Server has 11 tools with complete input schemas and descriptions, but quality is uneven. Naming follows verb_noun convention well (create_, add_, list_, remove_, update_, clear_, open_, generate_, get_, capture_). Descriptions are present but often verbose and lack actionable guidance for LLM selection. Parameters are typed with enums where appropriate (platform, language, deviceId patterns), but many lack detailed constraints or format guidance. Output schemas are not documented, critical gap for agent planning. Error handling is minimal; no recovery guidance visible. Tool composition has issues: create_app_previews conflates multiple concerns (selection, generation, capture, export); clear_all is destructive without sufficient safeguards.

• Document output schemas for all tools. For list_previews, specify: returns {previews: [{id, screenshotPath, title, subtitle, deviceId?, paletteId?, createdAt}], total: number}. For get_settings, specify: returns {defaultDeviceType, defaultPaletteId, outputDirectory, language}.
• Split create_app_previews into: generate_preview_text (takes appName, appDescription, language, screenCount → returns array of {title, subtitle}), capture_app_screenshots (takes bundleId, platform, simulatorUDID → returns array of {screenshotPath}), and export_previews_to_muse (takes previewIds, outputDirectory → returns success/failure). This enables agents to compose workflows.
• Strengthen clear_all confirmation: require the user to explicitly type 'DELETE ALL PREVIEWS' or provide a list of preview IDs to delete, not just a boolean flag. Add a dry-run mode that returns what would be deleted without executing.
• Enhance parameter descriptions with explicit constraints: screenshotPath must be an absolute path to an existing PNG/JPG file (max 50MB). deviceId must be one of: [iphone_6_9, iphone_6_7, iphone_6_5, iphone_6_3, iphone_6_1, iphone_5_5, ipad_12_9, ipad_10_9, mac_retina] (reference a list_device_types tool or enum). language must be one of: [ko, en, ja, zh, es, fr, de].
• Add error handling guidance: if screenshotPath does not exist, return 'File not found: /path/to/file. Ensure the path is absolute and the file exists.' If simulator is not running, return 'iOS Simulator not running. Start it with: xcrun simctl boot <UDID>.' This guides agent recovery.
