What it actually did when run

observed

Loaded in a sandbox with no network, a read-only filesystem and a recording stand-in for pi's API. This is what it called — not what the source suggests it might.

Events subscribed session_starttool_calltool_resultuser_bash

APIs called getFlagregisterCommandregisterFlagui.notifyui.setStatusui.theme.fg

1 call the source scan did not predict

ui.theme.fg

Reached through a value the scan could not follow — passed as an argument, stored on another object, or returned by a helper.

Run against version 1.0.2 on 2026-08-02. Registration-time behaviour under default settings; other configurations may differ.
