Lightweight design smell review for modules and APIs—coupling, cohesion, naming, boundaries, and unnecessary complexity. Use before large refactors or when code feels hard to change. Complements gstack/review (diff-focused).
インストールする前に、エージェントに与えられる指示の中身を確認できます。
Review structure and boundaries, not line-by-line style. Pair with PR diff review for changes; use this for module-level health.
| Smell | Signal | Direction |
|---|---|---|
| God module | Many unrelated responsibilities | Split by domain |
| Shotgun surgery | One change touches many files | Consolidate logic |
| Feature envy | Module A mostly uses B's data | Move behavior |
| Leaky abstraction | Impl details escape API | Narrow public surface |
| Config soup | Magic strings everywhere | Named constants / schema |
| Boolean flags | if is_x branches everywhere | Polymorphism or strategy |
## Summary

概要と使いどころ
"Implement and select ad bidding strategies from manual CPC to automated target-CPA and target-ROAS. Use this skill when the user needs to choose a bidding strategy, set up automated bidding, or optimize bid parameters — even if they say 'what bidding strategy should I use', 'target CPA setup', or 'smart bidding configuration'.".

"Implement VCG mechanism for incentive-compatible ad slot allocation with truthful bidding. Use this skill when the user needs to design a truthful auction mechanism, compute externality-based payments, or understand why platforms may prefer GSP over VCG — even if they say 'truthful auction design', 'VCG payments', or 'incentive-compatible mechanism'.".
