From 3a4f59069ea4743e4d46e015ae06d641d856a8f0 Mon Sep 17 00:00:00 2001 From: Arshdeep singh Date: Sun, 13 Sep 2026 20:57:23 +0530 Subject: [PATCH 1/2] fix(cursor-plugin): read get_call_run fields from result{} The Cursor skill still taught top-level summary/transcript and had no untrusted-output boundary. Align it with the live envelope and the skills.sh skill, and stop treating extra MCP tools as workflow tools.
