Merge macOS Alacritty/Kitty/Ghostty launchers into a single generic
`launch_macos_open_app` function with a `use_e_flag` parameter.
Replace Windows cmd/PowerShell/wt launchers with a shared
`run_windows_start_command` helper. Reduces ~98 lines of duplicate code.
Use /K instead of /C flag to prevent cmd window from closing
immediately after batch file execution. Also remove the buggy
errorlevel check that was checking del command's return value
instead of claude's.
Fixes#726
Previously, enabling auto failover kept using the current provider until
the first failure, causing inconsistency when the current provider was
not in the failover queue. When stopping proxy, the restored config
would not match user expectations.
New behavior:
- Enable auto failover = immediately switch to queue P1
- Subsequent routing follows queue order (P1→P2→...)
- Auto-add current provider to queue if queue is empty
Changes:
- Add switch_proxy_target() for hot-switching during proxy mode
- Update provider_router to use queue order when failover enabled
- Sync tray menu Auto click with the same logic
- Update UI tooltips to reflect new semantics
- Add tests for queue-only routing scenario
- Format Rust code with rustfmt (misc.rs, types.rs)
- Format TypeScript/React code with Prettier (4 files)
- Fix ProviderList test by wrapping with QueryClientProvider
* refactor(ui): simplify UpdateBadge to minimal dot indicator
* feat(provider): add individual test and proxy config for providers
Add support for provider-specific model test and proxy configurations:
- Add ProviderTestConfig and ProviderProxyConfig types in Rust and TypeScript
- Create ProviderAdvancedConfig component with collapsible panels
- Update stream_check service to merge provider config with global config
- Proxy config UI follows global proxy style (single URL input)
Provider-level configs stored in meta field, no database schema changes needed.
* feat(ui): add failover toggle and improve proxy controls
- Add FailoverToggle component with slide animation
- Simplify ProxyToggle style to match FailoverToggle
- Add usage statistics button when proxy is active
- Fix i18n parameter passing for failover messages
- Add missing failover translation keys (inQueue, addQueue, priority)
- Replace AboutSection icon with app logo
* fix(proxy): support system proxy fallback and provider-level proxy config
- Remove no_proxy() calls in http_client.rs to allow system proxy fallback
- Add get_for_provider() to build HTTP client with provider-specific proxy
- Update forwarder.rs and stream_check.rs to use provider proxy config
- Fix EditProviderDialog.tsx to include provider.meta in useMemo deps
- Add useEffect in ProviderAdvancedConfig.tsx to sync expand state

with byte size, matching the existing response logging format.
* fix(log): prevent usize underflow in KeepSome rotation strategy
KeepSome(n) internally computes n-2, so n=1 causes underflow.
Use KeepSome(2) as the minimum safe value.
- Create separate removeFromLiveConfig API for additive mode apps
(remove only removes from live config, not database)
- Fix useSwitchProviderMutation to invalidate opencodeLiveProviderIds
cache so button state updates correctly after add operation
- Show appropriate toast messages:
- Add: "已添加到配置" / "Added to config"
- Remove: "已从配置移除" / "Removed from config"
- Add i18n texts for addToConfigSuccess and removeFromConfigSuccess
Add missing OpenCode branch in parse_app_type() and include OpenCode
in all app iteration loops for skills operations (uninstall, scan,
import, migrate).
