The developer warns that the tool should only be used with fully trusted parties, since it is \"essentially inviting prompt injection if it's not someone you trust completely.\" The Show HN post received 3 points and 3 comments on Hacker News.", "body_md": "Little experiment I've been cooking up.\n\nI often find myself wanting to do one of the following:\n\n- Get my agent and a someone else's agent to agree on something, after we've been discussing the same topic in different threads\n\n- Give someone temporary access to talk to one of my agents for a specific purpose, to help them do something or help them understand something\n\n- Ask a co-worker for access to chat with their agent, to understand something it has been working on without it having to dump out its entire context into a shared doc\n\n- Give two different agents working for me the ability to quickly chat to resolve something when they have overlapping concerns\n\nSo I built [https://peertalk.ai](https://peertalk.ai) to let agents talk to each other over WebRTC.\n\nObviously only use this if you fully trust the other person. There are lots of safeguards, but this is essentially inviting prompt injection if it's not someone you trust completely -- or an agent fully under your control.\n\nHope people find this helpful! Pretty early days so very open to your feedback and ideas.\n\nComments URL: [https://news.ycombinator.com/item?id=49862920](https://news.ycombinator.com/item?id=49862920)\n\nPoints: 3\n\n# Comments: 3", "url": "https://wpnews.pro/news/show-hn-peertalk-ai-let-your-agent-talk-to-a-friend-s-agent", "canonical_source": "https://peertalk.ai", "published_at": "2026-09-27 02:56:26+00:00", "updated_at": "2026-09-27 03:30:50.943819+00:00", "lang": "en", "topics": ["ai-agents", "agent-protocols", "ai-tools", "ai-safety"], "entities": ["PeerTalk.ai", "WebRTC", "Hacker News"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-hn-peertalk-ai-let-your-agent-talk-to-a-friend-s-agent", "markdown": "https://wpnews.pro/news/show-hn-peertalk-ai-let-your-agent-talk-to-a-friend-s-agent.md", "text": "https://wpnews.pro/news/show-hn-peertalk-ai-let-your-agent-talk-to-a-friend-s-agent.txt", "jsonld": "https://wpnews.pro/news/show-hn-peertalk-ai-let-your-agent-talk-to-a-friend-s-agent.jsonld"}}
