Goal

Detect and report structural duplication across modules (not copy/paste), especially where:

• different domain concepts remain correctly separate, but
• the underlying processing pipeline is parallel/duplicated, risking drift.

When unification likely requires subtle abstraction, produce a staged plan that can be executed safely.

Scope

• This skill does not enforce “thin public facades” or restructure public APIs.
• This skill does identify shared pipeline spines and propose extraction targets and abstraction seams.
