Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Python development with FastAPI, Django, or Flask. Async patterns, type hints, project structure. Use when building Python backends, scripts, or choosing Python frameworks. NOT for Node.js projects (use nodejs-pro) or general AI agents (use google-adk-python).Key capabilities
- →Select the appropriate Python framework based on project scope and scale.
- →Classify workloads as I/O-bound or CPU-bound to decide between async and sync.
- →Define architecture layering with routes, services, and repositories.
- →Enforce type hints on all public APIs.
- →Utilize Pydantic for input/output validation.
- →Provide recommendations for background tasks using Celery.
How it works
The skill uses a decision tree and classification rules to recommend Python frameworks and architectural patterns based on project requirements. It provides guidelines for type hinting and project structure.
Inputs & outputs
When to use python-pro
- →Choosing a Python framework
- →Structuring a Python backend
- →Planning async architectures
About this skill
Python Backend Engineering
Build typed, observable Python systems with explicit ownership of blocking work and lifecycle state.
Workflow
- Confirm the supported Python version, packaging tool, deployment target, and concurrency model.
- Choose a framework from product requirements rather than popularity.
- Isolate transport, domain, persistence, and integration boundaries.
- Validate external data at entry points and type public interfaces.
- Keep blocking work outside the event loop; add deadlines and cancellation to I/O.
- Define structured errors, logging, metrics, startup, shutdown, and rollback behavior.
- Test behavior at unit, integration, and contract boundaries.
Routing
| Concern | Read |
|---|---|
| Framework decision | framework-selection.md |
| Package boundaries | project-structure.md |
| Async and cancellation | async-patterns.md |
| FastAPI | fastapi-patterns.md |
| Django | django-patterns.md |
| Type contracts | type-hints.md |
| Tests | testing-patterns.md |
| Cross-cutting gate | engineering-spec.md |
Release Gate
Require locked dependencies, type checking, deterministic tests, migration review, timeouts for external I/O, graceful shutdown, and redacted diagnostics. Fail when a required check cannot run.
When not to use it
- →When working on Node.js projects.
- →When the task is general AI agent development.
- →When the task involves API design, testing strategy, or database schema.
Limitations
- →The skill focuses on Python development with FastAPI, Django, or Flask.
- →The skill produces recommendations and does not write code.
- →The skill does not cover API design, testing strategy, or database schema.
How it compares
This skill provides deterministic recommendations for Python framework selection and architecture based on specific criteria, unlike general programming advice.
