Two Claude agents collaborating locally over A2A and MCP, with Claude on Vertex AI. A runnable reference + MCP skill for Claude Code, Codex, and opencode.
Let your coding agents talk to each other: search every Claude Code / Codex / Gemini / Cursor session and message live sessions. CLI · MCP · hooks · HTTP/SSE · A2A.
Open-source packages for .agt agent names: @agtnames/resolver, @agtnames/mcp (MCP server, com.agtnames/agt), @agtnames/countersign, the agt-names skill and the manifest spec
Run many AIs on one board and keep control of all of it. Deterministic code decides who acts — never a model. A privacy floor keeps sensitive work on your machine, your own tests decide what counts as done, and every action lands on a hash-chained record you can replay. Free, macOS today; cross-platform and teams next.