OpenCode uses additive provider management where providers can exist in
the database but not necessarily in the live opencode.json config. This
commit implements proper isInConfig state:
Backend:
- Add get_opencode_live_provider_ids command to query live config
Frontend:
- Add getOpenCodeLiveProviderIds API method
- ProviderList queries live provider IDs and computes isInConfig
- ProviderCard receives and passes isInConfig to ProviderActions
- ProviderActions already handles the add/remove button logic
- Add import_opencode_providers_from_live command to provider.rs
- Register new command in lib.rs invoke_handler
- Update commands/mcp.rs: include OpenCode in sync_other_side logic
- Add McpService::import_from_opencode to import_mcp_from_apps
- Implement MCP sync/remove for OpenCode in services/mcp.rs
- sync_server_to_app_no_config now calls sync_single_server_to_opencode
- remove_server_from_app now calls remove_server_from_opencode
Add OpenCode as the 4th supported application with additive provider management:
- Add OpenCode variant to AppType enum with all related match statements
- Add enabled_opencode field to McpApps and SkillApps structures
- Add opencode field to McpRoot and PromptRoot
- Add database schema migration v3→v4 with enabled_opencode columns
- Add settings.rs support for opencode_config_dir and current_provider_opencode
- Create opencode_config.rs module for config file I/O operations
- Update all services (proxy, mcp, skill, provider, stream_check) for OpenCode
- Add OpenCode support to deeplink provider and MCP parsing
- Update commands/config.rs for OpenCode config status and paths
Key design decisions:
- OpenCode uses additive mode (no is_current needed, no proxy support)
- Config path: ~/.config/opencode/opencode.json
- MCP format: stdio→local, sse/http→remote conversion planned
- Stream check returns error (not yet implemented for OpenCode)
* feat(usage): improve custom template with variables display and explicit type detection
Combine two feature improvements:
1. Display supported variables ({{baseUrl}}, {{apiKey}}) with actual values in custom template mode
2. Add explicit templateType field for accurate template mode detection
## Changes
### Frontend
- Display template variables with actual values extracted from provider settings
- Add templateType field to UsageScript for explicit mode detection
- Support template mode persistence across sessions
### Backend
- Add template_type field to UsageScript struct
- Improve validation logic based on explicit template type
- Maintain backward compatibility with type inference
### I18n
- Add "Supported Variables" section translation (zh/en/ja)
### Benefits
- More accurate template mode detection (no more guessing)
- Better user experience with variable hints
- Clearer validation rules per template type
* fix(usage): resolve custom template cache and validation issues
Combine three bug fixes to make custom template mode work correctly:
1. **Update cache after test**: Testing usage script successfully now updates the main list cache immediately
2. **Fix same-origin check**: Custom template mode can now access different domains (SSRF protection still active)
3. **Fix field naming**: Unified to use autoQueryInterval consistently between frontend and backend
## Problems Solved
- Main provider list showing "Query failed" after successful test
- Custom templates blocked by overly strict same-origin validation
- Auto-query intervals not saved correctly due to inconsistent naming
## Changes
### Frontend (UsageScriptModal)
- Import useQueryClient and update cache after successful test
- Invalidate usage cache when saving script configuration
- Use standardized autoQueryInterval field name
### Backend (usage_script.rs)
- Allow custom template mode to bypass same-origin checks
- Maintain SSRF protection for all modes
### Hooks (useProviderActions)
- Invalidate usage query cache when saving script
## Impact
Users can now use custom templates freely while security validations remain intact for general templates.

- Add detailed debug logging for usage metrics
- Support cache_read_input_tokens field in Codex responses
- Fallback to input_tokens_details.cached_tokens if needed

suffix (after :), then matched exactly against pricing table.
* feat(database): add Chinese AI model pricing data
Add pricing for domestic AI models (CNY/1M tokens):
- Doubao-Seed-Code (ByteDance)
- DeepSeek V3/V3.1/V3.2
- Kimi K2/K2-Thinking/K2-Turbo (Moonshot)
- MiniMax M2/M2.1/M2.1-Lightning
- GLM-4.6/4.7 (Zhipu)
- Mimo V2 Flash (Xiaomi)
Also fix test case to use correct model ID and remove invalid currency column.
* refactor(proxy): improve header forwarding with blacklist approach
Change from whitelist to blacklist mode for request header forwarding.
Only skip headers that will be overridden (auth, host, content-length).
This preserves client's original headers and improves compatibility.
* fix(proxy): bypass timeout and retry configs when failover is disabled
When auto_failover_enabled is false, timeout and retry configurations
should not affect normal request flow. This change ensures:
- create_forwarder: passes 0 for all timeout/retry params when failover
is disabled, effectively bypassing these checks
- streaming_timeout_config: returns 0 for both first_byte_timeout and
idle_timeout when failover is disabled
This prevents unnecessary timeout errors and retry attempts when users
have explicitly disabled the failover feature.
