One of 9 test cases the skill fixed. Same model, same prompt, with and without the skill.
We have a middle-man class in our service layer that simply delegates calls to a backend client without adding behavior. Which atomic refactoring technique eliminates this unnecessary middle-man delegation?
| Checked | Without skill | With skill |
|---|---|---|
| The response identifies Inline as the primary atomic transformation to eliminate middle man delegators. | Missed | Passed |

Based on the Refactoring Priority Premise (RPP) from the Alcor Academy curriculum.
Execute levels in mandatory sequence. Lower levels before higher.
Focus: eliminate clutter, improve naming, remove dead code. Smells: Dead Code | Comments (how-comments) | Speculative Generality | Lazy Class. Transformations: Rename | Extract (variables/constants) | Safe Delete. Impact: 80% of readability improvement value. Test smells: Obscure Test | Hard-Coded Test Data | Assertion Roulette.
Focus: method extraction, duplication elimination. Smells: Long Method | Duplicate Code | Complex Conditionals. Transformations: Extract (methods) | Move (common code). Impact: 20% additional readability improvement. Test smells: Eager Test | Test Code Duplication | Conditional Test Logic.
Focus: class responsibilities, coupling reduction. Smells: Large Class | Feature Envy | Inappropriate Intimacy | Data Class | Divergent Change | Shotgun Surgery. Transformations: Move | Extract (classes). Test smells: Test Class Bloat | Mystery Guest | General Fixture.
Focus: parameter objects, value objects, abstractions. Smells: Long Parameter List | Data Clumps | Primitive Obsession | Middle Man. Transformations: Extract (objects) | Inline | Move.
Focus: Strategy | State | Command patterns. Smells: Switch Statements | complex state-dependent behavior. Transformations: Extract (interfaces) | Move (to polymorphic structure).
Focus: SOLID principles, architectural patterns.
