Bounds Display**: Fixed window bounds showing as `[undefined,undefined WIDTH×HEIGHT]` by simplifying field names from `x_coordinate`/`y_coordinate` to `x`/`y` throughout the codebase
-- **Image Quality**: Added JPEG compression quality setting (0.95) to maintain high quality while reducing file sizes for AI analysis
-- **Long Filename Handling**: Fixed critical edge case where very long filenames combined with Peekaboo's metadata could exceed the 255-byte macOS filesystem limit
-  - Implemented UTF-8 aware truncation algorithm that safely handles multibyte characters (emoji, non-Latin scripts)
-  - Truncation occurs at valid UTF-8 boundaries to prevent corrupted characters
-  - Ensures metadata suffixes are always preserved when capturing multiple items
-  - Added comprehensive test suite covering edge cases including exactly 255-byte filenames
-- **Semicolon Separator Support**: AI provider configuration now supports both comma (`,`) and semicolon (`;`) separators
-  - Example: `"openai/gpt-4o;ollama/llava:latest"` now works correctly
-  - Fixes configuration parsing issues with Claude Desktop configurations that use semicolons
-
-### Changed
-- **Code Simplification**: Removed unnecessary CodingKeys mapping in WindowBounds struct, simplifying JSON serialization
-- **Smart Path Handling**: Completely redesigned how output paths are handled based on capture context:
-  - **Single Capture Behavior**: When capturing exactly one item (one window, one screen on a single-display system, or frontmost window), the specified path is used exactly as provided
-    - Examples: `path: "~/Desktop/shot.png"` → saves to `~/Desktop/shot.png`
-  - **Multiple Capture Behavior**: When capturing multiple items (multiple windows, multiple screens, or using `mode: "multi"`), metadata is automatically appended to prevent file overwrites
-    - Window example: `path: "~/Desktop/shot.png"` → `~/Desktop/shot_Safari_window_0_20250610_120000.png`
-    - Screen example: `path: "~/Desktop/shot.png"` → `~/Desktop/shot_1_20250610_120000.png`
-  - **Directory Path Behavior**: Paths identified as directories (ending with `/` or no extension) always use generated filenames
-    - Example: `path: "~/Desktop/screenshots/"` → `~/Desktop/screenshots/Safari_20250610_120000.png`
-- **Default AI Provider Configuration**: README now shows OpenAI GPT as primary with Ollama as fallback in installation examples
-
-### Improved
-- **Invalid Format Handling**: Enhanced format validation with user-friendly feedback
-  - Invalid formats ("bmp", "gif", "tiff", etc.) are automatically converted to PNG
-  - Clear warning message included in response: `"Invalid format 'bmp' was provided. Automatically using PNG format instead."`
-  - Format validation happens early in the request processing pipeline
-- **Faster AI Provider Checks**: Reduced timeout from 5 seconds to 3 seconds for quicker status responses
-- **Better Error Diagnostics**: Provider status checks now distinguish between API key issues, network problems, and missing models

-  - Fixed issue where unexpected errors would cause "No result received" response
-  - All tool execution errors now return proper MCP error responses
-  - Handles edge cases with special characters in tool parameters gracefully
-  - Prevents server from silently failing on unexpected exceptions
-
-## [1.0.0-beta.24] - 2025-01-08
-
-### Changed
-- **Complete Swift 6 migration with strict concurrency**
-  - Migrated to Swift 6.0 toolchain with StrictConcurrency enabled
-  - All data models and types now conform to Sendable protocol
-  - Replaced AsyncParsableCommand with ParsableCommand + async adapter pattern
-  - Implemented proper async/sync bridging using DispatchSemaphore for ArgumentParser compatibility
-  - Fixed CLI execution issue where commands were showing help instead of executing
