Also allows eg:

  (with-eval-after-load 'nerd-icons
    (defun agent-shell-make-clock-outline-frames ()
      "Return a vector of nerd-font clock outline icons from one to twelve o'clock.
Uses the nf-md-clock_time_*_outline icons from the nerd-icons package."
      (vconcat
       (mapcar
        (lambda (hour-name)
          (nerd-icons-mdicon
           (format "nf-md-clock_time_%s_outline" hour-name)))
        '("one" "two" "three" "four" "five" "six"
          "seven" "eight" "nine" "ten" "eleven" "twelve"))))
    (setq agent-shell-busy-indicator-frames (agent-shell-make-clock-outline-frames)))

for:

(ok that screenshot came out a bit wee)

lol, ok ;)

One thing, since we're now exposing the frames vector, perhaps we should expose it as a list instead which is more commonly known/used.

agent-shell--status-frame to agent-shell--busy-frame or agent-shell--busy-indicator-frame

agent-shell--busy-indicator-frame SGTM

And :status-frame to :busy-indicator-frame in the header model, or leave as is?

Ah. Yes. That too please.

Should be good to go.

@xenodium gentle nudge?

Emacs 31 supports the below new libraries which I've been using on macOS (they also support MS-Windows and D-Bus based docks on GNU/Linux), to indicate long-running operations like compiles, etc., and to block system from sleeping during long-running operations. It might be nice to integrate them into agent-shell.
