From 391c4bba327bbb59a64d352da2b670892a4e2e67 Mon Sep 17 00:00:00 2001 From: "prompt.ac/@jeffrey" Date: Thu, 8 Oct 2026 11:46:06 -0700 Subject: [PATCH] Add browser: safari to puppet, driving real desktop Safari Every puppet browser verb takes browser: chrome (default, CDP daemon) or safari. Safari runs through AppleScript do JavaScript against the logged-in session, with native CGEvent clicks/keys in frame's screen space under the shared input lease. Semantic snapshot/click/fill/wait keep the strict locator contract; choose and upload stay Chrome-only.
