# Phase 6 Plan 3: Shell Completion Summary

**Dynamic shell completion for workflow/project names from n8n API and file paths using Typer's autocompletion system**

## Performance

- **Duration:** 32 min
- **Started:** 2026-01-05T20:35:12Z
- **Completed:** 2026-01-05T21:07:43Z
- **Tasks:** 4 (3 auto, 1 checkpoint)
- **Files modified:** 6

## Accomplishments

- Dynamic shell completion for workflow and project names from n8n API
- File path completion for .json workflow files
- Completion integrated into workflow, project, and member commands
- Graceful error handling (silent failures don't break completion)
- Installation documentation in README
- Comprehensive testing confirmed completion works in zsh

## Files Created/Modified

- `src/n8n_cli/completion.py` - Three completion functions (workflows, projects, files)
- `src/n8n_cli/cli.py` - Enabled completion in Typer app (add_completion=True)
- `src/n8n_cli/commands/workflow.py` - Added completion to 9 commands
- `src/n8n_cli/commands/project.py` - Added completion to project view
- `src/n8n_cli/commands/member.py` - Added completion to 3 member commands
- `README.md` - Shell completion documentation section

## Decisions Made

- **Removed project filtering from workflow completion** - WorkflowsResource.list() doesn't support project_id parameter, so completion shows all workflows (simpler and faster)
- **Silent error handling in completion functions** - Return empty list on any error to ensure completion never breaks commands
- **Modern Python type hints** - Used built-in `list[str]` instead of `typing.List[str]` for Python 3.9+ compatibility

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Fixed WorkflowsResource.list() parameter error**
- **Found during:** Task 3 (Manual testing of completion)
- **Issue:** Completion function was calling `client.workflows.list(project_id=project_id)` but the list() method only accepts `active` parameter, causing TypeError
- **Fix:** Removed project filtering logic from complete_workflows(), now calls `client.workflows.list()` without parameters
- **Files modified:** src/n8n_cli/completion.py
- **Verification:** Completion function returns workflow names successfully
- **Commit:** Included in main commit

**2. [Rule 1 - Bug] Fixed line length violations**
- **Found during:** Task 2 (Running ruff checks)
- **Issue:** Five function signatures exceeded 100 character line limit
- **Fix:** Split long function signatures across multiple lines for better readability
- **Files modified:** src/n8n_cli/commands/workflow.py
- **Verification:** `ruff check` passes with all checks green
- **Commit:** Included in main commit

**Total deviations:** 2 auto-fixed (1 blocking, 1 bug), 0 deferred
**Impact on plan:** Both fixes were necessary for correct operation. No scope creep.

## Issues Encountered

- **Completion script installation confusion:** User initially ran `uv run n8n --install-completion` which creates completion for the wrapped command. Solution: Activate venv first so `n8n` is directly available
- **Old completion script conflict:** User had old `~/.n8n-complete.zsh` with wrong environment variable that conflicted with new `.zfunc/_n8n` completion. Solution: Reload completion from correct source

## Next Step

**Phase 6 complete!** All developer experience features implemented:
- ✅ Utility functions (detect_project_context, save_workflow, etc.)
- ✅ Progressive verbosity (standardized count=True across all commands)
- ✅ Shell completion (workflows, projects, files)

Ready for **Phase 7: Quality & Testing** - comprehensive test suite expansion and pre-commit hooks.
