# Phase 1 Plan 1: Foundation Setup Summary

**Project structure initialized with modern Python tooling and type-safe configuration**

## Accomplishments

- Created src layout project structure with pyproject.toml
- Implemented Pydantic-based configuration system with .env and global config support
- Built basic Typer CLI with version command
- All tests passing (8/8)

## Files Created/Modified

- `pyproject.toml` - Project configuration with modern dependencies (Typer, Pydantic, httpx, Ruff)
- `README.md` - Basic project documentation
- `src/n8n_cli/__init__.py` - Package init
- `src/n8n_cli/__main__.py` - Entry point for python -m
- `src/n8n_cli/cli.py` - Typer CLI app with version command
- `src/n8n_cli/config.py` - Pydantic BaseSettings configuration loader
- `tests/test_config.py` - Configuration tests with TDD (5 tests)
- `tests/test_cli.py` - Basic CLI tests (3 tests)
- `.gitignore` - Python gitignore entries
- `uv.lock` - Locked dependencies

## Decisions Made

- **Typer over Click**: Modern type-hint driven CLI framework (cleaner syntax, still uses Click under the hood)
- **Pydantic BaseSettings**: Type-safe configuration with validation instead of plain python-dotenv
- **src layout**: Industry standard project structure for 2026
- **httpx dependency**: Added for Phase 2 API client (modern, async-ready)
- **pre-commit version**: Adjusted from >=6.0 to >=4.0 (latest available)
- **Removed [all] from typer**: Typer 0.21.0 doesn't have an 'all' extra

## TDD Workflow Applied

For the configuration system (Task 2):
1. **RED**: Wrote 5 failing tests for config loading scenarios
2. **GREEN**: Implemented N8nConfig with Pydantic BaseSettings
3. All tests pass with proper precedence handling

## Test Results

```
8 passed in 0.10s
- 3 CLI tests (version, help, no-args)
- 5 Config tests (local env, global config, precedence, missing, env override)
```

## Verification Checklist

- [x] `ls src/n8n_cli/` shows all source files (__init__.py, __main__.py, cli.py, config.py)
- [x] `cat pyproject.toml` shows Typer, Pydantic, httpx, Ruff dependencies
- [x] `pytest` passes all tests (test_config.py, test_cli.py)
- [x] `python -m n8n_cli --version` works
- [x] `python -m n8n_cli --help` shows help text

## Issues Encountered

- **pre-commit version**: Plan specified >=6.0 but latest is 4.5.1 - adjusted to >=4.0 (non-blocking)
- **typer[all] extra**: Typer 0.21.0 doesn't provide 'all' extra - removed brackets (non-blocking)
- **README.md missing**: Build system required README.md referenced in pyproject.toml - created basic README

All issues were auto-fixed per deviation rules (Rule 1: auto-fix bugs, Rule 3: auto-fix blocking issues).

## Performance Metrics

- Duration: ~15 minutes
- Files modified/created: 10 files
- Tests written: 8 tests
- All tests passing
- Commits: 2 (test commit, implementation commit)

## Next Step

Ready for 01-02-PLAN.md (Quality Tooling setup with Ruff and pre-commit hooks)
