This Claude Skill provides systematic code review checklists and pre-commit quality gates for evaluating pull requests and code quality. It offers categorized checklists (functionality, design, quality, readability) and a standardized comment prefix system to classify feedback severity. Use it when reviewing PRs or before committing code to enforce consistent quality standards.

This skill ensures evidence-based AI responses by requiring explicit certainty tags and source citations when analyzing code or making recommendations. It prevents hallucinations by distinguishing confirmed facts from inferences and assumptions. Use it during code analysis, suggestion generation, or whenever confidence level needs clarification.

This skill automatically sets up visual regression testing for Storybook projects with Chromatic, Percy, or BackstopJS. It detects your existing configuration and generates the necessary stories, config files, and CI/CD workflows. Use it when you need to add or configure visual testing by triggering phrases like "set up visual regression" or "add Chromatic tests."

The nav-onboard skill provides an interactive, hands-on tutorial for learning Navigator by completing actual tasks. It auto-invokes when users ask for onboarding help with phrases like "teach me Navigator" or "how do I use Navigator." The skill focuses on practical workflows rather than documentation and includes completion tracking to avoid redundant invocations.

This skill helps developers implement Extreme Programming practices like TDD, pair programming, and continuous integration. Use it to improve team collaboration, adopt technical excellence, and establish sustainable agile workflows. It provides actionable guidance on prioritizing and adapting core XP practices for immediate value.

This Claude Skill performs advanced visual regression testing with pixel-perfect and AI-powered diff analysis to detect UI changes. It validates responsive designs across multiple viewports and ensures cross-browser visual consistency. Use it to catch visual regressions, validate design implementations, and maintain UI quality.

This skill provides automated verification and quality assurance for agent outputs, featuring truth scoring, code quality validation, and automatic rollback when scores fall below a 0.95 threshold. It ensures codebase reliability through real-time metrics and statistical analysis. Use it to maintain high-quality outputs in Claude Code projects with integrated CI/CD checks.

This skill provides AI-powered testability assessment for web applications using Playwright and optional Vibium integration. It evaluates applications against 10 principles of intrinsic testability including Observability, Controllability, and Stability. Use it when assessing software testability, identifying improvements, or generating testability reports.

This skill provides advanced test reporting and analytics dashboards for quality engineering metrics, including predictive analytics and trend analysis. It's designed for communicating quality status, tracking trends, and supporting data-driven decisions about software quality. Developers should use it when building automated reports or dashboards that highlight key metrics and actionable insights for teams or executives.

This Claude Skill manages test infrastructure using infrastructure as code, Docker/Kubernetes for consistent environments, and service virtualization. It helps developers ensure environment parity with production and optimize testing costs through auto-shutdown and spot instances. Use it when provisioning test environments or managing testing infrastructure.

This Claude Skill provides systematic test design techniques including boundary value analysis, equivalence partitioning, and decision tables. It helps developers create comprehensive test cases while reducing redundancy through methods like pairwise testing. Use it when designing tests for complex business rules, stateful behavior, or ensuring systematic coverage.

This skill helps developers generate and manage synthetic test data while ensuring privacy compliance. It provides strategies for creating realistic data at scale, anonymizing PII, and maintaining GDPR/CCPA compliance. Use it when building test datasets, handling sensitive information, or needing isolated data for different testing scenarios.

This Claude Skill helps developers design and implement effective test automation frameworks by applying the test pyramid, F.I.R.S.T. principles, and design patterns like Page Object Model. It focuses on integrating automation into CI/CD for fast feedback and improved test efficiency. Use it when building new automation strategies or optimizing existing test suites.

This Claude Skill helps developers create clear, engaging technical content like blog posts, documentation, and tutorials by providing structured guidance and best practices. It emphasizes leading with value, using concrete examples, and maintaining a scannable structure. Use it whenever you need to write or improve technical articles based on real experience.

This skill helps developers apply London (mock-based) and Chicago (state-based) TDD approaches when practicing test-driven development. It guides style selection based on code type—using Chicago for domain logic and London for external dependencies—and provides structured support through the Red-Green-Refactor cycle. Key capabilities include generating, implementing, and refactoring tests with optimized agents for each phase.

Swarm Orchestration enables developers to coordinate multi-agent AI systems for parallel task execution using dynamic topologies like mesh or hierarchical structures. It's ideal for scaling complex workflows beyond single agents, featuring automatic task distribution, load balancing, and fault tolerance. Use this skill when building distributed AI systems that require intelligent coordination between specialized agents.

This skill provides advanced swarm orchestration patterns for complex distributed workflows like research, development, and testing. It enables developers to coordinate multiple specialized agents using both MCP tools and CLI commands for parallel task execution. Use it when you need to manage sophisticated multi-agent systems with mesh topologies and coordinated workflows.

Stream-Chain enables multi-agent workflows where each agent's output streams directly into the next, supporting both custom sequences and predefined pipelines. It's ideal for complex data transformations and sequential processing tasks in Claude Code. The skill maintains full output context between steps for sophisticated coordination.

The SPARC methodology provides a systematic, multi-agent framework for comprehensive software development. It structures projects through five phases—Specification, Pseudocode, Architecture, Refinement, and Completion—with 17 specialized modes. Developers should use this skill when they need an orchestrated, end-to-end workflow from initial research to deployment and monitoring.

This Claude Skill helps developers create properly structured Claude Code Skills with correct YAML frontmatter and progressive disclosure architecture. It generates complete skill templates and directory organization for custom workflows. Use it when building skills that Claude can autonomously discover across all platforms.
