Complete Phase 3 (P0) frontend implementation for unified MCP management:
**New Files:**
- src/hooks/useMcp.ts: React Query hooks for unified MCP operations
- src/components/mcp/UnifiedMcpPanel.tsx: Unified MCP management panel
- src/components/ui/checkbox.tsx: Checkbox component from shadcn/ui
**Features:**
- Unified panel with three-column layout: server info + app checkboxes + actions
- Multi-app control: Claude/Codex/Gemini checkboxes for each server
- Real-time stats: Show enabled server counts per app
- Full CRUD operations: Add, edit, delete, sync all servers
**Integration:**
- Replace old app-specific McpPanel with UnifiedMcpPanel in App.tsx
- Update McpFormModal to support unified mode with apps field
- Add i18n support: mcp.unifiedPanel namespace (zh/en)
**Type Safety:**
- Ensure McpServer.apps field always initialized
- Fix all test files to include apps field
- TypeScript type check passes ✅
**Architecture:**
- Single source of truth: mcp.servers manages all MCP configs
- Per-server app control: apps.claude/codex/gemini boolean flags
- Backward compatible: McpFormModal supports both unified and legacy modes
Next: P1 tasks (import dialogs, sub-components, tests)
* feat(prompts): add prompt management across Tauri service and React UI
- backend: add commands/prompt.rs, services/prompt.rs, register in commands/mod.rs and lib.rs, refine app_config.rs
- frontend: add PromptPanel, PromptFormModal, PromptListItem, MarkdownEditor, usePromptActions, integrate in App.tsx
- api: add src/lib/api/prompts.ts
- i18n: update src/i18n/locales/{en,zh}.json
- build: update package.json and pnpm-lock.yaml
* feat(i18n): improve i18n for prompts and Markdown editor
- update src/i18n/locales/{en,zh}.json keys and strings
- apply i18n in PromptFormModal, PromptPanel, and MarkdownEditor
- align prompt text with src-tauri/src/services/prompt.rs
* feat(prompts): add enable/disable toggle and simplify panel UI
- Add PromptToggle component and integrate in prompt list items
- Implement toggleEnabled with optimistic update; enable via API, disable via upsert with enabled=false;
reload after success
- Simplify PromptPanel: remove file import and current-file preview to keep CRUD flow focused
- Tweak header controls style (use mcp variant) and minor copy: rename “Prompt Management” to “Prompts”
- i18n: add disableSuccess/disableFailed messages
- Backend (Tauri): prevent duplicate backups when importing original prompt content
* style: unify code formatting with trailing commas
* feat(prompts): add Gemini filename support to PromptFormModal
Update filename mapping to use Record<AppId, string> pattern, supporting
GEMINI.md alongside CLAUDE.md and AGENTS.md.
* fix(prompts): sync enabled prompt to file when updating
When updating a prompt that is currently enabled, automatically sync
the updated content to the corresponding live file (CLAUDE.md/AGENTS.md/GEMINI.md).
This ensures the active prompt file always reflects the latest content
when editing enabled prompts.
Rename `AppType` to `AppId` across the entire frontend codebase to better
reflect its purpose as an application identifier rather than a type category.
This aligns frontend naming with backend command parameter conventions.
Changes:
- Rename type `AppType` to `AppId` in src/lib/api/types.ts
- Remove `AppType` export from src/lib/api/index.ts
- Update all component props from `appType` to `appId` (43 files)
- Update all variable names from `appType` to `appId`
- Synchronize documentation (CHANGELOG, refactoring plans)
- Update test files and MSW mocks
BREAKING CHANGE: `AppType` type is no longer exported. Use `AppId` instead.
All component props have been renamed from `appType` to `appId`.
Fix the issue where duplicated providers were being sorted to the end of the list instead of appearing directly below the original provider.
- Calculate new sortIndex as original sortIndex + 1
- Batch update sortIndex of subsequent providers to make room for the new provider
- Only perform sortIndex manipulation if the original provider has a sortIndex
- Add error handling for sortIndex update failures
- Abort duplication if sortIndex update fails to maintain consistency
The duplicated provider will now appear immediately below the original provider in the list, maintaining the expected user experience.
Add a duplicate button next to the drag handle in edit mode that allows users to quickly copy existing provider configurations.
- Add Copy icon button in ProviderCard next to drag handle
- Implement handleDuplicateProvider in App.tsx with deep cloning
- Copy all provider settings (settingsConfig, websiteUrl, category, meta)
- Auto-generate new ID and timestamp, omit sortIndex for natural sorting
- Append " copy" to duplicated provider name
- Add i18n support (zh: "复制", en: "Duplicate")
- Wire onDuplicate callback through ProviderList to ProviderCard
The duplicated provider will appear below the original provider in the list, sorted by creation time.
