How to show a code on a sign that the person can copy and paste with Big Arrow on the Screen

Put a PIN or code on a sign with a copy button and point at the field to paste it into.

Authorization notice. Big Arrow on the Screen is dual-use. Only use it on software, sites and systems you own or have explicit permission to test.

Credentials. A PIN or code on the sign is visible to anyone who can see the screen, so show it only when the person is alone and clear it afterwards.

Who it is forA person signing in on a website who needs a code from an agent or script, such as a PIN for a sign-in form.

The problemReading a code from one place and typing it into another invites typos, and the agent cannot type into the field for the person.

The outcomeThe sign shows the code with a copy button, and the arrow points at the PIN field until the person pastes the code.

What you need first

  • A Mac running macOS 14 or later
  • Homebrew to run `brew install franzenzenhofer/tap/bigarrow`
  • Claude Code or Codex if you want the agent skill
  • Accessibility permission for the app that starts bigarrow, only for --element and --app App:title targets

Steps

  1. Install the tool with brew install franzenzenhofer/tap/bigarrow.
  2. Run bigarrow start --element "PIN code" --role textfield --app "Google Chrome:Acme sign-in" --from right --color blue --border-color yellow --text-color yellow --text "Franz, copy & paste the PIN {{482913}} here", replacing the field, window and code with yours. (inferred, check the README)
  3. Click the copy button on the sign and paste the code into the field.
  4. Clear the arrow with bigarrow stop --all after the paste. (inferred, check the README)

Prompt for your agent

Use the bigarrow CLI from franzenzenhofer/big-arrow-on-the-screen to point at the text field <field label> in <app name>:<window title> and show the sign "<sign text with {{<code>}}>". Expected output: a sign with a copy button and an exit code of 0. Verify the exit code and do not repeat the code in any other output.

Caveat. The copy button is only created when the code is written as {{value}} inside --text, and it is not a password manager or a secure store.
