From cb9a290158aba61334b1f55020a2b3a9410f1a15 Mon Sep 17 00:00:00 2001 From: Shy Alter Date: Fri, 31 Jul 2026 12:21:24 +0200 Subject: [PATCH 1/2] feat(tasks): surface comment mentions in the activity feed and let the author forward them PostHog Code writes comments on a task's artifacts and canvases to the shared comments table, but the desktop app reads its own activity feed rather than the notifications inbox. A mention on one of those comments therefore fanned out to email and the web inbox and appeared nowhere in the app the comment was written in. Mentions on those comments now project into the mentioned users' task activity feeds, so they land where the comment is readable. Resolving a comment to its task needs help: artifact and canvas ids live in a run's JSON rather than a table, so the client names the task in item_context, and the backend checks it against the team before writing anything. Visibility is left to the read path, which already re-checks it, so a row stays honest when a task's visibility changes later. TaskActivity gains a nullable comment reference so these rows carry an author and a preview like thread-message rows do. The task's author can also now send one of those comments into the task's live run, the same shape as forwarding a thread message: author-only, live run required, and at most once per comment. Forwarding names a stored comment instead of carrying its text, so the wording and the author are read from the database and a caller cannot dress arbitrary text up as a teammate's comment. Forwarded text is now fenced in a labelled block rather than concatenated behind a "[Thread comment from X]" prefix, matching how channel context and custom instructions are already framed, with the closing delimiter stripped from the body so a comment cannot close the block early and have the rest read as instructions. This covers thread messages too.
