Description

A browser-based game where you roll a ball to collect words from a web page, which then serves as context for an AI agent. As the ball grows, it visualizes the narrowing cost gap between Claude Sonnet 5.5 and Opus 5.5 due to Anthropic's prompt caching rates. Clearing the page generates a 'handoff.md' and a performance rank based on context size and cache hits.
