Error Handling Integration Across Layers - -### 4.1 Domain models & ActionResponse - -In `src/guide/app/domain/models.py`: - -* Extend `ActionResponse` with error fields: - -```python -class ActionStatus(str, Enum): - SUCCESS = "success" - ERROR = "error" - -class ActionResponse(BaseModel): - status: ActionStatus - action_id: str - correlation_id: str - result: dict[str, Any] | None = None - error_code: str | None = None - message: str | None = None - details: dict[str, Any] | None = None -``` - -* When an action completes successfully, `status=SUCCESS` and `error_*` fields are `None`. -* When it fails, `status=ERROR` and `error_code/message/details` are populated from a `GuideError`. - -### 4.2 FastAPI route error handling - -In `src/guide/app/api/routes/actions.py`: - -* Ensure that `ActionResponse` is the canonical shape returned for `/actions/*`. -* Either: - - * Let `GuideError` bubble up to the global FastAPI exception handlers, or - * Catch `GuideError` in the route, create `ActionResponse(status=ERROR, ...)`, and return that. - -Pick one approach and stick with it; do not mix ad-hoc `JSONResponse`s and `ActionResponse` everywhere. - ---- - -## 5. How Actions Decide Between Browser vs GraphQL - -Add these architectural guidelines (comments/docs for the assistant): - -1. **Browser-first for interactive flows** - - * Actions that are meant to be visible during demos (live UI clicking, form filling) should use the **browser layer** (CDP/Playwright). - * They: - - * Use `BrowserClient.get_demo_page(...)`. - * Expect persona login to be handled by `auth.session.ensure_persona`. - -2. **GraphQL-first for purely backend tasks** - - * Background actions that don’t need UI (e.g., polling statuses, “prepare data before demo”, mass-updating metadata) should call the **GraphQL service** instead of automating the UI. - * These actions: - - * Get a `DemoPersona` for context (or a service persona). - * Use `raindrop.graphql.GraphQLClient` + `raindrop.operations.*`. - -3. **Hybrid actions** - - * Some scenarios may need both: - - * Use GraphQL to create or prepare data. - * Use browser actions to show the result in the demo. - * Hybrid actions must **still** route GraphQL calls through `raindrop.operations`, and browser calls through `BrowserClient`. - -4. **Error consistency** - - * Whether the failure happens in CDP attachment, MFA login, or GraphQL: - - * Lower-level code throws the appropriate `GuideError` subclass. - * The route or job layer converts that into a consistent `ActionResponse` or job status. - ---- - -## 6. Concrete TODOs for the Code Assistant - -You can give your agent this checklist: - -1. **Add `src/guide/app/errors/{exceptions.py,handlers.py}` and wire handlers into `app.main`’s FastAPI app.** -2. **Add `src/guide/app/utils/{ids.py,timing.py,retry.py,env.py}` and update:** - - * Logging to include correlation IDs where appropriate. - * Any flaky CDP attach logic or future GraphQL calls to optionally use `retry`. -3. **Extend `core/config.py` and `config/hosts.yaml` as previously specified AND add `raindrop_graphql_url` to `AppSettings`.** -4. **Create `src/guide/app/raindrop/graphql.py` and `src/guide/app/raindrop/operations/{intake.py,sourcing.py}` using the patterns above.** -5. **Create `src/guide/app/strings/graphql/{intake.py,sourcing.py}` to store GraphQL query strings.** -6. **Update `domain/models.py` to include error fields in `ActionResponse` and ensure the routes use it consistently.** -7. **Refactor existing (and future) code to:** - - * Use `GuideError` subclasses instead of generic exceptions where appropriate. - * Avoid inline strings for UI selectors, demo text, or GraphQL queries. - ---- - -You can drop this whole spec into your agent as the “next iteration instructions” and let it build out the `errors`, `utils`, and `raindrop` layers in a way that stays consistent with your existing modular architecture. - ---- - -## 3. Engineering & Code Style Standards (add-on) - -These apply to all new work in this repo. - -### Python & typing - -* Target Python **3.12+**; no `__future__` imports. -* Use **PEP 604 unions** (`str | None`) and **built-in generics** (`list[str]`, `dict[str, str]`); avoid `typing.List/Dict`. -* Do not use `typing.Any`; model shapes explicitly (e.g., `dict[str, str]`, `TypedDict`, `Protocol`, or data classes/Pydantic models). -* Avoid `# type: ignore`; prefer refactoring to satisfy type checkers. -* Use `Literal` for constrained status/enum-like strings. - -### Imports and organization - -* Import order: stdlib → third-party → internal. -* No wildcard imports. Keep line length ≤120 chars. -* Keep domain packages segmented (e.g., `app/actions//`, `app/strings//`); add submodules rather than expanding single files. - -### Pydantic & settings - -* Use **Pydantic v2** and `pydantic-settings`; no v1 compat shims. -* All configurable values flow through `AppSettings`; never hardcode hosts, ports, or URLs in business logic. - -### Actions and strings - -* Actions must import selectors/text from `app.strings`; no inline UI strings/selectors. -* Split actions once they exceed ~150 LoC to keep files focused. - -### Error handling and logging - -* Prefer structured errors (`{"error": "CODE", "message": "...", "correlation_id": "..."}`). -* Log correlation IDs on entry/exit for actions and browser connections when available. - -### Testing & validation - -* Bias toward unit/contract tests; when testing Playwright-dependent logic, mock the browser rather than driving real CDP in CI. -* Keep `python -m compileall src/guide` green as a minimum sanity gate.
