+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+SmileyFace is a Python CLI tool for automating Unreal Tournament 4 (UT4) server administration. It handles building local server instances from custom maps/mutators/configs, deploying them to remote game and redirect servers via rsync/SSH, and managing server lifecycle (start/stop/restart).
+
+## Commands
+
+```bash
+# Install dependencies
+poetry install
+
+# Run the tool
+python smileyface.py --help
+
+# Format code
+black smileyface/
+isort --profile black --filter-files smileyface/
+
+# Lint
+flake8 smileyface/
+
+# Run pre-commit hooks manually
+pre-commit run --all-files
+```
+
+There is no test suite.
+
+## Code Style
+
+- **Black** formatter: 120 char line length, target Python 3.13
+- **isort**: profile black, multi_line_output=3, trailing commas, force_grid_wrap=3
+- **flake8**: 120 char max, ignores E121/E123/E126/E226/E24/E704/W605
+
+## Architecture
+
+The app uses **Click** for CLI dispatch, **pydantic-settings** for configuration, and stdlib `logging` for log management.
+
+**Entry point**: `smileyface.py` (project root) imports `smileyface.start_app()` which invokes the Click CLI.
+
+**Configuration**: `AppSettings` (`settings.py`) is a pydantic `BaseSettings` model. Config is loaded from environment variables (prefix `SMILEYFACE_`) or a `.env` file. See `.env.example` for all available settings.
+
+**Context**: `AppContext` (`context.py`) holds the `settings` instance and a dict-like `log` accessor. Passed to all command classes as `ctx`.
+
+**CLI**: `cli.py` defines Click commands that instantiate the context and delegate to class methods.
+
+**Key classes**:
+- `UT4ServerMachine` (`hub_machine.py`) - Core logic. Each CLI subcommand (generate_instance, upload_server, upload_redirects, etc.) is a method here. This is the largest and most important file.
+- `DataLayer` (`datalayer/datalayer.py`) - Lazy SQLite3 connection wrapper.
+- `DbFuncs` (`datalayer/db_ops.py`) - Database operations for tracking pak file state (MD5 sums, validation).
+- `GameIniSpecial` (`gameconfig_edit.py`) - Generates redirect references in Game.ini for custom pak files.
+
+**Deployment flow**: `oneclickdeploy` chains `generate_instance` -> `upload_redirects` -> `upload_server`. The generate step builds a local instance directory with the server binary, configs, maps, and mutators. Upload steps rsync to remote hosts.
+
+**Scraping module** (`scrape_latest/`) uses Selenium to scrape pak file listings from ut4pugs.us and utcc.unrealpugs.com for MD5 validation against local files.
