From 2ea7344eac90ea41497f57ea35f8b246a4ad212f Mon Sep 17 00:00:00 2001 From: Lily Shen <115414357+lilyshen0722@users.noreply.github.com> Date: Fri, 30 Oct 2026 12:41:16 -0700 Subject: [PATCH 1/2] docs(review): answer CodeRabbit inside the thread; address it only by command (D199) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CodeRabbit reads in-thread replies and @coderabbitai commands, nothing else. The old fallback let a PR comment that quoted a thread's link count as its answer, and seats turned it into letters opening "CodeRabbit, re review …" that CodeRabbit never reads. - external-review.md: an answer is an in-thread reply; a PR comment is a record for people only and counts for nothing; a top-level comment for CodeRabbit is @coderabbitai plus a command from its reference (checked 2026-10-30, linked); review-body findings have no thread. - coderabbit-threads status: counts only in-thread replies from anyone but CodeRabbit. Drops the issue_comment trigger and the PR-comment scan.
