Skill UI

Reference document for monopoly scale-benchmarks. Provides quick formulas for converting DAU to RPS, storage and bandwidth estimation, known scale limits of common technologies (databases, queues, caching), capacity planning by user scale (1K to 10M DAU), SLO targets, and latency budget guidelines. Useful for system design, capacity planning, and architecture decisions.

Creates language-specific variants of existing Semgrep rules. Use when porting a rule to target languages, with applicability analysis and test-driven validation for each language.

This specialized skill guides users through a structured, forensic investigation process when facing sudden, significant drops in organic traffic or search rankings. It is designed for incident scenarios—such as suspected penalties, Core Updates, major technical regressions, or unexplained traffic crashes—providing a systematic approach to triage, root-cause analysis, and developing a prioritized recovery plan.

This guide details the principles and implementation techniques for Skeuomorphism—the design style that makes digital interfaces resemble real-world physical objects. It covers core principles like realistic textures (wood, leather), physical lighting, depth, and real-world metaphors. Provides detailed code examples for Web (CSS), iOS (SwiftUI), and Android (Flutter) to achieve highly realistic, tactile UI elements.

This skill provides comprehensive diagnosis and optimization for agent skill libraries. By analyzing historical session transcripts from platforms like Claude Code and Codex, alongside static skill file checks, it scores each skill across 8 dimensions. It identifies issues such as low trigger rates, poor post-invocation user reaction, and incomplete workflow execution, generating a prioritized report (P0/P1/P2) to significantly improve the agent's overall performance and reliability.

This powerful orchestrator coordinates content across Instagram, Telegram, and WhatsApp. It automatically adapts central content into platform-specific formats (captions, templates, hashtags), ensuring brand consistency. Features include unified analytics, synchronized scheduling, and centralized campaign management, maximizing reach and operational efficiency across all major channels.

A comprehensive guide for implementing soft pastel, low-contrast aesthetics across web, iOS (SwiftUI), and Flutter applications. Details include desaturated color palettes (mint, blush, lavender), rounded corner principles, airy spacing techniques, and specific CSS/SwiftUI code examples for achieving a calming, gentle user interface suitable for lifestyle or baby-related branding.

This skill provides guidance for quality-focused software development and architecture based on Clean Architecture and Domain Driven Design principles. It covers code style rules, best practices like library-first approach, naming conventions, separation of concerns, and avoiding anti-patterns to ensure maintainable and scalable code.

Optimize Apache Spark jobs with partitioning, caching, shuffle optimization, and memory tuning. Covers execution model, performance factors, and practical patterns for improving job speed and scalability.

This skill provides a structured approach to systematically identify security threats by applying the STRIDE methodology (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege). It is crucial for conducting thorough threat modeling sessions, analyzing system architectures, reviewing security design decisions, and creating robust security documentation for compliance and auditing purposes.

This skill enables comprehensive software supply chain security assessment, covering SBOM generation, SCA scanning, CI/CD pipeline review, and container image auditing. It involves verifying build integrity, dependency provenance, and vulnerability reachability. Key activities include auditing upstream repositories, integrating security gates in CI/CD, ensuring artifact integrity, and monitoring CVEs for actual exploitability to mitigate supply chain attacks.

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.
