Use when styling artifacts with professional themes. Triggers include requests to style slides, docs, reports, HTML landing pages, or any visual artifact with consistent colors and fonts. Provides 10 pre-set professional themes with curated color palettes and font pairings, or generate custom themes on-the-fly.
Use when designing new high-level system architecture, reviewing existing designs, or making architectural decisions. Invoke to create architecture diagrams, write Architecture Decision Records (ADRs), evaluate technology trade-offs, design component interactions, and plan for scalability. Use for system design, architecture review, microservices structuring, ADR authoring, scalability planning, and infrastructure pattern selection — distinct from code-level design patterns or database-only design tasks.
Use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.
Use when building MCP (Model Context Protocol) servers to enable LLMs to interact with external services through well-designed tools. Triggers include requests to create MCP servers, integrate external APIs or services, or build MCP tools in Python (FastMCP) or Node/TypeScript (MCP SDK).
Use when building elaborate, multi-component HTML artifacts using modern frontend technologies (React, Tailwind CSS, shadcn/ui). Triggers include requests for complex web artifacts requiring state management, routing, or shadcn/ui components. Not for simple single-file HTML/JSX artifacts — use direct generation for those.
Use when co-authoring documentation with users through a structured workflow. Triggers include requests to write documentation, proposals, technical specs, decision docs, RFCs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers.
Use when creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Triggers include requests for generative art, algorithmic art, flow fields, particle systems, or any art created through code. Always create original algorithmic art — never copy existing artists' work to avoid copyright violations.
Use when creating new opencode skills, modifying existing skills, or measuring skill performance. Triggers include requests to create a skill from scratch, edit or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
