But just a copy-paste of a piece of a project of mine

        ## Core Principles (IMPORTANT)
        - **NO FALLBACKS EVER** - Fail fast, fail hard. If something is missing, crash immediately
        - **NO SILENT DEFAULTS** - Never use default values when files/data is missing
        - **NO TRY/EXCEPT WRAPPING** - Let exceptions propagate for easier debugging
        - **PROPER TYPES ONLY** - Use Literal types for enums, Pydantic models for structures. No tuples for structured data
        - **NO JAVA-STYLE ABSTRACTIONS** - Don't create pointless constants like STATUS_OK = "OK". Just use literals or proper types
        - **PROPER PARSING** - No regex for structured formats, use real parsers
        - **CRASH EARLY** - Things should crash as soon and as hard as possible for easy debugging
        - **NO DEFENSIVE PROGRAMMING** - Don't worry about "backwards compatibility" during refactoring - just redesign things to be better.

        ## Development

        **IMPORTANT: Always use `uv run` for all Python commands. Never use plain `python` or `python3`.**

        ```bash
        # Format code
        uv run ruff format .

        # Check linting
        uv run ruff check .

        # Type checking
        uv run ty check

        # Run tests
        uv run pytest tests/
        ```
