language-python

name: language-python description: Python language patterns and best practices. Use when language python guidance is required or when selecting a primary language for non-trivial automation. allowed-tools:

• Bash(uv)
• Bash(uvx)
• Bash(ruff)
• Bash(ty)
• Bash(pytest)

Key Execution Capabilities

Code Validation

• Run syntax and type checking: uvx ruff check, uvx ty
• Execute linting and formatting with ruff: uvx ruff format
• Run tests with pytest: uvx pytest
• Validate project structure and dependencies

Tool Integration

• Use ruff for linting, formatting, and code analysis
• Use ty for fast type checking
• Leverage uvx for one-off tool execution without installation
• Apply pytest for testing frameworks

Execution Context

• Process Python files from filesystem layer
• Generate structured reports with findings
• Create minimal, rule-compliant patches for violations
• Maintain separation between governance rules and execution tools

Error Handling

This skill provides execution-layer error handling for Python code analysis:

• Invalid Python syntax or imports
• Missing dependencies or tools
• Type checking failures (ty)
• Test execution errors

Usage Notes

• Always delegate to governance rules for policy decisions
• Focus on concrete tool execution and result processing
• Provide deterministic, tool-first analysis results
• Maintain separation between rule definition and rule application