* fix(proxy): handle zero value input in failover config fields
* refactor(proxy): remove retry logic and add enabled check for failover
* refactor(proxy): distinguish circuit-open from no-provider errors
* Align usage stats to sliding windows
* feat(proxy): add body and header filtering for upstream requests
* feat(proxy): enable transparent passthrough for headers
- Passthrough anthropic-beta header as-is from client
- Passthrough anthropic-version header from client
- Passthrough client IP headers (x-forwarded-for, x-real-ip) by default
- Filter private params (underscore-prefixed fields) from request body
- No database changes required
* feat(proxy): extract session ID from client requests for logging
- Add SessionIdExtractor to parse session ID from Claude/Codex requests
- Support extraction from metadata.user_id, headers, previous_response_id
- Pass session_id through RequestContext to usage logger
- Enable request correlation by session in proxy_request_logs
On Windows, opening the Settings > About section would spawn three
terminal windows when checking CLI tool versions (claude, codex, gemini).
Root cause:
- scan_cli_version() directly executed .cmd files, but child processes
(node.exe) spawned by these batch scripts didn't inherit CREATE_NO_WINDOW
- PATH separator used Unix-style ":" instead of Windows ";"
Fix:
- Wrap command execution with `cmd /C` to ensure all child processes
run within the same hidden console session
- Use platform-specific PATH separators via conditional compilation
* feat: add Universal Provider feature
- Add Universal Provider data structures and type definitions
- Implement backend CRUD operations and sync functionality
- Add frontend UI components (UniversalProviderPanel, Card, FormModal)
- Add NewAPI icon and preset configuration
- Support cross-app (Claude/Codex/Gemini) configuration sync
- Add website URL field for providers
- Implement real-time refresh via event notifications
- Add i18n support (Chinese/English/Japanese)
* feat: integrate universal provider presets into add provider dialog
- Add universal provider presets (NewAPI, Custom Gateway) to preset selector
- Show universal presets with Layers icon badge in preset selector
- Open UniversalProviderFormModal when universal preset is clicked
- Pass initialPreset to auto-fill form when opened from add dialog
- Add i18n keys for addSuccess/addFailed messages
- Keep separate universal provider panel for management
* refactor: move universal provider management to add dialog
- Remove Layers button from main navigation header
- Add 'Manage' button next to universal provider presets
- Open UniversalProviderPanel from within add provider dialog
- Add i18n keys for 'manage' in all locales
* style: display universal provider presets on separate line
- Move universal provider section to a new row with border separator
- Add label '统一供应商:' to clarify the section
* style: unify universal provider label style with preset label
- Use FormLabel component for consistent styling
- Add background to 'Manage' button matching preset buttons
- Update icon size and button padding for consistency
* feat: add sync functionality and JSON preview for Universal Provider
* fix: add missing in_failover_queue field to Provider structs
After rebasing to main, the Provider struct gained a new
`in_failover_queue` field. This fix adds the missing field
to the three to_*_provider() methods in UniversalProvider.
* refactor: redesign AddProviderDialog with tab-based layout
- Add tabs to separate app-specific providers and universal providers
- Move "Add Universal Provider" button from panel header to footer
- Remove unused handleAdd callback and clean up imports
- Update emptyHint i18n text to reference the footer button
* fix: append /v1 suffix to Codex base_url in Universal Provider
Codex uses OpenAI-compatible API which requires the /v1 endpoint suffix.
The Universal Provider now automatically appends /v1 to base_url when
generating Codex provider config if not already present.
- Handle trailing slashes to avoid double slashes
- Apply fix to both backend (to_codex_provider) and frontend preview
* feat: auto-sync universal provider to apps on creation
Previously, users had to manually click sync after adding a universal
provider. Now it automatically syncs to Claude/Codex/Gemini on creation,
providing a smoother user experience.

