libtmux:delete-buffer

Delete the literal named buffer, or the current top buffer; return an outcome. Named deletion requires a live tmux 3.4+ daemon because 3.3a can delete the top buffer when the supplied name is missing. On 3.3a, an explicit NAME signals UNSUPPORTED-CAPABILITY before payload dispatch; omission still deletes the top buffer. A name identifies the buffer at dispatch, not an earlier incarnation. Signals an operational condition on failure; never retries an unknown deletion.
