+description: Technology stack decisions for Python services. Use when adding dependencies, choosing infrastructure, bootstrapping projects, or reviewing tool choices.
+---
+
+## Rules
+- Use `uv` as the package manager for all Python dependency operations.
+- Use `FastAPI` for REST API and HTTP services.
+- Use `SQLModel` and `SQLAlchemy` for database access. Async drivers: `asyncpg` for PostgreSQL, `aiosqlite` for SQLite.
+- Use `alembic` for database migrations.
+- Use `facet` for hierarchical async service composition with dependency management and graceful shutdown.
+- Use `typer` for CLI interfaces.
+- Use `pydantic` for DTOs and data validation; use `pydantic-settings` for application configuration.
+- Use `loguru` for logging.
+- Use `pyyaml` for YAML parsing; use `pyyaml-include` for `!include` tags and `pyyaml-env-tag` for `!env` interpolation inside YAML config files.
