Rails Engine Extraction
Use this skill when the task is to move existing code out of a Rails app and into an engine.
Prefer incremental extraction over big-bang rewrites. Preserve behavior first, then improve design.
HARD-GATE
DO NOT extract and change behavior in the same step. Extraction must preserve existing behavior; refactoring and improvements belong in a separate step after the move is complete and verified.
