The package manager for agent skills and context

This skill enables Claude to execute visual regression tests using tools like Percy, Chromatic, and BackstopJS. It captures screenshots, compares them against baselines, and analyzes visual differences to identify unintended UI changes. Use this skill when the user requests visual testing, UI change verification, or regression testing for a web application or component. Trigger phrases include "visual test," "UI regression," "check visual changes," or "/visual-test".

This skill uses the test-doubles-generator plugin to automatically create mocks, stubs, spies, and fakes for unit testing. It analyzes dependencies in the code and generates appropriate test doubles based on the chosen testing framework, such as Jest, Sinon, or others. Use this skill when you need to generate test doubles, mocks, stubs, spies, or fakes to isolate units of code during testing. Trigger this skill by requesting test double generation or using the `/gen-doubles` or `/gd` command.

This skill automates security vulnerability testing. It is triggered when the user requests security assessments, penetration tests, or vulnerability scans. The skill covers OWASP Top 10 vulnerabilities, SQL injection, XSS, CSRF, authentication issues, and authorization flaws. Use this skill when the user mentions "security test", "vulnerability scan", "OWASP", "SQL injection", "XSS", "CSRF", "authentication", or "authorization" in the context of application or API testing.

This skill enables Claude to run and manage integration test suites. It automates environment setup, database seeding, service orchestration, and cleanup. Use this skill when the user asks to "run integration tests", "execute integration tests", or any command that implies running integration tests for a project, including specifying particular test suites or options like code coverage. It is triggered by phrases such as "/run-integration", "/rit", or requests mentioning "integration tests". The plugin handles database creation, migrations, seeding, and dependent service management.

This skill enables Claude to generate end-to-end (E2E) tests for web applications. It leverages Playwright, Cypress, or Selenium to automate browser interactions and validate user workflows. Use this skill when the user requests to "create E2E tests", "generate end-to-end tests", or asks for help with "browser-based testing". The skill is particularly useful for testing user registration, login flows, shopping cart functionality, and other multi-step processes within a web application. It supports cross-browser testing and can be used to verify the responsiveness of web applications on different devices.

This skill enables Claude to design and execute chaos engineering experiments to test system resilience. It is used when the user requests help with failure injection, latency simulation, resource exhaustion testing, or resilience validation. The skill is triggered by discussions of chaos experiments (GameDays), failure injection strategies, resilience testing, and validation of recovery mechanisms like circuit breakers and retry logic. It leverages tools like Chaos Mesh, Gremlin, Toxiproxy, and AWS FIS to simulate real-world failures and assess system behavior.

This skill enables cross-browser compatibility testing for web applications using BrowserStack, Selenium Grid, or Playwright. It tests across Chrome, Firefox, Safari, and Edge, identifying browser-specific bugs and ensuring consistent functionality. It is used when a user requests to "test browser compatibility", "run cross-browser tests", or uses the `/browser-test` or `/bt` command to assess web application behavior across different browsers and devices. The skill generates a report detailing compatibility issues and screenshots for visual verification. Activates when you request "conducting browser compatibility tests" functionality.

This skill enables Claude to perform comprehensive accessibility audits. It uses the accessibility-test-scanner plugin to identify WCAG 2.1/2.2 compliance issues, validate ARIA attributes, check keyboard navigation, and assess screen reader compatibility. Use this skill when the user requests an accessibility scan, audit, or compliance check, or when terms like "WCAG", "ARIA", "screen reader", "accessibility testing", or "a11y" are mentioned. It provides actionable insights for improving web application accessibility.

This skill enables Claude to automatically scan for XSS (Cross-Site Scripting) vulnerabilities in code. It is triggered when the user requests to "scan for XSS vulnerabilities", "check for XSS", or uses the command "/xss". The skill identifies reflected, stored, and DOM-based XSS vulnerabilities. It analyzes HTML, JavaScript, CSS, and URL contexts to detect potential exploits and suggests safe proof-of-concept payloads. This skill is best used during code review, security audits, and before deploying web applications to production.

This skill enables comprehensive vulnerability scanning using the vulnerability-scanner plugin. It identifies security vulnerabilities in code, dependencies, and configurations, including CVE detection. Use this skill when the user asks to scan for vulnerabilities, security issues, or CVEs in their project. Trigger phrases include "scan for vulnerabilities", "find security issues", "check for CVEs", "/scan", or "/vuln". The plugin performs static analysis, dependency checking, and configuration analysis to provide a detailed vulnerability report.

This skill enables Claude to detect SQL injection vulnerabilities in code. It uses the sql-injection-detector plugin to analyze codebases, identify potential SQL injection flaws, and provide remediation guidance. Use this skill when the user asks to find SQL injection vulnerabilities, scan for SQL injection, or check code for SQL injection risks. The skill is triggered by phrases like "detect SQL injection", "scan for SQLi", or "check for SQL injection vulnerabilities".

This skill enables Claude to check session security implementations within a codebase. It analyzes session management practices to identify potential vulnerabilities. Use this skill when a user requests to "check session security", "audit session handling", "review session implementation", or asks about "session security best practices" in their code. It helps identify issues like insecure session IDs, lack of proper session expiration, or insufficient protection against session fixation attacks. This skill leverages the session-security-checker plugin. Activates when you request "checking session security" functionality.
