Add model catalog browsing, provider registry with form validation,
model fetch/test dialogs, and enhanced model management UI.
- Add model catalog API and catalog-dialog component for browsing saved models
- Add provider-registry with auto-populated form fields per provider
- Add provider-combobox, fetch-models-dialog, test-model-dialog components
- Add model-validation for provider-aware model ID validation
- Add command and popover UI components
- Enhance edit-model-sheet with tool schema transform support
- Add anthropic to protocolMetaByName for correct default API base
- Apply NormalizeBaseURL to anthropic provider for consistent URL handling
- Add i18n keys for new model management features (en/zh)
* fix(web): prevent auto-fetch when API key is missing in fetch models dialog
When a provider requires an API key but none is set, the dialog now shows
the warning without triggering a doomed fetch attempt. Fetch is deferred
until the user provides a key.
* fix(web): add credential warning for catalog imports from remote providers
When importing models from a catalog entry whose provider requires an API
key, a yellow warning banner now informs users that credentials will need
to be configured after import.
* feat(web,api): test connection with real connectivity verification and unsaved form values
Add POST /api/models/test-inline endpoint that performs actual network
probes (GET /models) instead of just checking config. Frontend Test
Connection now uses current form values (not saved state) and is
available in both Add and Edit model flows.
* style(web): apply linter formatting across model config components
Normalize quote style, import ordering, and class name ordering as
reported by the project linter.
* fix(web,api): fix edit test connection false negative and gate fetch for unsupported providers
- handleTestInlineModel now accepts optional model_index to fall back to stored credentials when api_key is empty, fixing false negatives when testing edited models
- Add supportsFetch to provider registry and FETCHABLE_PROVIDER_KEYS derived set
- Gate Fetch Models button to only show for OpenAI-compatible and Ollama providers
- Add backend guard in handleFetchModels to reject unsupported providers with clear error
* fix: address review feedback on model config workflow
- Send explicit {} for empty extra_body/custom_headers fields so the
backend clears stored values instead of preserving them
- Merge backend provider_options with frontend PROVIDERS registry so
the provider picker reflects backend-supported providers and policy
fields (create_allowed, default_auth_method, auth_method_locked)
- Render provider combobox popover inside the sheet scroll container
to fix wheel events scrolling the sheet instead of the provider list
* feat(web,api): add provider selection, model form foundation, and validation
Split from PR #2752 (part 1 of 3).
Backend:
- CRUD model endpoints (list/add/update/delete/set-default)
- Provider metadata with default API bases and model provider options
- Model ID validation and normalization
- Anthropic default API base normalization
Frontend:
- Provider registry with metadata, labels, icons, and aliases
- Provider combobox with backend option merging
- Model field validation with provider-aware checks
- Redesigned add/edit model sheets with provider selection
- Dynamic imports for fetch/catalog/test dialogs (coming in PR2/PR3)
- i18n support for model configuration UI
- Add isNetworkError detection for connection reset, broken pipe, read/write tcp, EOF
- Add retry logic with configurable exponential backoff for network errors
- Add config options max_llm_retries and llm_retry_backoff_secs in agents.defaults
- Network errors now retry with backoff (was previously not retried)
- Timeout errors now use configurable backoff instead of hardcoded 5s
- Default: 2 retries with 2s backoff (3 total attempts)
* refactor: support explicit model list providers
* fix(web): preserve explicit model providers
* fix(web): preserve legacy provider prefixes on model updates
fix(models): normalize explicit provider-prefixed ids
fix(api): preserve legacy model updates across providers
fix(agent): preserve config identity for explicit provider refs
* fix ci
Add reusable channel array list controls and parsing utilities for channel forms.
Normalize channel string-array payloads in the backend, including pasted values,
numeric IDs, hidden characters, duplicates, and empty clears.
Also allow FlexibleStringSlice to unmarshal null values and cover the new behavior
with backend and config tests.
Persist channel settings through the current channel_list schema, keeping common
channel fields at the top level and channel-specific fields under settings.
Return common fields and default config shapes from channel config endpoints, and
add coverage for nested patches, missing channel defaults, and secret handling.
Default the sample web search provider to auto, route Sogou vs DuckDuckGo dynamically based on query/UI language, and sync frontend language changes back to the backend so Current Service and runtime selection stay aligned.
