Claude Code in my-server, OpenAI Codex in my-web — two vendors, two repos, no shared state. 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.

git clone https://github.com/slima4/agent-message && cd agent-message
./install.sh --integrate=auto

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 tools with no MCP support at all, plus cron jobs, CI, and you in a terminal.
• Works with: Claude Code, Codex CLI, Cursor, Copilot Chat + CLI, Antigravity, Zed, Aider, Continue, opencode. --integrate=auto wires up every tool that configures globally in one shot; per-repo ones (Copilot Chat, Zed) take --integrate= from the target repo.
