YoVinchen	80c61a7fc7	fix(skill): use directory basename for skill installation path Extract last segment from skill directory path to prevent nested directory issues during install/uninstall operations. For example, "skills/codex" now correctly installs to "codex" instead of creating nested "skills/codex" path.	2025-12-05 12:33:50 +08:00
Jason	6713368657	fix(windows): use system titlebar to prevent black screen on startup The `titleBarStyle: "Overlay"` setting in tauri.conf.json causes black screen and crash on Windows due to WebView2 compatibility issues. Add platform-specific config `tauri.windows.conf.json` to override titleBarStyle to "Visible" on Windows while keeping the overlay style on macOS for the immersive UI experience. Fixes black screen issue on Windows for v3.8.x releases.	2025-12-05 11:44:54 +08:00

Replace format string placeholders with inline variable syntax for improved readability. Changes: - Convert format!("{}", var) to format!("{var}") - Apply to model_test.rs, parser.rs, and usage_stats.rs - Fix line length issues by breaking long function calls - Improve code formatting consistency All changes are automatic formatting with no functional impact. * fix(ui): restore card borders in usage statistics panels Restore proper card styling for ModelTestConfigPanel and PricingConfigPanel by adding back border and rounded-lg classes. The transparent background styling was causing visual inconsistency. Changes: - Replace border-none bg-transparent shadow-none with border rounded-lg - Apply to both loading and error states for consistency - Format TypeScript code for better readability - Break long function signatures across multiple lines This ensures the usage statistics panels have consistent visual appearance with proper borders and rounded corners. * feat(pricing): add GPT-5 Codex model pricing presets Add pricing configuration for GPT-5 Codex variants to support cost tracking for Codex-specific models. Changes: - Add gpt-5-codex model with standard GPT-5 pricing - Add gpt-5-1-codex model with standard GPT-5.1 pricing - Input: $1.25/M tokens, Output: $10/M tokens - Cache read: $0.125/M tokens, Cache creation: $0 This ensures accurate cost calculation for Codex API requests using GPT-5 Codex models.	2025-12-05 11:26:41 +08:00

farion1231	74a2e9c08b	fix(mcp): use browser-compatible platform detection for MCP presets Replace Node.js process.platform check with navigator.userAgent-based detection from @/lib/platform. The previous implementation using process.platform failed in Tauri's browser environment, causing Windows platform to always return false and not apply the required 'cmd /c' wrapper for npx commands. This fix ensures that on Windows, MCP presets like sequential-thinking correctly use 'cmd /c npx' format instead of direct 'npx', eliminating the warning: "Windows requires 'cmd /c' wrapper to execute npx" Changes: - Import isWindows() from @/lib/platform instead of defining locally - Remove incorrect process.platform-based detection - Now properly detects Windows in browser/WebView environment	2025-12-02 15:43:14 +08:00