- Reduce header spacing (gap-4 → gap-2, gap-1.5 → gap-1) for more compact layout
- Unify provider link colors with main title (blue-500/blue-400)
- Standardize action button styles to use size="icon" for consistent hover effects
- Add proper hover backgrounds to provider action buttons matching header buttons
- Add edit mode button next to settings in header
- Edit button turns blue when active
- Drag handles fade in/out with edit mode toggle
- Add smooth 200ms transition animation
- Add i18n support for edit mode (en/zh)
- Maintain consistent spacing between header elements
Move the theme toggle from the main header to the settings dialog for a
cleaner UI and better organization. The new theme selector uses a
button group design consistent with the language settings.
Changes:
- Created ThemeSettings component with three options: Light, Dark, System
- Added ThemeSettings to the General tab in settings dialog
- Removed ModeToggle component from main header
- Added theme-related i18n keys for all options
- Theme selection takes effect immediately without requiring save
Design:
- Uses button group style matching LanguageSettings
- Icons for each theme option (Sun, Moon, Monitor)
- Consistent with app's blue theme for active state
- Smooth transitions and hover effects
This change simplifies the main header and consolidates all appearance
settings in one place, improving the overall user experience.
Fixed dual-source jitter issue:
1. Horizontal shift: Use overflow-y-scroll to force scrollbar gutter
2. Vertical jump: Use keepPreviousData to maintain content during app switch
Convert all MCP-related modal windows to use the unified shadcn/ui Dialog
component for consistency with the rest of the application.
Changes:
- McpPanel: Replace custom modal with Dialog component
- Update props from onClose to open/onOpenChange pattern
- Use DialogContent, DialogHeader, DialogTitle components
- Remove custom backdrop and close button (handled by Dialog)
- McpFormModal: Migrate form modal to Dialog
- Wrap entire form in Dialog component structure
- Use DialogFooter for action buttons
- Apply variant="mcp" to maintain green button styling
- Remove unused X icon import
- McpWizardModal: Convert wizard to Dialog
- Replace custom modal structure with Dialog components
- Use Button component with variant="mcp" for consistency
- Remove unused isLinux and X icon imports
- App.tsx: Update McpPanel usage
- Remove conditional rendering wrapper
- Pass open and onOpenChange props directly
- dialog.tsx: Fix dialog overlay and content styling
- Change overlay from bg-background/80 to bg-black/50 for consistency
- Change content from bg-background to explicit bg-white dark:bg-gray-900
- Ensures opaque backgrounds matching MCP panel style
Benefits:
- Unified dialog behavior across the application
- Consistent styling and animations
- Better accessibility with Radix UI primitives
- Reduced code duplication
- Maintains MCP-specific green color scheme
All dialogs now share the same base styling while preserving their unique
content and functionality.
Restore the vibrant color palette from the pre-refactoring version while
maintaining shadcn/ui component architecture and modern design patterns.
## Color Scheme Restoration
### Button Component
- **default variant**: Blue primary (`bg-blue-500`) - matches old `primary`
- **destructive variant**: Red (`bg-red-500`) - matches old `danger`
- **secondary variant**: Gray text (`text-gray-500`) - matches old `secondary`
- **ghost variant**: Transparent hover (`hover:bg-gray-100`) - matches old `ghost`
- **mcp variant**: Emerald green (`bg-emerald-500`) - matches old `mcp`
- Updated border-radius to `rounded-lg` for consistency
### CSS Variables
- Set `--primary` to blue (`hsl(217 91% 60%)` ≈ `bg-blue-500`)
- Added complete shadcn/ui theme variables for light/dark modes
- Maintained semantic color tokens for maintainability
### Component-Specific Colors
- **"Currently Using" badge**: Green (`bg-green-500/10 text-green-500`)
- **Delete button hover**: Red (`hover:text-red-500 hover:bg-red-100`)
- **MCP button**: Emerald green with minimum width (`min-w-[80px]`)
- **Links/URLs**: Blue (`text-blue-500`)
## Benefits
- ✅ Restored original vibrant UI (blue, green, red accents)
- ✅ Maintained shadcn/ui component system (accessibility, animations)
- ✅ Easy global theming via CSS variables
- ✅ Consistent design language across all components
- ✅ Code formatted with Prettier (shadcn/ui standards)
## Files Changed

and handle preset category metadata.
* feat: add provider usage query functionality
- Updated `Cargo.toml` to include `regex` and `rquickjs` dependencies for usage script execution.
- Implemented `query_provider_usage` command in `commands.rs` to handle usage queries.
- Created `UsageScript` and `UsageData` structs in `provider.rs` for managing usage script configurations and results.
- Added `execute_usage_script` function in `usage_script.rs` to run user-defined scripts for querying usage.
- Enhanced `ProviderList` component to include a button for configuring usage scripts and a modal for editing scripts.
