What's Wrong?

Asked Claude Code to "start a draft review and add comments" on a GitHub Enterprise PR. It called gh api pulls/{n}/reviews with "event": "COMMENT" and a "draft": true field it assumed would keep it pending. draft isn't a real parameter on that endpoint, and setting event submits the review immediately — so a live review with inline comments was published under my account without confirmation. The review couldn't be un-published or deleted afterward since GitHub Enterprise's delete-review API only works on PENDING reviews, not submitted ones.

What Should Happen?

PR comments should have been created in a draft PR review.
