Testing WebSocket API Security Flaws

testing-websocket-api-security

mukul975/Anthropic-Cybersecurity-Skills

A comprehensive guide and code suite for performing penetration testing on real-time WebSocket APIs (WS/WSS). This tool assesses vulnerabilities including Cross-Site WebSocket Hijacking (CSWSH), missing handshake authentication, message injection, input validation failures, and DoS risks. It guides users through analyzing the handshake process and testing authorization enforcement using Python and specialized tools.

Security Pen Testing

security-pen-testing

alirezarezvani/claude-skills

Provides offensive security testing methodology, tooling guidance, and workflows for scanning web apps, APIs, dependencies, secrets, and infrastructure to uncover vulnerabilities before attackers exploit them.

Playwright E2E Workflow

sickn33/antigravity-awesome-skills

Coordinated end-to-end testing workflow that leverages Playwright for browser automation, visual regression comparisons, cross-browser coverage, and CI/CD integration so teams can validate web apps before release.

Automated Browser QA and Visual Testing

affaan-m/everything-claude-code

Automates comprehensive end-to-end Quality Assurance (QA) for deployed web applications. This skill performs multi-stage testing, including smoke tests, complex user interactions (forms, authentication), visual regression checks across breakpoints, performance monitoring (Core Web Vitals), and WCAG accessibility audits.

C# .NET Comprehensive Testing Patterns

affaan-m/everything-claude-code

This guide provides comprehensive testing patterns for C# and .NET applications. It covers best practices using xUnit, FluentAssertions, and advanced techniques like mocking (NSubstitute/Moq), parameterized testing, and full integration testing using Testcontainers and WebApplicationFactory. Ideal for improving test quality, coverage, and developing robust, maintainable codebases.

Browser Testing With DevTools MCP

browser-testing-with-devtools

addyosmani/agent-skills

This tool enables deep inspection and validation of web applications by connecting to the browser's DevTools Protocol (MCP). It allows agents to perform tasks like DOM inspection, capturing console logs, monitoring network requests, profiling performance, and taking screenshots in a live environment. Essential for debugging UIs, validating API integrations, and performing end-to-end automated testing.

Flutter E2E Testing with Patrol Framework

patrol-e2e-testing

evanca/flutter-ai-rules

This skill guides the use of Patrol for writing robust End-to-End (E2E) and integration tests in Flutter. It is essential for validating complex user flows, interactions with native APIs (like permissions or deep links), and ensuring cross-platform consistency across Android, iOS, and Web. It helps capture UI regressions and validates the entire application state.

Pentest Command Reference

pentest-commands

zebbern/claude-code-guide

Provides quick reference to penetration testing commands for network scanning, exploitation, password cracking, and web testing workflows, helping security professionals run tools like Nmap, Metasploit, Nikto, and SQLMap during assessments.

Automating Form Filling with Playwright

playwright-automation-fill-in-form

github/awesome-copilot

This skill demonstrates how to use Playwright MCP to programmatically automate the process of inputting data into a web form. It covers various input types, including text fields, date selection, time setting, and file uploads. The process simulates realistic user interaction for data entry or form submission testing, emphasizing the ability to fill data without final submission for review purposes.

Playwright Web Browser Automation Tool

playwright-skill

sickn33/antigravity-awesome-skills

A general-purpose skill for writing and executing end-to-end (E2E) browser automation tests using Playwright. It handles complex scenarios such as login flows, form submission, responsive viewport testing, and checking for broken links. The skill automatically detects local development servers and executes custom scripts in a safe, temporary directory, providing real-time debugging and results visualization.

AI-Powered Web Application Testing

github/awesome-copilot

Leverage AI-powered exploratory testing to thoroughly audit web applications and verify functionality. This skill simulates user interaction, detecting complex bugs, validating critical flows (like checkout or login), and checking accessibility compliance. Use it proactively after development to ensure quality before deployment.

Browser Automation and DevTools Inspection

chrome-devtools

github/awesome-copilot

This skill provides expert-level control over a live Chrome browser. It enables full web automation (clicking, form filling, navigation), deep debugging (analyzing console logs, network requests), visual inspection (screenshots, snapshots), and detailed performance profiling. Ideal for QA engineers, web scraping, and front-end development testing.
