Server Development Skill

Instructions

Use this skill to scaffold and maintain backend services in the server/ directory. Follow the stack preferences and configuration details below.

Quick Start

1. Initialize: uv init.
2. Manager: Use uv for all dependency operations.
3. Framework: Setup FastAPI with Pydantic.
4. Database: configure SQLAlchemy (Async) + Alembic.

Core Stack Preferences

Project Management (uv)

Use uv for all Python project management (scaffolding, dependency management, virtual environments).

Command	Description
uv init	Initialize a new project
uv add <pkg>	Add dependency
uv add --dev <pkg>	Add development dependency
uv run <cmd>	Run command in virtual environment
uv venv	Create virtual environment

Project Location

The backend project should be initialized in the server/ directory.

Framework (FastAPI)

Use FastAPI for building APIs.

• Use APIRouter for modularizing routes.
• Use pydantic-settings for configuration management.

Database (SQLAlchemy + Alembic)

Use SQLAlchemy 2.0+ with AsyncIO support. Use Alembic for database migrations.

AI & LLM (LiteLLM + Docling)

• LiteLLM: For standardized access to various LLM providers.
• Docling: For parsing and processing documents.
