Show HN: Agent Buddies – Swappable animated characters for AI agents

A developer released Agent Buddies, an open-source library of 10 original animated characters that display eight shared agent states, driven by a deterministic event stream with no API calls or animation framework. The tool ships a picker with searchable catalog, live previews, remembered favorites and optional developer allowlists, plus local caching, an offline Koko fallback, reduced-motion support and hidden-page pausing; a CLI command, `npx agent-buddies new "a sleepy white cat"`, is in preview with the npm release pending owner review. The project matters to developers building AI agents who want a swappable, user-chosen visual layer without adding network dependencies.
