If there **is a `models` endpoint** in the `[[providers]]` AND there are `[[providers.models]]`, check the `models` endpoint but only fail with a **warning** if it errors + +## Project Structure Summary + +The implementation spans three key areas: + +1. **Schema Layer** (`forge.schema.json`): JSON Schema definition for configuration validation +2. **Config Layer** (`crates/forge_config/src/config.rs`): Rust struct definitions with Serde deserialization +3. **Repository Layer** (`crates/forge_repo/src/provider/provider_repo.rs`): Internal model handling with `Models` enum + +## Relevant Files + +| File | Purpose | Current State | +|------|---------|---------------| +| `forge.schema.json:613-689` | `ProviderEntry` schema | `models` accepts only `string \| null` | +| `crates/forge_config/src/config.rs:69-99` | `ProviderEntry` struct | `models: Option` | +| `crates/forge_repo/src/provider/provider_repo.rs:13-21` | Internal `Models` enum | Already supports `Url` and `Hardcoded` | +| `crates/forge_domain/src/model.rs:23-38` | Domain `Model` struct | Defines model fields | +| `crates/forge_repo/src/provider/provider.json` | Embedded provider configs | Uses hardcoded model arrays | +| `crates/forge_repo/src/provider/model_fetch.rs` | Model fetching logic | Currently requires models endpoint to succeed | + +## Implementation Plan + +### Phase 1: Schema Updates + +- [x] **Task 1.1**: Update `forge.schema.json` to define a new `ModelEntry` schema + + - Define `ModelEntry` object with fields matching `forge_domain::Model`: + - `id` (string, required): Model identifier + - `name` (string, optional): Human-readable model name + - `description` (string, optional): Model description + - `context_length` (integer, optional): Maximum context window + - `tools_supported` (boolean, optional): Tool use capability + - `supports_parallel_tool_calls` (boolean, optional): Parallel tool calls support + - `supports_reasoning` (boolean, optional): Reasoning support + - `input_modalities` (array of strings, optional): Supported input types (`["text"]`, `["text", "image"]`) + + - Update `ProviderEntry.models` field to accept `oneOf`: + - String (URL template for fetching models) + - Array of `ModelEntry` objects (static model list) + - Null (no model list) + +### Phase 2: Config Layer Updates + +- [x] **Task 2.1**: Create `StaticModelEntry` struct in `forge_config/src/config.rs` + + ```rust + #[derive(Debug, Clone, PartialEq, Serialize, Deserialize, JsonSchema, Dummy)] + pub struct StaticModelEntry { + pub id: String, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub name: Option, + // ... other optional fields + } + ``` + + - Follow existing patterns: use `#[serde(default, skip_serializing_if = "Option::is_none")]` for optional fields + - Use `derive_setters::Setters` for builder pattern support + - Add JSON Schema derive for schema generation + +- [x] **Task 2.2**: Create `ProviderModels` enum with untagged deserialization + + ```rust + #[derive(Debug, Clone, PartialEq, Deserialize, Serialize, JsonSchema)] + #[serde(untagged)] + pub enum ProviderModels { + Url(String), + Static(Vec), + } + ``` + + - Use `#[serde(untagged)]` for seamless backward compatibility with string URLs + - Keep serialization compatible with both formats + +- [x] **Task 2.3**: Update `ProviderEntry` struct to use new enum + + ```rust + pub struct ProviderEntry { + // ... existing fields ... + #[serde(default, skip_serializing_if = "Option::is_none")] + pub models: Option, + } + ``` + +### Phase 3: Repository Layer Updates + +- [x] **Task 3.1**: Update `From` conversion in `provider_repo.rs` + + - Modify line 158 to handle both `ProviderModels::Url` and `ProviderModels::Static` variants + - Map `Static` variant to existing `Models::Hardcoded` enum variant + - Ensure proper conversion of `StaticModelEntry` to `forge_app::domain::Model` + +- [x] **Task 3.2**: Verify existing `From<&ProviderConfig>` conversion (lines 165-192) works unchanged + + - Internal `Models` enum already supports both variants + - Conversion logic handles `Models::Hardcoded` correctly + +### Phase 4: Validation + +- [x] **Task 4.1**: Add runtime validation for static model entries + + - Validate `id` field is non-empty + - Validate `context_length` is positive if provided + - Validate `input_modalities` contains valid values (`"text"`, `"image"`) + +- [x] **Task 4.2**: Consider adding validation at config load time + + - Implement `Validate` trait or custom deserialization logic + - Provide clear error messages for invalid configurations + +### Phase 5: Model Endpoint Validation Relaxation (v2) + +- [ ] **Task 5.1**: Update model fetching logic to handle missing endpoint gracefully + + - Modify `crates/forge_repo/src/provider/model_fetch.rs` to check if `models` URL is provided + - If no `models` URL is provided and static models exist, skip endpoint fetch entirely + - If `models` URL is provided but fails, log a **warning** instead of failing hard + +- [ ] **Task 5.2**: Add logging for models endpoint scenarios + + - Log when skipping models endpoint fetch (static models present, no URL) + - Log warning when models endpoint fails (with URL present) + - Log info when models are fetched successfully from endpoint + +- [ ] **Task 5.3**: Update error handling in provider initialization + + - Change `Result` return type to handle models endpoint failures gracefully + - Use `tracing::warn!