February 2026 (2026-02) focused on delivering automated code quality governance for toss/frontend-fundamentals. Key deliverable: Claude Code Plugin for Automated Code Quality Reviews, emphasizing readability, predictability, cohesion, and coupling. Established a TDD-style evaluation infrastructure with seeded tasks, graders, and run-eval protocol; added realistic business-domain evaluation tasks and production-grade evaluation scenarios. Replaced a generic code-quality skill with four specific skills and updated documentation and examples to align with business language. Expanded reviewer tooling and workflows, including reviewer agent improvements, commands, and run-eval docs. Comprehensive documentation overhaul (README modernization, installation simplifications, usage patterns, and consistency with frontend-fundamentals style). Cost and efficiency improvements through Haiku model usage with token efficiency gains reported (20-35%). Overall, strengthened code quality governance, developer onboarding, and scalable evaluation at scale.
