Python Development

Use this only for Python 3.12+ code. Keep language-agnostic rules out of this skill.

Read First

Read principles.md before generating or changing Python code.

Core Rules

• Prefer existing project patterns over these defaults.
• Inspect the project Python target before using 3.12-only syntax.
• Prefer stdlib and existing dependencies before adding packages.
• Validate untyped boundary input before it spreads.
