Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install fastapi-sqlalchemy-backend-implementation

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent writes or changes the FastAPI backend: routes, Pydantic v2 schemas, async SQLAlchemy 2.0 models, service and repository layers, error handling and Alembic migrations. It follows dependency injection with Depends().
