Consistency Check

Detects cross-document inconsistencies by comparing all GDDs against the entity registry (design/registry/entities.yaml). Uses a grep-first approach: reads the registry once, then targets only the GDD sections that mention registered names — no full document reads unless a conflict needs investigation.

This skill is the write-time safety net. It catches what /design-system's per-section checks may have missed and what /review-all-gdds's holistic review catches too late.

When to run:

• After writing each new GDD (before moving to the next system)
• Before /review-all-gdds (so that skill starts with a clean baseline)
• Before /create-architecture (inconsistencies poison downstream ADRs)
• On demand: /consistency-check entity:[name] to check one entity specifically

Output: Conflict report + optional registry corrections
