From fe2a4792143e7644d1bcb1bee6143525888ad29c Mon Sep 17 00:00:00 2001 From: "Matt Roberts (Agent)" Date: Fri, 13 Nov 2026 16:48:55 +0000 Subject: [PATCH] feat(mandla): change PRs open with a plain summary (decision 77) Mandla's PR descriptions started with the gateway's ids and file-by-file mechanics, so it was hard to tell what a PR was for. submit_change now needs a one-paragraph plain summary, which the gateway puts first in the PR description and in the commit message. It refuses a summary that is missing, over 600 characters, more than one paragraph, or mentions an internal id.
