Use when adding authentication to React Native or Expo mobile apps (iOS/Android) with biometric support - integrates react-native-auth0 SDK with native deep linking
Manage Workers/KV/R2/D1/Hyperdrive via Cloudflare MCP, perform observability/build troubleshooting/audit/container sandbox operations. Triggers: worker/KV/R2/D1/logs/build/deploy/screenshot/audit/sandbox. Three permission tiers: Diagnose (read-only), Change (write requires confirmation), Super Admin (isolated environment). Write operations must follow read-first, user confirmation, post-execution verification.
Create UI wireframes and mockups using drawio XML format with platform-specific UI component libraries. Best for web page layouts, iOS/Android mobile app mockups, and Bootstrap-based designs. Built on drawio with mockup-specific stencils. NOT for simple flowcharts (use mermaid) or data visualization (use vega).
[Frontend] Review UI code for web interface design compliance covering WCAG 2.2/3.0 accessibility, responsive design, performance, usability, and modern best practices. Use when asked to 'review my UI', 'check accessibility', 'audit design', 'review UX', 'check responsive design', or 'check my site against best practices'. Actions: review, check, audit, analyze, validate. Topics: accessibility, WCAG, ARIA, semantic HTML, focus states, forms, animation, typography, content handling, images, performance, Core Web Vitals, navigation, touch interaction, responsive design, mobile-first, dark mode, internationalization, hydration.

Use when working with Chargebee for (1) API integration and REST endpoint calls, (2) Processing webhook events, (3) Customer management operations, (4) Subscription lifecycle handling, (5) Payment and invoice processing, (6) Any other billing-related integration tasks with Chargebee platform.
Creates comprehensive frontend UI/UX designs including user interfaces, design systems, component libraries, responsive layouts, and accessibility implementations. Produces wireframes, mockups, design specifications, and implementation guidelines. Use when designing user interfaces, creating design systems, building component libraries, implementing responsive designs, ensuring accessibility compliance, or when users mention UI design, UX design, interface design, design systems, user experience, or frontend design patterns.
This skill should be used when the user asks to "simplify code", "clean up code", "refactor for clarity", "reduce complexity", "improve readability", "make this easier to maintain", or asks to simplify recently modified code.
Security vulnerability scanning using Trivy for ecommerce project. Scans dependencies, container images, and IaC. Blocks CRITICAL and HIGH severity. Triggers on "trivy", "vulnerability scan", "security scan", "container scan", "cve", "dependency scan", "npm audit", "docker scan", "security check". PROACTIVE: MUST invoke before committing code with new dependencies.
Autonomous agents are AI systems that can independently decompose goals, plan actions, execute tools, and self-correct without constant human guidance. The challenge isn't making them capable - it's making them reliable. Every extra decision multiplies failure probability. This skill covers agent loops (ReAct, Plan-Execute), goal decomposition, reflection patterns, and production reliability. Key insight: compounding error rates kill autonomous agents. A 95% success rate per step drops to 60% b
Performs arbitrary-precision arithmetic calculations including addition, subtraction, multiplication, division, and exponents. Use when the user asks to calculate, compute, or evaluate math expressions, or when precise decimal arithmetic is needed to avoid floating-point errors.
Audit and annotate an AI-generated implementation plan for requirements traceability, YAGNI compliance, and assumption risks. Use when reviewing, validating, or auditing an implementation plan or design proposal produced by an AI agent.
Build on-device AI into React Native apps using ExecuTorch. Provides hooks for LLMs, computer vision, OCR, audio processing, and embeddings without cloud dependencies. Use when building AI features into mobile apps - AI chatbots, image recognition, speech processing, or text search.
