# Phase 3 Plan 1: WorkflowsResource API Methods Summary

**Complete CRUD and utility methods for WorkflowsResource with create/update/delete/activate/deactivate/find_by_name, all type-safe with retry logic and 100% test coverage**

## Performance

- **Duration:** 53 min
- **Started:** 2026-01-04T23:38:43Z
- **Completed:** 2026-01-05T00:32:02Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments

- Extended WorkflowsResource from 2 methods to 8 methods (list, get, create, update, delete, activate, deactivate, find_by_name)
- All methods use @retry decorator with exponential backoff (2s/4s/8s) and ServerError handling for production resilience
- Implemented CRUD operations (create, update, delete) returning type-safe Pydantic Workflow models
- Added activate/deactivate convenience methods using PATCH for partial updates
- Built find_by_name() utility for flexible CLI input resolution with exact matching and duplicate detection
- Achieved 100% test coverage with 16 new test methods covering all new functionality plus retry behavior
- Updated existing retry decorators to include ServerError for complete 5xx error handling
- All quality gates passing: pytest (21 tests), ruff, mypy

## Files Created/Modified

- `src/n8n_cli/client/resources/workflows.py` - Added create/update/delete/activate/deactivate/find_by_name methods with @retry decorators, updated list/get retry decorators to include ServerError
- `tests/test_workflows_resource.py` - Added 16 new test methods across 6 test classes verifying all new methods including retry behavior, edge cases, and error handling

## Decisions Made

1. **ServerError in retry logic** - Updated all retry decorators (including existing list/get) to include ServerError for proper handling of 5xx transient failures. Critical for production resilience since handle_response() raises ServerError for 5xx codes.

2. **PATCH for activate/deactivate** - Used PATCH (not PUT) for partial updates as specified in plan, following REST best practices for partial resource modification.

3. **find_by_name error handling** - Implemented ValueError when multiple workflows have the same name to prevent ambiguity in CLI commands. Case-sensitive exact matching ensures predictable behavior.

4. **Type annotations** - Added explicit type annotations and moved type ignore comments to resolve mypy issues while maintaining type safety and Pydantic support.

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 2 - Missing Critical] Added ServerError to retry decorators**
- **Found during:** Task 1 (create/update/delete implementation)
- **Issue:** Retry decorator only caught httpx.HTTPError and ConnectionError, but handle_response() raises ServerError for 5xx codes. This meant 5xx errors would not be retried, causing failures on transient server issues.
- **Fix:** Added ServerError to all retry decorators across all WorkflowsResource methods (list, get, create, update, delete, activate, deactivate)
- **Files modified:** src/n8n_cli/client/resources/workflows.py
- **Verification:** Tests verify retry behavior on ServerError responses
- **Commit:** 87c702a

**2. [Rule 3 - Blocking] Fixed mypy type checking error in find_by_name**
- **Found during:** Task 2 verification
- **Issue:** Type ignore comment on method signature interfered with list comprehension type inference, causing mypy failure
- **Fix:** Moved type ignore comment to the variable assignment instead of method signature
- **Files modified:** src/n8n_cli/client/resources/workflows.py
- **Verification:** mypy passes with no errors
- **Commit:** 9fa7a98

---

**Total deviations:** 2 auto-fixed (1 missing critical, 1 blocking), 0 deferred
**Impact on plan:** Both auto-fixes essential for production resilience and type safety. No scope creep.

## Issues Encountered

None - plan executed smoothly following established patterns from Phase 2.

## Next Phase Readiness

Phase 3 Plan 1 complete. Ready for **03-02-PLAN.md (Basic Workflow CLI Commands)**.

**WorkflowsResource API foundation established:**
- ✅ Complete CRUD operations (create, update, delete)
- ✅ Read operations with filtering (list with active filter, get by ID)
- ✅ Utility methods (activate, deactivate, find_by_name)
- ✅ All methods type-safe with Pydantic validation
- ✅ Production-ready retry logic with exponential backoff
- ✅ 100% test coverage with comprehensive edge case testing

**Next up:**
Phase 3 Plan 2 will implement basic workflow CLI commands (list, view, create, delete) using the complete WorkflowsResource API established in this plan.
