Skill UI

This skill provides a comprehensive guide for writing effective, blameless postmortems. It helps teams conduct post-incident reviews, identify root causes, and prevent recurrence. Ideal for DevOps, engineering, and organizational learning contexts. Includes templates, timelines, and best practices for fostering a blameless culture.

This skill runs a read-only audit to assess production deployment readiness. It reviews release artifacts, migration changes, configuration gaps, and potential risks (including rollback feasibility and launch blockers) before actual deployment or merging. It helps reduce coordination failures and ensures a safe release cycle.

Govern evidence-backed canonical project state across sessions, branches, reviews, and research cycles. Maintains authoritative status, decisions, constraints, and negative evidence so any agent resuming work can verify claims, avoid repeated failures, and know the next step.

This skill reviews git diffs or specific file scopes for code reuse, quality, efficiency, clarity, and standards compliance. It optionally applies safe, behavior-preserving fixes. It uses parallel read-only sub-agents to inspect code while the main agent applies changes. Suitable for auditing changes, simplifying code, or refactoring.

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 generates optimized title tags, meta descriptions, Open Graph tags, and Twitter Card tags for web pages. It aligns content with search intent and conversion goals using CTR frameworks. Users provide page details like keywords and audience, and the skill outputs SERP previews and multiple title variants for A/B testing to improve click-through rates.

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.