-
-### Improved
-- Enhanced thread safety with @unchecked Sendable for synchronized state

-- More robust error handling in async contexts
-
-## [1.0.0-beta.23] - 2025-01-08
-
-### Changed
-- Initial Swift 6 migration attempt (had execution issues, fixed in beta.24)
-
-## [1.0.0-beta.22] - 2025-01-08
-
-### Fixed
-- **Critical deadlock fix in Swift CLI image capture**
-  - Removed DispatchSemaphore usage that violated Swift concurrency rules and caused infinite hangs
-  - Implemented RunLoop-based async-to-sync bridging for proper concurrency handling
-  - Converted all capture methods to async/await patterns while maintaining CLI compatibility
-  - Replaced Thread.sleep with Task.sleep in async contexts
-  - Fixed test timeouts by eliminating blocking operations
-  - No macOS version requirements added - solution uses standard Foundation APIs
-
-### Added
-- **Smart browser helper filtering for improved Chrome/Safari matching**
-  - Automatically filters out browser helper processes when searching for common browsers (chrome, safari, firefox, edge, brave, arc, opera)
-  - Prevents confusing "no capturable windows" errors when helper processes like "Google Chrome Helper (Renderer)" are matched instead of the main browser
-  - Provides browser-specific error messages: "Chrome browser is not running or not found" instead of generic app not found errors
-  - Only applies filtering to browser identifiers - other application searches work normally
-  - Comprehensive test coverage for browser filtering scenarios
-
-- **Proper frontmost window capture implementation**
-  - Added dedicated `frontmost` capture mode that captures the frontmost window of the frontmost application
-  - Replaces previous fallback behavior that incorrectly captured all screens
-  - Uses `NSWorkspace.shared.frontmostApplication` to detect the currently active application
-  - Returns exactly one image with proper metadata (app name, window title, window ID)
-  - Generates descriptive filenames like `frontmost_Safari_20250608_083230.png`
-
-### Fixed
-- **List tool empty string parameter handling**
-  - Fixed issue where `item_type: ""` was not properly defaulting to the correct operation
-  - Empty strings and whitespace-only strings now fall back to proper default logic
-  - Added comprehensive test coverage for edge cases
-
-## [1.0.0-beta.21] - 2025-06-08
-
-### Security
-- **Critical security fix for malformed app targets**
-  - Fixed vulnerability where malformed app targets with multiple leading colons (e.g., "::::::::::::::::Finder") created empty app names that would match ALL system processes
-  - Enhanced input validation to prevent unintended broad process matching
-  - Added defensive parsing logic with fallback to screen mode for invalid inputs
-  - Comprehensive test coverage for edge cases and malformed inputs
-
-### Changed
-- **Multiple exact app matches now capture all windows instead of erroring**
-  - When multiple applications have exact matches (e.g., "claude" and "Claude"), the system now captures all windows from all matching applications
-  - This replaces the previous behavior of throwing an ambiguous match error
-  - Window indices are sequential across all matched applications
-  - Each saved file preserves the original application name in `item_label`
-  - Only truly ambiguous fuzzy matches still return errors
-  - Comprehensive test coverage for various multiple match scenarios
-
-### Fixed
-- **Enhanced error handling and user experience**
-  - Improved window title matching error messages with available window titles and URL guidance
-  - Fixed path traversal error reporting to show correct file system errors instead of permission errors
-  - Added case-insensitive handling for window specifiers (WINDOW_TITLE, window_title, etc.)
