This skill should be used when the user wants to visualize data. It intelligently selects the most suitable chart type from 26 available options, extracts parameters based on detailed specifications, and generates a chart image using a JavaScript script.
Provides comprehensive guidance for generating MyBatis-Plus code including Entity, Mapper, Service, ServiceImpl, Controller, DTO, VO, BO and other related objects from database tables. Use ONLY when the user explicitly mentions MyBatis-Plus, mybatis-plus-generator, or wants to generate code using MyBatis-Plus framework. This skill automatically generates standard CRUD methods and custom methods based on user requirements for MyBatis-Plus projects. Supports MVC and DDD architectures, Java and Kotlin languages. Do NOT trigger for generic code generation, JPA/Hibernate, or other ORM frameworks.
TypeScript and JavaScript expert with deep knowledge of type-level programming, performance optimization, monorepo management, migration strategies, and modern tooling. Use PROACTIVELY for any TypeScript/JavaScript issues including complex type gymnastics, build performance, debugging, and architectural decisions. If a specialized expert is a better fit, I will recommend switching and stop.
Motion animation library for JavaScript, React and Vue. Use when creating animations, gestures, layout transitions, scroll-linked effects, or working with motion values and animation controls.
Valtio proxy state management for React and vanilla JavaScript. Use when creating reactive state, managing application state, or working with proxy-based state management.
Development conventions and patterns for everything-claude-code. JavaScript project with conventional commits.
Debug client-side issues using browser developer tools. Identify JavaScript errors, styling issues, and performance problems in the browser.
Systematic JavaScript/TypeScript performance audit and optimization using V8 profiling and runtime patterns. Use when (1) Users say 'optimize performance', 'audit performance', 'this is slow', 'reduce allocations', 'improve speed', 'check performance', (2) Analyzing code for performance anti-patterns (O(n²) complexity, excessive allocations, I/O blocking, template literal waste), (3) Optimizing functions regardless of current usage context - utilities, formatters, parsers are often called in hot paths even when they appear simple, (4) Fixing V8 deoptimization (monomorphic/polymorphic issues, inline caching). Audits ALL code for anti-patterns and reports findings with expected gains. Covers loops, caching, batching, memory locality, algorithmic complexity fixes with ❌/✅ patterns.
Comprehensive TypeScript/JavaScript coding standards focusing on type safety, defensive programming, and code correctness. Use when (1) Writing or reviewing TS/JS code, (2) Fixing type errors or avoiding any/enum/null, (3) Implementing control flow, state management, or error handling, (4) Applying zero-value pattern or immutability, (5) Code review for TypeScript anti-patterns. Covers naming conventions, function design, return values, bounded iteration, input validation. For performance optimization, use accelint-ts-performance skill. For documentation, use accelint-ts-documentation skill.
Comprehensive security audit and vulnerability detection for JavaScript/TypeScript applications following OWASP Top 10. Use when (1) Users say 'audit security', 'check for vulnerabilities', 'security review', 'implement authentication', 'secure this code', (2) Adding authentication, API endpoints, file uploads, or handling user input, (3) Working with secrets, credentials, or sensitive data, (4) Implementing payment features or blockchain integrations, (5) Conducting pre-deployment security checks. Audits for: hardcoded secrets, injection vulnerabilities, XSS/CSRF, broken access control, insecure authentication, rate limiting, dependency vulnerabilities, sensitive data exposure.
Guide for migrating a project from ESLint to Oxlint. Use when asked to migrate, convert, or switch a JavaScript/TypeScript project's linter from ESLint to Oxlint.
Build declarative AI Services with LangChain4j using interface-based patterns, annotations, memory management, tools integration, and advanced application patterns. Use when implementing type-safe AI-powered features with minimal boilerplate code in Java applications.
