+## Posting results to Gitea
+
+After presenting results to the user, post the review as a PR comment:
+
+```bash
+tea comment --login schweitz --repo jpmschweitzer/settled-reach <PR_NUMBER> "<review markdown>"
+```
+
+Use a heredoc for multi-line review bodies:
+```bash
+tea comment --login schweitz --repo jpmschweitzer/settled-reach <PR_NUMBER> "$(cat <<'REVIEW'
+## Dual-Agent Review: <branch> -> main
+...review content...
+REVIEW
+)"
+```
+
+Note: `tea pr reject` does not work on your own PRs. Use `tea comment` instead.