-  - Enhanced backward compatibility with hidden path parameters in analyze tool
-- **Format validation improvements**
-  - Added defensive format validation with automatic PNG fallback for invalid formats
-  - Improved file extension correction when format is changed
-  - Better handling of edge cases in image processing
-
-## [1.0.0-beta.20] - 2025-06-08
-
-### Added
-- **Window count display optimization**: Single-window apps no longer show "Windows: 1" in list output ([#6](https://github.com/steipete/Peekaboo/pull/6))
-  - Reduces visual clutter for the common case of apps with only one window
-  - Apps with 0, 2, or more windows still display the count
-  - Improves readability of the `list apps` command output
-- **Timeout handling for Swift CLI operations** ([#2](https://github.com/steipete/Peekaboo/pull/2))
-  - Prevents test suite and operations from hanging indefinitely
-  - Default timeout of 30 seconds, configurable via `PEEKABOO_CLI_TIMEOUT` environment variable
-  - Graceful process termination with SIGTERM followed by SIGKILL if needed
-  - Clear timeout error messages indicating when operations exceed time limits
-
-### Fixed
-- **Input validation improvements**:
-  - Whitespace is now trimmed from `app_target` parameter (e.g., `"   Spotify   "` now works correctly)
-  - Format parameter is now case-insensitive (`"PNG"` and `"png"` both work)
-  - Added support for `"jpeg"` as an alias for `"jpg"` format
-- **Edge case handling**:
-  - Float and hex screen indices now parse correctly (e.g., `screen:1.5` → `screen:1`, `screen:0x1` → `screen:0`)
-  - Special filesystem characters (|, :, *) in filenames are preserved as-is
-  - Empty questions to analyze tool are handled gracefully (analysis is skipped)
-- **Swift error handling improvements**:
-  - Fixed CaptureError enum compatibility issues in tests
-  - Improved error messages with better context for ApplicationFinder errors
-- Fixed overly broad permission error detection that incorrectly reported file I/O errors as screen recording permission issues
-  - File permission errors (e.g., writing to `/System/`) now correctly report as `FILE_IO_ERROR`
-  - Directory not found errors provide clear messages about missing parent directories
-  - Added specific error code checking for ScreenCaptureKit and CoreGraphics APIs
-  - Only errors containing both "permission" and capture-related terms are now considered screen recording issues
-- Enhanced file write error handling with pre-emptive directory checks
-- Added debug logging to permission checker for diagnosing intermittent failures
-- Improved error propagation from deep system APIs
-  - Underlying errors from ScreenCaptureKit and file operations are now captured and logged
-  - Debug logs include full error details for better troubleshooting
-  - Error messages include the original system error descriptions
-- Fixed duplicate error output when ApplicationFinder throws errors
-- Enhanced error details for app not found errors to include list of available applications
-- Removed complex multi-JSON parsing logic from TypeScript that was only needed due to duplicate error output
-- Fixed all test assertions to match the new `executeSwiftCli` signature with timeout parameter
-
-## [1.0.0-beta.19] - 2025-06-08
-
-### Added
-- Automatic format fallback for screen captures to prevent JavaScript stack overflow errors
-  - When `format: "data"` is specified for screen captures, the tool automatically falls back to PNG format
-  - A warning message is included in the response explaining why the fallback occurred
-  - Application window captures can still use `format: "data"` without restrictions
-  - This prevents agents from encountering "Maximum call stack size exceeded" errors when capturing screens
-- Invalid format values now automatically fall back to PNG instead of returning an error
-  - Empty strings, null values, and unrecognized format values are converted to PNG
-  - This provides a better user experience by gracefully handling invalid inputs
-- Enhanced error messages for ambiguous application identifiers
-  - When multiple applications match an identifier (e.g., "C" matches Calendar, Console, and Cursor), the error message now lists all matching applications with their bundle IDs
-  - This helps users quickly identify the correct application name to use
-  - Applies to both `image` and `list` tools
-
-## [1.0.0-beta.18] - 2025-06-08
-
-### Added
-- Fuzzy matching for application names using Levenshtein distance algorithm
-  - Typos like "Chromee" now correctly match "Google Chrome"
-  - Common misspellings are handled intelligently (e.g., "Finderr" → "Finder")
-  - Multi-word app names are matched word-by-word for better accuracy
-- Smart error messages that suggest similar app names when no exact match is found
-- Window-specific labels in analysis results when capturing multiple windows
-  - Shows window titles instead of repeating app names
-  - Example: 'Analysis for "MCP Inspector":' instead of "Analysis for Google Chrome"
-
-### Fixed
-- Error messages now show specific details instead of generic "unknown error"
-  - Non-existent apps show: "No running applications found matching identifier: AppName"
-  - Properly parses Swift CLI JSON error responses
-- Fixed test failures related to error message format changes
-
-### Changed
-- Improved application matching scoring to prefer main apps over helper processes
-- Enhanced TypeScript error handling to parse JSON responses even on non-zero exit codes
-
-## [1.0.0-beta.21] - 2025-01-10
-
-### Fixed
-- The `list` tool no longer returns a generic "unknown error" when a non-existent `app` is specified. It now returns a clear error message: `"List operation failed: The specified application ('AppName') is not running or could not be found."`, improving usability and error diagnosis.
