python-architecture

The python-architecture skill activates a Python architect persona to guide structural decisions in the apm_cli codebase, particularly for new modules, class hierarchies, design patterns, and cross-cutting concerns. Use it when creating Python packages, refactoring multiple related files, implementing established patterns like BaseIntegrator or CommandLogger, or optimizing performance-sensitive operations across the APM CLI architecture.

# Python Architecture Skill

[Python architect persona](../../agents/python-architect.agent.md)

## When to activate

- Creating new Python modules or packages under `src/apm_cli/`
- Refactoring class hierarchies or introducing base classes
- Changes that touch 3+ files with shared logic patterns
- Introducing new design patterns (Strategy, Observer, etc.)
- Cross-cutting concerns (logging, auth, error handling)
- Performance-sensitive paths (parallel downloads, large manifests)

## Key rules

- Follow existing patterns (BaseIntegrator, CommandLogger, AuthResolver) before inventing new ones
- Prefer composition over deep inheritance
- Push shared logic into base classes, not duplicated across siblings
