 Skills for code, architecture, APIs, and design decisions, with an emphasis on correctness and simplicity.
 
 - **[antimatter-code-quality-review](./skills/engineering/antimatter-code-quality-review/SKILL.md)** — Total annihilation: no finding survives unless it survives refutation. Inspired by Cursor's [Thermo-Nuclear review](https://github.com/cursor/plugins/blob/main/cursor-team-kit/skills/thermo-nuclear-code-quality-review/SKILL.md), [Matt Pocock's skills](https://github.com/mattpocock/skills), and correctness-first design philosophy; pins the diff frame, checks intent and repo standards, and only reports provable findings.
+- **[antimatter-codebase-structure-review](./skills/engineering/antimatter-codebase-structure-review/SKILL.md)** — Audits hierarchy, naming, ownership, dependency boundaries, and growth readiness; every finding must survive refutation and specify an evidence-backed change.
 - **[pizza1](./skills/engineering/pizza1/SKILL.md)** — Justify by correctness, never by convention. Use when a design is defended by "it's what the codebase does", "the canonical lane does it", ergonomics, churn, transition size, compatibility, legacy paths, or scope.
 - **[readonly](./skills/engineering/readonly/SKILL.md)** — Prove, don't guess. A user-invoked modifier for codebase questions and other skills: exhaust read-only evidence, avoid "likely" answers when facts can be checked, and stop before implementation, issues, commits, or remote changes.