-
-## [1.0.0-beta.20] - 2025-01-09
-
-### Changed
-- Improved error message for the `image` tool. When an `app_target` is specified for a running application that has no visible windows, the tool now returns a specific error (`"Image capture failed: The 'AppName' process is running, but it has no capturable windows..."`) instead of a generic "window not found" error. This provides clearer feedback and suggests using `capture_focus: 'foreground'` as a remedy.
-
-## [1.0.0-beta.19] - 2025-01-08
-
-### Changed
-- The `image` tool's behavior has been updated. When a `question` is provided for analysis and no `path` is specified, the tool now preserves the captured image(s) in their temporary directory instead of deleting them. The paths to these saved files are now correctly returned in the `saved_files` array, making them accessible after the tool run completes.
-
-## [1.0.0-beta.18] - 2025-01-08
-
-### Fixed
-- Fixed a bug where providing an empty string for the `capture_focus` parameter in the `image` tool would cause a validation error. The schema now correctly handles this case and applies the default value ('background'), making the parameter truly optional.
-
-## [1.0.0-beta.17] - 2025-01-08
-
-### Added
-- The `image` tool's analysis capability has been significantly enhanced. When a capture results in multiple images (e.g., targeting an application with multiple windows) and a `question` is provided, the tool will now perform an AI analysis for **every single captured image**.
-- The analysis results are returned in a single, clearly formatted text block, with each window's analysis presented under a descriptive header.
-
-## [1.0.0-beta.16] - 2025-01-08
-
-### Enhanced
-- **Smart Path Handling**: The Swift CLI now intelligently detects whether a provided path is intended as a file or directory:
-  - **File paths** (with extensions): Uses exact path for single screen captures, appends screen identifiers for multiple captures
-  - **Directory paths** (no extension or trailing `/`): Places generated filenames inside the directory
-  - **Auto-Creation**: Automatically creates intermediate directories as needed for both file and directory paths
-  - **Edge Cases**: Properly handles special directory indicators (`.`, `..`), hidden files, unicode characters, and paths with spaces
-
-### Improved
-- **Enhanced Error Messages**: File write errors now provide detailed, actionable guidance:
-  - Permission denied errors include specific directory permission checks
-  - Missing directory errors suggest ensuring parent directories exist  
-  - Disk space errors clearly indicate insufficient storage
-  - Generic I/O errors include underlying system error details
-
-### Added
-- **Comprehensive Test Coverage**: Added 52+ new tests covering path handling, error scenarios, and edge cases
-- **Path Logic Validation**: Tests for file vs directory detection, multiple format support, and special character handling
-
-### Fixed
-- Fixed original issue where `/tmp/screenshot.png` was incorrectly treated as a directory instead of a filename
-- Improved file extension preservation when appending screen/window identifiers to filenames
-- Enhanced path validation for complex nested directory structures
-
-## [1.0.0-beta.15] - 2025-01-08
-
-### Improved
-- The `list` tool is now more lenient. `item_type` is optional and defaults to `running_applications`. If an `app` is specified without an `item_type`, it intelligently defaults to `application_windows`.
-
-### Fixed
-- Fixed a bug where the `list` tool would crash if called with an empty `item_type`.
-- Fixed a bug where the `image` tool would fail silently if no path was provided, resulting in a generic "Failed to write file" error. The logic for handling temporary paths is now more robust.
