## Code Standards
### Python Style
- **Formatter**: Black (100 character line length)
- **Linter**: Ruff
- **Type Hints**: Required for all public APIs
- **Docstrings**: Google-style format
- **Formatter**: Black (88 character line length)
- **Import Sorter**: isort (black-compatible profile)
- **Linter**: Ruff (checks style, security, complexity)
- **Type Checker**: mypy (strict mode for core modules)
- **Type Hints**: Required for all public APIs and core modules
- **Docstrings**: Google-style format (module, class, function level)
### Example
```python
"""Module for path validation."""
from pathlib import Path
from typing import List
def validate_path(path: Path, allowed_roots: List[Path]) -> bool:
"""Validate path against allowed roots.

## Before Making Changes
1. **Check the development plan**: See `DEVELOPMENT_PLAN.md` for current phase and priorities
2. **Understand the architecture**: Read `docs/ARCHITECTURE.md`
3. **Follow the structure**: Keep code organized in appropriate modules (core/, ui/, utils/)
4. **Write tests first**: Use TDD approach - write tests before implementing
1. **Check the development plan**: See [DEVELOPMENT_PLAN.md](../../DEVELOPMENT_PLAN.md) - currently Phase 4 Complete, Phase 5 in planning
2. **Understand the architecture**: Read [docs/ARCHITECTURE.md](../../docs/ARCHITECTURE.md)
3. **Review actual implementation**: Look at existing modules in core/, ui/, utils/
4. **Follow the structure**: Keep code organized in appropriate modules
5. **Write tests**: Use pytest - write tests for new functionality
## Making Changes
1. **Run existing tests first**: `pytest tests -v`
2. **Create test file**: `tests/unit/test_*.py`
3. **Write failing test**: Verify it fails before implementing
4. **Implement feature**: Follow code standards above
5. **Run tests**: `pytest tests -v --cov`
6. **Run quality checks**: `tox -e lint,type`
7. **Update docs**: Add docstrings and update README if needed
1. **Run existing tests first**: `pytest tests -v` (should pass)
2. **Create test file**: `tests/unit/test_*.py` or `tests/integration/test_*.py`
3. **Write test**: Verify test executes (may fail if feature incomplete)
4. **Implement feature**: Follow code standards (black, ruff, isort, mypy)
5. **Format code**: `tox -e format` (auto-formats with black/isort)
6. **Run all checks**: `tox -e lint,type` (ruff, mypy validation)
7. **Run tests with coverage**: `pytest tests --cov=src/webdrop_bridge`
8. **Update docs**: Add/update docstrings, README if needed
## Development Environment
**Virtual Environment**: `.venv` (already created)
- Activate: `.venv\Scripts\activate` (Windows) or `source .venv/bin/activate` (macOS/Linux)
- All Python commands automatically use this environment through VS Code integration
- **Note**: Only activate if running commands outside VS Code terminal
**Required**:
- Python 3.9+ (tested on 3.10, 3.11, 3.12, 3.13, 3.14)
- PySide6 (for Qt GUI)
- pytest (for testing)
- tox (for automated testing and quality checks)

Target: 80%+ code coverage
- Use `pytest --cov=src/webdrop_bridge --cov-report=html` to generate coverage reports
- Review htmlcov/index.html for detailed coverage breakdown
## Performance Considerations
- Drag event handling: < 50ms total
- Application startup: < 1 second
- Memory baseline: < 200MB
- Logging overhead: minimize file I/O in drag operations
## Documentation Requirements
- **Public APIs**: Docstrings required
- **Public APIs**: Docstrings required (Google-style format)
- **Modules**: Add docstring at top of file
- **Features**: Update README.md and docs/
- **Integration tests**: Reference and document in README.md and docs/ARCHITECTURE.md
- **Breaking changes**: Update DEVELOPMENT_PLAN.md
- **Classes**: Document purpose, attributes, and usage in docstring
- **Functions**: Document args, returns, raises, and examples
- **Features**: Update [DEVELOPMENT_PLAN.md](../../DEVELOPMENT_PLAN.md) milestones
- **Architecture changes**: Update [docs/ARCHITECTURE.md](../../docs/ARCHITECTURE.md)
- **Config changes**: Update [CONFIG_README.md](../../CONFIG_README.md)
- **Breaking changes**: Update CHANGELOG.md and DEVELOPMENT_PLAN.md
- **Code examples**: Preferred format is in docstrings with >>> syntax

4. **Check docs/ARCHITECTURE.md**: Design patterns and data flow
1. **Check DEVELOPMENT_PLAN.md**: Current phase (Phase 4 Complete) and architecture decisions
2. **Look at tests**: Existing tests in `tests/unit/` and `tests/integration/` show expected behavior
3. **Read docstrings**: Functions document their contracts using Google-style format
4. **Check docs/ARCHITECTURE.md**: Design patterns, data flow, and module organization
5. **Review config examples**: See [CONFIG_README.md](../../CONFIG_README.md) and `config.example.json`

## What NOT to Do
❌ Change architecture without discussion
❌ Add dependencies without updating pyproject.toml
❌ Merge without tests passing
❌ Remove type hints or docstrings
❌ Commit without running `tox -e lint,type`
❌ Add platform-specific code without tests
❌ Change architecture without reviewing DEVELOPMENT_PLAN.md first
❌ Add dependencies without updating requirements-dev.txt and pyproject.toml
❌ Commit without running `tox -e format,lint,type`
❌ Remove type hints or docstrings from public APIs
❌ Add imports without running `tox -e format` (isort cleanup)
❌ Add platform-specific code without tests marked with @pytest.mark.windows or @pytest.mark.macos
❌ Modify path validation logic without security review
❌ Force-push to main or release branches
## Notes for Modifications
- This is a production-quality application, not a PoC
- Code quality and testing are non-negotiable
- Cross-platform support (Windows + macOS) is required
- User security (path validation) is critical
- Documentation must keep pace with code
- Code quality, testing, and documentation are non-negotiable
- Cross-platform support (Windows + macOS) is required and tested
- User security (path validation) is critical - be extra careful with path operations
- Configuration must support both .env files and JSON files
- All error messages should be meaningful and logged appropriately
- Documentation must keep pace with code changes
