Validates type consistency across Rust, TypeScript, PostgreSQL boundaries. Use when reviewing code, debugging type mismatches, or validating API contracts. Triggers on: check consistency, validate types, find mismatches, cross-language.
Maintain consistent code formatting, naming conventions, type safety, and automated code quality standards across PHP and TypeScript/JavaScript. Use this skill when writing or editing any PHP files (.php), TypeScript/JavaScript files (.ts, .tsx, .js, .jsx), when implementing type declarations and return types, when running code formatters (Laravel Pint, Ultracite) or linters, when running static analysis tools (Larastan), when naming variables, functions, classes, or files, when applying DRY principles, when removing dead code, or when preparing code for review or commit.
Strict TypeScript rules. Use when writing ANY TypeScript.
Run ESLint and TypeScript type checking on the frontend codebase. Use when user mentions "lint", "type check", "check code", "eslint", "tsc", or before committing changes.
Security intelligence for code analysis. Detects SQL injection, XSS, CSRF, authentication issues, crypto failures, and more. Actions: scan, analyze, fix, audit, check, review, secure, validate, sanitize, protect. Languages: JavaScript, TypeScript, Python, PHP, Java, Go, Ruby. Frameworks: Express, Django, Flask, Laravel, Spring, Rails. Vulnerabilities: SQL injection, XSS, CSRF, authentication bypass, authorization issues, command injection, path traversal, insecure deserialization, weak crypto, sensitive data exposure. Topics: input validation, output encoding, parameterized queries, password hashing, session management, CORS, CSP, security headers, rate limiting, dependency scanning.

Drizzle ORM for TypeScript - type-safe SQL queries, schema definitions, migrations, and relations. Use when: building database layers in TypeScript applications.
Advanced TypeScript type system patterns for production codebases. [What: branded types for nominal typing, discriminated unions, template literal types, conditional types, the infer keyword, satisfies operator, const assertions, Zod schema inference, type-safe event emitters, exhaustive switch checking] [When: designing domain models, building type-safe APIs, creating reusable generic utilities, eliminating runtime bugs with compile-time guarantees, refactoring any-typed codebases] [Keywords: branded types, discriminated union, template literal types, conditional types, infer, satisfies, const assertion, Zod inference, exhaustive, mapped types, utility types, nominal typing, type narrowing, generic constraints] NOT for basic TypeScript syntax or React component typing (use a React-specific skill).
Frontend testing rules with Vitest, React Testing Library, and MSW. Includes coverage requirements, test design principles, and quality criteria. Use when writing frontend tests or reviewing test quality.
Expert in Claude Agent SDK development. Use when users ask about SDK API, agent configuration, MCP servers, hooks, permissions, file checkpointing, or when they mention @AGENT_SDK_DOCS.md. Provides accurate API reference, code examples with TypeScript types, and best practices.
Builds the Fake Survey Generator React frontend with Vite and TypeScript. Use this skill when frontend code changes need to be compiled and validated for TypeScript errors. This skill orchestrates the npm build command and reports build errors.
Generate complete production-ready SaaS boilerplate with authentication, database schemas, billing integration (Stripe), multi-tenancy, API routes, dashboard UI, and deployment configuration. Supports Next.js App Router, TypeScript, Tailwind, shadcn/ui, Drizzle ORM, and multiple auth/payment providers. Use when starting a new SaaS product, subscription app, or multi-tenant platform.
Expert guidance for developing Claude Code hooks in TypeScript with shared utilities, esbuild compilation, and Vitest testing - distributes compiled JS while maintaining TypeScript development experience
JS/TS conventions for syntax, modules, and types. Use when writing or reviewing JavaScript/TypeScript code.
Core React 19 patterns including hooks, Suspense, lazy loading, component structure, TypeScript best practices, and performance optimization. Use when working with React components, hooks, lazy loading, Suspense boundaries, or React-specific TypeScript patterns.
Core Node.js backend patterns for TypeScript applications including async/await error handling, middleware concepts, configuration management, testing strategies, and layered architecture principles. Use when building Node.js backend services, APIs, or microservices.
TypeScript/Node.js API development skills. REST API patterns, Express/Fastify handlers, TypeScript types, Zod validation, and async patterns.
Configures Neon Serverless Driver for Next.js, Vercel Edge Functions, AWS Lambda, and other serverless environments. Installs @neondatabase/serverless, sets up environment variables, and creates working API route examples with TypeScript types. Use when users need to connect their application to Neon, fetch or query data from a Neon database, integrate Neon with Next.js or serverless frameworks, or set up database access in edge/serverless environments where traditional PostgreSQL clients don't work.
Comprehensive error handling patterns for Python and TypeScript applications. Use this skill whenever writing try/catch blocks, creating custom error classes, implementing retry logic, designing error boundaries in React, building API error responses, or handling failures gracefully. Trigger for any code dealing with exceptions, error propagation, graceful degradation, or fault tolerance.
Trigger this skill whenever working with TypeScript files (.ts, .tsx), configuring tsconfig.json, or using TypeScript-specific features like strict typing, generics, utility types, or type guards. Activate for any TypeScript project setup, type definition authoring, Zod schema validation, or discriminated union patterns. Also use when the user asks about avoiding `any`, enabling strict mode, or migrating JavaScript to TypeScript.