-
-## [1.0.0-beta.14] - 2025-01-08
-
-### Added
-- Enhanced test host application with real-time permission status display and CLI availability checking
-- Comprehensive test coverage improvements with proper Swift Testing patterns
-- Local test execution framework with detailed setup instructions
-
-### Improved
-- Swift code quality: Fixed all SwiftLint violations (reduced from 31 to 0 serious violations)
-- Test stability: Resolved Swift test compilation errors and improved test reliability
-- Code organization: Refactored ImageCommand.swift for better readability and maintainability
-- Documentation: Enhanced CLAUDE.md and release documentation with proper testing procedures
-
-### Fixed
-- JSON encoding/decoding issues in tests by removing unnecessary snake_case conversions
-- Window title validation expectations for system windows without titles
-- Swift Testing syntax errors and compiler warnings
-- Function and file length violations through strategic refactoring
-
-## [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`.
-
-## [1.0.0-beta.12] - 2025-01-08
-
-### Added
-- Comprehensive Swift Testing framework adoption with enhanced test coverage
-- New test files for JSON output validation, logger thread safety, and image capture logic
-- Centralized test tagging system for better test organization
-
-### Improved
-- CI/CD pipeline now uses macOS-15 runner with Xcode 16.3
-- Swift CLI is now built before TypeScript tests to fix integration test failures
-- Applied SwiftFormat to all Swift files for consistent code style
-- Fixed all SwiftLint violations (31 issues resolved) achieving zero linting issues
-- Enhanced thread safety in Logger implementation
-- Optimized tests with parameterized testing and async/await patterns
-
-### Fixed
-- Fixed a bug where calling the `image` tool without a `path` argument would incorrectly result in a "Failed to write to file" error. The tool now correctly captures the image to a temporary location and returns the image data as Base64, as intended by the specification.
-- Fixed Swift test compilation errors with proper Swift Testing syntax
-- Fixed TypeScript test expectations after error message improvements
-- Resolved CI integration test failures by ensuring Swift CLI availability
-
-## [1.0.0-beta.11] - 2025-01-06
-
-### Improved
-- Greatly enhanced error handling for the `image` tool. The Swift CLI now returns distinct exit codes for different error conditions, such as missing Screen Recording or Accessibility permissions, instead of a generic failure code.
-- The Node.js server now maps these specific exit codes to clear, user-friendly error messages, guiding the user on how to resolve the issue (e.g., "Screen Recording permission is not granted. Please enable it in System Settings...").
-- This replaces the previous generic "Swift CLI execution failed" error, providing a much better user experience, especially during initial setup and permission granting.
-
-## [1.0.0-beta.10] - 2024-07-28
-
-### 🎉 Major Improvements
-- **Full MCP Best Practices Compliance**: Implemented all requirements from the MCP best practices guide
-- **Enhanced Info Command**: The `server_status` option in the list tool now provides comprehensive diagnostics including:
-  - Native binary (Swift CLI) status and version
-  - System permissions (screen recording, accessibility)
-  - Environment configuration and potential issues
-  - Log file accessibility checks
-- **Dynamic Version Injection**: Swift CLI version is now automatically synchronized with package.json during build
-- **Improved Code Quality**: 
-  - Split large image.ts (472 lines) into smaller, focused modules (<250 lines each)
-  - Added ESLint configuration with TypeScript support
-  - Fixed all critical linting errors and reduced warnings
-  - Improved TypeScript types throughout the codebase
-
-### 🔧 Changed
-- Default log path updated to `~/Library/Logs/peekaboo-mcp.log` (macOS standard location)
-- Updated macOS requirement to v14+ (Sonoma) for better compatibility
-- Pino logger now falls back to temp directory if configured path is not writable
-- LICENSE and README.md now included in npm package
-
-### 🐛 Fixed
-- Swift CLI version synchronization with npm package
-- ESLint errors for unused variables and improper types
-- Test setup converted from Jest to Vitest syntax
-- All trailing spaces and formatting issues
-
-### 📦 Development
-- Added Swift compiler warning checks in release preparation
-- Enhanced prepare-release script with comprehensive validation
-- Added `npm run inspector` for MCP inspector tool
-
-## [1.0.0-beta.9] - 2025-01-25
-
-### 🔧 Changed
-- Updated server status formatting to improve readability
-
-## [1.0.0-beta.3] - 2025-01-21
-
-### Added
-- Enhanced `image` tool to support optional immediate analysis of the captured screenshot by providing a `question` and `provider_config`.
