Activates on mentions of implement, build this, code this, start coding, fix this bug, refactor, make changes, develop this feature, implementation plan, coding task, write the code, or start building.
Use this skill when writing code, implementing features, refactoring, planning architecture, designing systems, reviewing code, or debugging. This skill transforms junior-level code into senior-engineer quality software through SOLID principles, TDD, clean code practices, and professional software design.
Comprehensive code review covering security vulnerabilities, performance bottlenecks, best practices, and refactoring opportunities. Use when user requests code review, security audit, or performance analysis.
React performance optimization and best practices. Use when writing React components, hooks, or JSX; refactoring React code; optimizing re-renders, memoization, or state management; reviewing React code for performance issues; fixing hydration mismatches; or implementing transitions, lazy initialization, or effect dependencies. Covers React 19+ features including useEffectEvent, Activity component, and ref props.
Guides the design and structuring of workflow-based Claude Code skills with multi-step phases, decision trees, subagent delegation, and progressive disclosure.

Use when writing, reviewing, or refactoring code. Apply when naming variables or functions, structuring classes, handling errors, writing tests, or when code feels complex or hard to understand. Based on Robert C. Martin's Clean Code.
Clean Code principles, professional practices, and workflows for TypeScript developers. Based on Robert C. Martin's "Clean Code" and "The Clean Coder" books. IMPORTANT: When this skill is active, always load and consult the reference files (rules.md, examples.md) before giving advice or writing code. Reference content takes precedence over general knowledge. Use this skill when: - Writing TypeScript/JavaScript code - Reviewing code or pull requests - Refactoring existing code - Following test-driven development (TDD) - Fixing bugs with proper test coverage - Planning test strategy for features - Estimating tasks accurately - Handling deadlines and commitments professionally - Working effectively with teams
Use when Code implementation and refactoring, architecturing or designing systems, process and workflow improvements, error handling and validation. Provide tehniquest to avoid over-engineering and apply iterative improvements.

Systematic codebase quality scan for identifying duplication, redundancy, and improvement opportunities. Use when reviewing a repo's architecture, finding refactoring targets, or assessing code health. Triggers: "scan the repo", "find code duplication", "suggest improvements", "code quality review", "is there redundant code", "refactoring plan", "architecture review".
