How do I install the Python Coding skill?

Run npx skillmds@latest add rbozydar/python-coding in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Python Coding safe to use?

This skill has not completed SkillMD's automated safety review yet. Capability flags: docs only. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Python Coding?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Python Coding free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

Python Coding

This skill should be loaded when writing, reviewing, or refactoring Python code to apply strict coding standards directly in the current context without spawning a subagent. It provides comprehensive Python development standards covering SOLID principles, asyncio patterns, type hints, testing, and production-quality code.

Python Coder Standards

Apply these standards when writing, reviewing, or refactoring Python code. This provides the same expertise as the python-coder agent but applied directly in the current conversation context.

Quick Reference Checklist

Before providing any code or review, verify:

Absolute imports only
Modern type hints (X | None)
No prohibited practices (eval, exec, global, print, bare except, mutable defaults)
Pydantic validation at boundaries
No blocking I/O in async paths
asyncio.TaskGroup for structured concurrency
Google-style docstrings on public APIs
Structured logging (no f-strings in logger calls)
No assertions in production code
Immutable types preferred (tuple > list, frozenset > set)

See references/python-standards.md for full details on each item.

Detailed Standards

For the complete standards reference covering all patterns, examples, and anti-patterns, load:

references/python-standards.md

This reference covers:

Design Principles - SOLID, dependency injection, composition over inheritance
Asyncio & Concurrency - TaskGroup, firewall pattern, non-blocking I/O, synchronization
Fault Tolerance - Exception isolation for independent tasks
Error Handling - Exception hierarchy, no assertions in production
Logging - Structured logging patterns
Input Validation - Pydantic models at boundaries
Naming & Immutability - PEP 8, no built-in shadowing, immutable defaults
Imports & Type Hints - Absolute imports, modern syntax, Protocols
Testing - TDD with pytest, async testing patterns
Prohibited Practices - Complete list of banned patterns with alternatives

Output Guidelines

When writing code:

Provide complete, runnable code with all imports
Include type hints on all parameters and return values
Add Google-style docstrings to public APIs
Show example usage when helpful

When reviewing code:

Reference specific violations from the standards
Explain WHY each change is needed
Provide corrected code
Prioritize by severity
