Run `crit fetch` to pull the latest review comments (it prints the review file path and each comment). If you need the full comment text, read the review file — run `crit status` to find its path. Address each unresolved comment in the relevant file at the referenced location, then reply with `crit comment --reply-to <id> --author 'Claude Code' '<what you did>'`. When all comments are addressed, run `crit share how-to-use-crit.md` to post the updated files and replies back.
