Submit a formal review from Files changed, or leave an inline review comment; neither requires an @mention. To request work from Conversation, include @labor0-bot plus a meaningful instruction in the comment.

Reviews from collaborators with Write, Maintain, or Admin access are handled automatically. Ask a question for an explanation, or request a code change and Labor0 will evaluate it and update this pull request when appropriate.

Successful change requests update the branch without a routine completion reply. Labor0 replies to questions and non-actionable feedback and resolves each processed inline review thread unless clarification is required. Conversation comments have no review thread to resolve. Automated review boilerplate paired with selected inline feedback does not receive a separate reply. Related feedback may be handled together, so wait for any necessary replies, new commits, and required checks before merging.
