- Add private helper method `execute_and_format_usage_result` to eliminate code duplication
- Refactor `query_usage` to use helper method instead of duplicating result processing
- Add new `test_usage_script` method to test temporary script without saving
- Add backend command `test_usage_script` accepting script content as parameter
- Register new command in lib.rs invoke_handler
- Add frontend `usageApi.testScript` method to call the new backend API
- Update `UsageScriptModal.handleTest` to test current editor content instead of saved script
- Improve DX: users can now test script changes before saving
Implement Solution A (complete deferred submission) for custom endpoint
management, replacing the dual-mode system with unified local staging.
Changes:
- Remove immediate backend saves from EndpointSpeedTest
* handleAddEndpoint: local state update only
* handleRemoveEndpoint: local state update only
* handleSelect: remove lastUsed timestamp update
- Add explicit clear detection in ProviderForm
* Distinguish "user cleared endpoints" from "user didn't modify"
* Pass empty object {} as clear signal vs null for no-change
- Fix mergeProviderMeta to handle three distinct cases:
* null/undefined: don't modify endpoints (no meta sent)
* empty object {}: explicitly clear endpoints (send empty meta)
* with data: add/update endpoints (overwrite)
Fixed Critical Bug:
When users deleted all custom endpoints, changes were not saved because:
- draftCustomEndpoints=[] resulted in customEndpointsToSave=null
- mergeProviderMeta(meta, null) returned undefined
- Backend interpreted missing meta as "don't modify", preserving old values
Solution:
Detect when user had endpoints and cleared them (hadEndpoints && length===0),
then pass empty object to mergeProviderMeta as explicit clear signal.
Architecture Improvements:
- Transaction atomicity: all fields submitted together on form save
- UX consistency: add/edit modes behave identically
- Cancel button: true rollback with no immediate saves
- Code simplification: removed ~40 lines of immediate save error handling
Testing:
- TypeScript type check: passed
- Rust backend tests: 10/10 passed
- Build: successful
Add optional accessToken and userId fields to usage query scripts,
enabling queries to authenticated endpoints like /api/user/self.
Changes:
- Add accessToken and userId fields to UsageScript type (frontend & backend)
- Extend script engine to support {{accessToken}} and {{userId}} placeholders
- Update NewAPI preset template to use /api/user/self endpoint
- Add UI inputs for access token and user ID in UsageScriptModal
- Pass new parameters through service layer to script executor
This allows users to query usage data from endpoints that require
login credentials, providing more accurate balance information for
services like NewAPI/OneAPI platforms.
Add compatibility for providers that use ANTHROPIC_API_KEY instead of
ANTHROPIC_AUTH_TOKEN, enabling support for AiHubMix and similar services.
Changes:
- Backend: Add fallback to ANTHROPIC_API_KEY in credential extraction
- migration.rs: Support API_KEY during config migration
- services/provider.rs: Extract credentials from either field
- Frontend: Smart API key field detection and management
- getApiKeyFromConfig: Read from either field (AUTH_TOKEN priority)
- setApiKeyInConfig: Write to existing field, preserve user choice
- hasApiKeyField: Detect presence of either field
- Add AiHubMix provider preset with dual endpoint candidates
- Define apiKeyField metadata for provider presets (documentation)
Technical Details:
- Uses or_else() for zero-cost field fallback in Rust
- Runtime field detection ensures correct field name preservation
- Maintains backward compatibility with existing configurations
- Priority: ANTHROPIC_AUTH_TOKEN > ANTHROPIC_API_KEY
Upgrade Claude model configuration from dual-key to quad-key system for
better model tier differentiation.
**Breaking Changes:**
- Replace `ANTHROPIC_SMALL_FAST_MODEL` with three granular keys:
- `ANTHROPIC_DEFAULT_HAIKU_MODEL`
- `ANTHROPIC_DEFAULT_SONNET_MODEL`
- `ANTHROPIC_DEFAULT_OPUS_MODEL`
**Backend (Rust):**
- Add `normalize_claude_models_in_value()` for automatic migration
- Implement fallback chain: `DEFAULT_* || SMALL_FAST || MODEL`
- Auto-cleanup: remove legacy `SMALL_FAST` key after normalization
- Apply normalization across 6 critical paths:
- Add/update provider
- Read from live config
- Write to live config
- Refresh config snapshot
**Frontend (React):**
- Expand UI from 2 to 4 model input fields
- Implement smart fallback in `useModelState` hook
- Update `useKimiModelSelector` for Kimi model picker
- Add i18n keys for Haiku/Sonnet/Opus labels (zh/en)
**Configuration:**
- Update all 7 provider presets to new format
- DeepSeek/Qwen/Moonshot: use same model for all tiers
- Zhipu: preserve tier differentiation (glm-4.5-air for Haiku)
**Backward Compatibility:**
- Old configs auto-upgrade on first read/write
- Fallback chain ensures graceful degradation
- No manual migration required
Closes #[issue-number]
- Extract internal functions in commands/mcp.rs and commands/provider.rs
to enable unit testing without Tauri context
- Add test hooks: set_mcp_enabled_test_hook, import_mcp_from_claude_test_hook,
import_mcp_from_codex_test_hook, import_default_config_test_hook
- Migrate error types from String to AppError for precise error matching in tests
- Extend ProviderService with delete() method to unify Codex/Claude cleanup logic
- Add comprehensive test coverage:
- tests/mcp_commands.rs: command-level tests for MCP operations
- tests/provider_service.rs: service-level tests for switch/delete operations
- Run cargo fmt to fix formatting issues (EOF newlines)
- Update BACKEND_REFACTOR_PLAN.md to mark phase 3 complete
Architecture improvements:
- Extract ProviderService with switch/backfill/write methods
- Reduce command layer from 160 to 13 lines via delegation
- Separate business logic (services) from state management (commands)
- Introduce precise error handling with structured validation
Refactoring details:
- Split Codex/Claude switching into symmetric private methods
- Add multi-layer validation for Codex auth field (existence + type)
- Extract import_config_from_path for command and test reuse
- Expose export_config_to_file and ProviderService in public API
Test coverage:
- Add 10+ integration tests for Claude/Codex switching flows
- Cover import/export success and failure scenarios (JSON parse, missing file)
- Verify state consistency on error paths (current remains unchanged)
- Test snapshot backfill for both old and new providers after switching
