Code quality score: F (-257). 💀 Not a typo. Negative two hundred and fifty-seven. Four use cases between 430 and 660 lines each. Business logic, file uploads, scoring algorithms, database queries... all in one giant execute() method. The usual advice? "Just extract services." But I've seen that go wrong too many times. You end up with 20 tiny services that are harder to follow than the original god class. So before touching any code, I built a checklist. 𝗙𝗶𝘃𝗲 𝗾𝘂𝗲𝘀𝘁𝗶𝗼𝗻𝘀. If a block of code doesn't pass at least three, it stays where it is. → Cohesion: can you circle methods that only talk to each other? → Dependencies: does this block use different deps than the rest? → Reuse: can you name another use case that needs this logic today? → Testability: would extracting this cut your mock count in half? → Orchestrator: after extraction, does execute() read like a recipe? The safe move: composition-via-constructor. The use case builds extracted services from its existing dependencies. Zero wiring changes. No DI config updates. Ship without fear. Six weeks later, same audit: B+ (82/100). A 339-point swing. Not because of magic. Because of a repeatable decision filter that kept us from extracting the wrong things. I turned this into a full article covering the five questions, three real extraction examples, what NOT to extract, and the safe extraction pattern. Link in comments 👇
