Show HN: Harness Relay – the coding agents you have, working together
One kind of agent is enough for a team: all of one kind, or any mix of Claude Code, Codex, Grok, Cursor Agent, Antigravity, GitHub Copilot CLI, Muse Code and five open-source coding agents on your own model backends. For each question, the lead agent designs the team: each member’s role and model, and how they take turns. Once you confirm it, the real agents on your machine work on your code, or any question, and answer each other.