allowing independent proxy settings for Claude, Codex, and Gemini.
Add GlobalProxyConfig queries and per-app config management in DAO layer.
* feat(proxy): add GlobalProxyConfig and AppProxyConfig types
Add new type definitions for the refactored proxy configuration:
- GlobalProxyConfig: shared settings (enabled, address, port, logging)
- AppProxyConfig: per-app settings (failover, timeouts, circuit breaker)
* refactor(proxy): update service layer for per-app config structure
Adapt proxy service, handler context, and provider router to use
the new per-app configuration model. Read enabled/timeout settings
from proxy_config table instead of settings table.

Extract app_type from router key and read circuit breaker settings
from the corresponding proxy_config row for each application.
Add a terminal button next to each provider card that opens a new terminal
window with that provider's specific API configuration. This allows using
different providers independently without changing the global setting.
Changes:
- Backend: Add `open_provider_terminal` command that extracts provider
config and creates a temporary claude settings file
- Frontend: Add terminal button to provider cards with proper callback
propagation through component hierarchy
- Support macOS (Terminal.app), Linux (gnome-terminal, konsole, etc.),
and Windows (cmd)
Each provider gets a unique config file named `claude_<providerId>_<pid>.json`
in the temp directory, containing the provider's API configuration.

This commit addresses several critical issues in the failover system:
**Circuit breaker state persistence (previous fix)**
- Promote ProviderRouter to ProxyState for cross-request state sharing
- Remove redundant router.rs module
- Fix 429 errors to be retryable (rate limiting should try other providers)
**Hot-update circuit breaker config**
- Add update_circuit_breaker_configs() to ProxyServer and ProxyService
- Connect update_circuit_breaker_config command to running circuit breakers
- Add reset_provider_circuit_breaker() for manual breaker reset
**Fix HalfOpen deadlock bug**
- Change half_open_requests from cumulative count to in-flight count
- Release quota in record_success()/record_failure() when in HalfOpen state
- Prevents permanent deadlock when success_threshold > 1
**Fix duplicate select_providers() call**
- Store providers list in RequestContext, pass to forward_with_retry()
- Avoid consuming HalfOpen quota twice per request
- Single call to select_providers() per request lifecycle
**Add per-provider retry with exponential backoff**
- Implement forward_with_provider_retry() with configurable max_retries
- Backoff delays: 100ms, 200ms, 400ms, etc.
Add a new failover queue system that operates independently from provider
sortIndex, allowing users to configure failover order per app type.
Backend changes:
- Add failover_queue table to schema.rs for persistent storage
- Create dao/failover.rs with CRUD operations for queue management
- Add Tauri commands for queue operations (get, add, remove, reorder, toggle)
- Refactor provider_router.rs select_providers() to use failover queue:
- Current provider always takes first priority
- Queue providers ordered by queue_order as fallback
- Only providers with open circuit breakers are included
Frontend changes:
- Add FailoverQueueItem type to proxy.ts
- Extend failover.ts API with queue management methods
- Add React Query hooks for queue data fetching and mutations
- Create FailoverQueueManager component with drag-and-drop reordering
- Integrate queue management into SettingsPage under "Auto Failover"
- Add i18n translations for zh and en locales
The previous cleanup logic only sent a shutdown signal but didn't wait
for the proxy server to actually stop. This caused a race condition
where the app would exit before cleanup completed, leaving Live configs
in an inconsistent state.
Changes:
- Add `server_handle` field to ProxyServer to track the spawned task
- Modify `stop()` to wait for server task completion (5s timeout)
- Add 100ms delay before process exit to ensure I/O flush
- Export ProxyService and fix test files that were missing proxy_service field
* feat(ui): add color prop support to ProviderIcon component
* feat(health): add stream check core functionality
Add new stream-based health check module to replace model_test:
- Add stream_check command layer with single and batch provider checks
- Add stream_check DAO layer for config and log persistence
- Add stream_check service layer with retry mechanism and health status evaluation
- Add frontend HealthStatusIndicator component
- Add frontend useStreamCheck hook
This provides more comprehensive health checking capabilities.
