# Plan 01-01: Project Scaffold Summary

**Installable Python package with 7 subpackage directories, all dependencies declared, and build/lint/test tooling configured.**

## What was built

Created the complete vmcluster-mcp Python project structure:
- `pyproject.toml` with all runtime deps (mcp[cli], pydantic, asyncssh, libvirt-python, PyYAML) and dev deps (pytest, ruff, pytest-asyncio, pytest-mock)
- 7 subpackage directories matching design doc section 2.5
- ruff configured (line-length=120, py311 target, E/F/I/UP rules)
- pytest configured (asyncio_mode=auto, testpaths=tests)

## Verification

- `uv sync` completed successfully (47 packages installed including libvirt-python)
- All 7 subpackage imports succeed
- `ruff check .` passes
- pytest collection succeeds (no tests yet)

## Self-Check: PASSED