-  - If a `question` is given and no `path` is specified, the image is saved to a temporary location and deleted after analysis.
-  - If a `question` is given, Base64 image data is not returned in the `content` array; the analysis result becomes the primary payload, alongside image metadata.
-
-### Changed
-- Migrated test runner from Jest to Vitest.
-- Updated documentation (`README.md`, `docs/spec.md`) to reflect new `image` tool capabilities.
-
-## [1.0.0-beta.2] - Previous Release Date

-- MCP `image` tool: Now fully supports `app_target: "screen:INDEX"` by utilizing the Swift CLI's new `--screen-index` capability
-
-### ♻️ Changed
-
-- **MCP `image` tool API significantly simplified:**
-    - Replaced `app`, `mode`, and `window_specifier` parameters with a single `app_target` string (e.g., `"AppName"`, `"AppName:WINDOW_TITLE:Title"`, `"screen:0"`).
-    - `format` parameter now includes `"data"` option to return Base64 PNG data directly. If `path` is also given with `format: "data"`, file is saved (as PNG) AND data is returned.
-    - If `path` is omitted, `image` tool now defaults to `format: "data"` behavior (returns Base64 PNG data).

+# Setting Up Homebrew Tap for Peekaboo
+
+This guide explains how to set up and maintain the Homebrew tap for Peekaboo distribution.
+
+## Repository Structure
+
+The Homebrew tap is hosted at [github.com/steipete/homebrew-tap](https://github.com/steipete/homebrew-tap).
+
+### Key Files
+
+- **Formula/peekaboo.rb**: The Homebrew formula that defines how to install Peekaboo
+- **.github/workflows/update-formula.yml**: GitHub Action to update the formula when new releases are published
+- **README.md**: User-facing documentation for the tap
+
+## Initial Setup (Already Complete)
+
+The tap repository has been created and initialized with:
+- Initial formula at `Formula/peekaboo.rb`
+- GitHub Action workflow for automated updates
+- README with installation instructions
+
+### Setting Up GitHub Token
+
+For automated updates from the main repository:
+
+1. Go to https://github.com/settings/tokens/new
+2. Create a token with `repo` scope
+3. Name it `HOMEBREW_TAP_TOKEN`
+4. Add to main repo secrets: Settings → Secrets → Actions → New repository secret
+
+## Usage
+
+### Installing Peekaboo via Homebrew
+
+Users can now install Peekaboo with:
+
+```bash
+brew tap steipete/tap
+brew install peekaboo
+```
+
+### Updating Peekaboo
+
+```bash
+brew update
+brew upgrade peekaboo
+```
+
+## Release Process
+
+### Automated (Recommended)
+
+When you create a GitHub release, the workflow automatically:
+1. Downloads the release artifact
+2. Calculates SHA256
+3. Updates the formula in both repos
+4. Creates a PR in the main repo
+
+### Manual Update
+
+If needed, update the formula manually:
+
+```bash
+# After building release artifacts
+./scripts/release-binaries.sh
+
+# Get the SHA256
+shasum -a 256 release/peekaboo-macos-universal.tar.gz
+
+# Update formula
+./scripts/update-homebrew-formula.sh 2.0.1 <sha256>
+
+# Push to tap
+cd /path/to/homebrew-tap
+git pull
+cp /path/to/peekaboo/homebrew/peekaboo.rb Formula/
+git add Formula/peekaboo.rb
+git commit -m "Update to v2.0.1"
+git push
+```
+
+## Testing
+
+### Test Installation
+
+```bash
+# Test from your tap
+brew tap steipete/peekaboo
+brew install --verbose --debug peekaboo
+brew test peekaboo
+```
+
+### Test Formula Locally
+
+```bash
+# Direct install from formula file
+brew install --build-from-source ./homebrew/peekaboo.rb
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **SHA256 Mismatch**
+   - Ensure you're using the final release artifact
+   - Use `shasum -a 256` on macOS
+
+2. **Download Failures**
+   - Check the URL is correct
+   - Ensure the release is published (not draft)
+
+3. **Permission Errors**
+   - The formula includes post_install to ensure executable permissions
+
+### Debugging
+
+```bash
+# Verbose installation
+brew install --verbose --debug peekaboo
+
+# Check tap
+brew tap-info steipete/peekaboo
+
+# Audit formula
+brew audit --strict steipete/peekaboo/peekaboo
+```
+
+## Maintenance
+
+### Updating Dependencies
+
+If macOS requirements change:
+```ruby
+depends_on macos: :ventura  # For macOS 13+
+```
+
+### Adding Cask (Future)
+
+For a full GUI app distribution:
+```ruby
+cask "peekaboo" do
+  version "2.0.0"
+  sha256 "..."
