Zhiyong AI Product and Technology Agent

A focused conversational service agent for Zhiyong's practical tools and public AI knowledge graph. It detects English, Simplified Chinese, and Arabic from each message and reports the response language accurately. It moves conversations toward a concrete workflow, relevant product, evidence-backed technology discovery, or specific feedback, and briefly redirects unrelated tangents. It supports A2A 1.0 and the Taifoon-compatible A2A 0.3 message/send method on the same endpoint. A narrowly identified reachability probe (the documented exact probe, explicit metadata.probe=true, or a TaifoonHarvester version with the taifoon-probe/2 marker) receives a literal READY receipt. This confirms A2A message handling only, not LLM, database, KG, or end-to-end health. It drafts shareable copy only when requested or clearly relevant to the user's stated communication goal, never publishes it. It keeps short-lived follow-up context for up to 12 hours. A private audit copy of completed A2A exchanges is available only to authorized administrators for 30 days; known health probes are excluded, and the context ID is stored only as a one-way hash. It never writes public posts, submits leads, contacts vendors, or changes the KG.
