# Phase 3 Plan 4: Advanced Workflow Commands Summary

**Four advanced workflow commands shipped: diff, delete, move (placeholder), and open**

## Accomplishments

- Implemented `workflow diff` command with progressive verbosity levels (0-4) showing increasingly detailed comparisons between local and cloud workflow versions
- Implemented `workflow delete` command with confirmation prompt and --force flag
- Implemented `workflow move` command as placeholder for Phase 5 (requires projects API)
- Implemented `workflow open` command to launch workflows in browser
- Added comprehensive test coverage for all new commands (44 tests total for workflow commands)
- All tests passing, code passes mypy and ruff checks

## Files Created/Modified

- `src/n8n_cli/commands/workflow.py` - Added diff/delete/move/open commands and _compare_nodes helper function
- `tests/commands/test_workflow.py` - Added test classes for TestWorkflowDiff, TestWorkflowDelete, TestWorkflowMove, TestWorkflowOpen

## Decisions Made

**Diff Command Verbosity Levels:**
- Level 0 (no -v): Show which top-level fields changed and list nodes added/removed/modified
- Level 1 (-v): Add field changes with values (30 char truncation)
- Level 2 (-vv): Field changes with 300 char truncation
- Level 3 (-vvv): Field-level diffs (show before → after)
- Level 4 (-vvvv): Complete node-by-node diffs

**Move Command as Placeholder:**
The `workflow move` command was implemented as a placeholder that shows an informative message about Phase 5. This decision maintains API completeness while deferring implementation until the projects API is available (Phase 5).

**Open Command URL Construction:**
The open command properly strips `/api/v1` from the instance_url if present, since the workflow edit page is at the root URL (`/workflow/{id}`), not under the API path.

**Delete Command Confirmation:**
By default, delete requires confirmation via `typer.confirm()`. The --force flag skips this for automation/scripting use cases. The confirmation uses `abort=True` to exit cleanly when user declines.

## Issues Encountered

**Line Length Violations:**
Initial implementation had lines exceeding 100 characters in the diff comparison logic. Fixed by splitting long ternary expressions across multiple lines with proper indentation.

**No Major Blockers:**
Implementation went smoothly. All commands work as specified in the plan.

## Next Phase Readiness

Phase 3 (Workflow Management) complete. Ready for Phase 4 (Execution Management).

**Workflow commands implemented:**
- ✅ list (with filtering)
- ✅ view (name/ID resolution)
- ✅ pull (to local files)
- ✅ push (from local files)
- ✅ create (with ID update)
- ✅ delete (with confirmation)
- ✅ activate / deactivate
- ✅ diff (progressive verbosity)
- ✅ open (browser launch)
- ⏸️ move (placeholder for Phase 5)
- ⏸️ retry (deferred to Phase 4 - requires execution API)

**Next up:**
Phase 4 will implement execution management commands (list, view, download, retry) which will also enable the workflow retry command.
