# T3 Code Run T3 Code as a sandbox-local browser harness. Treat it as a long-running process: start it in tmux, report the pairing URL, and leave the session running for the operator to open at `localhost:3773` through their host/VS Code port forwarding. ## Arguments Arguments received: `$ARGUMENTS` - `ACTION`: optional first positional argument; default `start` - `start`: start T3 Code in tmux, or report the existing session - `status`: show whether the tmux session is running and print recent output - `url`: print the latest pairing URL from the log/pane if present - `logs`: print recent log lines - `stop`: kill the tmux session - `attach`: print the attach command; do not attach from an agent run - `help`: print script usage - `--session`: tmux session name; default `agent-t3code` - `--port`: expected UI port; default `3773` - `--log`: log file; default `/tmp/<session>.log` If the user does not specify an action, use `start`. ## Preconditions Before launch, remind the user that T3 Code is a UI over an existing provider.

It starts a browser UI and prints a single-use pairing URL such as `http://localhost:3773/pair#token=...`. ## Run Run the bundled script with the received arguments: ```bash bash "$CLAUDE_SKILL_DIR/scri...
