Analyze and refactor the provided code to improve its quality, maintainability, and performance. ## Use this skill when - Refactoring tangled or hard-to-maintain code - Reducing duplication, complexity, or code smells - Improving testability and design consistency - Preparing modules for new features safely ## Do not use this skill when - You only need a small one-line fix - Refactoring is prohibited due to change freeze - The request is for documentation only ## Context The user needs help refactoring code to make it cleaner, more maintainable, and aligned with best practices. Focus on practical improvements that enhance code quality without over-engineering. ## Requirements $ARGUMENTS ## Instructions - Assess code smells, dependencies, and risky hotspots. - Propose a refactor plan with incremental steps. - Apply changes in small slices and keep behavior stable. - Update tests and verify regressions. - If detailed patterns are required, open `resources/implementation-playbook.md`. ## Safety - Avoid changing external behavior without explicit approval. - Keep diffs reviewable and ensure tests pass. ## Output Format - Summary of issues and target areas - Refactor plan with ordered steps - Proposed changes and expected impact - Test/verification notes ## Resources - `resources/implementation-play...
