# Phase 1 Plan 2: Quality Tooling Summary

**Pre-commit hooks and quality automation with modern Ruff tooling, using uv dependency groups (PEP 735)**

## Performance

- **Duration:** 15 min
- **Started:** 2026-01-04T22:33:28Z
- **Completed:** 2026-01-04T22:48:57Z
- **Tasks:** 2
- **Files modified:** 9

## Accomplishments

- Configured Ruff for linting and formatting (replaces Black, isort, Flake8, pyupgrade, autoflake)
- Set up pre-commit hooks with Ruff, mypy, pytest with coverage
- Created shared test fixtures in conftest.py
- Updated README with development instructions using uv
- Migrated to modern dependency-groups (PEP 735) for dev dependencies
- Verified full installation and all quality checks pass

## Files Created/Modified

- `.pre-commit-config.yaml` - Pre-commit configuration with Ruff, mypy, pytest
- `pyproject.toml` (updated) - Added Ruff, pytest, coverage, mypy configuration; migrated to [dependency-groups]
- `tests/conftest.py` - Shared test fixtures (cli_runner, temp_env_file)
- `README.md` - Installation and development documentation with uv commands
- `src/n8n_cli/__main__.py` - Fixed to import and call `app` instead of `main`
- `src/n8n_cli/cli.py` - Entry point (script reference fixed in pyproject.toml)
- `src/n8n_cli/config.py` - Enhanced to properly support global config file loading

## Decisions Made

- **Ruff only**: Single tool for all linting/formatting (10-100x faster than Black+isort+Flake8)
- **80% coverage minimum**: Starting point, will raise as codebase grows
- **Lenient mypy**: `disallow_untyped_defs = false` for now, can tighten incrementally
- **No commitizen/vulture**: Simplified setup, can add later if needed
- **PEP 735 dependency-groups**: Modern uv approach instead of optional-dependencies

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 1 - Bug] Fixed CLI entry point to use app instead of main**
- **Found during:** Task 2 (Human verification)
- **Issue:** CLI commands `--version` and `--help` produced no output; entry point was calling callback function instead of Typer app
- **Fix:** Changed `pyproject.toml` script from `n8n_cli.cli:main` to `n8n_cli.cli:app`; updated `__main__.py` to import `app`
- **Files modified:** pyproject.toml, src/n8n_cli/__main__.py
- **Verification:** `uv run n8n --version` shows "n8n CLI version 0.1.0"
- **Commit:** (included in plan commit)

**2. [Rule 1 - Bug] Fixed global config file loading implementation**
- **Found during:** Task 1 (Running pre-commit pytest)
- **Issue:** Test `test_load_from_global_config` was failing; config.py wasn't properly reading from global config file
- **Fix:** Implemented proper file reading with environment variable precedence in N8nConfig.load()
- **Files modified:** src/n8n_cli/config.py
- **Verification:** All 8 tests pass; coverage at 91%
- **Commit:** (included in plan commit)

**3. [Rule 1 - Bug] Migrated to PEP 735 dependency-groups**
- **Found during:** Task 1 (Pre-commit hook configuration)
- **Issue:** pytest not available when using `[project.optional-dependencies]`; modern uv uses different approach
- **Fix:** Changed to `[dependency-groups]` which is the proper PEP 735 / modern uv standard
- **Files modified:** pyproject.toml
- **Verification:** `uv sync --dev` properly installs all dev dependencies; `uv run pytest` works
- **Commit:** (included in plan commit)

---

**Total deviations:** 3 auto-fixed (all bugs discovered during execution)
**Impact on plan:** All fixes necessary for correct operation. Migrating to dependency-groups is best practice for uv 0.9+.

## Issues Encountered

None - all issues were auto-fixed during execution

## Next Phase Readiness

Phase 1 (Foundation & Configuration) is complete. Ready for Phase 2 (API Client & Core Types).

**Foundation established:**
- ✅ Modern project structure (src layout)
- ✅ Type-safe configuration system (Pydantic with global config support)
- ✅ CLI framework (Typer with working --version and --help)
- ✅ Quality tooling (Ruff, pre-commit, pytest with 91% coverage)
- ✅ All quality checks passing
- ✅ Modern uv dependency management (PEP 735 dependency-groups)

**Next up:**
Phase 2 will build the n8n API client using httpx with proper field filtering and error handling.
