Backend covers REST and GraphQL APIs, frameworks such as Django, FastAPI, Laravel and Express, microservices, queues and migrations. Skills here describe project layout, error handling, input validation and how the agent should run tests and migrations. Prefer skills tied to your framework and its major version. Generic backend best-practice skills mostly repeat what the model already knows. A good sign is a skill that explains how to start the environment and run the tests with one command.
