Claude Code sends its API spec with /message-send my-web ; Codex runs /.agent-message-cmd inbox and gets the endpoints, the models, the error codes and a \"no CORS configured\" warning. One shell call each way. 3x speed. Installs everything and wires each globally-configured agent tool found on this machine: a marker block in the tool's rules file, plus a sandbox writable-root in /.codex/config.toml for Codex. All reversible with ./install.sh --uninstall . Plain ./install.sh skips the wiring and just names what it found. - Use case: Claude Code in api/ , Codex CLI in web/ , Cursor in mobile/ — three vendors, one task. Claude finishes the schema change and runs msg send web \"schema: token nullable\" . The Codex agent sees it on its next inbox check and adapts its code. No shared session, no shared vendor, no human relaying between windows. - Why it works everywhere: the transport is a directory of JSONL files and the API is one shell command. No MCP server to register, no per-repo .mcp.json , no token. If an agent can run bash , it can join — including","default_branch":null,"files":null,"tree":[],"storefront":"/r/slima4","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/slima4/agent-message/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
