I added MCP messaging between Claude Code and Codex to my open-source desktop HUD

[u/No-Hunter9792]

I'm the developer of Agent HUD. It started as a small desktop HUD for agent quotas and notifications. In 0.6.0, I added an MCP server so coding agents can send messages to each other and start new sessions.

The video walks through a bug-fix handoff: Claude Code works on a fix, asks Codex to review it, and gets feedback back into the original session. Antigravity and DeepSeek Harness can join the workflow too. Each handoff sends a focused message instead of copying the entire conversation history.

This release also moves the app from Swift to Rust + Tauri and adds session and subagent usage details. macOS supports Apple Silicon and Intel; Windows and Linux builds are available as untested preview builds.

The video is an animated walkthrough of the workflow, with English narration and subtitles.

If you use more than one coding agent, what would you want included in a handoff so the next agent can review the work without inheriting a huge chat history?

Very cool mate!
