Pyroxin

Python-specific idioms, philosophy, and expert-level patterns. Use when working with Python code, including Jupyter notebooks (.ipynb). Covers Pythonic thinking, common pitfalls from other language backgrounds, testing ecosystem navigation, type hints trade-offs, and when to use modern Python features.

Core software engineering philosophy and design principles based on Structure and Interpretation of Computer Programs (SICP). Use for all software development tasks including writing code, designing systems, refactoring, or making architectural decisions. MUST ALWAYS be loaded when working on any kind of software development or design task!

Object-oriented design principles, patterns, and practices. Use when working with object-oriented languages (Java, C#, C++, Python, Ruby, Swift, etc.) without language-specific skills available, or when applying OOP in multi-paradigm codebases.

Pedagogical framework for teaching programming through Socratic dialogue. Use when a learner wants to LEARN programming rather than have code written for them. Triggers include "teach me", "help me understand", "I'm learning", "tutor mode", or requests to not provide solutions. Emphasizes productive struggle, graduated hints, metacognitive scaffolding, and emotional support.

Expert-level guidance for creating high-quality Claude Code skills. Use alongside Anthropic's skill-creator when creating new skills, improving existing skills, or needing guidance on skill content quality. Complements basic skill mechanics with research-driven content development, XML tag structuring, decision frameworks over mechanics, cross-references between skills, and systematic validation.

Deprecated name; the skill formerly here is now opinionated-research:interactive-research. Retained as a context-level notice because Claude Code now ships a built-in deep-research workflow that runs one-shot, non-interactive fan-out research (no conversation after the report). interactive-research instead runs a persistent agent team you can keep questioning once the report lands.
