ABOUTME: Orchestrates pattern selection and delegates to language-specific skills

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 |
