High-performance reinforcement learning framework optimized for speed and scale. Use when you need fast parallel training, vectorized environments, multi-agent systems, or integration with game environments (Atari, Procgen, NetHack). Achieves 2-10x speedups over standard implementations. For quick prototyping or standard algorithm implementations with extensive documentation, use stable-baselines3 instead.
Framework for building LLM-powered applications with agents, chains, and RAG. Supports multiple providers (OpenAI, Anthropic, Google), 500+ integrations, ReAct agents, tool calling, memory management, and vector store retrieval. Use for building chatbots, question-answering systems, autonomous agents, or RAG applications. Best for rapid prototyping and production deployments.
Modern UI/UX design specialist for web applications, mobile apps, and design systems. Covers design principles, user research, interaction patterns, accessibility (WCAG), responsive design, component libraries (Tailwind, shadcn/ui, Material), prototyping, and usability testing. Creates beautiful, functional interfaces following best practices.
Create videos from a text prompt using HeyGen's Video Agent. Use when: (1) Creating a video from a description or idea, (2) Generating explainer, demo, or marketing videos from a prompt, (3) Making a video without specifying exact avatars, voices, or scenes, (4) Quick video prototyping or drafts, (5) One-shot prompt-to-video generation, (6) User says "make me a video" or "create a video about X".
Sketch a UI design as a throwaway `.openui` file in `docs/prototype/` for the developer to render live in the Genui VS Code extension. Use when the user wants to see a design, sketch a screen, mock up a layout, compare a few options, or says "genui this", "sketch a [page]", "mock up [thing]", "let me see a few options", "prototype this design", "draft a UI". This is specifically for visual UI mockups rendered by the Genui extension, not terminal logic prototyping.
Expert in building custom tools that solve your own problems first. The best products often start as personal tools - scratch your own itch, build for yourself, then discover others have the same itch. Covers rapid prototyping, local-first apps, CLI tools, scripts that grow into products, and the art of dogfooding. Use when: build a tool, personal tool, scratch my itch, solve my problem, CLI tool.
Creates and manages ephemeral Neon databases for testing, CI/CD pipelines, and isolated development environments. Use when building temporary databases for automated tests or rapid prototyping.
Create or modify vanilla HTML/CSS/JavaScript (without a framework) using modular ES modules (ESM), vanilla technologies, clean and readable code, ready for production (no transpiling). Useful for lightweight, high-performance pages, dependency-free UI widgets, standard JavaScript refactoring, and rapid prototyping without using frameworks like React, Angular or Vue.
Use Codex CLI for sandboxed auditing, debugging, and autonomous prototyping
Run single-file C# programs as scripts for quick experimentation, prototyping, and concept testing. Use when the user wants to write and execute a small C# program without creating a full project.
Run OpenCode CLI for code generation, analysis, and development tasks. Uses OAuth authentication. Use for rapid prototyping, code refactoring, testing, and automation. Preferred for load balancing sub-agent work (35% weight).
Provision instant temporary Postgres databases via Claimable Postgres by Neon (pg.new) with no login, signup, or credit card. Use when users ask for a quick Postgres environment, a throwaway DATABASE_URL for prototyping/tests, or "just give me a DB now". Triggers include: "quick postgres", "temporary postgres", "no signup database", "no credit card database", "instant DATABASE_URL".
