Probe a site's authentication flow for redirect leaks, missing CSRF, weak session cookies, and OAuth misconfiguration; produces an auth findings.md
Framework-agnostic frontend security guide based on OWASP Secure Coding Practices. Covers XSS prevention, CSRF protection, Content Security Policy (CSP), secure cookie configuration, client-side authentication patterns, input validation, secure storage, and security headers. Activates for security audits, vulnerability reviews, or browser security questions in any web application. NOT for backend/NestJS security (use generating-nest-servers). NOT for Nuxt-specific implementation (use developing-lt-frontend).
Audit frontend codebases for security vulnerabilities and bad practices. Use when performing security reviews, auditing code for XSS/CSRF/DOM vulnerabilities, checking Content Security Policy configurations, validating input handling, reviewing file upload security, or examining Node.js/NPM dependencies. Target frameworks include web platform (vanilla HTML/CSS/JS), React, Astro, Twig templates, Node.js, and Bun. Based on OWASP security guidelines.
Django security best practices, authentication, authorization, CSRF protection, SQL injection prevention, XSS prevention, and secure deployment configurations.
Spring Security best practices for authn/authz, validation, CSRF, secrets, headers, rate limiting, and dependency security in Java Spring Boot services.
Implements secure authentication patterns including login/registration, session management, JWT tokens, password hashing, cookie settings, and CSRF protection. Provides auth routes, middleware, security configurations, and threat model documentation. Use when building "authentication", "login system", "JWT auth", or "session management".
Use this skill when securing web applications, preventing OWASP Top 10 vulnerabilities, implementing input validation, or designing authentication. Triggers on XSS, SQL injection, CSRF, SSRF, broken authentication, security headers, input validation, output encoding, OWASP, and any task requiring application security hardening.
Use when you need to design, review, or improve security in Spring Boot applications — including SecurityFilterChain, OAuth2/JWT resource server patterns, form login basics, method security (@PreAuthorize), CSRF and CORS for APIs, session fixation, security headers, exception handling, password encoding, and sensitive-data-safe logging. This should trigger for requests such as Add Spring Boot security support; Review Spring Boot security configuration; Improve API authorization in Spring Boot; Add JWT resource server security in Spring Boot; Harden Spring Boot security headers and CSRF settings.

Security audit tool for CodeIgniter framework. Conducts white-box static audits on CodeIgniter's mechanisms such as CSRF, XSS output filtering, database query construction, routing and validator configuration, session Cookie security, etc., and maps them to a common vulnerability type system (CSRF/AUTH/XSS/SQL/CFG/SESS, etc.).
Security patterns for web forms including autocomplete attributes for password managers, CSRF protection, XSS prevention, and input sanitization. Use when implementing authentication forms, payment forms, or any form handling sensitive data.
Yida Platform Login State Management Skill, manages login state via Playwright (Cookie Persistence + QR Code Login) and retrieves CSRF Token.
Implement secure session management systems with JWT tokens, session storage, token refresh, logout handling, and CSRF protection. Use when managing user authentication state, handling token lifecycle, and securing sessions.
