Design Patterns

Architectural patterns implemented consistently across Go, Python, Bash, and Terraform.

Quick Reference

Pattern	Go	Python	Bash	Terraform
DI	Interfaces	Protocols	Functions	Variables/Modules
Errors	error return	Exceptions	Exit codes	Validation blocks
Config	Env + struct	Pydantic Settings	Env vars	tfvars files
Logging	log/slog	logging	stderr functions	N/A
Testing	go test	pytest	bats	terraform validate

Pattern Selection

What are you working on?

• Dependency Injection → See references/cross-language.md Section 1
• Error Handling → See references/cross-language.md Section 2
• Configuration → See references/cross-language.md Section 3
• Logging → See references/cross-language.md Section 4
• Testing Heuristics → See references/cross-language.md Section 5
• Background Jobs → See references/cross-language.md Section 6
• Anti-Patterns → See references/cross-language.md Section 7
• Naming Conventions → See references/cross-language.md Section 8

Workflow

1. Identify the pattern needed from the selection above
2. Read the reference for cross-language examples
3. Invoke language skill for implementation:
   • Go code → /golang
   • Python code → /python
   • Bash script → /bash
   • Terraform → /terraform

When to Use This Skill

• Discussing architectural decisions across multiple languages
• Ensuring consistency in error handling, DI, or config patterns
• Reviewing code for anti-patterns
• Establishing naming conventions for a polyglot project
• Teaching or documenting cross-language standards

Language-Specific Implementation

After reviewing the pattern, invoke the appropriate language skill:

Language	Skill	When
Go	/golang	Writing .go files
Python	/python	Writing .py files
Bash	/bash	Writing .sh files
Terraform	/terraform	Writing .tf files
