Skill
find-duplicate-ownership
Find duplicate ownership, hidden second sources of truth, and contract drift in layered codebases. Use when reviewing normalization, validation, defaulting, canonicalization, persistence mapping, runtime-vs-durable state, duplicated helpers, query or cache ownership, or any "who owns this rule?" architecture question. Especially useful for SSOT audits across frontend, backend, shared core, and adapter layers, and when the user explicitly asks for duplicate-ownership exploration with subagents.
