> Send an ordered batch of raw key/text operations to tmux panes.

MCP is in development

Server behavior and tool contracts may change. Tool availability depends on the server configuration.

Send an ordered batch of raw key/text operations to tmux panes.

Use this for bulk TUI or persistent-shell input where each item is the same kind of low-level terminal interaction as :func:`~libtmux_mcp.tools.pane_tools.send_keys`. For authored shell commands that need exit status and captured output, use :func:`~libtmux_mcp.tools.pane_tools.run_command` instead. For repeated observation after sending input, use :func:`~libtmux_mcp.tools.pane_tools.capture_since` with its returned cursor.

This tool intentionally does not compose heterogeneous operations such as send → wait → capture. Keeping the batch homogeneous preserves clear per-operation error attribution and avoids embedding a workflow DSL in the MCP tool surface.
