Skill UI

This specialized skill reviews user interface animations, motion patterns, and interactive code (CSS, Framer Motion, etc.) against a strict, high-craft standard. It evaluates not only functionality but also performance, accessibility, physical correctness, and adherence to motion design principles. Use it when reviewing diffs related to transitions, keyframes, or gestures to ensure the motion feels right, not just that it runs.

This skill performs Static Application Security Testing (SAST) to detect code vulnerabilities across multiple programming languages and frameworks. It helps identify injection flaws, hardcoded secrets, and security policy violations before deployment. Suitable for code reviews, compliance checks like OWASP, and legacy code assessment. Requires source code access and is not for runtime testing.

This skill reviews code differences (diffs) to identify opportunities for improvement in clarity, reusability, efficiency, and overall quality. It employs multiple specialized sub-agents (e.g., Code Reuse, Efficiency, Quality) to audit changes. It can provide high-confidence, behavior-preserving fixes when requested, ensuring the code adheres to best practices without introducing regressions. Best used when refactoring, cleaning up, or auditing a specific code scope.

This skill helps developers fix social sharing previews, ensuring that URLs render as rich, consistent cards across major platforms like Facebook, LinkedIn, X/Twitter, and WhatsApp. It provides standardized implementation for Open Graph (OG) tags and Twitter cards, crucial for improving SEO and discoverability.

This skill covers comprehensive software supply chain security assessments, including SBOM generation, SCA scanning, CI/CD pipeline reviews, and container image audits. It focuses on verifying build integrity, dependency provenance, and vulnerability reachability to ensure secure software delivery and mitigate supply chain risks.

This expert reviews and rectifies complex Swift Concurrency issues, such as actor isolation violations, Sendable safety breaches, and data races. It applies modern patterns (like `@MainActor` and `actor` usage) to ensure code adheres to Swift 6.2+ standards while minimizing behavior changes. Use it when debugging concurrency warnings or migrating legacy codebases.

This skill reviews generated or changed test code against universal testing rules before deployment. It prevents common failure modes like mock-heavy unit tests, near-duplicate test bodies, and tests that re-verify the framework. It enforces best practices such as testing behavior over implementation, justifying mocks at system boundaries, and ensuring every test has a clear justification. Use it when reviewing diffs, new test files, or when writing new tests to ensure high-quality, maintainable test suites.

This skill specializes in threat modeling methodologies like STRIDE and PASTA for security architecture reviews and risk assessment. It helps identify attack vectors, prioritize security risks, and design mitigation strategies to build secure-by-design systems. Ideal for security audits and system design phases.

This skill reviews UI code for design system compliance, accessibility standards, and best practices. It checks for hardcoded values, component conventions, mobile responsiveness, performance optimization, typography consistency, and visual coherence. It ensures code aligns with established design tokens and accessibility guidelines like WCAG.

Aggregates Uncle Bob’s Clean Code, Architecture, Coder, Agile, and design-pattern guidance to evaluate reviews, refactors, and architecture decisions, and to surface professionalism heuristics without replacing your linter or formatter.

Vibers provides a human-in-the-loop code review workflow for AI-generated GitHub projects. Users push code, and the service reviews it against a specification, checks for security issues, and submits a pull request with suggested fixes. It supports various languages and requires adding a collaborator and configuring a GitHub Action to trigger the review process.

This skill fetches the latest writing guidelines from a specified source URL and reviews provided files against those rules. It outputs findings in a terse format, ensuring content compliance with established standards. Useful for maintaining consistency in documentation or technical writing workflows within development environments.
