Page By Page Recommendation Interaction Simulation With Multi Action Responses

via “user-interaction-simulation”

Model Context Protocol servers for Playwright

Unique: Wraps Playwright's action APIs with automatic element waiting and focus management, allowing LLMs to issue high-level interaction commands ('fill form field X with value Y') without managing low-level event sequencing, element visibility checks, or focus state

vs others: Provides atomic interaction primitives (click, type, select) as separate MCP tools with built-in element waiting and error handling, reducing the complexity of multi-step interaction workflows compared to frameworks requiring manual event orchestration

via “page-by-page recommendation interaction simulation with multi-action responses”

Recommender system simulator with 1,000 agents

Unique: Models recommendation interactions as multi-action sequences where agents see paginated results and decide which items to engage with and how (watch, rate, evaluate, exit), rather than single-item binary responses. The LLM generates actions conditioned on the agent's persona, memory, and the full page context, enabling realistic browsing behavior where users selectively engage with recommendations.

vs others: More realistic than single-action simulators (e.g., click/no-click) because it captures diverse user behaviors, but more computationally expensive due to multiple LLM calls per page and higher decision complexity.
