(That trigger whenever skills trigger, just like classic LLM skills)\n\nI'll be around to answer any questions! Love any feedback or future directions you might be interested in.\n\nComments URL: [https://news.ycombinator.com/item?id=49539111](https://news.ycombinator.com/item?id=49539111)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-sleeper-agents-in-robot-dogs-and-kinetic-prompt-injections", "canonical_source": "https://eito.substack.com/p/kinetic-prompt-injections-and-sleeper", "published_at": "2026-09-02 16:56:18+00:00", "updated_at": "2026-09-02 17:22:55.065322+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-safety", "ai-research", "robotics"], "entities": ["Gemini Robotics 2.0", "MUJOCO"], "alternates": {"html": "https://wpnews.pro/news/show-hn-sleeper-agents-in-robot-dogs-and-kinetic-prompt-injections", "markdown": "https://wpnews.pro/news/show-hn-sleeper-agents-in-robot-dogs-and-kinetic-prompt-injections.md", "text": "https://wpnews.pro/news/show-hn-sleeper-agents-in-robot-dogs-and-kinetic-prompt-injections.txt", "jsonld": "https://wpnews.pro/news/show-hn-sleeper-agents-in-robot-dogs-and-kinetic-prompt-injections.jsonld"}}
