Get current weather conditions for a location. Use this skill when users ask about weather, temperature, current conditions, forecasts, or any weather-related queries like "What's the weather?", "Is it raining?", "How hot is it outside?", "What's the temperature?", or "Should I bring an umbrella?". Supports automatic location detection via IP or specific location queries.

Design and build reusable, composable UI components with clear interfaces and single responsibilities. When creating or modifying React components, Vue components, or any UI component files. When working on files that define reusable UI elements (*.tsx, *.jsx, *.vue, components/*). When structuring component props, state management, or component composition. When building component libraries, designing component APIs, or refactoring UI code into smaller components. When implementing hooks, context, or passing data between components.

Annotate passing code with protection levels (@protected/@immutable/@maintainable). Use when stabilizing working features to prevent regressions.

This skill should be used when the user asks to "detect asyncpg usage", "find asyncpg patterns", "scan for asyncpg imports", or "identify asyncpg database code in FastAPI projects". It automatically scans Python files to identify asyncpg imports, connection patterns, and query execution methods that need conversion to SQLAlchemy.

AI-powered Unity development toolkit with Model Context Protocol integration

Comprehensive PDF manipulation toolkit for extracting text and tables, creating new PDFs, merging/splitting documents, and handling forms. Use when Claude needs to fill in a PDF form or programmatically process, generate, or analyze PDF documents at scale.

Core design principles for creating distinctive, beautiful UIs with technical excellence.Combines creative direction with practical foundation for memorable, accessible interfaces.Use when building UI without specific design specs (Figma, screenshots, design files):- Creating landing pages, home pages, marketing pages from scratch- Building web apps, dashboards, admin panels without design- Choosing design system: typography, colors, spacing, visual hierarchy- Need to propose complete design (fonts, colors, layout, spacing)- Building distinctive UIs that avoid generic AI aestheticsKeywords: landing page, design system, typography, colors, spacing, visual hierarchyTwo-part approach:1. Creative Direction: Choose aesthetic tone (minimal, bold, elegant, playful)2. Technical Foundation: Spacing scales, typography specs, WCAG contrast, hierarchyGoal: Create UIs that are BOTH beautiful (distinctive, memorable) AND correct (accessible, consistent, professional).

Comprehensive guide to Claude Code's extensibility features including subagents, skills, plugins, commands, hooks, MCP servers, permissions, and automation. Use when the user asks about Claude Code features, capabilities, customization, extensibility, how to extend Claude Code, or automation workflows.

Maintain a single deployable artifact while enforcing strong internal boundaries between modules.

Implement comprehensive input validation on server-side with complementary client-side validation for user experience, using allowlists, type checking, and sanitization to prevent injection attacks. Use this skill when validating user inputs, form data, API requests, file uploads, query parameters, or any external data entering the application. Apply this skill when implementing server-side validation as the primary security layer, adding client-side validation for immediate user feedback, validating data types and formats, checking ranges and required fields, sanitizing inputs to prevent SQL injection and XSS attacks, using allowlists over blocklists, providing field-specific error messages, or enforcing business rules at appropriate application layers. This skill ensures validation happens at all entry points consistently, security is never dependent on client-side checks alone, users receive helpful immediate feedback, and data integrity is maintained through multiple layers of validation.

Use after planning or implementing non-trivial tasks - runs Codex MCP background verification/review for quality gates (plan validation + implementation review)

Data validation and pipeline testing utilities for ML training projects. Validates datasets, model checkpoints, training pipelines, and dependencies. Use when validating training data, checking model outputs, testing ML pipelines, verifying dependencies, debugging training failures, or ensuring data quality before training.
