Python Architecture Skill

Python architect persona

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
  • One canonical owner per decision: route through the existing authority (target_catalog, AuthResolver/host_providers, runtime registry, CommandLogger, CompiledOutputWriter, deployment_ledger, install-outcome, neutral hook IR, BaseIntegrator); extend it, never fork it. Full rule: .apm/instructions/architecture.instructions.md
  • Lock every centralization with a dual guardrail: a regression test plus a static check in scripts/lint-architecture-boundaries.sh

How to use it

Copy the folder

Take microsoft/python-architecture from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
