Not supported by design: merge, branch/label/release deletion, force push, repo/admin management.

Note: create_issue, add_labels, and remove_labels accept label names; the server resolves them to Gitea label ids and returns a clear error for unknown labels.

Note: the milestone argument on create_issue/update_issue accepts either a numeric milestone id or a milestone title (resolved case-insensitively against open and closed milestones; unknown titles return a clear error). On update_issue, milestone: 0 clears the issue's milestone. Gitea Projects (Kanban boards) are intentionally unsupported: the Gitea REST API exposes no project endpoints.
