--- description: "Task list for MFA authentication flow with garth integration" --- # Tasks: Update Authentication Flow for MFA with garth **Input**: Design documents from `/specs/007-update-the-authentication/` **Prerequisites**: plan.md (required), spec.md (required for user stories), research.md, data-model.md, contracts/ **Tests**: The examples below include test tasks. Tests are OPTIONAL - only include them if explicitly requested in the feature specification. **Organization**: Tasks are grouped by user story to enable independent implementation and testing of each story. ## Format: `[ID] [P?] [Story] Description` - **[P]**: Can run in parallel (different files, no dependencies) - **[Story]**: Which user story this task belongs to (e.g., US1, US2, US3) - Include exact file paths in descriptions ## Path Conventions - **Single project**: `src/`, `tests/` at repository root - **Web app**: `backend/src/`, `frontend/src/` - **Mobile**: `api/src/`, `ios/src/` or `android/src/` - Paths shown below assume single project - adjust based on plan.md structure ## Phase 1: Setup (Shared Infrastructure) **Purpose**: Project initialization and basic structure - [x] T001 Create project structure in cli/ directory following implementation plan - [x] T002 Set up Python 3.13 virtual environment and install required dependencies (Click, httpx, pydantic, pytest, garth, garminconnect) - [x] T003 Create requirements.txt with pinned dependencies following constitution standards - [x] T004 Create pyproject.toml with Black, Flake8, Mypy, Isort configurations - [x] T005 [P] Create initial directory structure (src/, models/, services/, commands/, utils/, tests/) --- ## Phase 2: Foundational (Blocking Prerequisites) **Purpose**: Core infrastructure that MUST be complete before ANY user story can be implemented **⚠️ CRITICAL**: No user story work can begin until this phase is complete - [x] T006 Create base data models for User Session, Sync Job, and Authentication Token in src/models/ - [x] T007 [P] Implement API client to interact with backend API endpoints in src/api/client.py - [x] T008 [P] Create configuration management utilities for YAML config in src/utils/config.py - [x] T009 [P] Implement token management with secure local storage in src/auth/token_manager.py - [x] T010 Create output formatting utilities (JSON, table, CSV) in src/utils/output.py - [x] T011 [P] Implement CLI entry point with base command structure in src/main.py **Checkpoint**: Foundation ready - user story implementation can now begin in parallel --- ## Phase 3: User Story 1 - Text-Based Authentication with MFA (Priority: P1) 🎯 MVP **Goal**: Implement authentication functionality via text-based interface with MFA support so users can securely access the system. **Independent Test**: Can be fully tested by running the authentication command with both standard credentials and MFA-enabled accounts, and verifying the system properly validates credentials and handles MFA flows. ### Tests for User Story 1 (OPTIONAL - only if tests requested) ⚠️ **NOTE: Write these tests FIRST, ensure they FAIL before implementation** - [x] T012 [P] [US1] Contract test for auth endpoint in tests/contract/test_auth_api.py - [x] T013 [P] [US1] Integration test for auth flow in tests/integration/test_auth_flow.py ### Implementation for User Story 1 - [x] T014 [US1] Create AuthManager class to handle authentication flows with MFA support in src/auth/auth_manager.py - [x] T015 [US1] Implement MFA handling functionality in AuthManager - [x] T016 [US1] Create authentication command implementation in src/commands/auth_cmd.py - [x] T017 [US1] Add interactive authentication mode with secure input prompts - [x] T018 [US1] Implement token validation and refresh logic - [x] T019 [US1] Add error handling for authentication failures - [x] T020 [US1] [P] Write unit tests for authentication manager in tests/unit/test_auth_manager.py - [x] T021 [US1] [P] Write integration tests for authentication flows in tests/integration/test_auth_flow.py **Checkpoint**: At this point, User Story 1 should be fully functional and testable independently --- ## Phase 4: User Story 2 - Trigger Sync Operations via Text Interface (Priority: P2) **Goal**: Implement functionality to trigger sync operations from text-based interface so users can initiate data synchronization without using the web interface. **Independent Test**: Can be fully tested by authenticating and then running the sync trigger command, and verifying that the sync process is initiated in the backend system. ### Tests for User Story 2 (OPTIONAL - only if tests requested) ⚠️ - [x] T022 [P] [US2] Contract test for sync trigger endpoint in tests/contract/test_sync_trigger.py - [x] T023 [P] [US2] Integration test for sync triggering in tests/integration/test_sync_operations.py ### Implementation for User Story 2 - [x] T024 [US2] Create SyncCommand class to handle sync triggering functionality in src/commands/sync_cmd.py - [x] T025 [US2] Implement sync trigger API call functionality - [x] T026 [US2] Add support for different sync types (activities, health, workouts) - [x] T027 [US2] Implement date range and full sync options - [x] T028 [US2] Add authentication validation before sync triggers - [x] T029 [US2] Handle sync conflict detection (concurrent sync requests) - [x] T030 [US2] [P] Write unit tests for sync command functionality in tests/unit/test_commands.py - [x] T031 [US2] [P] Write integration tests for sync triggering in tests/integration/test_sync_operations.py **Checkpoint**: At this point, User Stories 1 AND 2 should both work independently --- ## Phase 5: User Story 3 - Check Sync Status via Text Interface (Priority: P3) **Goal**: Implement functionality to check sync operation status from text-based interface so users can monitor data synchronization progress. **Independent Test**: Can be fully tested by triggering a sync and then checking its status via the text interface, with various sync states being properly reported. ### Tests for User Story 3 (OPTIONAL - only if tests requested) ⚠️ - [x] T032 [P] [US3] Contract test for sync status endpoint in tests/contract/test_sync_status.py - [x] T033 [P] [US3] Integration test for status checking in tests/integration/test_sync_status.py ### Implementation for User Story 3 - [x] T034 [US3] Create StatusCommand class to handle sync status checking in src/commands/sync_cmd.py - [x] T035 [US3] Implement sync status API call functionality - [x] T036 [US3] Add support for retrieving specific job status by ID - [x] T037 [US3] Format status output in multiple formats (table, JSON, CSV) - [x] T038 [US3] Handle status requests for non-existent sync jobs - [x] T039 [US3] [P] Write unit tests for status command functionality in tests/unit/test_commands.py - [x] T040 [US3] [P] Write integration tests for status checking in tests/integration/test_sync_status.py **Checkpoint**: All user stories should now be independently functional --- ## Phase N: Polish & Cross-Cutting Concerns **Purpose**: Improvements that affect multiple user stories - [x] T041 [P] Documentation updates in docs/ - [x] T042 Code cleanup and refactoring - [x] T043 Performance optimization across all stories - [x] T044 [P] Additional unit tests (if requested) in tests/unit/ - [x] T045 Security hardening - [x] T046 Run quickstart.md validation --- ## Dependencies & Execution Order ### Phase Dependencies - **Setup (Phase 1)**: No dependencies - can start immediately - **Foundational (Phase 2)**: Depends on Setup completion - BLOCKS all user stories - **User Stories (Phase 3+)**: All depend on Foundational phase completion - User stories can then proceed in parallel (if staffed) - Or sequentially in priority order (P1 → P2 → P3) - **Polish (Final Phase)**: Depends on all desired user stories being complete ### User Story Dependencies - **User Story 1 (P1)**: Can start after Foundational (Phase 2) - No dependencies on other stories - **User Story 2 (P2)**: Can start after Foundational (Phase 2) - Depends on US1 authentication - **User Story 3 (P3)**: Can start after Foundational (Phase 2) - Depends on US1 authentication ### Within Each User Story - Tests (if included) MUST be written and FAIL before implementation - Models before services - Services before endpoints - Core implementation before integration - Story complete before moving to next priority ### Parallel Opportunities - All Setup tasks marked [P] can run in parallel - All Foundational tasks marked [P] can run in parallel (within Phase 2) - Once Foundational phase completes, all user stories can start in parallel (if team capacity allows) - All tests for a user story marked [P] can run in parallel - Models within a story marked [P] can run in parallel - Different user stories can be worked on in parallel by different team members --- ## Implementation Strategy ### MVP First (User Story 1 Only) 1. Complete Phase 1: Setup 2. Complete Phase 2: Foundational (CRITICAL - blocks all stories) 3. Complete Phase 3: User Story 1 4. **STOP and VALIDATE**: Test User Story 1 independently 5. Deploy/demo if ready ### Incremental Delivery 1. Complete Setup + Foundational → Foundation ready 2. Add User Story 1 → Test independently → Deploy/Demo (MVP!) 3. Add User Story 2 → Test independently → Deploy/Demo 4. Add User Story 3 → Test independently → Deploy/Demo 5. Each story adds value without breaking previous stories ### Parallel Team Strategy With multiple developers: 1. Team completes Setup + Foundational together 2. Once Foundational is done: - Developer A: User Story 1 - Developer B: User Story 2 (after authentication component ready) - Developer C: User Story 3 (after authentication component ready) 3. Stories complete and integrate independently --- ## Notes - [P] tasks = different files, no dependencies - [Story] label maps task to specific user story for traceability - Each user story should be independently completable and testable - Verify tests fail before implementing - Commit after each task or logical group - Stop at any checkpoint to validate story independently - Avoid: vague tasks, same file conflicts, cross-story dependencies that break independence
