From fe03b01c98050b8e72bb8c88b507313b23a74c23 Mon Sep 17 00:00:00 2001 From: Vu Anh Phung Date: Tue, 10 Nov 2026 22:41:24 +0000 Subject: [PATCH] ci: apply engineer bot learnings from #565 and #567 Read the PR branch tip in reviewer follow-ups, load .bot/ from main in engineer follow-ups, deny agent writes to .bot/, and merge main into bot PRs whose only conflict is new changelog entries. Tune the bot prompts for test level, fix choice, stale reviews and review scope, and record driver pitfalls for all bots.
