One skill to let AI agents work as peers: make Codex and Claude talk to each other

I use Claude Code and Codex side by side, and I got tired of copy-pasting between two apps every time I wanted one to pick up where the other left off, do some task, or perform a review. So I wrote a skill that lets them hand work to each other directly. The skill implements some plumbing around agents' CLIs, so that they can communicate efficiently. You tell a primary agent something like "ask Codex to implement this" or "have Claude review this diff." It runs the other one through its actual CLI (using your subscription), streams the work back so you (and a primary agent) can monitor it, and remembers the session ID of the secondary agent's chat, so the next message from the primary agent continues it instead of re-explaining everything. It goes both ways, and adding a new agent is just a small adapter drop-in, so Gemini Antigravity will be added soon. You can point the other agent at building something, reviewing your code, or trying to break it. npx skills add kununu/agent-bridge -g -a claude-code codex It's Open Source MIT. Curious whether it's useful to anyone else, and open to feedback.