* refactor(health): replace model_test with stream_check
Replace model_test module with stream_check across the codebase:
- Remove model_test command and service modules
- Update command registry in lib.rs to use stream_check commands
- Update module exports in commands/mod.rs and services/mod.rs
- Remove frontend useModelTest hook
- Update stream_check command implementation
This refactoring provides clearer naming and better separation of concerns.
* refactor(db): clean up unused database tables and optimize schema
Remove deprecated and unused database tables:
- Remove proxy_usage table (replaced by proxy_request_logs)
- Remove usage_daily_stats table (aggregation done on-the-fly)
- Rename model_test_logs to stream_check_logs with updated schema
- Remove related DAO methods for proxy_usage
- Update usage_stats service to use proxy_request_logs only
- Refactor usage_script to work with new schema
This simplifies the database schema and removes redundant data storage.
* refactor(ui): update frontend components for stream check
Update frontend components to use stream check API:
- Refactor ModelTestConfigPanel to use stream check config
- Update API layer to use stream_check commands
- Add HealthStatus type and StreamCheckResult interface
- Update ProviderList to use new health check integration
- Update AutoFailoverConfigPanel with stream check references
- Improve UI layout and configuration options
This completes the frontend migration from model_test to stream_check.
* feat(health): add configurable test models and reasoning effort support
Enhance stream check service with configurable test models:
- Add claude_model, codex_model, gemini_model to StreamCheckConfig
- Support reasoning effort syntax (model@level or model#level)
- Parse and apply reasoning_effort for OpenAI-compatible models
- Remove hardcoded model names from check functions
- Add unit tests for model parsing logic
- Remove obsolete model_test source files
This allows users to customize which models are used for health checks.
* fix(misc): improve CLI version detection with path scanning
- Extract version helper to parse semver from raw output
- Add fallback path scanning when direct execution fails
- Scan common npm global paths: .npm-global, .local/bin, homebrew
- Support nvm by scanning all node versions under ~/.nvm/versions/node
- Add platform-specific paths for macOS, Linux, and Windows
- Ensure node is in PATH when executing CLI tools from scanned paths
* fix(ui): use semantic color tokens for text foreground
- Replace hardcoded gray-900/gray-100 with text-foreground in EndpointSpeedTest
- Add text-foreground class to Input component for consistent theming
- Ensures proper text color in both light and dark modes
- Add cleanup_before_exit() to gracefully stop proxy and restore live configs
- Handle ExitRequested event to catch Cmd+Q, Alt+F4, and tray quit
- Use std::process::exit(0) after cleanup to avoid infinite loop
- Remove unused start_proxy_server and stop_proxy_server commands
- Remove unused startMutation and stopMutation from useProxyStatus hook
- Simplify API to only expose takeover mode (start_proxy_with_takeover/stop_proxy_with_restore)
Issues fixed:
1. Route prefix mismatch - Live config was set to use /claude, /codex,
/gemini prefixes but server only had routes without prefixes
2. Proxy targets not auto-configured - start_with_takeover only modified
Live config but didn't set is_proxy_target=true for current providers
Changes:
- Add prefixed routes (/claude/v1/messages, /codex/v1/*, /gemini/v1beta/*)
to server.rs for backward compatibility
- Remove URL prefixes from takeover_live_configs() - server can route
by API endpoint path alone (/v1/messages=Claude, /v1/chat/completions=Codex)
- Add setup_proxy_targets() method that automatically sets current providers
as proxy targets when starting proxy with takeover
- Unify proxy toggle in SettingsPage to use takeover mode (same as main UI)
- Fix error message extraction in useProxyStatus hooks
- Fix provider switch logic to check both takeover flag AND proxy running state
* feat(skill): add database migration and Gemini support for multi-app skills

- Update frontend API and components to support app-specific skill operations
* fix(usage): correct cache token column order in request log table
- Swap cache read and cache creation columns to match data binding
- Add whitespace-nowrap to all table headers for better display
