What problem does it solve?

The Developer Specialist skill guides engineers to progress designs and implementations with minimal, precise changes, embracing TDD (RED→GREEN→REFACTOR) and diff-driven thinking to ensure quality and speed, while preventing design bleed from unclear responsibilities or duplication.

Core Features & Use Cases

• Minimal-iteration design & implementation: apply RED→GREEN→REFACTOR to deliver small, test-driven changes.
• Guard against design bleed: enforce clear responsibilities, avoid duplication, and refrain from provisional compromises.
• Diff-driven reviews: produce review-friendly changes with explicit rationale and traceability.
• Use Case: When starting a feature, outline responsibilities, write a failing test, implement the minimal code to pass, and refactor for clarity.

Quick Start

Provide a feature brief and ask the AI to generate a minimal, test-first design, including responsibilities, a small test, and a plan to implement with RED→GREEN→REFACTOR.