+  
+  url "https://github.com/steipete/peekaboo/releases/download/v#{version}/Peekaboo.app.zip"
+  name "Peekaboo"
+  desc "Screenshot and AI analysis tool"
+  homepage "https://github.com/steipete/peekaboo"
+  
+  app "Peekaboo.app"
+end
+```
+
+## Best Practices
+
+1. **Version Tags**: Always use `v` prefix (e.g., `v2.0.0`)
+2. **Testing**: Test formula locally before pushing
+3. **Checksums**: Always verify SHA256 after building
+4. **Release Notes**: Update formula caveats for major changes
+5. **Compatibility**: Test on both Intel and Apple Silicon

+```
+
+## Initial Setup
+
+### 1. Create Homebrew Tap Repository
+
+```bash
+# Create new repository on GitHub named: homebrew-tap
+# Then clone and set up:
+git clone git@github.com:steipete/homebrew-tap.git
+cd homebrew-tap
+mkdir Formula
+cp /path/to/peekaboo/homebrew/peekaboo.rb Formula/
+git add .
+git commit -m "Initial formula for Peekaboo"
+git push
+```
+
+### 2. Configure GitHub Secrets
+
+For automated Homebrew updates:
+1. Create a GitHub Personal Access Token at https://github.com/settings/tokens/new
+   - Scopes needed: `repo` (for creating PRs in tap repository)
+2. Add as `HOMEBREW_TAP_TOKEN` in main repository secrets
+
+For npm publishing:
+1. Get npm access token: `npm login` then `cat ~/.npmrc`
+2. Add as `NPM_TOKEN` in repository secrets
+
+## Release Process
+
+### 1. Prepare Release
+
+```bash
+# Update version in package.json
+npm version minor  # or major/patch
+
+# Update CHANGELOG.md with release notes
+# Include:
+# - New features
+# - Bug fixes
+# - Breaking changes
+# - Contributors
+
+# Commit changes
+git add package.json package-lock.json CHANGELOG.md
+git commit -m "Release v2.0.1"
+```
+
+### 2. Run Pre-Release Checks
+
+```bash
+# Test the release process without publishing
+./scripts/release-binaries.sh --dry-run
+
+# Or run checks manually:
+npm test
+npm run lint:swift
+npm run build:all
+```
+
+### 3. Create Release
+
+```bash
+# Tag the release
+git tag v2.0.1
+git push origin main --tags
+
+# Create full release with all channels
+./scripts/release-binaries.sh --create-github-release --publish-npm
+
+# Or selectively:
+./scripts/release-binaries.sh --create-github-release  # GitHub only
+./scripts/release-binaries.sh --publish-npm            # npm only
+./scripts/release-binaries.sh                          # Local artifacts only
+```
+
+### 4. Verify Release
+
+1. **GitHub Release**: Check https://github.com/steipete/peekaboo/releases
+2. **npm Package**: Verify with `npm view @steipete/peekaboo-mcp`
+3. **Homebrew Formula**: PR should be created in tap repository
+4. **Test Installation**:
+   ```bash
+   # Homebrew
+   brew tap steipete/tap
+   brew install peekaboo
+   
+   # npm
+   npm install -g @steipete/peekaboo-mcp
+   ```
+
+## Release Artifacts
+
+Each release creates:
+
+1. **Universal Binary Tarball**
+   - `peekaboo-v{VERSION}-darwin-universal.tar.gz`
+   - Contains pre-built Swift CLI binary
+   - Supports both Apple Silicon and Intel Macs
+
+2. **npm Package**
+   - `peekaboo-mcp-{VERSION}.tgz`
+   - Includes TypeScript server and bundled Swift binary
+   - Ready for `npm publish`
+
+3. **Checksums**
+   - Individual `.sha256` files for each artifact
+   - Combined `checksums.txt` for all artifacts
+
+## Version Management
+
