Claude Skills

Use PROACTIVELY when working on multiple branches simultaneously or creating parallel Claude Code sessions. Automates git worktree creation with prerequisite checking, development environment initialization, and safe cleanup. Supports single worktree, batch creation, and worktree removal. Not for non-git projects or branch management without worktrees.

Use PROACTIVELY when user needs to create a new GitHub repository or set up a project with best practices. Automates repository creation with four modes - quick public repos (~30s), enterprise-grade with security and CI/CD (~120s), open-source community standards (~90s), and private team collaboration with governance (~90s). Not for existing repo configuration or GitHub Actions workflow debugging.

Use PROACTIVELY when setting up OpenTelemetry monitoring for Claude Code usage tracking, cost analysis, or productivity metrics. Provides local PoC mode (full Docker stack with Grafana) and enterprise mode (centralized infrastructure). Configures telemetry collection, imports dashboards, and verifies data flow. Not for non-Claude telemetry or custom metric definitions.

Use PROACTIVELY when creating new React projects requiring modern tooling and best practices. Provides three modes - sandbox (Vite + React for quick experiments), enterprise (Next.js with testing and CI/CD), and mobile (Expo + React Native). Enforces TypeScript strict mode, Testing Trophy approach, and 80% coverage. Not for non-React projects or modifying existing applications.

Test-driven debugging for failing tests or bugs

Defines, documents, and deploys a consistent and authentic brand voice. Use when harmonizing brand voice across all customer touchpoints, building trust, or differentiating from competitors.

A comprehensive skill for A/B split test engineering, following Neil Patel's methodology. It covers test prioritization (ICE scoring), statistical significance, sample size, hypothesis formation, variable isolation, multivariate vs. A/B decisions, test documentation, and conversion lift calculation. Use this skill to optimize web pages, ads, and emails for higher conversion rates.

Test-driven development for Spring Boot using JUnit 5, Mockito, MockMvc, Testcontainers, and JaCoCo. Use when adding features, fixing bugs, or refactoring.

Backend architecture patterns, API design, database optimization, and server-side best practices for Node.js, Express, and Next.js API routes.

ClickHouse database patterns, query optimization, analytics, and data engineering best practices for high-performance analytical workloads.

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.

Use when implementation is complete, all tests pass, and you need to integrate the work - validates, updates docs, and creates PR

Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation

Execute implementation tasks with quality and awareness. Use when: (1) After TASKS phase in 5D-SDD workflow, (2) Tasks are defined and sequenced, (3) User is ready to write code, (4) User asks to 'implement,' 'build,' or 'code' a task. This phase produces working code while maintaining connection to spec intent.

Analyze the gap between current state and specification to identify all required changes. Use when: (1) After SPEC phase in 5D-SDD workflow, (2) Spec exists and implementation is about to begin, (3) User asks 'what needs to change' or 'what's the delta,' (4) Assessing scope of work. This phase prevents surprise discoveries during implementation.
