Skill UI

Guides using the GitHub CLI to inspect repositories, manage PRs/issues/actions, and fetch API data instead of curl/WebFetch, with tips for cloning, viewing, and automating GitHub workflows.

Analyzes CORS configurations via the cors-policy-validator plugin to spot misconfigurations, validate headers or files, and report vulnerabilities so developers can secure web apps and APIs from unsafe cross-origin access.

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.

Implement robust, event-driven workflows for managing GPU resources on Vast.ai. Since native webhooks are unavailable, this skill uses Python polling to continuously monitor instance status changes (e.g., loading, running, exited). It enables complex automation tasks such as auto-recovering from spot preemption, handling lifecycle events, and tracking billing costs.

Configures robust CI/CD pipelines for Vercel projects using GitHub Actions. This guide automates the full deployment lifecycle, including generating preview environments on every pull request, performing reliable production builds upon merging to main, and implementing test gating to ensure code quality before release. Ideal for professional web development workflows.

Deploy projects or websites instantly to Vercel using preview mode, with fallback scripts handling packaging and authentication, and guidance for escalated network access when sandboxing blocks outbound requests.

A comprehensive guide to building and deploying Vercel Edge Functions. These functions run on Vercel's global Edge Network (V8 isolates), providing ultra-low latency and zero cold starts. Learn how to use Web Standard APIs for critical tasks such as authentication, geolocation routing, A/B testing, and high-performance API middleware, drastically improving application speed and user experience.

A comprehensive guide to optimizing Vercel deployment performance. This skill covers advanced techniques such as edge caching implementation (using Cache-Control headers), leveraging Incremental Static Regeneration (ISR), minimizing serverless function cold starts, and optimizing bundle size. Use this when facing slow page load times, needing to improve Core Web Vitals, or requiring robust, scalable deployment performance.

A comprehensive guide for implementing secure and reliable webhook endpoints to handle Vercel deployment lifecycle events. This skill covers signature verification (HMAC) to ensure security, processing key events (e.g., deployment.ready, deployment.error), and implementing idempotency to prevent duplicate actions. Ideal for building automated CI/CD integrations, status notifications, or custom project hooks that react to deployment changes in real-time.

Guides frontend developers through generating Vue components, offering best-practice patterns, production-ready code, and validation for accessibility and performance.

Automates Web Application Firewall rule creation by guiding advanced security teams through best practices, code generation, and validation for compliant penetration-testing workflows.

A comprehensive guide for auditing web content against WCAG 2.2 guidelines. This skill assists users in conducting thorough accessibility audits by combining automated scans (Axe, Lighthouse) with critical manual checks, such as keyboard navigation and screen reader flow. It provides actionable remediation strategies to ensure compliance with standards like ADA and Section 508.