` for endpoint failures instead of `tracing::error!` + - Ensure static models are still usable even if endpoint fails + +### Phase 6: Testing Strategy + +- [x] **Task 6.1**: Unit tests for `ProviderModels` deserialization + + ```rust + #[test] + fn test_provider_models_url() { + let json = r#""https://api.example.com/models""#; + let models: ProviderModels = serde_json::from_str(json).unwrap(); + assert!(matches!(models, ProviderModels::Url(_))); + } + + #[test] + fn test_provider_models_static() { + let json = r#"[{"id": "gpt-4"}]"#; + let models: ProviderModels = serde_json::from_str(json).unwrap(); + assert!(matches!(models, ProviderModels::Static(_))); + } + ``` + +- [x] **Task 6.2**: Integration tests for full provider config parsing + + - Test inline provider with URL-based models + - Test inline provider with static model list + - Test mixed providers in single `ForgeConfig` + +- [x] **Task 6.3**: Round-trip serialization tests + + - Verify static model lists serialize back to valid JSON + - Verify URL strings remain unchanged + +- [x] **Task 6.4**: Backward compatibility tests + + - Verify existing URL-only configurations continue to work + - Test with various URL template formats + +- [ ] **Task 6.5**: New tests for models endpoint relaxation + + - Test static models work without any `models` URL + - Test static models still work when `models` URL fails (warning only) + - Test warning is logged when endpoint fails + - Test info is logged when endpoint succeeds + +### Phase 7: Documentation + +- [x] **Task 7.1**: Update schema documentation + + - Document both `models` format options in schema descriptions + - Add examples showing URL vs static list usage + +- [x] **Task 7.2**: Consider updating user-facing docs (optional) + + - Explain when to use URL-based vs static model lists + - Provide example configurations + +## Verification Criteria + +- [x] Existing URL-based model configurations continue to work without modification +- [x] New static model list configurations parse correctly from TOML +- [x] Schema validation passes for both format options +- [x] All existing tests pass (`cargo insta test --accept`) +- [x] Code compiles without warnings (`cargo check`) +- [x] Round-trip serialization preserves model data accurately +- [ ] Static models work correctly when no `models` URL is provided +- [ ] Models endpoint failures produce warnings, not errors (when URL is present) +- [ ] All new tests pass + +## Potential Risks and Mitigations + +1. **Risk**: Breaking change for existing configurations + - **Mitigation**: Untagged enum ensures backward compatibility with string URLs + - **Mitigation**: Extensive testing of existing URL-based configs + +2. **Risk**: Schema validation conflicts between URL and object formats + - **Mitigation**: Use `oneOf` in JSON Schema with clear type discrimination + - **Mitigation**: Rust untagged enum handles both cases automatically + +3. **Risk**: Inconsistent model field validation + - **Mitigation**: Align static model entry schema with domain `Model` struct fields + - **Mitigation**: Add runtime validation for required fields + +4. **Risk**: Merge semantics with hardcoded vs URL models + - **Mitigation**: Existing merge logic in `provider_repo.rs` already handles `Models` enum + - **Mitigation**: Verify merge behavior with both model source types + +5. **Risk** (v2): Models endpoint errors go unnoticed + - **Mitigation**: Ensure warnings are logged clearly with provider and endpoint context + - **Mitigation**: Document this behavior in configuration docs + +## Alternative Approaches + +1. **Separate Fields Approach**: Use `models_url` and `models_static` as separate fields + - **Trade-off**: More explicit but breaks compatibility + - **Trade-off**: Users must choose one or the other + +2. **Custom Deserializer Approach**: Keep string field but parse array syntax internally + - **Trade-off**: Simpler schema but less explicit + - **Trade-off**: Magic parsing could be confusing + +3. **Reuse Existing Domain Types**: Reference domain `Model` type directly in config + - **Trade-off**: DRY but couples config layer to domain layer + - **Trade-off**: May introduce unnecessary dependencies + +**Selected Approach**: Untagged enum with dedicated `StaticModelEntry` struct +- Preserves backward compatibility (URL strings deserialize directly) +- Clear separation of concerns (config vs domain) +- Follows existing codebase patterns (similar to `UrlParamVarConfig`) + +## Implementation Order + +1. ~~Update `forge.schema.json` first (schema drives validation)~~ +2. ~~Implement `StaticModelEntry` and `ProviderModels` in `forge_config`~~ +3. ~~Update `ProviderEntry` struct~~ +4. ~~Update conversion logic in `provider_repo.rs`~~ +5. ~~Add tests~~ (phases 1-4 complete) +6. **Implement models endpoint relaxation** (Phase 5 -
