Best AI Agent Skills for Python Developers (2026)

Python developers have some of the best SKILL.md skill options available. Whether you're building web APIs with FastAPI, data pipelines with pandas, or full applications with Django, there are skills that encode best practices for each workflow.

Web framework skills

FastAPI skills

FastAPI has clear conventions that translate well into agent skills. The best FastAPI skills handle endpoint generation with proper Pydantic models, dependency injection patterns, async/await best practices, and automatic OpenAPI documentation. They ensure your agent generates type-safe endpoints with proper error handling rather than quick-and-dirty route handlers.

Django skills

Django skills are particularly valuable because the framework is opinionated — there's a "Django way" to do most things, and encoding those patterns in a skill means your agent follows them consistently. Look for skills that handle model design with proper migrations, class-based views, Django REST Framework serializers, and template patterns.

Testing skills

pytest skills

A good pytest skill teaches your agent to write tests that use fixtures properly, parametrize test cases, mock external dependencies correctly, and follow the arrange-act-assert pattern. The difference between a generic "write tests" request and one guided by a pytest skill is substantial — you get proper conftest.py organization, fixture scoping, and mark decorators.

Type checking skills

Python's type system is powerful but inconsistent across codebases. A mypy or pyright skill ensures your agent adds proper type annotations, uses Protocol classes for structural subtyping, and handles Optional/Union types correctly. These skills are particularly valuable for codebases transitioning from untyped to typed Python.

Data science skills

Skills for data science workflows handle pandas best practices (avoiding chained indexing, proper use of .loc/.iloc), NumPy vectorization patterns, and Jupyter notebook organization. They also help with data pipeline patterns — reading from various sources, transformation chains, and output formatting.

Package management skills

Poetry and pip-tools have specific conventions for dependency management. A packaging skill ensures your agent generates proper pyproject.toml configurations, handles version constraints correctly, and follows the project structure conventions for publishable packages.
