description: "Point at something on the human's macOS screen with a big arrow and a sign (\"Franz, click HERE\"), and hand over values, secrets and questions on a floating cue card, using the bigarrow CLI. Use whenever the human has to look at, click, type into or choose a specific spot, button, field, window, tab or menu: show me where, point to it, which button, where do I click, zeig mir wo, guide me through this UI, the human must approve or sign something, or you need the human's hand and they may not be looking at the terminal; also to hand over credentials, a password, token, 2FA code, IBAN or command to paste, or to ask the human a question or a choice while they are away from the terminal. Mandatory when it is time-critical: a code that expires, a login or payment page that times out, a build waiting on the human."

# big-arrow

`bigarrow` draws a click-through arrow with a sign, needs no permission and never takes the
focus. Point at the thing itself, a line in the terminal is easy to miss.

Needs bigarrow 0.5.1 or newer. If `bigarrow --version` prints an older one, run
`brew upgrade franzenzenhofer/tap/bigarrow` first: an old binary has no `card` and prints
`{{value}}` as plain text.

```bash
open "x-apple.systempreferences:com.apple.preference.security?Privacy_ScreenCapture"
bigarrow start --element "Ghostty" --app "System Settings" --text "Franz, switch this on: Ghostty may record your screen" --say
# watch for the result (page changed, job continued, file appeared), then:
bigarrow stop
```

## Rules

- Open the exact pane or URL yourself, then point at the one control left for the human. Never
  walk them through menus. The human clicks; you point.
- The sign is one full sentence naming the action ("Franz, click Save", never "here"). When the
  click approves, grants, pays, signs, sends or deletes, add what happens: "Franz, click Pay:
  49 EUR to Hetzner". The human decides; the facts go on the sign, not only in the terminal.
- `--say` when the human may not be looking. Time-critical (code expires, page times out, job
  waits): `--color red --say` and say by when: "Franz, enter the 2FA code now, it expires in 60 s".
- Something to paste (a command you may not run, a URL, a code): put it on the sign as
  `{{value}}`. The human sees the value on a copy button (no braces); one click copies all of it
  and the arrow stays. Point at where it goes: "Franz, copy {{sudo xcodebuild -license accept}}
  and paste it here", then check that it was pasted.
- One arrow per step; `bigarrow stop` the moment the step is done. Arrows also end alone: after
  300 s, when your session exits, when the human answers (hook below).
- A click on the sign or shaft, except a copy button, removes the arrow (target clicks pass
  through). A removed arrow was seen: check the result, do not redraw. Skip `--close-button`
  unless asked.
