Iterative web game development with Playwright-based testing, screenshot validation, and deterministic time-stepping. \n \n Provides a structured workflow: implement small changes, run automated Playwright tests with controlled input bursts and frame pauses, capture screenshots and text state, then inspect and adjust \n Requires window.render_game_to_text() to expose game state as JSON and window.advanceTime(ms) for deterministic frame stepping during automated tests \n Includes a Playwright cli

For conceptual questions ("How does Ownable work?"), explain without generating code. For implementation requests, proceed with the workflow below.

Implement Subframe designs with business logic into your codebase. \n \n Fetches designs via MCP from Subframe by URL, page ID, or name, then syncs required components locally \n Detects project state and guides you through either full Subframe integration or using designs as inspiration in existing non-Subframe projects \n Handles component syncing, page creation in the correct directory structure, and preservation of existing business logic when updating designs \n Provides patterns for adding

Development and validation scripts for AI SDK functions across multiple providers and capabilities. \n \n Organized by AI SDK function category (text generation, streaming, structured output, embeddings, image generation, speech, transcription, reranking, and agents) \n File naming convention maps provider and feature combinations (e.g., openai-tool-call.ts , amazon-bedrock-anthropic-cache-control.ts ) for quick identification \n Includes shared utility helpers for error handling, environment lo
