A comprehensive guide detailing security best practices for building and deploying applications on the Replit platform. Learn how to properly manage sensitive data using Replit Secrets (AES-256 encryption), implement secure service-to-service authentication via REPL_IDENTITY tokens, validate custom headers, and prevent common vulnerabilities like hardcoded API keys and SQL injection. Essential for auditing and securing production environments.

Provides authentication, authorization, encryption, secrets, and hardening patterns for designing secure auth flows, managing tokens, configuring CORS, and implementing best practices around API keys, JWT, OAuth, and rate limiting.

This comprehensive guide details how to harden Sentry's security posture and ensure compliance with regulations like GDPR. It covers best practices for managing sensitive data, implementing PII scrubbing, and configuring `beforeSend` hooks to automatically redact sensitive information such as passwords, API keys, tokens, IP addresses, and emails from client-side and server-side events.

This skill guides the creation of production-ready design systems using Tailwind CSS. It covers advanced topics such as implementing design tokens, managing component variants, establishing responsive patterns, and ensuring high accessibility standards. Use this when building component libraries, applying theming, or standardizing UI patterns across a large codebase.

A comprehensive guide to modern utility-first CSS using Tailwind CSS v4 principles. Covers the shift to CSS-first configuration, utilizing CSS variables for design tokens, implementing advanced container queries, and mastering responsive, dark mode, and complex layout patterns (Grid/Flex). Essential for building modern, component-driven UIs efficiently.

Automates Composio Textit workflows through Rube MCP APIs, guiding you to search tool schemas, manage Textit connections, and execute operations while reusing sessions, filling memory placeholders, and respecting pagination tokens.

This skill scans web application endpoints and cookies to spot missing CSRF safeguards—tokens, double-submit cookies, SameSite attributes, and origin checks—then documents vulnerable paths and mitigation steps for security reviews.

This skill guides developers through installing the Vercel Command Line Interface (CLI) and configuring secure authentication. It covers multiple setup scenarios, including interactive OAuth login, setting environment tokens for CI/CD pipelines, and linking a local project directory to a specific Vercel project. Essential for initial project setup and ensuring smooth deployments.

This skill guides users through implementing comprehensive security measures for Vercel deployments. It covers best practices for secret management (using sensitive environment variables), configuring critical HTTP security headers (such as CSP and HSTS), protecting preview environments, and enforcing robust access control for API routes and deployment tokens.

Guides analysts through assessing web authentication, credential stuffing, password policies, session tokens, and fixation flows to uncover broken authentication risks before attackers do.

A comprehensive guide for implementing reliable and resilient network communication in modern applications. Covers best practices for API requests, utilizing libraries like React Query/SWR for advanced data fetching, implementing robust error handling with retries and exponential backoff, managing authentication tokens, and ensuring offline-first support across various environments (including Expo Router loaders).