- Introduced `UsageFooter` component to display usage information and status.
- Added `UsageScriptModal` for editing and testing usage scripts with preset templates.
- Updated Tauri API to support querying provider usage.
- Modified types in `types.ts` to include structures for usage scripts and results.
* feat(usage): support multi-plan usage display for providers
- 【Feature】
- Update `UsageResult` to support an array of `UsageData` for displaying multiple usage plans per provider.
- Refactor `query_provider_usage` command to parse both single `UsageData` objects (for backward compatibility) and arrays of `UsageData`.
- Enhance `usage_script` validation to accept either a single usage object or an array of usage objects.
- 【Frontend】
- Redesign `UsageFooter` to iterate and display details for all available usage plans, introducing `UsagePlanItem` for individual plan rendering.
- Improve usage display with color-coded remaining balance and clear plan information.
- Update `UsageScriptModal` test notification to summarize all returned plans.
- Remove redundant `isCurrent` prop from `UsageFooter` in `ProviderList`.
- 【Build】
- Change frontend development server port from `3000` to `3005` in `tauri.conf.json` and `vite.config.mts`.
* feat(usage): enhance query flexibility and display
- 【`src/types.ts`, `src-tauri/src/provider.rs`】Make `UsageData` fields optional and introduce `extra` and `invalidMessage` for more flexible reporting.
- `expiresAt` replaced by generic `extra` field.
- `isValid`, `remaining`, `unit` are now optional.
- Added `invalidMessage` to provide specific reasons for invalid status.
- 【`src-tauri/src/usage_script.rs`】Relax usage script result validation to accommodate optional fields in `UsageData`.
- 【`src/components/UsageFooter.tsx`】Update UI to display `extra` field and `invalidMessage`, and conditionally render `remaining` and `unit` based on availability.
- 【`src/components/UsageScriptModal.tsx`】
- Add a new `NewAPI` preset template demonstrating advanced extractor logic for complex API responses.
- Update script instructions to reflect optional fields and new variable syntax (`{{apiKey}}`).

- Remove basic syntax check for `return` statement.
- 【`.vscode/settings.json`】Add `dish-ai-commit.base.language` setting.
- 【`src-tauri/src/commands.rs`】Adjust usage logging to handle optional `remaining` and `unit` fields.
* chore(config): remove VS Code settings from version control
- delete .vscode/settings.json to remove editor-specific configurations
- add /.vscode to .gitignore to prevent tracking of local VS Code settings
- ensure personalized editor preferences are not committed to the repository
* fix(provider): preserve usage script during provider update
- When updating a provider, the `usage_script` configuration within `ProviderMeta` was not explicitly merged.
- This could lead to the accidental loss of `usage_script` settings if the incoming `provider` object in the update request did not contain this field.
- Ensure `usage_script` is cloned from the existing provider's meta when merging `ProviderMeta` during an update.
* refactor(provider): enforce base_url for usage scripts and update dev ports
- 【Backend】
- `src-tauri/src/commands.rs`: Made `ANTHROPIC_BASE_URL` a required field for Claude providers and `base_url` a required field in `config.toml` for Codex providers when extracting credentials for usage script execution. This improves error handling by explicitly failing if these critical URLs are missing or malformed.
- 【Frontend】
- `src/App.tsx`, `src/components/ProviderList.tsx`: Passed `appType` prop to `ProviderList` component to ensure `updateProvider` calls within `handleSaveUsageScript` correctly identify the application type.
- 【Config】
- `src-tauri/tauri.conf.json`, `vite.config.mts`: Updated development server ports from `3005` to `3000` to standardize local development environment.
* refactor(usage): improve usage data fetching logic
- Prevent redundant API calls by tracking last fetched parameters in `useEffect`.
- Avoid concurrent API requests by adding a guard in `fetchUsage`.
- Clear usage data and last fetch parameters when usage query is disabled.
- Add `queryProviderUsage` API declaration to `window.api` interface.
* fix(usage-script): ensure usage script updates and improve reactivity
- correctly update `usage_script` from new provider meta during updates
- replace full page reload with targeted provider data refresh after saving usage script settings
- trigger usage data fetch or clear when `usageEnabled` status changes in `UsageFooter`
- reduce logging verbosity for usage script execution in backend commands and script execution
* style(usage-footer): adjust usage plan item layout
- Decrease width of extra field column from 35% to 30%
- Increase width of usage information column from 40% to 45%
- Improve visual balance and readability of usage plan items
- Apply immediately on save (write or remove primaryApiKey)
- Honor setting on provider switch (enabled: write for non-official, remove for official; disabled: no auto writes)
- Remove per-provider Claude plugin buttons from ProviderList
- Upsert primaryApiKey=any preserving other fields; respect override dir
- Add zh/en i18n for the new setting
