Agent skill
refactor-structural-duplication
Identify structurally duplicate logic (pipeline-spine duplication) across semantically distinct modules. Use when multiple implementations share the same orchestration skeleton (e.g., bounds→shape→chunking→reduction→wrap), and unification may require subtle abstraction. Produces a duplication map and a safe extraction/refactor plan.

Instructions
Read all references in references/ before starting.
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.
Signals
Activate when any of the following are true:
- Multiple modules implement similar orchestration stages (even with different operators).
- There are parallel implementations of structurally similar functionality in the codebase.
- The agent (or a developer) is about to re-implement “the same infrastructure again” for a new product.
Procedure
Follow references/03_PROCEDURE.md.
Output
Produce a single Markdown report using references/05_OUTPUT_TEMPLATE.md.
If abstraction is needed, include a staged plan using references/04_REFACTOR_PLAN_TEMPLATE.md.
