Comments
Selecting text in an artifact opens a small toolbox above the selection. Press Add comment to open a form with the quoted passage shown above the input. Submit the comment to create a thread anchored to that exact text.
The toolbox
Select any passage of more than a few characters and the toolbox appears. It has two actions:
The form shows the quoted text in a highlighted block. Type your message and press the send button (or ⌘Enter) to post the comment.
Thread sheet
Clicking a comment anchor on the page opens the thread sheet on the right. Each thread shows its status at the top:
Use the reply field at the bottom of the sheet to add a message to the thread. You can edit your own messages after posting.
Resolving a thread
Open the thread and press Resolve. Only the person who opened the thread can resolve it. Resolved threads are hidden from the default view; select Show resolved at the top of the thread list to bring them back.
A thread becomes Outdated when the text it was anchored to is removed or substantially changed. Outdated threads are visible in the list but cannot be resolved; they close when the anchor text is restored.
Comments and artifact status
Reviewers can leave comments during the review phase. A comment submitted with a revision request can cause the builder agent to re-open the artifact for edits, returning its status to changes_requested. This happens when a comment is dispatched to the agent via the review flow, not from every comment posted.
FAQ
Who can comment on an artifact?
Any project member with read access to the artifact can leave comments. Resolving requires authoring the thread.
Can I comment on a canvas artifact?
Canvas artifact types have a separate Comments tab in the design canvas. Text-selection comments work the same way on the canvas as on a document.
