Process and generate multimedia content using Google Gemini API. Capabilities include analyze audio files (transcription with timestamps, summarization, speech understanding, music/sound analysis up to 9.5 hours), understand images (captioning, object detection, OCR, visual Q&A, segmentation), process videos (scene detection, Q&A, temporal analysis, YouTube URLs, up to 6 hours), extract from documents (PDF tables, forms, charts, diagrams, multi-page), generate images (text-to-image, editing, composition, refinement). Use when working with audio/video files, analyzing images or screenshots, processing PDF documents, extracting structured data from media, creating images from text prompts, or implementing multimodal AI features. Supports multiple models (Gemini 2.5/2.0) with context windows up to 2M tokens.

Implements scalable icon systems with SVG sprites or React/Vue components. Use when setting up icon libraries, creating icon sizing tokens, optimizing SVGs, or building accessible icon buttons.

Use for token-expensive operations requiring multi-file analysis - codebase exploration, broad searches, architecture understanding, tracing flows, finding implementations across files. Uses MCP cursor-agent server (company pays) with clean async interface. Do NOT use for single-file analysis, explaining code already in immediate context, or pure reasoning tasks.

Design and implement RESTful backend API endpoints following REST principles and conventions. When creating or modifying API endpoints, route handlers, controllers, or any files that define HTTP endpoints (e.g., routes.ts, api.ts, controllers/*, handlers/*). When working on files that handle HTTP requests and responses, implement versioning strategies, or define resource-based URL structures. When building REST APIs with proper HTTP methods (GET, POST, PUT, PATCH, DELETE), implementing query parameter handling for filtering and pagination, or setting up rate limiting and HTTP status code responses.

OAuth 2.1 Bearer Token usage guide. Use when implementing access token transmission, Authorization header support, resource server validation, and security requirements. Covers query parameter prohibition and token protection. Based on OAuth 2.1 Section 5 requirements.

Generate a structured user story map to visualize workflows, user goals, and release slices.

Bitcoin trading simulation with technical analysis (EMA/RSI/Bollinger), Monte Carlo projections, and Telegram alerts. Cambodian market focus (USD/KHR 4050).TRIGGERS: BTC backtesting, indicator calculations, Fear & Greed integration, crypto strategy development, CoinGecko/Alternative.me APIs, portfolio simulation, trailing stop optimization, Sharpe/drawdown metrics.ENTRY POINTS: btc_trader.py (365d backtest), btc_simulation.py (60d Monte Carlo), backtest_runner.py (advanced metrics).

Ability to design, implement, test, deploy, and maintain software systems that meet defined requirements. Includes translating specifications into executable code, applying appropriate programming and design practices, managing changes over time, and operating software in production environments. Applies across application, platform, and infrastructure-adjacent contexts and is independent of specific languages, frameworks, or tools. Work may be performed individually or collaboratively and may be supported by automation or artificial intelligence, with human accountability retained for correctness, security, and outcomes.

Authoring CLAUDE.md Project Instructions. Design project-specific AI guidance, document workflows, define architecture patterns. Use when creating CLAUDE.md files for projects, documenting team standards, or establishing AI collaboration guidelines.

Use during REFACTOR phase of TDD or when code duplication is suspected. Defines search-first workflow and safe refactoring practices.

Master database design and management. Learn SQL, PostgreSQL, MongoDB, Redis, data modeling, performance optimization, replication, and blockchain technology.

TypeScript coding conventions and best practices. Use when working with TypeScript files, defining types, or setting up TypeScript projects.

Guides users in creating rich domain models with behavior, value objects, and domain logic. Activates when users define domain entities, business rules, or validation logic.

Triggers on keywords Shelby dApp, build on Shelby, Shelby application, Petra wallet, browser storage, web3 app, decentralized app Shelby, React Shelby, Vue Shelby.

Complete GitHub integration for repositories, issues, PRs, workflows, and security. Use when working with GitHub: (1) Repository operations - get/create files, branches, search code, (2) Issue management - list, create, update, comment on issues, (3) Pull requests - create, review, merge PRs, check CI status, (4) GitHub Actions - list workflows, view runs, download logs, trigger workflows, (5) Code security - Dependabot alerts, code scanning, secret scanning. Requires GITHUB_TOKEN environment variable with appropriate scopes.

Analyzes codebase for theme consistency, checking CSS variables, color usage, and design token adherence across components

Use this skill when building Model Context Protocol (MCP) servers on Cloudflare Workers. This skill should be used when deploying remote MCP servers with TypeScript, implementing OAuth authentication (GitHub, Google, Azure, etc.), using Durable Objects for stateful MCP servers, implementing WebSocket hibernation for cost optimization, or configuring dual transport methods (SSE + Streamable HTTP). The skill prevents 15+ common errors including McpAgent class export issues, OAuth redirect URI mismatches, WebSocket state loss, Durable Objects binding errors, and CORS configuration mistakes. Includes production-tested templates for basic MCP servers, OAuth proxy integration, stateful servers with Durable Objects, and complete wrangler.jsonc configurations. Covers all 4 authentication patterns: token validation, remote OAuth with DCR, OAuth proxy (workers-oauth-provider), and full OAuth provider implementation. Self-contained with Worker and Durable Objects basics. Token efficiency: ~87% savings (40k → 5k tokens).

Master .NET async/await patterns including Task-based Asynchronous Pattern (TAP), ValueTask optimization, ConfigureAwait usage, cancellation tokens, parallel processing, and avoiding deadlocks in ASP.NET Core applications for maximum performance and responsiveness.

Create, update, and maintain specialized AI agent prompts stored in XML and Markdown formats. This skill covers agent role definitions, capabilities, constraints, and best practices for agent prompt authoring. Use when creating new agent prompts, updating existing agents, understanding agent roles, or when users mention agent creation, agent prompts, or role-based AI systems.
