What problem does it solve? When maintaining multiple Litestar-related skills or projects, style rules like PEP 604 unions, async I/O, ruff/mypy/pyright configuration, and pytest conventions get duplicated and drift apart. This Skill provides a single shared style baseline that sibling skills link to instead of duplicating. ## Core Features & Use Cases - Shared Reference Files: Six focused references covering general principles, Python, Litestar, TypeScript, testing (pytest/vitest), and CI/CD (GitHub Actions, pre-commit, uv). - Single-Source-of-Truth Workflow: Generic rules live here exactly once; sibling skills link to only the references matching their language/framework mix. - Authoring Guardrails: Enforces terse, imperative rules with one-line justifications, copy-pasteable examples, and validation checklists to prevent duplication. - Use Case: When two sibling skills both write "use ruff format, never black", pull the rule into references/python.md once and replace the duplicates with links. ## Quick Start Ask the AI to review your Litestar project's Python code against the shared styleguide baseline for PEP 604 unions, async I/O, and docstring conventions.