+- Version is centrally managed in `package.json`
+- Swift CLI reads version from package.json during build
+- All release scripts validate version consistency
+- Follow semantic versioning (MAJOR.MINOR.PATCH)
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Version Mismatch**
+   ```bash
+   # Ensure git tag matches package.json
+   git tag -d v2.0.1  # Delete local tag
+   git push origin :refs/tags/v2.0.1  # Delete remote tag
+   npm version 2.0.1 --no-git-tag-version  # Fix version
+   git add . && git commit -m "Fix version"
+   git tag v2.0.1
+   ```
+
+2. **Build Failures**
+   ```bash
+   # Clean and rebuild
+   npm run clean
+   npm run build:all
+   
+   # Check Swift toolchain
+   swift --version  # Should be 5.9+
+   ```
+
+3. **Formula Update Failed**
+   - Check HOMEBREW_TAP_TOKEN is set correctly
+   - Ensure token has repo scope
+   - Manually update: `./scripts/update-homebrew-formula.sh v2.0.1`
+
+## Manual Homebrew Formula Update
+
+If automated update fails:
+
+```bash
+# Update formula manually
+./scripts/update-homebrew-formula.sh v2.0.1
+
+# Copy to tap repository
+cp homebrew/peekaboo.rb ../homebrew-tap/Formula/
+
+# Create PR manually
+cd ../homebrew-tap
+git checkout -b update-v2.0.1
+git add Formula/peekaboo.rb
+git commit -m "Update Peekaboo to v2.0.1"
+git push origin update-v2.0.1
+# Create PR on GitHub
+```
+
+## Testing Releases
+
+### Local Testing
+
+```bash
+# Test binary directly
+./release/peekaboo-v2.0.1-darwin-universal/peekaboo --version
+
+# Test npm package
+npm pack  # Creates .tgz
+npm install -g peekaboo-mcp-2.0.1.tgz
+peekaboo-mcp --version
+```
+
+### Integration Testing
+
+```bash
+# Test with MCP Inspector
+npx @modelcontextprotocol/inspector npx @steipete/peekaboo-mcp@latest
+
+# Test specific version
+npx @modelcontextprotocol/inspector npx @steipete/peekaboo-mcp@2.0.1
+```
+

+              Peekaboo requires system permissions to function properly:
+              
+              ✅ Screen Recording (REQUIRED)
+                 Needed for all screenshot operations
+                 Grant via: System Settings > Privacy & Security > Screen Recording
+              
+              ⚠️  Accessibility (OPTIONAL)
+                 Needed for window focus control (foreground capture mode)
+                 Grant via: System Settings > Privacy & Security > Accessibility
+              
+              Check your permissions status:
+                peekaboo permissions                    # Human-readable output
+                peekaboo permissions --json-output      # Machine-readable JSON
+
+            CONFIGURATION:
+              Peekaboo uses a configuration file at ~/.config/peekaboo/config.json
+              
+              peekaboo config init        # Create default configuration file
+              peekaboo config edit        # Open config in your editor
+              peekaboo config show        # Display current configuration
+              peekaboo config validate    # Check configuration syntax
+              
+              The config file uses JSONC format (JSON with Comments) and supports:
+              • Comments using // and /* */
+              • Environment variable expansion with ${VAR_NAME}
+              • Hierarchical settings for AI providers, defaults, and logging
