# Development Guidelines
|
|
|
|
This document contains critical information about working with this codebase. Follow these guidelines precisely.
|
|
|
|
## Core Development Rules
|
|
|
|
1. Package Management
|
|
- ONLY use uv, NEVER pip
|
|
- Installation: `uv add package`
|
|
- Running tools: `uv run tool`
|
|
- Upgrading: `uv add --dev package --upgrade-package package`
|
|
- FORBIDDEN: `uv pip install`, `@latest` syntax
|
|
|
|
2. Code Quality
|
|
- Type hints required for all code
|
|
- Public APIs must have docstrings
|
|
- Functions must be focused and small
|
|
- Follow existing patterns exactly
|
|
- Line length: 88 chars maximum
|
|
|
|
3. Testing Requirements
|
|
- Framework: `uv run pytest`
|
|
- Async testing: use anyio, not asyncio
|
|
- Coverage: test edge cases and errors
|
|
- New features require tests
|
|
- Bug fixes require regression tests
|
|
|
|
4. Version Control
|
|
- Commit messages: conventional format (fix:, feat:)
|
|
- PR scope: minimal, focused changes
|
|
- PR requirements: description, test plan
|
|
- Always include issue numbers
|
|
- Quote handling:
|
|
```bash
|
|
git commit -am "\"fix: message\""
|
|
gh pr create --title "\"title\"" --body "\"body\""
|
|
```
|
|
|
|
## Code Formatting
|
|
|
|
1. Ruff
|
|
- Format: `uv run ruff format .`
|
|
- Check: `uv run ruff check .`
|
|
- Fix: `uv run ruff check . --fix`
|
|
- Critical issues:
|
|
- Line length (88 chars)
|
|
- Import sorting (I001)
|
|
- Unused imports
|
|
- Line wrapping:
|
|
- Strings: use parentheses
|
|
- Function calls: multi-line with proper indent
|
|
- Imports: split into multiple lines
|
|
|
|
2. Type Checking
|
|
- Tool: `uv run pyright`
|
|
- Requirements:
|
|
- Explicit None checks for Optional
|
|
- Type narrowing for strings
|
|
- Version warnings can be ignored if checks pass
|
|
|
|
3. Pre-commit
|
|
- Config: `.pre-commit-config.yaml`
|
|
- Runs: on git commit
|
|
- Tools: Prettier (YAML/JSON), Ruff (Python)
|
|
- Ruff updates:
|
|
- Check PyPI versions
|
|
- Update config rev
|
|
- Commit config first
|
|
|
|
## Error Resolution
|
|
|
|
1. CI Failures
|
|
- Fix order:
|
|
1. Formatting
|
|
2. Type errors
|
|
3. Linting
|
|
- Type errors:
|
|
- Get full line context
|
|
- Check Optional types
|
|
- Add type narrowing
|
|
- Verify function signatures
|
|
|
|
2. Common Issues
|
|
- Line length:
|
|
- Break strings with parentheses
|
|
- Multi-line function calls
|
|
- Split imports
|
|
- Types:
|
|
- Add None checks
|
|
- Narrow string types
|
|
- Match existing patterns
|
|
|
|
3. Best Practices
|
|
- Check git status before commits
|
|
- Run formatters before type checks
|
|
- Keep changes minimal
|
|
- Follow existing patterns
|
|
- Document public APIs
|
|
- Test thoroughly |
