CLI Architecture Pattern

This is a reference pattern. Learn from the approach, adapt to your context — don't copy verbatim.

Problem: Infrastructure operations scattered across shell scripts, manual commands, and deployment pipelines become hard to maintain and inconsistent.

Solution: Structured CLI tools with uniform entry points.

Why This Pattern?

Benefits:

• Consistency: Same commands work locally, in CI/CD, and deployment scripts
• Readability: pnpm deploy:dev is clearer than raw AWS CLI commands
• Testability: CLI commands can be tested independently
• Reusability: Share logic across different entry points
• Documentation: Commands are self-documenting with --help
