{"slug": "show-hn-beeline-multiplayer-agent-harness", "title": "Show HN: Beeline Multiplayer Agent Harness", "summary": "Beeline launched as an open-source multiplayer agent harness that gives teams a single control plane for both human and agent contributors, supporting Codex, Claude Code, opencode, pi, and goose subscriptions. The project's creator said Beeline was built with early versions of itself and includes a new primitive called workflows, described as skills for teams of agents, plus agent authentication through trustysquire.ai. The tool is positioned as a focused product-team harness rather than a Slack substitute, and the creator noted it still has many bugs.", "body_md": "Shipped Beeline today. It's a team chat for humans and agents - a kind of multiplayer harness. You can bring your codex, Claude code, opencode subscriptions and also works with pi and goose. We built beeline itself with early versions of beeline, and use it to build our other projects - it's boosted productivity quite a bit for us.\n\nDemo video: [https://youtu.be/ACdelpZC2z4?is=pP6MFxJODvKcGjQt](https://youtu.be/ACdelpZC2z4?is=pP6MFxJODvKcGjQt)\n\nThe key insight is that humans do their best work in teams, but agentic development has so far been single player. This has led to people having to forward AI slop to each other or to try to deliver context through various shims like meetings or task tickets.\n\nBeeline is a single control plane for your entire team, both human and agent, and is designed to help your team do its best work.\n\nThings to expect: - This is a multiplayer agentic harness, not a slack substitute. It's best for focused product teams doing or relying on engineering tools and shipping code. - Open source and not a business. We use beeline internally, and just thought it would be a really cool thing to exist in the world. There are still lots of bugs - Sweepstakes things like computer use, lots of third party connector integrations are there. What's cool is that beeline agents can automate _auth_ through trustysquire.ai - they can sign up to most services and APIs without you having to do it for them. - A new primitive called workflows, that are skills for teams of agents. - multi way call with your entire team, humans and agents. I like it quite a bit.\n\nLooking forward to feedback!\n\nComments URL: [https://news.ycombinator.com/item?id=50113268](https://news.ycombinator.com/item?id=50113268)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-beeline-multiplayer-agent-harness", "canonical_source": "https://usebeeline.app", "published_at": "2026-10-16 02:38:15+00:00", "updated_at": "2026-10-16 03:02:06.766162+00:00", "lang": "en", "topics": ["ai-agents", "ai-tools", "developer-tools", "artificial-intelligence"], "entities": ["Beeline", "Codex", "Claude Code", "opencode", "pi", "goose", "trustysquire.ai", "Hacker News"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-hn-beeline-multiplayer-agent-harness", "markdown": "https://wpnews.pro/news/show-hn-beeline-multiplayer-agent-harness.md", "text": "https://wpnews.pro/news/show-hn-beeline-multiplayer-agent-harness.txt", "jsonld": "https://wpnews.pro/news/show-hn-beeline-multiplayer-agent-harness.jsonld"}}
