This provides the optimal user experience by making screenshots "just work" in most scenarios. +- 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 -- The default `capture_focus` behavior for the `image` tool has changed from "background" to "auto".
