Senior Engineering Toolkit

This skill embodies the practices of disciplined software engineering.

Sub-Skills

1. TDD Enfrocer

When writing new features:

1. Red: Write the test FIRST. Ensure it fails for the right reason.
2. Green: Write the minimum code to pass the test.
3. Refactor: Clean up the code while keeping tests green.

2. Clean Architecture

Enforce the dependency rule: Source Code Dependencies must point only inward, toward higher-level policies.

• Entities (Domain) should not know about Database or Web frameworks.
• Use Interfaces/Ports to invert dependencies.

3. Automated Refactoring

Strategies for cleaning code:

• Extract Method: Reduce function size.
• Replace Conditional with Polymorphism: Remove switch statements.
• Introduce Parameter Object: Simplify method signatures.

Usage

Apply these heuristics whenever designing or implementing core business logic.
